The cause and elimination of the failure of the pump
Reason 1: The inlet valve is not opened, the inlet and outlet pipelines are blocked, and the impeller flow channel is blocked. Treatment method: check and remove the obstruction.
Reason 2: The motor runs in the wrong direction, and the speed of the motor phase loss is very slow. Treatment method: adjust the direction of the motor and tighten the motor wiring.
Cause 3: The suction pipe is leaking. Treatment method: Tighten each sealing surface to eliminate air.
Reason 4: The pump is not filled with liquid, and there is air in the pump cavity. Treatment method: Open the upper cover of the pump or open the exhaust valve to exhaust the air.
Reason 5: Insufficient water supply at the inlet, excessive suction, and leaky bottom valve. Treatment method: shutdown inspection and adjustment (this phenomenon is easy to occur when using the grid-connected water pipe and with suction).
Reason 5: The pipeline resistance is too large, and the pump is not properly selected. Treatment method; reduce pipeline bends and reselect the pump.
Mud Pump Using Tips
1. Always check the reliability of the safety valve, so that the rated pressure of the safety valve does not exceed 70 kg, which is sensitive and reliable.
2. When changing the flow, do not directly shift the gear during work. You must first operate the clutch to disengage the power, and then shift the gear to avoid damage to the gears and parts.
3. The harm caused by the high-pressure pump in use is very great. During operation, we must pay great attention to the high-pressure pump, and try to avoid high pressure and release the pressure in time.
