Vane pump is a kind of centrifugal pump, its working principle is to generate centrifugal force through the rotation of the blades, so as to suck the liquid into the pump body and export its pressure. The impeller of the vane pump has multiple blades, usually 6-12, which can rotate in a fixed cavity in the pump body.

1. maintenance

1. Check the impeller wear: After long-term use, the impeller of the vane pump may wear out. If it is found that the wear is serious, it should be replaced in time.

2. Check the bearing: The bearing is an important part of the vane pump, and long-term operation may cause wear. If the problem is found, the bearing should be replaced in time.

3. Check the seal: damage to the seal may cause leakage of the pump body. Check the seal regularly, if it is damaged, it should be replaced in time.

4. Check the electrical system: check whether the electrical components such as motors and cables are in good condition. If there is any damage, please ask a professional electrician to repair it.

2. maintenance

4. Check the pipeline regularly: check whether the inlet and outlet pipelines are unblocked. If there is any blockage, it should be cleaned in time.

5. Check the bearing temperature regularly: During operation, check the bearing temperature regularly. If the temperature is too high, stop the machine to check the cause and deal with it.

Maintenance when idle: If the vane pump is not used for a long time, it should be turned on regularly to maintain its performance. At the same time, should be stored in a dry, ventilated place, avoid humid environment.

3. considerations

1. In the process of repair and maintenance, the power supply should be cut off to ensure safety.

2. the use of regular manufacturers of accessories and lubricants.

3. Regular inspection and maintenance should be carried out by professionals to ensure correct and safe operation.

4. Vane pump repair requires system exhaust to avoid gas entering the pump body.

5. When repairing the vane pump, it is necessary to use appropriate tools and protective equipment to avoid safety accidents.

6. When replacing the parts of the vane pump, it is necessary to use the same specifications and models as the original to ensure its normal operation.

7. Vane pump maintenance, should pay attention to its external cleaning, to avoid dust or impurities into the pump body.

In short, for the maintenance of the vane pump, professional inspection and maintenance are required, and the operation is carried out in strict accordance with relevant regulations to ensure its normal operation and safety.

Vane water pump is a common water pump, but there will be problems in long-term use. Maintenance can effectively extend the service life of the water pump and save maintenance costs. Attention should be paid to maintenance during use to avoid unnecessary losses.

In short, the repair and maintenance of the vane pump is the key to ensure its normal operation and prolong its service life. Through regular inspection, cleaning, lubrication and replacement of damaged parts, the performance and safety of vane pumps can be ensured. It is recommended that users formulate a detailed repair and maintenance plan according to the usage, and strictly follow the plan.
