A wide range of centrifugal pumps, selected according to need

According to the number of working impeller to classify 1, single-stage pump: that is, only one impeller on the shaft. 2, multi-stage pump: that is, there are two or more impellers on the pump shaft, then the total pump head is the sum of the lift produced by n impellers. According to the working pressure to classify 1, low pressure pump: the pressure is lower than 100 meters of water column; 2, medium pressure pump: the pressure is between 100 ~ 650 meters of water column; 3, high pressure pump: pressure is higher than 650 meters of water column. According to the impeller water classification 1, one side into the water pump: also known as single suction pump, that is, only one inlet on the impeller; 2, bilateral water pump: also known as double suction pump, that is, both sides of the impeller There is a water inlet. Its flow rate is double that of a single suction pump, which can be approximated as two single-suction pump impellers placed back-to-back together. According to the combination of the pump casing to form a classification of 1, the level of open pump: that is, through the axis of the horizontal plane with a joint seam. 2, the vertical joint pump: that is, the junction plane and the axis of the vertical. Classified according to the pump shaft position 1, horizontal pump: the pump shaft is in a horizontal position. 2, vertical pump: pump shaft is located in the vertical position. Press the impeller out of the water leads to the pressure chamber classification 1, volute pump: water from the impeller, directly into the shape of the pump shell with a spiral. 2, guide vane pump: water from the impeller out into the guide vane set outside it, and then into the next level or into the outlet pipe. Centrifugal pump installation height and working classification 1, self-filling centrifugal pump: pump shaft below the sump pool surface, start without irrigation, can be automatically activated. 2, suction centrifugal pump (non-self-filling centrifugal pump): pump shaft above the sump pool surface. Before starting, it is necessary to fill the pump housing and the suction pipe with water first, and then drive the motor so that the impeller rotates at a high speed. The water is thrown out of the impeller by the centrifugal force, a negative pressure is formed in the center of the impeller, the water in the suction tank enters the impeller under the action of atmospheric pressure, Also by the high-speed rotation of the impeller role was thrown into the water pressure impeller. 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 Times the number of single-stage pump shaft only one impeller multi-stage pump 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 the head according to the pump shaft orientation horizontal Horizontal shaft pump shaft placed perpendicular to the horizontal plane according to the shell type Split pump shell according to the vertical plane with the shaft part of the segment with a long bolt connection between the open pump housing through the shaft center Divided volute casing in line plane Centrifugal pump with spiral pressure chamber, eg common end-suction cantilever centrifugal pump Turbine pump Centrifugal pump with guide vane pressurized water chamber Pipe with special structure Pump as Pipeline part of the installation without the need to change the pipe shield Pump impeller and motor rotor together, and in the same sealed shell, without the use of sealing structure, are non-leakage pump Magnetic pump in addition to import and export, the pump fully enclosed Pumps and electricity The machine uses magnets to attract each other and drives the self-priming pump. No need for high-speed pump to start the pump. The speed of the pump shaft is increased by the speed increasing box. The general speed can reach over 10000r / min. It can also be called partial flow pump or tangent increase Pump vertical tube pump import and export takeover in the upper part of the same height, there are two inner and outer shell, the inner shell by the rotor, guide vanes and other components, the outer shell for the import diversion channel, the liquid inhalation from the bottom.
