Introduction

ZJ heavy duty slurry pump applied in abrasive liquids. It is used to transport liquids with solid particles, such as ore, lime, coal, sand, quartz, etc. Or high concentration mud.

ZJ heavy duty slurry pump body

The pump body adopts double-layer pump shell (inner and outer double-layer metal structure). The shell structure of double pump shell is vertical open type. The water outlet can be installed at 8 different positions at 45 ° intervals. In order to effectively prevent shaft seal leakage, the combination of power seal, packing seal or mechanical seal is adopted. The labyrinth gap seal is set between the impeller and the rear guard plate, which greatly reduces the leakage of slurry to the stuffing box and effectively ensures the reliability of the seal. The impeller is equipped with back blades to discharge the reflux slurry in time, so as to improve the volume ratio, reduce the reflux and erosion, and improve the service life of the overflow parts. In order to facilitate maintenance and disassembly, a disassembly ring is set to avoid shaft cutting due to non disassembly.

ZJ heavy duty slurry pump bracket

The bracket structure is 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 reasonably distributed, and the bearing form, model, cooling and lubrication mode are correctly selected, so as to meet the requirements of low heating and high service life of the bearing.

ZJ heavy duty slurry pump shaft seal

The shaft sealing device plays a sealing role between the pump body and the pump shaft. It can prevent air from invading the pump and a large amount of water from leaking out of the pump. The sealing form of centrifugal slurry pump usually adopts the auxiliary impeller and packing seal. The auxiliary impeller and packing seal is a hydrodynamic seal. The pressure head generated by the auxiliary impeller resists the external leakage of liquid at the impeller outlet. At the same time, the impeller cover plate is used to set the back blade and water sealing ring and packing to prevent air from entering, and the back blade and water sealing ring are used to reduce the pressure at the packing, It can prevent impurities from entering the seal.
