Agricultural water pump faults and troubleshooting

Troubleshooting methods for the causes of faults

The water pump does not produce water

Or the water production is insufficient 1. The air in the pump cavity or suction pipe is not Drain 1. Fill the hand exhaust pump with water, move the pressure handle up and down, and drain the air in the pump chamber and suction pipeline.

2. Air leakage in the suction pipeline or hand exhaust pump 2. Check the water suction pipeline (including the hand-operated exhaust pump) and seal it

3. The water pump runs with excessive head 3. Reduce the head

4. The pump shaft speed is not enough 4. Increase the pump speed to Rated speed

5. The seal is damaged 5. Replace the seal

6. The water level is low 6. Reduce the installation height of the pump

7. Self-priming pump The amount of water injected is small or there is no water in the leakage. 7. Fill the pump cavity with water, or ensure that the pump cavity and water suction pipeline do not leak.

The water pump bearing is overheated. 1. Insufficient or no lubricating oil. 1. Add more water. Lubricating oil

2. The bearings are seriously worn or damaged 2. Replace the bearings

The internal combustion engine emits black smoke 1. The flow rate is too large or the lift is too low 1. Reduce the flow rate or increase the lift

2. The power of the internal combustion engine is not enough 2. Replace the internal combustion engine

Water comes out after stopping the pump

There is no water in the pipeline 1. The valve plate of the water outlet valve is damaged 1. Replace the valve plate< /p>

Micropump faults and troubleshooting

Troubleshooting methods for fault phenomena

Not starting 1. Low voltage 1. Replace copper core wires with more than 2 square meters and shorten the wires as much as possible Length

Cannot absorb water 1. The suction pipe is leaking 1. Check the joint and make sure it is sealed.

2. The seal is leaking 2. Replace the seal

3. The water level is low 3. Reduce the installation height of the pump

4. The gas in the pump chamber is not drained 4. Refill water and exhaust

Insufficient flow 1. Low water level 1. Reduce the height of the pump installation

2. The outlet pipe is too long 2. Shorten the outlet pipe

3. The pipeline is clogged 3. Clear foreign matter (including impeller)

4. Low voltage 4. Replace the thick wire (same as above)

The motor stops intermittently 1. The voltage is low 1. Replace Thick wires (same as above)

Pipeline pump tea stove pump faults and troubleshooting

Troubleshooting methods for causes of faults

Motor stops 1. Low voltage 1. Avoid using Electricity peak

2. The centrifugal switch fails 2. Adjust the centrifugal switch

3. The wire is thin, resulting in a large starting voltage drop. 3. Replace more than 2 square meters of wire

4. Mechanical parts are stuck. 4. Adjust the gap, clean, remove rust and remove oil.

5. Capacitor breakdown 5. Replace new capacitor

6. The circuit is not connected 6. Check the wires and connect the circuit

The pump does not produce water 1. There is air in the pump cavity that has not been removed. 1. The pump cavity is filled with water and the air is removed

2. The suction pipe is leaking. 2. Check the joint water valve to make it sealed

3. Inside the pump The seal is leaking 3. Adjust and replace the seal

4. The water pressure in the outlet pipe is too high 4. Reduce the pressure in the outlet pipe (unscrew the water valve)

The motor stops overheating 1. Voltage Too low 1. Adjust the voltage or avoid peak power consumption

2. Motor overload (large friction resistance, large flow) 2. Reduce mechanical friction or reduce flow

Insufficient flow 1. Partial blockage 1. Remove foreign matter

2. Large resistance loss in the pipeline 2. Shorten the pipeline and change the hard bend of the pipeline

3. The water temperature is too high or the pressure in the outlet pipe is too high High 3. Reduce the water temperature or the pressure in the outlet pipe

4. The opening of the water valve on the pipeline is insufficient 4. Unscrew the water valve

Self-priming pump faults and troubleshooting

Troubleshooting methods

The motor does not start 1. The circuit is blocked 1. Check the wires

2. The mechanical parts are stuck 2. Clear the obstacles

3. The voltage is too low 3. Avoid the peak electricity consumption

4. The wires are thin 4. Replace the copper core wires with more than 2 square millimeters

Cannot absorb water 1. The water suction pipe leaks 1 .Find the leaking part and seal it

2. The water level is lower than the pump suction lift 2. Reduce the installation height of the pump

3. The pump cavity is short of water 3. Open the water filling plug and drain the pump Fill the cavity with water

Open the faucet

Water does not come out immediately 1. Check valve leaks 1. Disassemble the valve and check whether there is any foreign matter stuck or the focus pad is deformed, the nut is loose, etc.

When the faucet is turned on, the water continues to flow out

and the pressure switch does not turn on

or operates frequently

. 1. The pipeline pressure fluctuates, is unstable, and is higher than the switch set pressure, causing the switch to disconnect. 1. Increase the set pressure of the pressure switch appropriately, cut off the power first, remove the transparent cover, and use a screwdriver to turn it in the "+" direction.

2. Open the faucet to reduce the water flow resistance.

Turn off the faucet power

The machine does not stop or turns on and off

Frequent movements

The pipeline pressure fluctuates and is lower than the switch setting pressure , there is no guarantee that the switch is completely disconnected. 1. Check whether the water outlet pipe and faucet are leaking

2. Check whether the pressure tank is leaking

3. Check whether the check valve is leaking

4. Lower the switch pressure value appropriately, cut off the power first, remove the transparent cover, and use a screwdriver to turn it in the direction of the "+" sign.
