Hebei vertical slurry pump structure

Slurry pump is powerful, which is related to its structure. Reasonable structure, which is not only convenient for users, but more importantly, reasonable structure. We can understand their structure. Use them to improve efficiency. What is their structure? Let me give you a detailed introduction to its structure and composition. 1. structure of pump head. The pump body of vertical slurry pump adopts double-layer pump casing (inner and outer double-layer metal structure), and the double-layer pump casing structure is vertical and open. Outlet positions can be installed at 45 intervals and rotated in 8 different positions. In order to effectively prevent shaft seal leakage, a combination of dynamic seal, packing seal or mechanical seal is adopted. There is a labyrinth gap seal between the impeller and the rear guard plate, which reduces the leakage of slurry to the stuffing box and effectively ensures the reliability of the seal. The impeller is equipped with a rear blade to discharge the backflow slurry in time, thereby improving the floor area ratio, reducing backflow and scouring and prolonging the service life of the circulation parts. 2. Support structure. The bracket structure is horizontally open. In order to prolong the service life of bearings, the hydraulic design and structural design are optimized. Make radial force and axial force distributed reasonably. 3. Type of shaft seal. The shaft seal device plays a sealing role between the pump body and the pump shaft of the vertical slurry pump. It can prevent air from entering the pump and a large amount of water from leaking out of the pump. The sealing form of centrifugal slurry pump usually adopts auxiliary impeller and packing seal, which is fluid dynamic pressure seal. The pressure head produced by auxiliary impeller resists the leakage of liquid at the outlet of impeller. At the same time, the impeller cover is used to set the rear blade, adding water sealing ring and packing to prevent air from entering. The rear blade and water sealing ring are used to reduce the pressure at the packing and effectively prevent impurities from entering the seal.
