Characteristics and Advantages of Slurry Pump Under Blockage-free Liquid

Working principle: The slurry pump under the unblocked liquid is usually installed at the bottom of the liquid pool, and the slurry is transported to the inside of the pump body through the inlet pipe. The rotating impeller in the pump rotates at high speed under the drive of the motor, generating centrifugal force, sucking the slurry into the pump and pressurizing it, and finally draining the slurry out of the pump body to complete the conveying task. This design allows the pump to cope with large particles, high concentrations of slurry media, and has strong anti-blocking capabilities.

Structural features:

Impeller design: The impeller is generally a semi-open type impeller, and stirring blades are provided at the extension of the impeller suction edge. This design allows the slurry to stir and crush large particulate matter that may be blocked while sucking in, allowing it to pass through the pump body smoothly.

Shaft support: The pump shaft at the lower part of the liquid has sufficient stiffness to ensure that it can withstand a large load and impact force during the conveying of slurry.

Sealing method: Use impeller plus filler combined seal or mechanical seal to ensure that there is no leakage during operation of the slurry pump.

Bearing setting: No bearing is installed between the impeller and the pump housing, which reduces faults caused by bearing wear and also reduces the maintenance cost of the pump.

Performance Advantages:

Good anti-blocking performance: the runner is wide and can effectively transport slurry containing larger particles, which is not prone to blockage, ensuring the stable operation of the pump.

Strong wear and corrosion resistance: Overcurrent components are made of special materials, such as high chromium alloys, which have good wear and corrosion resistance and can run for a long time in harsh working environments.

Application areas:

Environmental protection industry: used in urban sewage treatment plants, industrial wastewater treatment and other places to transport sewage containing impurities such as sludge and waste slag.

Mining field: During the mining process, medium containing a large amount of solid particles is transported, such as slurry and tailings.

Power industry: used for ash slag transport, desulfurization systems, etc. in thermal power plants.

Construction industry: It can be used for drainage, mud transport, etc. at construction sites.

Maintenance:

Regularly check the wear of the pump impeller, pump body and other components, and replace the seriously worn parts in a timely manner.

Keep the pump lubricated well and add or replace lubricant regularly.

Check the sealing performance of the pump and deal with it in time if there is any leakage.

When the pump stops operating for a long time, the pump should be removed, wiped clean, and coated with anti-rust oil to store properly.
