865 Effect of blade slotting on radial thrust of single vane centrifugal pump
SHI Weidong,*,LI Linjian,XU Rongjun,WANG Bin,TAN Linwei,ZHOU Ling
In order to improve the operating characteristics of single vane centrifugal pumps and reduce the radial thrust, the dynamic characteristics of the thrust in a single vane centrifugal pump was analyzed by using a combination method of numerical simulation and experiment. The variation rules of radial thrust were clarified under three flow rate conditions, such as 0.6Qd, 1.0Qd and 1.4Qd. The results show that the static pressure difference across the blade pressure and suction sides mainly attribute to the radial thrust, which achieves the maximum value at a low flow rate. A new method—blade slotting for relieving the radial thrust in the pump was proposed by analyzing and comparing both the experimental and numerical results. Then, one 1.0 mm wide slot was made across the blade at three different circumferential positions selected such as 0°, 90° and 270°, respectively. The influences of the slot position on the radial thrust and pump performance were analyzed. The results show that when the slot is located near blade trailing edge the pump performance is less affected but the pressure difference across the blade pressure and suction sides is reduced greatly, and the radial thrust on the impeller is declined. Consequently, the reliability of single vane centrifugal pump will be improved, and its service life will be extended.

871 Influence of volute cross-sectional area profile on hydraulic performance of double-suction centrifugal pump
ZHAO Wanyong,CHEN Shuai*,ZHAO Qiang,LI Yanbin
Aiming at the problem of shaft breakage caused by the operation of S700-500-730 double-suction centrifugal pump in a pump station, the CFD numerical simulation method is used to analyze the influence of the volute cross-sectional area profile on the hydraulic performance and radial thrust. The original profile(Y-law)adopted in the pump is compared with the volute cross-sectional area li-near profile(L-law). The results show that the pumps with two kinds of volute cross-sectional area profiles share a similar hydraulic performance at the design point, the radial thrust in the pump with Y-law profile is increased by 24.77% compared with the pump with L-law profile. Under off-design conditions, however, compared with the pump with L-law profile, the hydraulic performance of the pump with Y-law profile is more superior, unfortunately, the radial thrust on the impeller is higher than the former.Under unsteady flow conditions, the pulsation amplitude and high frequency pulsation of radial thrust in the pump with Y-law profile are much more severe than the pump with L-law profile. The variation rule of volute cross-sectional area has a significant influence on the radial thrust ac-ting on the impeller. The results can provide a theoretical basis for solving the problem of shaft brea-kage caused by excessive radial thrust.

878 Simulated annealing algorithm-based optimization of crank phase arrangement of quintuple-cylinder reciprocating pump
GAO Jinpeng,YAO Chundong*,LIU Qingyang,LIU Tianming,JIAO Huiming
In order to improve the force distribution on the crankshaft of reciprocating pump and enhance the crankshaft performance, an optimization model of the crank phase arrangement of a reciprocating pump was established based on an analysis of the force and strength of the pump crankshaft. In the model, five initial phase angles of the crank were used as design variables and the maximum bending moment of the critical sections of the crankshaft was the objective function to be minimized. Based on the simulated annealing algorithm, the crank phase arrangement was optimized and two arrangements were obtained. Furthermore, the stress and strength simulation analysis were carried out for the optimized crankshaft. The results show that the optimized crank phase arrangement allows the crankshaft to have the smallest maximum bending moment and the lowest combined bending and torsion stress. Compared with the worst arrangement, the optimal arrangement has effectively alleviated the stress of crankshaft.The method for establishing optimization model of crank phase arrangement herein is universal and applicable to the crankshaft with even more liquid cylinders(five, seven and nine cy-linders)in single or double action reciprocating pumps. The simulated annealing algorithm can optimize crank phase arrangements quickly, but also can obtain the global optimal solution and subjects to a high reliability. It provides a new approach for crank phase arrangement optimization of similar crankshafts.

