Sanitary Rotary Vane Pump Troubleshooting

The use of Sanitary Rotary Lobe Pump has improved our work efficiency and reduced the workload of workers. However, what worries users is that sanitary rotary vane pumps may also fail during work. So what are the common sanitary rotary vane pump failures? Are there any solutions to the failures? I believe these are the information that users want to know very much. These issues will be analyzed next.

1. Failure to start

Reason: The reasons why the sanitary rotary vane pump cannot vibrate include motor or power supply system failure, foreign matter in the rotor parts, bearing jam, and unsatisfactory starting conditions.

Solution: Repair the motor or power supply system, clean the rotor parts, clean or replace the bearings, and check the conditions that should be met. Insufficient flow or no water.

2. Insufficient flow or no water

Reason: Generally, there is debris blocking the suction side or the outlet side or the impeller, excessive wear of the sealing ring, damage to the impeller, incorrect steering, too low accommodation, insufficient flooding depth, and air inhalation.

Solution: clean the filter, impeller, guide vane, discharge pipe, valve system; replace damaged parts; correct the direction; measure voltage, frequency, check the motor; increase the suction water level.

3. The sanitary rotary vane pump vibrates abnormally and makes noise

Solution: It is necessary to increase the suction water level of the sanitary rotary vane pump or close the outlet gate valve, correct the static balance of the impeller, correct the concentricity of the shaft, straighten the shaft, tighten the anchor bolts, replace the bearings, and replace the guide bearings.

The sanitary rotary vane pump is a kind of equipment used to transport clean water and sewage containing certain solid particles, corrosive industrial wastewater and other harsh substances. It plays an important role in sewage treatment, raw water treatment, metallurgical steel industry, mining, power plants, municipal engineering, farmland water conservancy and other fields. It is believed that the failure of the sanitary rotary vane pump will have a great impact on the use of the sanitary rotary vane pump. Accelerating the research on these failures will have a very positive effect on the future of the sanitary rotary vane pump.
