No matter how good the pump is, if it is not maintained, it will not achieve higher efficiency. Therefore, we should pay attention to some basic requirements when using the centrifugal pump. The following describes the centrifugal pump to stop working after the request. 1, centrifugal pump should be shut down after the pump inlet valve closed, to be cooled and then turn off the auxiliary system of the valve. 2, high-temperature pump parking should be implemented according to the provisions of technical documents, after parking should be 20-30 min each turn a half turn until the pump body temperature dropped to 50 ℃ so far. 3, cryogenic pump parking, when no special requirements, the pump should always be filled with liquid; suction valve and the discharge valve should be kept normally open state; using double-ended mechanical seal cryogenic pump, liquid level controller and pump seal chamber seal Fluid should maintain pump grouting pressure. 4, conveying easy to crystallize, easy to coagulate, easy precipitation and other media centrifugal pump, stop the pump should be blocked, and timely flush with water or other media pumps and pipes. 5, discharge the liquid stored in the pump to prevent corrosion and cracking. Centrifugal pumps can be widely used in power, metallurgy, coal, building materials and other industries with the transport of solids containing slurry. Such as thermal power plant ash, metallurgical ore dressing plant, coal washing plant coal and heavy medium transport. Centrifugal pump work, the pump needs to be placed on land, suction pipe on the water, but also need to pump start. Mud pump and submerged centrifugal pump due to structural constraints, the work needs to be placed on the water above the motor, the pump into the water, it must be fixed, otherwise, the motor fell into the water will cause the motor scrapped. Moreover, since the length of the major axis is generally constant, it is troublesome to install and use the pump, and the application occasion is subject to many limitations.
