Structure and application characteristics of lightweight slurry pump and heavy-duty slurry pump

(1) Light slurry pump and heavy slurry pump according to the different abrasiveness of the conveying medium, the slurry can generally be divided into strong abrasive slurry and weak abrasive slurry. If the weight concentration of the slurry is C> 20%, solid relative density S> 20, solid particles d> 0.05n boron is a strong abrasive slurry, and other weak abrasive slurry is a weak abrasive slurry. Slurry pumps that transport the above two kinds of slurry are called heavy-duty slurry pumps and light-duty slurry pumps. The conveying medium of coal washing industry belongs to weak abrasive slurry, and the suitable equipment is light slurry pump.

(2) The structural characteristics of light slurry pump and heavy slurry pump The basic structure of heavy slurry pump is double shell, with volute and front and rear pump shell, which belongs to single-stage, single-suction cantilever, horizontal, axial suction radial discharge centrifugal slurry pump. This type of pump has high manufacturing cost and complex maintenance and disassembly.

The basic structure of the lightweight slurry pump is a single shell, only volute, no pump shell, belonging to a single stage, single suction cantilever, horizontal, axial suction radial discharge centrifugal slurry pump. This type of pump has the advantages of simple structure, convenient maintenance and low manufacturing cost.

At present, the heavy-duty slurry pumps developed by CNSME include zJ series slurry pumps, which have been designed and developed and put into production with nearly 100 product specifications, featuring high efficiency, energy saving, high abrasion, reliable operation and long life.
