What causes the submersible pump to trip when powered on1. Electrical malfunctionShort circuit: Water ingress into the internal coils, cables, or junction boxes of the pump body can cause a short circuit. Use a multi-meter to measure the winding resistance (normally several ohms to tens of ohms, if

The reason for the sudden decrease in water output of the submersible pump1. Impeller or pump body flow channel blockageReason: Impurities (such as water grass, sediment) block the impeller or pump body flow channel, resulting in a decrease in flow rate and head. ‌Solution: Disassemble the pump and

The main reasons why the submersible pump sometimes rotates and sometimes does not rotate include the following:1. Power supply problem: The submersible pump may have difficulty starting due to unstable power supply voltage or power failure. Low or high power supply voltage, damaged cables, poor con

Four major faults of submersible pumps and corresponding measuresThe submersible pump motor cannot start and is accompanied by a buzzing sound:1. Check the motor circuit for one phase open circuit, check the voltage, and check if the voltage is too low.Solution: Repair the circuit and adjust the vol

What are the hazards of submersible pump water hammer?Conditions for water hammer generation:1. Sudden opening or closing of the valve2. Sudden shutdown or startup of submersible pump unit3. Single pipe delivers water to high places (water supply terrain elevation difference exceeds 20m)4. Large tot

Maintenance method of agricultural submersible pump in slack season1. Check vulnerable parts: the impeller, retaining ring, shaft sleeve, bearing seat, etc. of the submersible pump are vulnerable parts. First, remove the water pump and check whether the vulnerable parts are intact. It is forbidden t
