Self-priming centrifugal pump works
Self-priming centrifugal pumps work principle is: self-priming centrifugal pump so water can be sent out due to the role of centrifugal force. Pump before work, the pump body and the inlet pipe must be filled with water into a vacuum state, when the impeller is rapidly rotating, the blade to promote rapid rotation of water, rotating water from the impeller in the centrifugal force of the fly, the pump After the water is thrown out, the central part of the impeller forms a vacuum area. Suwon's water pressure in the air pressure (or water pressure) under pressure through the pipe into the water pipe. This endless cycle, you can achieve continuous pumping. It is worth mentioning that: self-priming centrifugal pump must be started before the pump casing filled with water before starting, otherwise it will cause the pump heat, vibration, reduce the amount of water, causing damage to the pump (referred to as "gas Eclipse ") Equipment accident! Many types of self-priming centrifugal pump, classification methods are common in the following ways: 1 by the impeller inhalation points: single-suction self-priming centrifugal pump double-suction self-priming centrifugal pump. 2 according to the number of impeller points: single-stage self-priming centrifugal pump multi-stage self-priming centrifugal pump. 3 according to the structure of the impeller: open impeller self-priming centrifugal pump semi-open impeller self-priming centrifugal pump closed impeller self-priming centrifugal pump. 4 according to the working pressure points: Low-pressure self-priming centrifugal pump Medium-pressure self-priming centrifugal pump High-pressure self-priming centrifugal pump Side vertical self-priming centrifugal pump.
