Self-priming centrifugal pump centrifugal pump family is an important member of its work in addition to the need to pump before the first start of the pump, other times do not need to do this treatment. It is automatically sucked out of the gas pipe, while the completion of the delivery of liquid centrifugal pump. The following will introduce the working principle of self-priming centrifugal pump. Self-priming centrifugal pump working principle Self-priming centrifugal pump working principle is: self-priming centrifugal pump so that 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 to form a vacuum state, when the impeller rotates quickly, the blade to promote rapid rotation of water, rotating water from the impeller in the centrifugal force to fly, pump water After being thrown, 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 body heat, vibration, reduce the amount of water, causing damage to the pump (referred to as "cavitation ") Equipment accident! Many types of self-priming centrifugal pumps, 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 points: Open-impeller self-priming centrifugal pump semi-open impeller self-priming centrifugal pump closed impeller self-priming centrifugal pump. Press work 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. Self-priming centrifugal pump working principle in self-priming centrifugal pump throughout the work has a very positive role, if the worker can master the self-priming centrifugal pump working principle, I believe the use of self-priming centrifugal pumps and protection Can have a significant impact. Therefore, self-priming centrifugal pump working principle needs attention.
