Summary Of Reasons For Excessive Power Consumption Of Slurry Pumps

Summary of the reasons for excessive power consumption of slurry pumps　　Slurry pumps are generally used in large-scale industrial applications. The actual products can be widely used in mining, electricity, metallurgy, coal and other industries for transporting slurries containing abrasive solid particles.Specifically, it is used in metallurgical ore dressing plants, hydro ash removal in thermal power plants, coal slurry and heavy media transmission in coal washing plants, etc.It can also be used in the chemical industry, and some corrosive slurries containing crystals can be transported, which requires a special material to be completed.The common application scope of slurry pumps is that in the mining industry, about 80% are used in mineral processing plants in the mining industry.The initial ore selection working conditions are relatively bad, and slurry pumps are mainly used as the conveying medium. Therefore, in this stage, the service life of slurry pumps is generally low.Facing different ores, the abrasive properties are different, so high chromium alloys are now used as the main slurry pump material.There are many materials for the slurry pump's overflow parts. The main operation process of the slurry pump is to drive the impeller to rotate at high speed and generate centrifugal force, and send the material out through the impeller.During operation, the overflow impeller volute must withstand the erosion, wear and corrosion of materials.Therefore, the wear resistance and corrosion resistance of the slurry pump overflow parts is an important indicator for measuring the quality of the slurry pump.The slurry pump often has excessive power consumption during use. In response to this problem, the technicians of the slurry pump company summarized the following reasons: 1. The viscosity of the conveyed liquid becomes larger; 2. The speed of the slurry pump becomes higher; 3. The specific gravity of the conveyed liquid exceeds the original design value; 4. The size of the water pump impeller is too large; 5. The resistance of the pipeline system exceeds or is not enough to be sufficient to the predetermined value; 6. There is friction between the rotor parts and the stator parts; 7. The flow of the slurry pump is too large; 8. The pressure of the mechanical seal on the seal seat is too large, and the bearing is worn or damaged; 9. The head of the slurry pump is too low and the flow is too large; 10. There is friction between the rotor parts and the stator parts; In addition, such as the slurry pump balance device does not work, the thermal expansion of different parts in the slurry pump is uneven, etc. are also the reasons for excessive power consumption of the slurry pump.
