Inhalation centrifugal pump (non-self-filling centrifugal pump) working principle and structure

[Asia Fluid Network News] Suction centrifugal pump, also known as non-self-filling centrifugal pump, the pump shaft work is higher than the sump pool surface. The face of fierce competition in the current product market, suction-type centrifugal pump is also facing the cruel reality, if you want its future development has a better future, manufacturers need to do is still much; for customers, the election Buy products, use the product first need to understand the working principle of the product. Inhalation centrifugal pump (non-self-filling centrifugal pump) working principle and structure diagram Next, the centrifugal pump will be introduced in detail the working principle: Before starting, you need to fill the pump casing and water pipes, and then drive the motor, so that the impeller Centrifugal force is thrown by the water centrifugal impeller, the impeller center to form a negative pressure, water in the pool under atmospheric pressure into the impeller, but also by the high-speed rotation of the impeller, was thrown out of the impeller into the water pipe. Usually we say that a pump is a multistage pump, which means how much the impeller. According to other structural features, it may be horizontal pump, vertical joint surface pumps, vane pumps, high pressure pumps, single-inlet pumps and so on. So according to different, the name is not the same. In addition, according to the use can also be classified, such as pumps, pumps, condensate pumps, ash pumps, circulating pumps and so on. Classification Type Centrifugal Pump Features By suction Single suction pump Liquid flows into the impeller from one side, with axial force Double suction pump The liquid flows into the impeller from both sides, there is no axial force, the flow of the pump is almost one more than the single suction pump Multiply according to the number of single-stage pump shaft only one impeller multi-stage pump on the same pump shaft mounted on two or more impeller, the liquid flow through each stage of the impeller, the more the series, the higher head lift, according to the shaft orientation The pump shaft is placed horizontally. Vertical pump shaft perpendicular to the horizontal plane according to the type of shell Split pump shell according to the vertical plane with the shaft section and the segment with a long bolt between the open pump housing in the plane through the axis of the axis Split volute pump Centrifugal pump equipped with a spiral pressure chamber, such as the commonly used end-suction cantilever centrifugal pump, turbine pump with a guide vane pressure chamber centrifugal pump special structure pump as part of the pipeline , The installation without changing the submersible pump and motor pump made of integrated immersion in water submerged pump immersed in liquid pump impeller and motor rotor together as a whole, and in the same sealed shell, without the use of sealing structure, which is not Leakage pump Magnetic pump in addition to the import and export, the pump body is fully closed, the pump and the motor magnetically attract each other and drive self-priming pump pump start without the need for high-speed pumping fluid from the gear box to increase the speed of the shaft, the general Speed ​​up to 10000r / min or more, can also be said that part of the pump or tangential booster pump inlet and outlet vertical tube pump take over the same height in the upper, inner and outer two shells, the inner shell by the rotor, guide vane And other components, the outer shell for the import diversion Road, the liquid inhalation from the bottom. Summarized, through the analysis of the working principle of the centrifugal pump, we can understand that the working principle of the centrifugal pump is mainly through high-speed rotation of the impeller, the water is thrown by centrifugal force impeller, the impeller center to form a negative pressure, water absorption The pool of water into the impeller at atmospheric pressure, but also by the role of high-speed rotation of the impeller, thrown out of the impeller into the pressurized water pipe. The main factor depends on the impeller. Inhalation centrifugal pump long-term healthy and stable development, or long way to go.
