Product Description
Mortar pump is a centrifugal pump specifically designed for transporting liquid-solid mixed media containing solid particles such as sand, slag, mud, etc. It is widely used in fields such as construction, mining, metallurgy, and power. Its working principle is based on the centrifugal force, and the core is to convert mechanical energy into kinetic energy and pressure energy of the slurry through the rotating impeller. The following is its detailed working principle:
Main composition structure
1. Main composition structure
-Pump body: It is usually made of wear-resistant materials (such as high chromium alloys) and designed as a snail shell structure internally to guide the flow of slurry.
-Impeller: Open or closed impeller with few and wide blades to reduce blockage; The material is wear-resistant and corrosion-resistant.
-Shaft and bearings: supporting the rotation of the impeller, they need to withstand high loads and vibrations.
-Sealing system: mechanical seal or packing seal to prevent slurry leakage.
Drive device: Electric motor or diesel engine, providing power.
Working principle steps
1. Start up and impeller rotation
The motor-driven pump shaft drives the impeller to rotate at high speed (usually several hundred to several thousand revolutions per minute).
2. Centrifugal force generation
When the impeller rotates, the blades do work on the slurry, and the slurry is thrown towards the outer edge of the impeller under centrifugal force, forming high-speed flow.
3. Inhalation and excretion process
Formation of low pressure zone: The center of the impeller forms a low pressure zone due to the slurry being thrown out, and the slurry at the pump inlet is sucked into the pump under atmospheric pressure.
Conversion of kinetic energy into pressure energy: The high-speed flowing slurry enters the volute shaped pump body, the flow channel gradually expands, the flow velocity decreases, and some kinetic energy is converted into pressure energy, which is finally discharged at high pressure from the outlet.
4. Continuous conveying
The impeller continues to rotate, and the suction and discharge processes circulate to achieve continuous transportation of the slurry.
Key design features
Wear resistance: The impeller and pump liner are made of high hardness materials (such as rubber, ceramics, alloys) to resist the wear of solid particles.
Anti clogging design: wide channel, few blade impeller, allowing larger particles to pass through (such as sand, gravel, slag).
Sealing protection: Mechanical seals are supplemented with flushing water or secondary impellers to prevent particles from entering the sealing surface and causing failure.
Power matching: The motor power needs to adapt to the transportation requirements of high-density and high viscosity slurry.
Application scenarios
Construction site: Transport concrete mortar and cement slurry.
Mining beneficiation: transporting slurry and tailings.
Dredging project: dredging of river channels and transportation of sediment.
Thermal power generation: transportation of ash and coal slurry.
precautions
Avoid dry running: When running without a medium, friction can cause rapid wear of components.
Particle control: The transported particles must meet the rated particle size and concentration requirements of the pump.
Regular maintenance: Check the wear of impellers and seals and replace them in a timely manner.
summarize
The mortar pump achieves the suction and pressurized discharge of slurry through the centrifugal force generated by the rotation of the impeller. Its wear-resistant and anti blocking design makes it suitable for high wear and high solid content working conditions. Understanding its principles helps optimize selection, operation, and maintenance, and extend equipment lifespan.
