Interpretation of the structure of multi-stage slurry pump, multi-stage slurry pump classification

Compared with a single-stage slurry pump, multi-stage slurry pump has a more complex structure, function is more powerful, the application of the operating environment is more complex. Today, Xiao Bian to share the structure and classification of multi-stage slurry pump knowledge, I hope you will like! Interpretation of the structure of multi-stage slurry pump, multi-stage slurry pump classification (A) multi-stage slurry pump structure and more Slurry pump mainly by the stator, rotor, bearing and shaft seal composed of four parts: 1, multi-stage slurry pump stator part mainly by the suction section, the middle section, vomiting section and guide vanes and other components, Clamp to form a studio. D-type pump generally horizontal inhalation, vertical spit up; for the injection of oil, the pump import and export are up vertically. DG-type multi-stage slurry pump out, the entrance are up vertically. 2, multi-stage slurry pump rotor mainly by the shaft, impeller, balance disc and sleeve and other components. The axial force is balanced by the balance disc. 3, multi-stage slurry pump bearings mainly by the bearing body, bearing and bearing gland and other components, bearing grease or thin oil lubrication. 4, multi-stage slurry pump shaft seal with soft packing seal, mainly by the inlet section and tail cover on the letter, packing, retaining ring and other components. D-pump water seal water from the pump pressure water. DG pump water seal water from the external water supply. 5, multi-stage slurry pump rotary pump through the elastic coupling directly driven by the prime mover. From the original motivation to see the pump, the pump rotates clockwise D, DG-type pump is a horizontal single-suction multi-stage segmented centrifugal pump. For the transport of water (containing less than 1% impurity, particle size less than 0.1mm) or other physical and chemical properties similar to water. D-type pump medium temperature less than 80 ℃, suitable for mine drainage, oilfield water, factories and cities to the drainage and other occasions. Oilfield water injection pump according to the corrosive nature of the pump using different materials. DG-type pump medium temperature less than 105 ℃, suitable for a variety of boiler feed water. (B) classification of multi-stage slurry pump 1, from the pump shaft and horizontal position of the division: horizontal slurry pump and vertical slurry pump 2, the way from the impeller into the water: single-suction slurry pump and double suction Slurry pump 3, from the pump shell structure: the level of open and vertical combination (Editor: Huang Nengwen QQ :)
