为了更有效的保障排污泵的使用寿命，能够着手改变的就是他的保护系统，主要体现在排污泵在发生泄漏、过载、超温等故障时能进行自动报警,并且能够停机已备维修。
In order to guarantee the service life of sewage pumps more effectively, it is his protection system that can be changed. It mainly reflects that sewage pumps can automatically alarm when leakage, overload, overtemperature and other faults occur, and can stop and be ready for maintenance.
但想要彻底解决这种问题，上诉的方法是很被动的，怎样能够被动变主动呢？就是融入了副叶轮流体动力密封技术以及排污泵的无过载设计技术，从而有效的提高了排污泵的可靠性和承载能力。
But if we want to solve this problem thoroughly, the method of appeal is very passive. How can we change from passive to active? It incorporates the hydrodynamic seal technology of the auxiliary impeller and the non-overload design technology of the sewage pump, thus effectively improving the reliability and load-carrying capacity of the sewage pump.
