How to select the appropriate slurry pump model parameters

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.
