1无法启动⑴电源供电不正常。原因:1接头连接不牢靠。2开关接触不紧密。3保险丝熔断。4三相供电缺相。⑵机械故障。原因:1填料太紧或叶轮与泵体之间被杂物卡住而堵塞。2泵轴、轴承、减漏环锈住。3泵轴严重弯曲等。排除方法:1放松填料,疏通引水槽。2拆开泵体清除杂物、除锈。3拆下泵轴校正或更换新的泵轴。2提不上水⑴少许空气还残留在进水管或泵体中。水泵启动前未灌满水,看上去灌的水已从放气孔溢出,但未转动 1 can not start ⑴ power supply is not normal. Cause: 1 connector is not secure. 2 switch contact is not close. 3 fuse blown. 4 three-phase power supply phase loss. ⑵ mechanical failure. Reason: 1 packing is too tight or jammed between the impeller and pump body blockage. 2 pump shaft, bearing, leakage ring rust live. 3 serious pump shaft bending. Remedy: 1 relax the filler, clear the trough. 2 open the pump body to remove debris, rust. 3 Remove the pump shaft and correct or replace the new pump shaft. 2 can not mention the water ⑴ a little air still remain in the inlet pipe or pump body. The pump was not filled with water before it started, and it appeared that the irrigation water had spilled from the vent but did not rotate