885 Study on operational efficiency improvement of main drainage pump in coal mines with variable frequency booster pump
DUAN Haipeng*,ZHANG Linwei
At present, the main drainage pump in coal mines is prone to occurrence of cavitation due to limited underground drainage conditions, which can shorten the service life span of the pump significantly. In order to meet the requirements of energy conservation and emission reduction in the underground condition, and improve the inflow condition of the main drainage pump, a pressurized water supply mode was proposed by connecting a booster pump with the main drainage pump in series, and the operation of the booster pump can be controlled fully with a frequency converter. Through a theore-tical analysis, the pump-control-pump technique can change the output pressure of the drainage system, adapt to the performance of a pipeline system, improve the operational efficiency of the system, and ensure that the drainage system works in an efficient region. Based on a comparative analysis of field test, the efficiency of the pump unit composed of the booster pump and the main drainage pump with a less number of stages is improved compared with the main drainage pump with original number of stages, but also the cavitation of the main drainage pump is avoided at the same time. The frequency conversion control of the booster pump can also ensure that the pressure of the main drainage system can be adjustable, so that thesystem can operate in an efficient region to achieve the objective of energy conservation and emission reduction. The results provide a new technical scenario for design and transformation of the drainage system in coal mines.

891 Pressure pulsation characteristics in down-scaled high specific speed centrifugal pump in cavitating state
WANG Kaili,LI Hong*,SHEN Zhenhua
The down-scaled model pump of a high specific speed centrifugal pump was obtained by using the affinity laws for centrifugal pumps. It turned out that the performance curve of the model pump is similar to the original scale pump based on experiments and numerical simulations, and the model pump can replace the original pump for experimental study. Based on the RNG k-ε turbulence model, the incompressible time-average N-S equations of the fluid flow in the pump model were solved by SIMPLEC method. The hydraulic, cavitation performance and pressure pulsation characteristics of the pump were obtained under different operating conditions beads on steady and transient numerical simulations of the flow field in the pump. The accuracy of simulation was validated by comparing the simulated results with the experimental observations. In terms of simulation, the largest pressure pulsation amplitude is seen at the tongue at the rated flow rate. The dominant frequencies of pressure pulsation at each monitoring point under different working conditions are blade passing frequency. The tongue experiences the largest pressure fluctuation, but the impeller inlet is subject to the smallest pressure pulsation. The pressure pulsation amplitude is the smallest under the rated flow rate condition, but significantly increased under off-design conditions. Through the transient numerical simulation at different stages of cavitation, it is found that from non-cavitation to severe cavitation, the pressure pulsation characteristic in frequency domain on the tongue and at the outlet remains unchanged under different working conditions. Specially, the pressure pulsation amplitude decreases with cavitation deve-lopment, and the dominant frequency of the pulsation is the blade passing frequency. And with extending cavitation degree, the high frequency components in the pressure pulsation become rich, and the dominant frequency at each monitoring point drops off significantly. These outcomes can be used as the basis for judging cavitation inception.

898 Response surface method-based optimization of impeller of fluoroplastic two-phase flow centrifugal pump
ZHANG Desheng*,MEI Jian,ZHAO Ruijie,HUANG Jun,JIN Yongxin
Steady two-phase flow in a fluoroplastic two-phase flow centrifugal pump was simulated based on discrete particle model,and the erosion rate in the impeller was predicted by using the Finnie erosion model for abrasive solid particles and the flow filed variables obtained to improve the pump efficiency and reduce the impeller erosion rate.Response surface method was used to establish mathematical models of objective functions in terms of impeller geometric parameters, including blade wrap angle φ, impeller inlet diameter D1, blade inlet angle β1, blade outlet angle β2, impeller outlet diameter D2, and blade outlet width b2. The three-dimensional response surfaces of various objective functions were plotted as a function of the six geometrical parameters in Matlab. Further, these mathematical models were unified in Matlab, and the impeller geometrical parameters of a fluoroplastic two-phase flow centrifugal pump of model SJB400-250-300 were optimized. Finally, the optimal combination of these parameters was obtained.The results show that there are interactions among these parameters. When D1, φ, β1, β2 and b2 are subject to the high levels and D2 is at the low level, the pump can achieve a better comprehensive performance. Compared with the original model, the pump efficiency is increased by 8.98%, and the erosion rate is decreased by 6.64%.By analyzing and summarizing the interactions between the parameters and the multiply objective functions, the influence of the interactions on the objective functions is obtained.These outcomes provide a reliable basis for the optimization design of fluoroplastic two-phase flow centrifugal pumps.

