Will be demolished vertical pipe centrifugal pump classification

【Centrifugal Pump News】 So the demolition of vertical pipe centrifugal pump used at home and abroad the best self-balancing axial force and radial force of the hydraulic model, stable performance, high efficiency, compact structure, small vibration, pump resistance High pressure, easy installation and maintenance. The scope of application is very wide, the corresponding types are also many and varied, the following is a summary of the small series of demolition vertical pipe centrifugal pump several categories, hoping to help everyone. Disassembled vertical pipe centrifugal pump components are: suction chamber, impeller, pressure chamber three parts. The impeller chamber is the heart of the pump and the heart of the flow component. Pump through the impeller on the liquid work, to increase its energy. Impeller classification XBD-ISG Fire Centrifugal Pump impeller according to the direction of the liquid out of the three categories: (1) radial impeller (centrifugal impeller) Liquid is along the axis of the vertical direction out of the impeller. (2) Diagonal impeller (Francis impeller) The liquid flows out of the impeller in a direction inclined to the axis. (3) Axial impeller The direction of liquid flow parallel to the axis. Impeller by inhalation is divided into two categories: (1) single-suction impeller (ie impeller from the side of the inhalation of liquid). (2) double suction impeller (ie impeller suction fluid from both sides). Impeller by cover form is divided into three categories: (1) closed impeller. (2) open impeller. (3) Semi-open impeller. One closed impeller is widely used, the aforementioned single suction impeller double suction impeller belongs to this form. Centrifugal pump type A, according to the number of impeller classification Single-stage centrifugal pump 1, single-stage pump: that is, only one impeller on the pump 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. Second, according to the classification of working pressure 1, low-pressure pump: pressure less than 100 meters of water column; 2, medium-pressure pump: pressure in the range of 100-650 meters of water; 3, high pressure pump: pressure higher than 650 meters of water column. Third, according to the classification of impeller inhalation 1, one side of the water pump: also known as single suction pump, that is, only one inlet on the impeller; 2, double inlet 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. Fourth, according to the pump shell to classify 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. Fifth, according to the pump shaft position to classify 1, horizontal pump: pump shaft is located in horizontal position. 2, vertical pump: pump shaft is located in the vertical position. Six, according to the classification of the impeller 1, volute pump: water from the impeller, directly into the helical shape of the pump housing. 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. Seven, according to the installation of a high degree of 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. In addition, according to the use can also be classified, such as pumps, pumps, condensate pumps, ash pumps, circulating pumps and so on. The above is the impeller according to the liquid out of the direction, according to the impeller inhalation, according to the cover plate impeller, according to the number of impeller, according to the working pressure, according to the impeller inhalation, according to pump shell combination, according to the pump shaft position, according to impeller way Can be divided into different categories.
