Abstract In order to obtain the running effect and its relationship with various factors of light hose-fed traveling sprinkler system, according to light hose-fed traveling sprinkler system working perfor-mance, we selected 6 different inlet pressures and 4 different walking gears to test and measure inlet pressure, traveling speed and flow uniformity and pressure sprinkler intensity and analyzed the relationship between them. The results show that inlet pressure and flow present a positive linear correlation. Moreover, speed and inlet pressure also present a positive linear correlation under 4 different gears. CU was computed to find no correlation with inlet pressure, gears(traveling speed), friction loses. CU is only affected by this system′s device. The sprinkling condition is stable in the whole test. Running effects can meet the design demand. CU was up to 89.5%, which is the highest value of CU, when inlet pressure was 0.45 MPa. Irrigation depth was affected by discharge and traveling speed. When discharge was set to a constant, irrigation depth was reduced with the traveling speed increasing, presenting a curve downward trend.
