In some sewage collection and transfer tanks, debris such as finger cots and cloths are often found. These impurities are easily sucked into the impeller by the centrifugal pump. Due to the softness of finger cots, cloths, and other debris, they cannot be thrown out by the impeller and block the impeller inlet.

1. General handling method

The general method is to install a filter screen at the inlet of the pump. But this is a temporary solution without addressing the root cause. The entrance filter will also be safely blocked by these debris. This is essentially no different from the impeller being blocked. Treat headaches with the head, treat feet with the feet.

2. Resulting in consequences

If the valve is blocked like the impeller is blocked, but no one can detect it in time, the centrifugal pump will "shut down", commonly known as "shut down pump". If the phenomenon of "pump tightness" occurs, it can last for more than ten minutes at a fast speed or two hours at a slow speed, and the centrifugal pump seal will burn out and leak water. If it is a metal centrifugal pump, it may still be barely usable. If it is a plastic centrifugal pump, the entire sealing system of the centrifugal pump will completely melt and burn out, and the centrifugal pump will completely "shut down" and cannot be used. At this point, the only option is to shut down and repair the machine seal, which is laborious, time-consuming, and costly.

3. Solution

The third-generation intelligent acid and alkali resistant pump can easily cope with problems such as idling and pump stagnation. Using the second-generation traditional acid and alkali resistant pump, the machine seal does not have intelligent real-time monitoring. No matter how actively it is inspected and checked, there will always be times when the machine seal burns; Using the third-generation intelligent acid and alkali resistant pump, the machine seal has intelligent real-time monitoring, and no active inspection is required. The water pump and machine seal will not have any problems, saving worry, effort, and maintenance.