904 Rough-strips height calculation method based on dimensional analysis
ZHANG Honghong,MU Zhenwei*,LI Fanqi,JIA Pingyang,SUN Dexu
In order to study the effect of rough-strip energy dissipator(R-SED)on flow diversion of wide and shallow bends, and to achieve the formulation of R-SED parameters and to improve its applicability, based on the principle of dimensional analysis and 18 sets of orthogonal experiments, a semi-theoretical and semi-empirical formula for R-SED height was established. Each coefficient in the formula was calibrated by combining the orthogonal experimental results. A multiple regression analysis on the formula was performed against the orthogonal experimental results. The formula was compared and validated with the prototype data of the Xinjiang ″635″ spillway renovation project. Moreover, a more intuitive water flux discrete coefficient Cm was introduced to serve as a new type of flow diversion evaluation index. The results show that the Reynolds number Re has little effect on the height of R-SED. If the effect of Re is ignored, the predicted R-SED heights with the formula are basically consistent with the prototype data. The average relative error between them is 7.77% only, hence Cm can reflect the diversion effect of R-SED objectively. Since each parameter has real physical meaning during derivation of the formula, Cm has universality in terms of the methods for evaluating the diversion effect of general rectification engineering.

910 Two-dimensional mathematical model of sedimentation in hydropower station reservoirs
HONG Zhenguo
The sedimentation of a hydropower station reservoir was simulated through a two-dimensional mathematical model. The simulated river reach starts from about 600 m upstream the dam and terminates at about 400 m downstream. The calculation sections are 20 large sections with an ave-rage interval of 500 m in the reservoir divided by using a 1:2 000 topographic map. Additionally, the feasibility of simulating changes of sedimentation in the reservoir by the mathematical model is validated through the model test. The results show that the reservoir sedimentation is in delta sedimentation pattern. When the reservoir is operated for 1 year, the delta head keeps moving downstream, and finally reaches front of the dam with an elevation as high as 1 347 m. While the sedimentation in the reservoir develops to the high beach at the tail of the reservoir and the ″tail up″ phenomenon is obvious. After the reservoir has been operated for 1 year, the sand discharge ratio is stable at more than 90%. After the reservoir reaches the balance of scouring and silting, the operation mode of ″storing clean and discharging muddy″ is adopted to wash the sand. A scouring funnel is formed in front of the bottom hole for flood discharge and sand flushing. The funnel has a three-dimensional shape. The gradient along the flow direction is about 1∶50-1∶70, and the side slope is about 1∶3.5-1∶4.5. The intake is basically within the scope of scouring funnel, which can keep the taken water ″clean in front of the gate″. The sedimentation based on the mathematical model is basically consistent with the model test results, and it is feasible to simulate the change of reservoir sedimentation.

915 Investigation into sealing performance of lip seals with surface texture when considering temperature effect
ZHANG Fuying,YANG Junmei,*,SHUI Haoche,DONG Chengcheng,
Based on elastohydrodynamic lubrication theory and pumping mechanism of rotary shaft seal, a numerical mixed lubrication model of sealing area in an oil seal was established by comprehensively considering the influence of surface roughness and texture of seal lip. In the model, fluid mechanics, deformation analysis, contact mechanics, temperature and energy conservation equation and viscous-temperature equation are coupled. By solving the numerical equations iteratively, the temperature distributions in oil seal lips with different surface textures(circular, square, equilateral triangle)and the maximum temperatures of oil seal lip under different rotational speeds were obtained. The effects of surface texture on temperature of oil seal contact surfaces and the influences of temperature rise on the sealing performance of the oil sea such as pumping rate, oil film thickness, friction torque, etc were compared and analyzed. The results show that with the increase of rotational speed, the maximum lip temperature rises linearly, and the surface texture obviously raises the lip temperature. When the oil seal is working, the temperature of the friction surfaces rises sharply from both sides to the middle, and the temperature in the texture area increases noticeably, but there is no statistics significance between three textures. The temperature rise leads to a decrease in pumping rate, oil film thickness and lip sealing pressure in the oil seals with three textures, and significantly degrades their sealing perfor-mance.

