(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.

Submersible slurry pump structure

Submersible slurry pump structure

Submersible slurry pumps are widely used in power, metallurgy, coal, mining, environmental protection and other industries.

Bellow we will talk about the structure of submersible slurry pump

The submersible slurry pump is kind of submersible pump, which pump and shaft are coaxial.

When working, the motor drives the pump impeller through the shaft to transfer energy to the slurry medium to generate a certain flow rate, which drives the solid material to flow and realize the slurry transportation.

The submersible slurry pump motor shaft seal is mechanical seal. It can prevent high pressure water and impurities from entering the motor cavity.

In addition to the main impeller, it can also install a stirring impeller, which can extract the slag deposited on the bottom of the water into a turbulent flow and extract it.

The main flow parts such as impeller and stirring impeller are made of high wear-resistant material, which is resistant to abrasion, corrosion, clogging and strong discharge.

As its slurry pump, it can effectively pass large solid particles.
