The structure of a slurry pump?

2025-05-21

Many people still don't understand the basic information about slurry pumps. Therefore, as a manufacturer, we need to briefly explain that this type of pump is ubiquitous. Its unique structure plays a very important role in the industrial field. Therefore, we need to understand its principle and structure in order to become more familiar with and use it more quickly during operation.

Slurry pumps transport a mixture of solid particles containing slag and water. However, in principle, a slurry pump is a type of centrifugal pump, mainly used in steel enterprises to transport slurry in converter dust removal water, blast furnace gas scrubbing water, continuous casting circulating water, and rolling mill circulating water.

The common structure of a slurry pump is as follows: Pump head structure. The pump body adopts a double-layer pump casing (inner and outer double-layer metal structure). The pump casing structure of the double-layer slurry pump is vertically opened, and the outlet position can be rotated at intervals 8 different positions for installation and use. 45° . To effectively prevent shaft seal leakage, a combination of dynamic seal, packing seal, or mechanical seal is used. A labyrinth gap seal is used between the impeller and the rear guard plate, greatly reducing the leakage of slurry into the stuffing box and effectively ensuring the reliability of the seal. The impeller is equipped with back vanes to promptly discharge the backflow slurry, thereby increasing the volume ratio, reducing backflow and erosion, and improving the service life of the flow components. A disassembly ring is provided for easy maintenance and disassembly, avoiding shaft cutting due to inability to disassemble.

The slurry pump's bracket structure is horizontally split. To extend the bearing service life, the hydraulic design and structural design have been optimized. The radial and axial forces are reasonably distributed, and the bearing type, model, cooling, and lubrication methods are correctly selected to meet the requirements of low bearing heat generation and long service life.

The shaft seal type of the slurry pump mainly refers to the sealing function of the shaft seal device between the pump body and the pump shaft. It prevents air from entering the pump and a large amount of water from leaking from the pump. The sealing type of the centrifugal slurry pump usually adopts an auxiliary impeller plus packing seal. The auxiliary impeller plus packing seal is a dynamic pressure seal. The pressure head generated by the auxiliary impeller resists the leakage of liquid at the impeller outlet. Adding a water seal ring and packing prevents air from entering, and using back vanes and a water seal ring reduces the pressure at the packing, which can prevent impurities from entering the seal.

Our company's products can also meet these advantages. And we have done a very good job in this aspect. . You don't have to worry at all. If you have time, you can visit the official website. There is contact information on the website, and there are online staff to assist you. You can ask them any questions you don't understand. The above article introduces the key points about slurry pumps that you need to know. Friends can read it carefully.
