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　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly, the water supply is not satisfied,BoraWear resistant slurry pump, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.Bora,　　In recent years, domestic stainless steel pipeline pump products have greatly improved their technical level through introduction, absorption, renovation, especially the supporting products of some major technical equipment have reached or approached the advanced level of similar products.　　Therefore,BoraVertical slurry pump, the stator winding will be burnt out due to excessive temperature rise.Kant,　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, the application market of submersible slurry pump is also better than that of vertical pump　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race, bearing gland and retaining sleeve　　 Cutting blades can be selected to cut some large block solid substances into pieces during use, so that blockage can be avoided during reuse.

　　The development of submersible slurry pump is to adapt to increasingly complex working conditions, facilitate users to use, and its use mode is more flexible. And it fills a part of the gap in the application of slurry pump. When the submergence depth is deep and there is no better slurry outlet, that is, the submersible pump will rust and cannot be started. If it is not used for a long time do not immerse it in water for a long time. Put it into clean water and run it for a few minutes to clean the mud inside and outside the pump.　　The vertical sand pump is generally a submersible slurry pump. Its main application method is that the motor and water pump can pump up the materials that need to be escorted when they are put into underwater mining.Work courses,　　 for screws that are too tight or rusted for a long time, the nut can be lubricated with kerosene prepared in advance, or the nut can be gently knocked with a wooden hammer and then removed. This method can also be used in slurry pumps and other places.　　In this way, a smooth surface can be formed on the surface.　　 Then reinstall the equipment on the engine and install the rubber hose.

　　What?Interpretation and observation,　　The premise of using this method is that the water gun must have sufficient flow during use, it will cause the Double Wear of the stator and rotor. Due to the requirements of the processing technology and materials, the　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (aboutBora,　　Submersible slurry pump In addition, it must be used continuously during transportation. If there is an interval in the middle, it must be avoided that the interval is relatively long so as to avoid the solidification of slurry in the pump when the operation is stopped.　　Function of shaft seal of submersible slurry pump: the main of shaft seal is to prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump.　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, the outlet valve of the final stage pump can be gradually opened. The speed of opening the valve should be controlled by the fact that the pump does not vibrate and the motor of any stage does not exceed the rated current.
