Common failures and troubleshooting methods of agricultural pumps

Agricultural water pump is one of the largest pump dosage on the market products, one of the common agricultural water pumps mainly GDD booster pump, WQG submersible pump, etc., are basically some small volume and light weight of the product in order to use mobile.Some of the common faults in the use of agricultural water pumps in the use of farmers need to understand the following knowledge to solve the common troubleshooting methods of agricultural water pumps:

(1) the agricultural water pump cannot be started.Check whether the connection of farm water pump wire joints is strong and the switch is tight.Repair should be done if there is a broken or poor contact.

(2) water leakage or leakage of the agricultural water pump line may be installed when the bolts are not tightened.If the leakage is not serious, the cement can be used in water leakage or air leakage, and tighten the nut with a wrench.If the water is serious, reload.

(3) severe vibration of agricultural water pump, may be in the electric rotor imbalance, or the coupling combination of bad, bearing wear, bending;It may also be caused by loose moving parts, broken pipes and broken pipe supports.Adjustment, reinforcement, straightening or replacement should be made in different situations.

(4) the agricultural self-priming pump does not absorb water.The reason is that the self-priming pump has air or water intake.Elimination method: first water pressure, then pump body filled water, then boot.At the same time, check whether the check valve is tight, the pipe and joint have air leakage disc, if the leakage is found, then apply the oil or the paint to the head area after disassembly, and tighten the bolt.Check the oil seal ring of the pump shaft, such as wear and tear should replace the new one.

(5) the motor of the agricultural diving sewage pump is overheating.Check the wiring of the diving pump and whether there is any short circuit, check whether the impeller and the impeller cover, the motor stator and the rotor have friction, remove the obstacle in time.

(6) insufficient flow of agricultural water pumps.This is because the head is too high, the line is too long or the line is curved.It should adjust the lift, shorten the pipe of various kinds of pumps or change the bending of the pipe, and also check and remove the blockage of the screen and pipe.
