The centrifugal pump is composed of many parts. According to the working state of each component at work, it can be roughly divided into three categories
Type: rotating part, fixed part J4: and transfer part. Take the single-stage single-suction horizontal diaphragm pump as an example below, as shown in Figure 2.4.
…The role, composition, structure and material of each part.
2.2.1 Rotating parts
1 Impeller (also known as working wheel)
The call wheel is the main part of the water pump, or even the core part of the water pump. The centrifugal system relies on the high-speed rotation of the impeller
Switch to water to achieve energy transfer.
The wheel-glue of the gear pump is composed of two circular cover plates. Between the cover plates, if there is a 1: a curved blade, the two
The cover plates are connected together, and the space groove enclosed by two adjacent blades and the front and rear cover plates is called the flow of water.
The shape and size of the impeller are determined through experiments and calculations, and can generally be divided into leather suction impeller and double suction impeller.
There is a round hole on the front cover of the impeller called single suction impeller, and the front and rear cover of the impeller have round 7L water inlet.