922 Experiment on influences of number of blades on aeration performance of inverted-umbrella aerator
LIU Houlin,SHANG Huanhuan,TANG Xiaochen,ZHANG Xing,DONG Liang*,GUO Jinnan,WANG Wensheng
In order to study the influence of the number of blades on the aeration performance of inverted umbrella aerator under various flow conditions, two impellers respectively with 6 blades and 8 blades were fabricated for an inverted umbrella aerator. Then, dissolved oxygen experiments were carried out to study the aeration performance of the aerator. The total oxygen transfer coefficient, standard oxygenation capacity and standard dynamic efficiency were measured at two numbers of blades by changing liquid level height in the aeration tank and immersed depth of the aerator. At the same rotative speed, the 8-blade aerator is subject to significantly higher standard oxygen total transfer coefficient and standard oxygenation capacity than the 6-blade aerator. When the number of blades increases, the impellers have a stronger throwing and sprinkling strength, but also the contact area between the liquid and the air is expanded, thus a greatly improving efficiency of oxygen mass transfer is resulted. Additionally, the fluctuation of the liquid near the free surface is intensified, the interaction between the liquid and the bubbles becomes stronger, thus the turbulent mass transfer is enhanced. However, the increase in the number of blades will consume more power, consequently, the standard power efficiency of two aerators with two numbers of blades shows a little difference at an identical rotative speed. Nevertheless, the study provides a certain reference for the economical operation of an inverted-umbrella aerator.

933 Effects of mist spray on photosynthetic characteristics, yield and quality of grape
ZHENG Ming,ZHANG Jianghui,BAI Yungang*,LIU Hongbo,DING Ping
In order to study the effects of drip irrigation(irrigation method)+ mist spray(cooling and humidifying measures)on the photosynthetic characteristics, physiological indexes, yield and quality of grape, three treatments(WP1, WP2 and WP3)and a control(CK)were set up in experiments. The photosynthetic characteristics, grain volume, yield and quality of grape in these treatments were measured during fruit swelling period. The results showed that the daily variation of intercellular CO2 concentration in the mist spray treatments was lower than in the control, and the lowest concentration of intercellular CO2 occurred in WP1 treatment. The net photosynthetic rate of all the treatments showed an M-shaped profile, i.e. the phenomenon called ″midday depression″ appeared at 14:00. In the mist spray treatments, however, the time for ″midday depression″ was shorter than in the control, further, the net photosynthetic rate in WP1 treatment decreased slightly at 14:00. The growth rate and fruit grain volume were in a rank of WP1, WP2, WP3 and CK from the largest to smallest, and the growth rate of fruit grain volume in each treatment reached the maximum on July 15. The yield and quality of each treatment were evaluated by using entropy method, and the corresponding scores were in a rank like WP1, WP2, CK and WP3 from the highest to the lowest. It was suggested that an appropriate mist spray could significantly improve net photosynthetic rate, growth rate of fruit grain volume and fruit grain vo-lume, yield and quality of grape. However, a longer mist spray could also reduce grape yield and qua-lity, so a mist spray for 1 hour per day was the best.

939 Method for constructing farmland electronic map based on micro-irrigation engineering design data
LI Renlu,WAN Shuqin*,KANG Yuehu,LI Xiaobin
In view of high cost of electronic map acquisition in farmland with micro irrigation equipment, a method for rapidly constructing electronic map of farmland based on micro-irrigation enginee-ring design data was proposed. There are some differences in models and expressions of various spatial elements between micro-irrigation engineering design data and farmland electronic map data, especially there are exaggeration, simplification and omission etc for spatial elements in micro-irrigation equipment in the micro irrigation engineering design data. Importantly, there is often a lack of geographic location information description for micro irrigation equipment and other spatial elements in the data. Considering those key points, based on the systematic understanding of micro-irrigation engineering, and through an in-depth analysis of the differences between data model and element expression between design data and farmland electronic map data, an analytical transform method is present in this paper. In the method the dwgdirect.net class library was combined with user programs of ArcGIS Engine to convert the design data in CAD format to the geodatabase format supported by GIS. As a result, a micro irrigation engineering farmland electronic map was preliminarily constructed, and provides a reference for micro-irrigation engineering construction, but also supplies basic data of farmland electronic map to precision agriculture.

945 Effects of different modifiers on water-salt transport characteristics in coastal saline-alkaline soils
XIANG Longkang,GAO Peiling,*,ZHANG Qingwen,ZHAO Yadong,WANG Shibin,YANG Daming
In order to explore the effects of surface layer(0-20 cm)mixed with different modifiers on salinized soil improvement, taking the moderate saline-alkaline soil in the Yellow River Delta as the research object, and one-dimensional vertical water infiltration experiments were conducted. Two modifiers were added to the surface layer, namely river sand and biochar and seven treatments, including CK, S1, S2, S3, C1, C2 and C3 were set up to study their improvement effects. Under different river sand and biochar dosages, two modifiers can improve soil water infiltration performance. Among them, the modifier biochar can significantly increase the water content in the mixing layer, and the modifier river sand can considerably raise the soil water content below the sand mixed layer. Across different treatments, the modifier river sand is more conducive to desalination of saline-alkali soils than the modifier biochar. Specially, the average desalination rate of treatment S3 is(14.5-27.7)% higher than that the treatments with biochar, and both the depth of the desalting zone and the depth of the standard desalting zone exceed the 0-50 cm soil layer with relatively high root density. Through the results of indoor one-dimensional vertical water infiltration test on the river sand and biochar, it is showed that the added sand to the soil surface layer can effectively improve the water and salt distribution of salinized soil in the Yellow River Delta, and provides a good environment for crop growth.

