Farmland water conservancy pumpIt is an important equipment for agricultural irrigation and drainage, but various failures will inevitably occur in the process of use. Understanding these failures and their solutions is essential to ensure the normal irrigation of farmland. The failure and solution of farmland water conservancy pump is an important part of farmland irrigation system. The failure of the water pump will cause the farmland to be unable to irrigate normally, thus affecting the growth and yield of crops. This paper will introduce some common water conservancy water pump failure, and provide effective solutions.

1. common faults

1. Water leakage: including mechanical seal leakage, pump shell crack leakage, etc. This may be due to damage to the seal or poor pipe connections. The solution is to check whether the seal is intact, and if it is damaged, it needs to be replaced. At the same time, check whether the pipe connection is tight, if loose should be re-tightened. If there is still a water leakage problem, it is recommended to ask professional and technical personnel for maintenance.

2. Motor failure: such as motor overheating, speed drop, etc.

3. Insufficient flow: It may be due to damage to the impeller, insufficient speed or blockage of the pipeline.

Excessive noise: may be caused by bearing wear, impeller imbalance, etc. Abnormal noise is also one of the common faults when the water pump is running. This may be caused by bearing wear, loose impeller or blockage of the water inlet pipe. The solution is to check whether the water pump bearing is worn, if there is wear, it should be replaced in time. At the same time, check whether the impeller is loose, if loose should be tightened. In addition, check whether the water inlet pipe is blocked, if there is a blockage should be cleaned.

5. Difficulty in starting: It may be a power problem or an internal failure of the motor. One of the common water pump failures is that the water pump cannot start. The cause of this problem may be a power supply failure, poor wire contact, or motor damage. The solution is to first check whether the power socket and power switch are normal to ensure that the power supply is normal. Then check whether the wire connection is firm and rule out the possibility of poor contact. If the above steps are normal, it may be that the pump motor is damaged and needs to be repaired or replaced.

2. Solution

1. Leakage treatment: replace the mechanical seal to ensure tight installation; for cracks in the pump casing, temporary repair with plugging agent can be used, or the pump casing can be replaced.

2. Motor troubleshooting: check the power supply to ensure that the voltage is stable; check the internal circuit of the motor, repair or replace the damaged parts; ensure that the motor has good heat dissipation and avoid long-term overload operation.

3. Flow problem solving: check the impeller and replace it in time if it is damaged; clean the pipeline and remove the blockage; adjust the speed to ensure that it is within a reasonable range.

4. Noise reduction measures: replace worn bearings; balance test the impeller and adjust the center of gravity.

5. Handling of starting difficulties: check the power supply to ensure the normal power supply; Check the motor starting capacitor, if damaged, replace it; Check the internal coil of the motor, repair or replace the damaged part.

3. preventive measures

1. Regular inspection: Regular inspection of farmland water conservancy pumps shall be carried out, and problems found shall be handled in time.

2. Maintenance: Follow the instructions for maintenance, such as replacing lubricating oil, fastening screws, etc.

3. Operation specification: the operator should be familiar with the performance of the equipment and operate according to the specification to avoid the failure caused by misoperation.

4. Environmental factors: to ensure that the pump operating environment is good, to avoid long-term operation in harsh environments.

The failure of farmland water conservancy pump may include problems such as unable to start, water leakage and abnormal noise. For different faults, we can take corresponding solutions, such as checking the power supply, replacing damaged seals, fastening pipe connections, repairing or replacing damaged motors, replacing worn bearings, etc. Timely solve the pump failure can ensure the normal irrigation of farmland, improve the yield of crops.

In short, there are many kinds of failures of farmland water conservancy pumps, and the solutions vary from person to person. In the process of use, maintenance and inspection should be carried out regularly, and problems should be dealt with in time to ensure the normal irrigation and drainage of farmland. At the same time, the operator should be familiar with the performance of the equipment and operate in accordance with the specifications to reduce the occurrence of failures.
