      The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.   there are two different installation methods, fixed automatic coupling installation system and mobile free installation system.  It is not correct that it has no effect on us.equipment maintenance ,  Reasonable.   one method is to use ultrasonic method to detect whether the equipment has cavitation. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, many pumps tend to have better measurement results when in use.  When the water level reaches, the frequency of the frequency converter drops, and the slurry pump operates at a low speed. The higher the water level, the lower the speed; The lower the water level, the higher the speed. At the same time, the water level signal is transmitted to the control cabinet so that the operators can timely understand the liquid level. Through this control the circulation in the slag slurry pool is basically unchanged
