In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, corrosion mechanism of water pump and stress characteristics. In order to prolong the service life, protection should be done well, which should be a comprehensive optimization design method.　　What is the solution to this situation?San Rafael Ariba,　　Extractable.　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve, adopt the water level closed-loop control mode, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump, and use the PID adjustment of the frequency converter. WhenOcana,　　 When the power supply voltage is too low, because the pump is also widely used in many rural watering. In this case, it may be lower than the rated voltage, so the current in the stator winding will also be　　The pump can often be selected according to the specific requirements of lift, flow and liquid delivery. The flow range of the delivered liquid is - L / s, and the diesel engine speed range is - rpm. Features: water pump, high automation and performance　　Ordinary vertical motor can be used without waterproof, while the motor shaft and pump shaft of submersible slurry pump are coaxial, so the motor must be waterproof and sealed, and the motor and pump can be immersed in liquid at the same time; The vertical slurry pump is an early product, and the submersible slurry pump is a newly developed product according to the market demand

　　 if the removed gasket is seriously damaged, a new gasket shall be replaced. The removed parts shall be cleaned with kerosene before assembly.　　 there are two different installation methods, fixed automatic coupling installation system and mobile free installation system.　　When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate, the rotating force can be brought to the medium, so thatWorkshop cost,　　If there are sundries blocked the pump will not be filled with water. When this happens again, technicians need to properly adjust the liquid level in the pump sump to a proper height, and check the impeller. In case of damage or aging, it needs to be replaced in time,　　 drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump, so the water ring vacuum pump is used for exhaust to achieve the of water inlet.　　 repair and level the welding part of the submersible slurry pump with a file, clean the part to be bound with alcohol again and wipe it dry.

　　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.Installation materials,　　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　　Automatic pump failure: cause: A. whether the frequency converter has abnormal symbols; b. Whether the actual pressure is higher than the set pressure.　　 If it is found that the impeller is damaged and the liquid supply is insufficient, it is necessary to replace the new impeller in time for use.San Rafael Ariba,　　Potential energy pumping water up high. However, once the pump can not absorb water, the equipment is shaped like a decoration, so what is the reason for this situation? How to solve it?　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started,San Rafael AribaVertical slurry pump,San Rafael AribaFire deep well pump, 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.　　The submersible slurry pump can be used to transport a lot of media containing solid particles when it is used at ordinary times so it has an irreplaceable position when it is used. What is its own structure when it is used.
