Slurry pump operation, the pump needs to be placed on land, suction pipe on the water, but also need to start the pump. Mud pump and submerged slurry pump because of structural constraints, things need to be placed on the water above the surface, the pump into the water, it must be fixed, otherwise, the motor fell into the water will cause the motor scrapped. And because the long axis length is generally fixed, so the pump installation and use of more trouble, applications have been a lot of restrictions. If there is spare pump, it is best to use two pumps in turn. If the card pump is only to repair the pump, you can add a net inlet, not to allow excessive impurities into the pump, so the probability of card pump will be much smaller! Pump to be divided into two aspects of electricity and machine, for the machine, the main maintenance records before transferred out to know about it. Followed by the electrical aspects, and to understand the power of each pump motor, to his control system have a certain understanding. The use of mechanical seal of the slurry pump, shaft seal water supply must be guaranteed. Non-water-free operation, otherwise the mechanical seal will be destroyed.
