Today, I saw that some customers came to the company's website www.cnsmepump.com through centrifugal slurry pumps. I must have a lot of doubts in my heart. What is the difference between centrifugal slurry pumps and slurry pumps?

     In fact, in principle, the slurry pump belongs to a centrifugal pump. Because the working principle of the slurry pump is to use the centrifugal force of the impeller to achieve the conveying of the slurry.

      Most centrifugal pumps are mainly used to transport media with physical properties similar to water, that is, no particles, or particles are very small.

The main working parts of the centrifugal pump are the impeller and the pump housing, the impeller is mounted on the shaft, and is connected with the motor or other prime movers to form a whole. When the motor drives the impeller to rotate, the blade in the impeller forces the slurry to rotate, that is, the blade of the impeller does work on the slurry along its direction of movement, thus forcing the potential energy and kinetic energy of the slurry to increase. At the same time, the slurry under the action of inertial force, flows from the center to the periphery of the impeller, and flows out at a very high speed, this process is the pressure water process. The centrifugal pump relies on the action of the rotating impeller on the liquid to transfer the mechanical energy of the prime mover to the liquid.

     Due to the role of the centrifugal pump liquid flow from the impeller inlet to the outlet process, the speed and pressure energy are increased, the liquid discharged by the impeller through the pressure chamber, most of the speed can be converted into pressure energy, and then transported out along the discharge pipeline, at this time, the inlet of the impeller due to the discharge of liquid to form a vacuum or low pressure, The liquid in the suction pool is pressed into the inlet of the impeller under the action of the liquid surface pressure (atmospheric pressure), so the rotating impeller continuously inhales and exhautes the liquid. In fact, the slurry pump is also through the centrifugal force formed by the impeller rotation to transport the slurry. So the slurry pump is also a centrifugal pump. In this way, the relationship between the slurry pump and the centrifugal pump will be clear.

     The reason why the slurry pump is called the slurry pump is defined from the conveying medium. As the name suggests, the slurry transported by the slurry pump is a mixture of solid particles containing slag and water.

CNSME is a professional slurry pump manufacturer and supplier offering all types of slurry pumps. Every time the customer sees the production and assembly of the slurry pump, today we look at how the slurry pump is installed.

First, raw material procurement

The first step in slurry pump production is raw material procurement. The choice of raw materials in the pump industry is wide, and the common materials are cast iron, stainless steel, plastic and so on. In the procurement process, we need to strictly control the quality of raw materials to ensure that they meet production standards and quality requirements.

Second, processing and manufacturing

After the procurement of raw materials is completed, it enters the processing and manufacturing link. The production of pumps needs to be manufactured and processed according to different models and specifications. Among them, the processing content includes forging, stamping, casting, welding and so on. In the process of processing and manufacturing, it is necessary to be equipped with appropriate equipment and technical personnel to ensure product quality and production efficiency.

Third, test the quality

The finished pump needs to be quality tested to ensure that the product quality meets the design and standard requirements. The test of the pump includes static water leakage test, water pressure test, noise test and other links to ensure that the performance and quality of the pump meet the standard.

Fourth, assembly and packaging

Slurry pump production to this stage must be assembled and packaged. In this link, different types of pumps need to be distributed and assembled, and packaged in strict accordance with packaging standards. Pump packaging needs to adopt standard materials and methods to ensure the safety and integrity of the product.

Five. Delivery from warehouse

After the production of the pump is complete, the final delivery process can be carried out. In this link, it is necessary to deliver goods out of the warehouse in strict accordance with the order requirements, and track the product transportation process to ensure the safe delivery of products to customers.

Six. After-sales service

The after-sales service of the slurry pump is also a very important part of the entire production process. In the after-sales service, it is necessary to deal with the problems of customer feedback in a timely manner, and provide professional technical support and services to ensure the effective use of products and improve customer satisfaction. 【 Conclusion 】 This paper gives a comprehensive and systematic introduction to the production process of slurry pump, including raw material procurement, processing and manufacturing, quality testing, assembly and packaging, delivery and after-sales service. Only in each link to achieve strict control, in order to produce high-quality pump products.

The sheath is also called the volute, because its shape is more like the shell of a snail. It's made of the same material as the impeller and there are many different materials. We determine the material to use according to the characteristics of the slurry.

Cast iron material: not wear-resistant, cheap.

High chromium alloy: wear resistance, corrosion resistance, in the slurry pump used more.

Natural rubber: wear-resistant, corrosion-resistant, generally conveying non-angular particles of the slurry used more, compared with high chromium alloy will be a little corrosion resistance.

A49 material: This material price is relatively high, generally used to transport more corrosive slurry. In the desulfurization pump used more.

The above are several materials commonly used in slurry pumps. In addition, 316 stainless steel, lined with ceramic material. These several are used less, generally for special grout will choose these two materials, and the price will be much higher than the other several.
