Abstract：Zaohe pumping station in Jiangsu province is the largest mixing flow pumping station.The working security checkup weightily affects the content and profoundity of the updating and rebuilding items.Taking Zaohe pumping station as example,at the base of all-around investigation,we analysed the content and item of testing.Aiming at the characteristic of large-scale machinery, we adopted the international advanced virtual apparatus to test the machinery vibration.Besides,we did the frequency and wavelet analyses with advanced software.Safety appraisal is made to be advanced according to specific condition of the pumping station,and not be confined to operate at 25 years afterwards.Zaohe pumping station unit is operated at relative stabilized unit of 8 pump blades.pumping station machinery;vibration;noise;safety appraisal
