Centrifugal Pump Impeller Details
A centrifugal pump is often thought of as a kinetic energy machine. The rotation of the impeller spins the fluid in the impeller at a high speed, thereby transferring energy to the liquid.
Centrifugal pump impeller mainly has the following four forms:
1. Closed impeller
Composed of blades and front and rear cover plates, the closed impeller has high efficiency and is difficult to manufacture, so it is widely used in centrifugal pumps. It is suitable for conveying clear water, solutions and other clean liquids with low viscosity and no particles.
2. Semi-open impeller
Generally, there are two structures. One is the front half-open type, which is composed of the rear cover plate and the blades. The impeller efficiency of this structure is low. In order to improve the impeller, a sealing ring with adjustable clearance is required.
The other is the rear semi-open type, which is composed of the front cover plate and the blades. Since the same sealing ring as the closed impeller can be applied, the efficiency is basically the same as that of the closed impeller, and the blades also have back blades or auxiliary blades in addition to conveying liquid. The sealing effect of the impeller. The semi-open impeller is suitable for transporting liquids containing suspended solids such as solid particles and fibers. The semi-open impeller is less difficult to manufacture, lower in cost, and has strong adaptability. The application of centrifugal pumps in refining and chemical industry is gradually increasing, and it is used to transport clear water and liquids similar to clear water.
3. Open impeller
There are only blades and blade ribs, and no front and rear cover impellers (the number of blades of open impellers is less than 2~5). The impeller has low efficiency and is rarely used. It is mainly used to transport liquids with high viscosity and award-winning liquids.
The blades of centrifugal pump impellers are generally backward curved blades. There are two types of blades: cylindrical and twisted. The application of twisted blades can reduce the load on the blades, and can improve the suction performance of the centrifugal pump and improve the cavitation resistance, but the manufacturing Difficulty is big, and cost is higher.
Centrifugal pumps for oil refinery and chemical industry require the impeller to be a cast or fully welded integral impeller. Welded impellers are developed and are mostly used in chemical special centrifugal pumps made of metal materials with poor casting performance (such as iron and its alloys). The geometric accuracy and surface finish of welded impellers are better than cast impellers, which is beneficial to improve the efficiency of centrifugal pumps.
