The following safety information related to slurry pump operation and maintenance should be carefully followed and proper procedures followed to avoid personal injury and equipment damage. All statutory requirements related to this equipment must be complied with at all times.

Do not apply heat to the impeller hub or air intake to aid in impeller removal. Heating may cause impeller crushing, injury or equipment damage.

Do not run the pump at zero or very low flow for extended periods of time. Failure to follow this warning may result in overheating of the pump and evaporation of the pumped fluid, creating very high pressures. Such actions could result in serious personal injury or equipment damage.

Check drive motor rotation before installing drive belts or couplings. Incorrect motor rotation may result in personal injury or equipment damage.

Do not put very hot or very cold fluid into the pump at ambient temperature. Thermal shock can cause the wet end parts of the pump to break. Pumps must be considered rotating machinery and pressure vessels. All relevant safety precautions and procedures for this type of equipment should be followed during installation, operation and maintenance of the pump.

In the case of auxiliary equipment associated with the pump (e.g. motors, belts, drive couplings, reducers, variable speed drives, etc.) during installation, operation and maintenance, all relevant operating instructions should be consulted and recommended procedures should be followed.

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.

First, the selection method of slurry pump

The selection method of slurry pump is relatively simple, mainly according to the characteristics of the material to be transported and the transportation requirements. The following aspects need to be considered when selecting:

1. Material characteristics: mainly includes particle size, content, concentration, temperature, etc. Some materials with large particles or high concentration need to choose a large diameter slurry pump with large flow and high conveying pressure; Some materials with small particles or low concentration can choose a small diameter slurry pump with small flow and low conveying pressure.

2. Conveying distance and head: conveying distance and head determine the conveying capacity and working capacity of the pump, the farther the distance, the higher the head, the need to choose a large slurry pump with large power and large flow.

3. Output flow and transmission efficiency: the larger the output flow, the higher the transmission efficiency, but it also means that the energy consumption is higher. It needs to be selected according to the specific situation.

Two, the main parameters of the slurry pump

1. Flow rate: refers to the volume of liquid transported by the pump per unit time, the unit is m³/h or L/s, which is one of the important parameters of the slurry pump. According to the different conveying materials, the flow is also different, it is recommended to choose the flow that meets the actual needs.

2. Head: refers to the ability to overcome resistance to improve the liquid level height when transporting liquid, the unit is m or kPa. The larger the head, the more it can overcome the transmission resistance, but the more powerful the motor drive is required.

3. Speed: refers to the speed of the pump shaft rotation, the unit is r/min. In general, the higher the speed, the greater the flow of the pump, but the energy efficiency and service life will also be reduced.

4. Efficiency: refers to the proportion of the pump to convert the mechanical energy of the fluid. Efficient pumps reduce fuel consumption, noise and vibration when operating for long periods of time.

5. Sound level: also one of the important parameters. The lower the sound level, the smaller the noise, which is an important indicator of the safe and reliable operation of the slurry pump.

Third, the characteristics of different types of slurry pumps

1. Vertical slurry pump: suitable for conveying materials with higher concentration and larger particles, low noise, high pressure, and good wear resistance.

2. Horizontal slurry pump: suitable for conveying materials with low content and small particles, strengthening liquid flow power and increasing conveying capacity. At the same time, it is also widely used in seabed sediment extraction, artificial sand and pebble transportation and ordinary sand and pebble transportation.

3. High pressure slurry pump: suitable for conveying long distance, high head, high conveying pressure of large engineering occasions, is an indispensable important equipment in petroleum, chemical, mining, metallurgy and other industries.

Four, slurry pump maintenance and maintenance

1. Clean the liquid pipeline and the inside of the pump body to ensure that there is no caking, sediment and water accumulation.

2. Replace the liquid pipeline frequently to avoid long-term load transportation.

3. Regular maintenance and inspection of the rotor, bearing, seal, mechanical seal and other parts of the slurry pump, timely replacement of damaged parts.

4. Keep the pump body clean and check regularly to avoid damage and failure.

5. Prevent slurry pump overload and media backfilling, adjust pump output parameters in time to prevent performance degradation and failure.

The above is about the selection method of slurry pump, parameters, characteristics and maintenance and other aspects of the introduction, hope to be able to buy or use slurry pump users to provide a certain reference.
