The basic structure of slurry pump consists of impeller, pump shell, shaft, bearing, bracket and shaft seal. Power is generally connected to the motor, which can be directly connected through the coupling or connected through the belt and pulley.
The principle is that when the impeller runs rapidly, the blades of the impeller promote the slurry to rotate rapidly, and the rotating slurry flies out of the impeller under the action of centrifugal force. After the liquid in the pump cavity is thrown out, a vacuum zone is formed in the center of the impeller, and the slurry is pressed into the feed pipe through the pipe network under the action of atmospheric pressure or water pressure, so as to realize continuous feeding and achieve the lift and flow required by the design working condition. At present, the feeding mode of slurry pump is mostly backward-flow installation, that is, the slurry level is higher than the inlet of the pump.
The above is an introduction to what kind of pump the slurry pump is and how it works. I hope I can help you. There is a lot of related knowledge on the home page. Welcome to click to view.
What kind of pump is the slurry pump?
Slurry pump is a large centrifugal pump, whose main task is to transport media containing abrasive solid particles. It is an indispensable general equipment in metallurgy, power plant, mining, coal and other industries.
In principle, slurry pump is a kind of centrifugal pump, which relies on the centrifugal force generated by slurry driven by the rotation of impeller in the pump body to increase its energy and transport it.

Knowledge point 1. Advantages of micro gear oil pump
1, long motor life: stronger sealing, details showing quality, long service life and high efficiency;
2. All-copper coil: 800# cold-rolled silicon steel sheet with low temperature rise, high efficiency, sufficient power and long service life;
3. Stainless steel shaft: the processing and molding run stably, and the surface is treated with moisture and rust prevention;
4. Ball bearing: heavy load bearing, simple structure, convenient use and good dustproof performance;
5, custom alloy seal: 304 stainless steel spring, high strength, small seal, small resistance, sand prevention;
6. High-quality gear: High-temperature quenching improves the hardness and strength of the alloy and is durable.
Knowledge point 2. Where is the screw pump mainly used?
1, Screw pump is widely used for conveying water, wet sludge and flocculant liquid medicine in sewage treatment plants because of its large conveying variable, strong self-priming ability, reversibility and the ability to convey liquid containing solid particles.
2. Because of its structure and working characteristics, the screw pump can transport medium with high solid content, with uniform flow and stable pressure, especially at low speed. Because of its good variable adjustability, it can be used for many purposes and conveying media with different viscosities.
3. The installation position of the screw pump can be tilted at will, which is suitable for conveying sensitive items and items easily damaged by centrifugal force.
Knowledge point three. Working characteristics of screw pump
Screw pump mainly has the following characteristics: simple structure, safe and reliable use, convenient use and maintenance, continuous and uniform liquid discharge, stable pressure, low noise and vibration, and self-priming ability, but screw processing is more troublesome.
Knowledge point 4. What is three screw pump?
Screw pump is a rotary positive displacement pump, which can be divided into single screw pump, double screw pump, three screw pump and multi-screw pump according to the number of screws. Three screw pump is a screw pump with three screws, which includes a driving screw inserted in the pump barrel, two driven screws engaged with it and three mutually engaged screws. They form a sealed cavity in the pump barrel according to their respective leads, resulting in the seal between the suction port and the discharge port.
Knowledge point 5. What are the uses of peristaltic pump?
Any use scenario of peristaltic pump is to treat fluid (any liquid or solid-liquid mixture with fluidity), and the main function of peristaltic pump is to transport. The conveying accuracy of peristaltic pump can reach up to 0.5%, which can meet the needs of quantitative conveying and quantitative distribution.
From the product function, the main uses of peristaltic pump are: quantitative or metered transportation, quantitative or metered distribution. Therefore, peristaltic pump can be used to meet the application requirements in all application scenarios with quantitative transportation and distribution requirements.
Peristaltic pump has excellent performance and reliability, so it is widely used to meet the application requirements of various processes, including experimental research, analytical instruments and industrial production. Therefore, peristaltic pumps have many uses and uses, mainly in the following fields:
1. Analytical instruments: chromatograph, atomic fluorescence photometer.
2. Medical industry: medical equipment and diagnostic reagents.
3. biopharmaceuticals: coating machine, granulator, fermentor, used for purification, fluid transportation, distribution and filling, and high-precision liquid preparation.
4. Laboratory and research equipment.
5. Food and beverage: beverage machine, yogurt machine, vending machine, intelligent milk tea machine, condiment distribution and addition, beer industry.
