Analysis Of The Relationship Between Wear Resistance And Service Life Of Wear-resistant Slurry Pumps

Analysis of the relationship between wear-resistant slurry pumps and service life　　Abrasion-resistant slurry pumps are mainly used as conveying equipment and are widely used and are involved in mining, electricity, coal, environmental protection, metallurgy, rivers and other industries.For example, the slurry conveying of ore dressing plants, the coal slurry and heavy media conveying of coal washing plants, and the sludge conveying of rivers and rivers, etc., can also be used in the chemical industry to transport some corrosive slurry containing crystals.At present, 80% of wear-resistant slurry pumps are widely used in factory selection to transport slurry. Whether the flow rate, rotation speed and other parameters of wear-resistant slurry pumps are reasonable directly affects the life of wear-resistant slurry pumps.Choosing the appropriate working parameters can not only give full play to the performance of the slurry pump, but also improve the service life. If the selection is improper, it will cause the wear-resistant slurry pump to not work normally, and may even cause the factory to be selected to stop production.In order to fully utilize the performance of the wear-resistant slurry pump, it is necessary to fully understand the relationship between the slurry flow rate, rotation speed, etc. and the life of the wear-resistant slurry pump in actual work.Due to the flow of the ore slurry in the wear-resistant slurry pump, the ore slurry will cause impact and wear on the inner lining of the pump body. Obviously, with the same ore slurry flow rate, the slower the slurry flow rate, the lighter the wear of the pump body, and the longer the service life of the wear-resistant slurry pump.Therefore, the design flow rate should be as small as possible while ensuring the efficiency of the wear-resistant slurry pump.Furthermore, the lower the pump speed, the lower the relative speed of the impeller and the slurry will be, and the slower the wear speed of the impeller will be.In addition, at the same flow rate, the larger the diameter of the impeller, the lower the rotation speed, the fewer ore particles per unit area, and the wear of the impeller is lighter.Therefore, the correct choice should be a large pump with low speed. Due to its light wear, it can extend the service life of the wear-resistant slurry pump and reduce costs.In addition to the flow rate and rotation speed, the head also has a certain impact on the life of the wear-resistant slurry pump. The actual head of the wear-resistant slurry pump must be controlled within the bearable range. Otherwise, too high head will lead to excessive flow of the wear-resistant slurry pump. On the one hand, it will cause evacuation, which will lead to damage to the wear-resistant slurry pump. On the other hand, it will increase wear and reduce service life.To extend the service life of the wear-resistant slurry pump, you can also start with the lining material and choose high wear-resistant and corrosion-resistant materials as the lining, which has excellent wear resistance, strength and elasticity.It can also be directly molded into a slurry pump overflow part, which not only ensures wear resistance, but also avoids leakage. It can be used to transport various materials with strong acids, strong alkalis and strong corrosiveness.The wear-resistant slurry pump is to lining the wear-resistant rubber into the slurry pump, thereby greatly enhancing the wear-resistant slurry pump's wear-resistant slurry pump and solving the problem of low life of the wear-resistant slurry pump.The wear-resistant slurry pump has low operating noise and low vibration; it is strong and durable, has a long service life, spacious runners and good corrosion resistance.Wear-resistant slurry pumps can be widely used in mining, metallurgy, electricity, coal, chemical, building materials and other industries.
