Product Description
A slurry pump refers to a device that converts electrical energy into kinetic energy and potential energy of the medium by increasing the energy of the solid-liquid mixed medium through the action of centrifugal force (rotation of the impeller of the pump). Mainly applicable to: mines, power plants, dredging, metallurgy, chemicals, building materials and petroleum industries.
The slurry pump transports the mixture of solid particles containing dregs and water. But in principle, the slurry pump is a kind of centrifugal pump, and it is mainly used in iron and steel enterprises to transport mud in converter dedusting water, blast furnace gas washing water, continuous casting turbid ring water and steel rolling turbid ring water.
The commonly used slurry pump structure is as follows.
(1) Pump head structure. The pump body adopts double-layer pump casing (inner and outer double-layer metal structure), and the double-pump casing shell structure is vertically open, and the outlet position can be installed and used in 8 different positions by rotating at intervals of 45°. In order to effectively prevent shaft seal leakage, a combination of dynamic seal, packing seal or mechanical seal is used. There is a labyrinth gap seal between the impeller and the rear guard plate, which greatly reduces the leakage of the slurry to the stuffing box and effectively ensures the reliability of the seal. The impeller is equipped with back blades to discharge the backflow slurry in time, thereby increasing the volume ratio, reducing backflow and erosion, and improving the life of the flow-passing parts. A dismantling ring is provided for easy maintenance and disassembly, which avoids the phenomenon of shaft cutting due to inability to disassemble.
(2) Bracket structure. The bracket structure is a horizontal split type, in order to prolong the service life of the bearing, the hydraulic design and structural design are optimized. The radial force and axial force are distributed reasonably, and the bearing form, model, cooling and lubrication method are correctly selected, so as to meet the requirements of low heat generation and long service life of the bearing.
(3) Shaft seal form. The shaft sealing device acts as a seal between the pump body and the pump shaft. Prevents air from entering the pump and large amounts of water from leaking out of the pump. The sealing form of the centrifugal slurry pump usually adopts the auxiliary impeller plus packing seal. The auxiliary impeller plus packing seal is a hydrodynamic seal. The pressure head generated by the auxiliary impeller resists the leakage of the liquid at the outlet of the impeller. Add water seal ring and packing to prevent air from entering, and use back blade and water seal ring to reduce the pressure at the packing, which can prevent impurities from entering the seal.
