The water pump parts refer to what, the main water pump parts have what, the water pump parts contain what parts

A, the water pump parts refer to which

A lot of pump products do not understand the personnel very want to know about the main flow components of the pump, in fact, we take the most commonly used centrifugal pump as an example of centrifugal pump belongs to the blade pump, the main flow components of the vane pump impeller, suction chamber, pressure chamber (including radial guide vane and space guide vane) and other main components

Two, the role of the pump impeller and impeller type

Pump impeller is an important part of pump, its shape, size, processing technology and so on have a decisive impact on pump performance. Pump impeller is the role of the prime mover input energy to the liquid. The shape and size of pump impeller are closely related to pump performance. Pump impeller can be divided into two types: single suction and double suction. Single suction impeller for one - side water absorption, small flow pump impeller for this form. Double-suction impeller for both sides of water, large flow pump impeller are double-suction impeller.

There are three main types of pump impeller structure: front and rear cover known as the closed impeller. Only the rear cover plate is called the semi - open impeller. The one without front and rear cover is called the open impeller. In addition, the structure of blades can be divided into cylindrical blades and twisted blades. Centrifugal pump impeller blades are generally back - curved blades. The blades are cylindrical and twisted. The application of twisted blades can reduce the load of the blades, improve the suction capacity of the centrifugal pump and improve the cavitation resistance. However, it is difficult to manufacture and the cost is high. Centrifugal pumps for oil refining and chemical industry require the impeller for casting or full weld welded integral pump impeller. Welding pump impeller is developed in recent years, mostly used for casting poor performance of metal materials, such as iron and its alloys, manufacturing special chemical centrifugal pump. The geometric precision and surface finish of the welding pump impeller are better than that of the casting impeller, which is beneficial to improve the efficiency of the centrifugal pump. General closed water pump impeller has 2-12 backward-curved blades, with high operating efficiency, such as the aforementioned single-suction, double-suction centrifugal pump used this kind of impeller. One of the single-stage single-suction centrifugal pump impeller because of the axial force, so some impeller in the root of the blade open a balance hole.
