What are the main parts of slurry pump?

Slurry Pump Parts are an indispensable part of the slurry pump components

The most important parts of the slurry pump are the four overflow parts, namely the impeller, the front guard, the rear guard, and the sheath.

In addition, shaft seals and transmission parts are also extremely important.

1. Slurry Pump Parts----impeller:

The function of the impeller is to directly transfer the mechanical energy of the prime mover to the liquid to improve the static and dynamic pressure energy of the liquid.

The material is wear-resistant and corrosion-resistant high-chromium alloy (A05, A07, A33, A49), and there are also rubber impellers

According to the mechanical structure, the impeller of the slurry pump mainly has the following forms: closed type, semi-closed type, open type

According to its suction method, it can be divided into single suction type and double suction type

2. Slurry Pump Parts----sheath:

The sheath is also called a volute because its shape resembles a snail.

The material can be high chromium metal alloy material (A05, A07, A33, A49) and rubber

The slurry pump sheath is divided into two types according to the structure:

The sheath of the single-shell pump is generally directly exposed without other pump casing protection. The sheath itself has reserved fastening devices, such as: vertical slurry pump, submerged slurry pump, gravel pump, etc.

The double-shell pump sheath is generally protected by a pump shell on the outside, and its fixation mainly depends on the pressure of the outer pump shell, such as: ZGB type slurry pump, ZJ type slurry pump, fractional pump, etc.

3. Slurry Pump Parts----guard plate:

The main function of the guard plate is to cooperate with the sheath to form a semi-closed flow channel

Make the slurry run in this space

Guards are divided into front guards and rear guards

The front guard plate of the slurry pump is connected to the water inlet pipe

The pump shaft is connected to the impeller through the rear guard plate

4. Slurry Pump Parts----shaft seal:

The slurry pump shaft seal is a sealing device set up to prevent leakage between the pump shaft and the casing.

There are three types of shaft seals: packing seal, auxiliary impeller seal and mechanical seal.

The packing seal has good heat resistance, corrosion resistance and high elasticity

The auxiliary impeller has reliable sealing performance, low price, convenient maintenance, and is suitable for conveying media containing more particles.

The mechanical seal has less leakage, reliable operation, long service life and wide application

5. Slurry Pump Parts----transmission part

The transmission part of the slurry pump is mainly composed of bearings and bearing housings.

Bearing lubrication can use dry oil or thin oil lubrication

Generally, when the temperature of the conveyed material is too high or the scale of the slurry pump is large, the slurry pump is usually lubricated with thin oil.
