Vane pump is a common fluid conveying equipment, which is widely used in industry, agriculture and daily life. However, in the course of use, the vane pump may have some failures, affecting its normal operation. The following will introduce the common faults of the vane pump and the corresponding solutions.

Common faults of 1. vane pump

1. Insufficient flow: the output flow of the pump does not reach the expected value. The flow rate of the pump is reduced or the liquid cannot be transported normally. This may be caused by the blockage of the inlet valve of the pump, the blockage of the inlet pipeline or the damage of the pump blades.

2. Noise and vibration: abnormal noise and vibration during operation. When you find that the vane pump produces abnormal noise during operation, it may be caused by damage or looseness of the pump blades.

3. Leakage: The pump body is not tightly sealed, causing liquid leakage. The leakage of the pump may come from the aging, wear or damage of the seal.

4. Bearing overheating: The bearing runs for too long or has poor lubrication, resulting in overheating.

5. motor overload: motor current is too large, easy to cause overload. Motor abnormalities may include difficulty in starting the motor, excessive heating during operation, or motor overload.

2. Solution

1. Insufficient traffic solution

Check whether the speed of the pump meets the requirements, clean or replace the blocked inlet pipeline, check the blade wear, and replace it in time if there is wear. The solution includes cleaning the inlet valve, dredging the inlet pipe, and replacing the blade. In the process of cleaning and maintenance, be sure to pay attention to safety and avoid accidents.

2. Noise and vibration solutions

Check whether the installation of the pump is stable, if there is looseness, tighten it, check whether the blades and pump casing are worn, repair or replace if there is wear, check the bearing part of the pump, and repair or replace it in time if there is any problem. The solution is to check the state of the blade. If the blade is found to be damaged, it should be replaced or repaired in time. In addition, should also check whether the connection parts of the pump is tight, such as loose should be tightened.

3. Leakage solution

Check whether the seal is in good condition. If it is damaged, replace it. Check whether the connection of the pump body is tight. If it is loose, tighten it. Select the appropriate sealing material to improve the sealing performance. In order to solve this problem, you can first check the condition of the seal. If you find aging or wear, you should replace it in time. In addition, ensure that the seals are installed correctly, and perform necessary lubrication and maintenance.

4. Bearing overheating solution

Check the lubrication of the bearing. If the lubrication is insufficient, add lubricating oil. Check the wear of the bearing. If there is wear, replace it in time to ensure the smooth operation of the bearing and adjust the gap.

5. Motor overload solution

Check whether the voltage of the motor is stable. If the voltage is too high or too low, it needs to be adjusted. Check the running state of the pump to ensure that the pump will not get stuck or suffer excessive resistance during operation. Check the heat dissipation of the motor to ensure air circulation around the motor. The solution is to check whether the power supply voltage is normal and eliminate the power supply problem. At the same time, check whether the connection of the motor is good and whether the motor needs cleaning and maintenance. If the problem persists, it is recommended to consult a professional technician for help.

The failure of the vane pump may involve noise, leakage, flow reduction and motor abnormality. In the event of these failures, timely and correct solutions can effectively maintain and repair the vane pump to ensure its normal operation. Therefore, regular inspection and maintenance of the vane pump is essential to improve its service life and performance.

In order to ensure the normal operation of the vane pump, regular maintenance and inspection should be paid attention to in daily use. If any abnormal situation is found, it shall be stopped for inspection and treatment in time. At the same time, selecting the appropriate vane pump model and specifications to ensure that it meets the needs of use is also an important measure to prevent failure.