951 Essential element leaching law of slate under different environmental conditions
LI Wangcheng,DONG Yaping*,LI Chen,WANG Shuangtao,ZHAO Yan,WANG Xing
Indoor simulation experiments were conducted to study leaching law of essential element from slate under different environmental conditions. The gray-green slate rock samples taken from Xiangshan area were divided into three groups: distilled water dry-wet cycle group, distilled water freeze-thaw cycle group and brackish water freeze-thaw cycle group. The weathering process of slate was simulated through conducting 50 cycle tests on three groups of the samples. Before a test cycle started, the basic physical property constants of the slate were measured, and its microstructure was analyzed with scanning electron microscopy(SEM). During the test, the electrical conductivity(EC)and the essential element composition and content in leaching solution of the slate were measured regularly. Through experiments it is found that the EC values of the leaching solutions of three groups rise with increasing the number of cycles under the existing experimental conditions. The ranking of the number and the kinds of essential elements leached is different from each other in three groups. However, the ranking and the leached content of each elements and the ranking of the number and the types of essential element with more leached content are not different from one group to another. The ranking of three groups is ZLDR, ZLGS, WXDR from the largest to the least in terms of accumulated leached content of essential elements. The accumulated leached content of essential elements is in a logarithmic relationship with the number of test cycles.

WANG Jiaming,CHEN Si,JING Teng,WANG Hao,HE Zhaoming*
In view of the problems such as high labor intensity, low precision, and insufficient intelligence in irrigation control mode of soilless culture in China, a remote irrigation control system was designed for soilless culture in this paper. The single chip microcomputer MSP430 is the core of detection and control, and performs the drive control of irrigation components, and combines with corresponding sensors to acquire monitoring parameters of nutrient solution in real time. The upper computer software was designed based on Qt programming to monitor the irrigation status of crops. The software has a number of functions, for example, setting of monitoring values, selection of irrigation modes, real-time display of monitoring parameters, data storage and query of historical data and so on. GPRS wireless transmission technology was used for synchronous data communication between the upper and lower computers. Back propagation(BP)neural network was applied to the regulation of conductivity(EC)and pH values of nutrient solution. The monitoring value regulating experiments showed that the system could realize remote stable monitoring and control, the regulation errors in EC and pH values were no more than 0.11 mS/cm and 0.08, respectively.

966 Optimization of structural parameters of capillary jet tee and experimental validation
WANG Xuan,WANG Xinkun*,FAN Erdong,XU Shengrong,XUE Zilong,ZHANG Chenxi,DING Shiwei
In order to improve pulse characteristics of capillary jet tee, 25 sets of capillary jet tee mo-dels were designed by using the method of orthogonal design of experiments in the paper. In the designs, six geometrical factors, namely, nozzle width, nozzle depth, control tube width, position difference, laying length and side wall angle, were selected and 5 levels were specified for each factor. 25 jet tee models were simulated with CFX software. Pulse frequency, head amplitude and pressure diffe-rence were selected as experimental evaluation indexes. The influence of structural parameters on pulse characteristics was analyzed by the range method, and the rank of factors was determined. The statistics significance of the influencing factors was analyzed by using the variance method, and the optimal structure model was determined. Based on the experimental results, at the inlet pressure of 50 to 120 kPa, the pulse frequency of the optimal model was increased by 3 to 10 times/min compared with the 4 mm nozzle width jet tee, the head amplitude was enhanced by 3.2 to 11.1 kPa and the uniformity coefficient of irrigation was better by 0.53% to 1.94%, the flow deviation rate was reduced by 0.81% to 5.33%. The optimized jet tee model can provide continuous and stable pulsed water flow; thus, the pulse performance has been enhanced greatly, which can improve the uniformity of irrigation effectively.
