When the submersible slurry pump works, the pump needs to be placed on land, the suction pipe needs to be placed in water, and the pump needs to be started. Due to the structural limitations of mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, and the pump must be fixed, otherwise the motor will be scrapped if it falls into the water. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.
If there is a spare pump, the two pumps can be used in turn. If the pump is stuck, the pump can only be repaired. A net can be added at the water inlet to prevent too many impurities from entering the pump, so the probability of pump sticking will be much smaller. The pump should be divided into two aspects: electricity and machine. For the machine, you can compare the previous maintenance records. The second is the electrical aspect. We should understand the power of each pump motor and have a certain understanding of its control system.
The slurry pump with mechanical seal must ensure the supply of shaft seal water. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned. When working in different positions, the vertical slurry pump is partially immersed in the pit and can not be completely immersed in the liquid level, and the submersible slurry pump can be completely immersed below the liquid level.
The motor of the vertical slurry pump can use the ordinary vertical motor without waterproof, while the motor shaft and pump shaft of the submersible slurry pump are coaxial, the motor must be waterproof and sealed, and the motor and pump can be immersed in liquid at the same time. In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs fixed installation when in use, while the submersible slurry pump can be used without direct immersion, which is convenient and flexible.
