Pump routine maintenance and troubleshooting

1. Pump daily maintenance Check the pump power cord, whether there is aging, broken skin, the power cord copper leakage. In this case if the power cord on the shore, you can package the package .If it is better to replace the power in the water Check the water pump impeller or outlet, check the sound of the pump is running sound, if there are unpleasant sound, indicating damage to the pump bearing, the need for repair, refueling, replacement. Check the pump operation If leakage, please send maintenance department overhaul. 2. Pump abnormal noise for three reasons: 1. The pump bearing damage, need to be replaced. 2. The pump impeller loose, grinding to the pump outlet bottom cover. 3. Pump coil damage 3. The pump can not be normal water supply for four reasons 1. Pump Is not a centrifugal pump. Whether it is necessary to divert water, whether the pump is reversed, if it is reversed, replace the capacitor connector method. Three pump outlet or impeller gap whether there is a foreign body. Troubleshooting A no oil discharge 1, the direction of rotation error 2, the pump does not rotate 3, the pump shaft is broken, the rotor does not rotate 4, the suction tube is blocked 5, the fuel tank filter is blocked 6, the fuel tank filter capacity is less than 7, High 8, the number of revolutions less than 9, suction pipe airtight bad 10, the fuel tank filter above the oil surface 11, the blade can not slide out of the rotor slot immediately stop, correct motor rotation direction, if left unchecked will be Burned damaged reasons. Repair the coupling. Repair pump, confirm the number of revolutions, the pressure is above the provisions of the axis is aligned. Inspect the suction line. Clean the filter. Replace the larger capacity, more than double the pump capacity. Change the oil type, set the heater. Specified number of revolutions drive. Inspect the suction line. Refuel to the level meter's baseline. Repair the pump. B noise 1, the suction tube is small, blockage 2, the fuel tank filter is blocked 3, the fuel tank filter capacity is less than 4, the oil viscosity is too high 5, double pump, the suction tube error 6, inhaled air by the suction tube 7, Air is sucked in by the oil seal 8, there is air bubble 9 in the tank, the oil level is too low 10, the vane can not slide out of the vane slot 11, the noise is emitted by the coupling 12, the fuel tank vent hole is blocked or the capacity is less than 13, The provisions of the number of 14, more than the provisions of the pressure 15, bearing wear 16, cam ring wear 17, pump tight tightness 18, pump suction vacuum degree of damage should be 200mmHg the following. Clean the filter. Use a filter that is more than twice the capacity of the pump. Change the oil type, set the heater. Repair piping. Fill in the suction tube, detect the bad place and repair it. Check whether the axis alignment. Check the configuration of the rotary tube. Refuel to the reference level, double pump can not be used separately for different fuel tank. Repair the pump. Coupling damaged new axis misalignment re-assembly. Clean vent or exchange. Check the number of revolutions. Check the pressure gauge. Repair the pump and check if the shaft is aligned. Abnormal wear, Department of oil, oil in the water, oil viscosity and the use of oil temperature. Reassemble the pump to properly tighten the torque wrench. Change the pump. C flow less than 1, no oil discharge 2, the suction vacuum is too large, due to air cavitation caused by cavitation 3, the rotor wear, large internal leakage 4, oil cap tight tight 5, the oil viscosity is too low Check the suction oil filter oil network and configuration (try to use a hose or straight tube). Repair pump properly tightened with torque wrench. Change oil type, install cooler. D seal at the oil spill 1, seal 2, internal leakage replacement oil seal. Repair the pump and check the viscosity of the oil.
