China Explosion-Proof Stainless Steel Pipeline Pump Vertical Single Stage Chemical, Find details about China Pipeline Pump, Pumpe and Pipeline from Explosion-Proof Stainless Steel Pipeline Pump Vertical Single Stage Chemical
(1)The inlet valve is not opened, the inlet and outlet pipeline is blocked, and the runner impeller is blocked(2)The running direction of the motor is wrong, and the speed of the motor is slow due to lack of phase (3)Air leakage of suction pipe (4)The suction pump is not filled with liquid and there is air in the pump chamber (5)The inlet water supply is insufficient, the suction head is too high, and the bottom valve leaks (6)The pipeline resistance is too large and the pump selection is improper | (1)Check and remove the blockage(2)Adjust the motor direction and tighten the motor wiring (3)Tighten all sealing surfaces to eliminate air leakage (4)Fill with liquid and open vent valve to exhaust air (5)Shut down, check and adjust (this phenomenon is easy to occur in grid connected water pipe or with suction head) (6)Reduce the pipeline bend, re select the pump | |
(1)First check by reason 1 (2)The impeller of pump channel and pump passage is blocked, scale deposit and valve opening is insufficient (3)The voltage is low (4)Impeller wear | (1)Press 1 to exclude (2)Remove the blockage and readjust the valve opening (3)Voltage stabilization (4)Replace impeller | |
(1)Use in excess of rated flow (2)Suction head too high (3)Pump bearing wear | (1)Adjust the flow and close the outlet valve (2)reduce (3)Replace the bearing | |
(1)Unstable pipeline support (2)Liquid mixed with gas (3)Cavitation is produced (4)Overload heating operation of motor | (1)Secure the piping (2)Increase suction pressure and exhaust (3)Reduce the vacuum (4)Replace the bearing (5)Adjust by pressing 5 | |
(1)Excessive flow, overload operation (2)Rubbing (3)Motor bearing damaged (4)Insufficient voltage | (1)Turn down the outlet valve (2)Check and eliminate (3)Replace the bearing (4)Voltage stabilization | |
6.Water pump leaking | (1)Mechanical seal wear (2)There are sand holes or cracks in the pump body (3)Uneven sealing surface (4)Loose mounting bolts | (1)replace (2)Welding repair or replacement (3)Trimming (4)Fastening |
