Solutions to problems of automatic pump

Q1. The pump will not start

A: Reason 1: No power supply.Solution: connect to the power supply

A: Reason 2: The voltage is too low/too high.Disposal method: confirm the voltage is within ±10%

A: Cause 3: High pressure of inlet and outlet pipes.1. Confirm whether the inlet pipe pressure exceeds the service conditions. If the inlet pipe pressure is too high, the pump will lose its pressurization function and will not start.2. If the pressure setting pressure of the pressure switch needs to be increased, please contact the engineer for treatment.3. Note that the pressure adjustment is too high, which will cause the pump to run non-stop.

A: Cause 4: Blocked/stuck pump. Disposal method: turn the screwdriver clockwise at the end of the motor shaft for confirmation and inform the service personnel for maintenance

Stop the pump during the operation

A: Cause 1: The pump is blocked/stuck.Disposal method: turn the screwdriver clockwise at the end of the motor shaft for confirmation and inform the service personnel for maintenance

A: Reason # 2: Motor overload.Solution: Cut off the power supply and restart the power supply. If it cannot start, please inform the maintenance

A: Reason no. 3: Lack of water.Method of the disposal: Check whether the water source and inlet pipe are blocked

A: Cause 4: The temperature control switch jumps due to high water temperature.2. To speed up the start, turn on the faucet first, relieve pressure, then open the plug to fill the water, until the water temperature drops, it will automatically resume operation.(Take precautions to avoid being scalded by hot water)

Q3. The pump starts itself when there is no water

A: Cause 1: water leakage.Solution: Check whether the faucet is closed or the pipe leaks

A: Reason # 2: Failure of the check valve.Disposal method: clean valve parts or update check valves

Q4. Pump starts frequently

A: Cause 1: leakage in inlet pipe or air in water.Disposal method: Check the inlet pipe and water source

A: Reason 2: The water consumption is too small.Solution: Turn the tap on a little bit

A: Cause 3: Loss of pressure in the pressure barrel.Disposal method: Check the pressure of the drum and fill the air

Q5. There is a sense of leakage of electricity

A: Cause: wrong grounding.Disposal method: reconnect the ground wire

Q6. Pump without stopping when there is no water

A: Cause: insufficient water or air.1. Turn off the power and unscrew the exhaust red plug to let the air escape before starting.2. If water is cut off for a long time, please turn off the power supply and send power when the water supply is sufficient.3. Please cancel the ventilation pipe if there is ventilation pipe in the inlet pipe.

Q7. The pump is in normal operation but the water output is insufficient

A: Cause 1: Wrong steering of a three-phase motor. Disposal method: two of the three-phase power supply shall be switched

A: Reason no. 2: Lack of water.Method of the disposal: Check whether the water source and inlet pipe are blocked

A: Reason no. 3: It’s too deep.Solution: Lower the pumping height
