Single stage double suction centrifugal pump

It is a single stage double suction centrifugal pump from both sides of the impeller water, because the pump cover and pump body is assembled by the horizontal joint, also known as the horizontal open centrifugal pump. Compared with single stage single suction centrifugal pump, high efficiency, large flow, higher head. But the volume is large, relatively bulky, generally used for fixed operations. It is suitable for irrigated areas in hills and plateaus, as well as for factories, mines and urban water supply and drainage. Single stage double suction centrifugal pump has several models, such as S type, Sh type, SA type, SLA type. The difference between S type and Sh type is that, from the driving end, S type pump rotates in the clockwise direction, Sh type rotates in the counterclockwise direction. SLA type for vertical single - stage double - suction centrifugal pump.

Single stage single suction centrifugal pump

The old pump models are BA, B type single stage single suction centrifugal pump. In the 1980s, according to the international standards and the actual situation of drainage and irrigation machinery, our country carried out the updating and development of centrifugal pump products, and produced IB type, IQ type single stage centrifugal pump series products, which have been listed as the national professional standards and industry standards. Single stage single suction centrifugal pump, water from the axial side into the impeller, impeller only one, so called single stage single suction centrifugal pump. Its characteristics are, compared with mixed flow pump, axial flow pump, higher head, smaller flow, simple structure, easy to use.

Working principle of mixed flow pump

Because the impeller shape of the mixed flow pump is between the centrifugal pump impeller and the axial flow pump impeller, therefore, the working principle of the mixed flow pump has both centrifugal force and lift, by the combined action of the two, the water is to flow out of the impeller at a certain Angle with the shaft, through the volute chamber and the pipeline to the high water.

Working principle of axial flow pump

Axial flow pump and centrifugal pump working principle is different, it is mainly the use of the impeller's high-speed rotation of the thrust generated by the water. The lift force generated by the rotating blades of the axial-flow pump pushes the water from below to above. The blades of the axial flow pump are generally immersed in the pool of water being sucked. Due to the high-speed rotation of the impeller, under the action of the lift generated by the blade, the water is continuously pushed upward, so that the water flows out along the outlet pipe. The impeller is constantly rotating, and the water is continuously pressed to the top.

General characteristics of centrifugal pump

(1) The flow direction of water along the centrifugal pump is the axial suction along the impeller, perpendicular to the axial flow out, that is, in and out of the direction of the water into 90 degrees. (2) Because the centrifugal pump forms a vacuum suction by the inlet of the impeller, so before starting, it must be injected into the pump and the suction pipe, or pumped with a vacuum pump, in order to discharge the air to form a vacuum, and the pump shell and suction pipe must be strictly sealed, no air leakage, otherwise no vacuum, it will not suck water. (3) Because the inlet of the impeller can not form an absolute vacuum, so the suction height of the centrifugal pump can not exceed 10 meters, and the water through the suction pipe caused by the loss along the actual allowable installation height (the height of the pump axis from the suction water) is far less than 10 meters. If the installation is too high, it will not absorb water; In addition, because the mountain area is lower than the plain atmospheric pressure, so the same pump in the mountain area, especially in the high mountain installation, the installation height should be reduced, otherwise it can not suck water.

Working principle of centrifugal pump

Before the pump starts, the pump and the inlet pipe are filled with water. After the pump runs, under the action of centrifugal force generated by high-speed rotation of the impeller, the water in the impeller runner is thrown around and pressed into the volute. The inlet of the impeller forms a vacuum, and the water in the pool is sucked into the suction pipe under the external atmospheric pressure. Then the suction of the water is thrown out by the impeller through the volute and into the outlet pipe. It can be seen that if the centrifugal pump impeller constantly rotating, it can continuously absorb water, pressure water, water can continuously from low to high or far away. To sum up, the centrifugal pump is due to the centrifugal force produced by the high-speed rotation of the impeller under the action of the water to the height, so called centrifugal pump.
