How to choose the right slurry pump to extend its service life
Published:
Oct 18,2024
If the correct choice of slurry pump can make the extension of service life
Slurry pump service life of many factors, including the following:
1) Medium characteristics (such as solid particle size, particle shape and hardness, mixture concentration and acid reduction, etc.)
2) Operating conditions (such as pump flow, head and speed, etc.)
3) Hydraulic design and structural parameters of pump flow parts (such as outlet and inlet diameter and width of pump impeller, etc.)
4) Material properties (such as hardness, tensile strength, wear resistance, etc.).
The following will introduce to you that if the slurry pump is correctly selected, the service life can be prolonged.
1, reasonable product selection: including the wear resistance of the materials used in the flow components and other manufacturing quality of the pump. In the selection design, it is necessary to take into account the above factors, the slurry pump for a reasonable selection.
2. Layout of the slurry pump: In the layout of the slurry pump, the cavitation margin of the pump should be considered to minimize the loss of the suction pipeline.
3. The design flow rate of the slurry pump should be as small as possible: due to the flow of the slurry in the pump body, the slurry has impact and friction on the bearing parts in the slurry pump body, which leads to wear of the bearing parts. Obviously, the same slurry and flow rate, the slower the flow rate of the slurry, the slower the wear rate of the wear parts of the pump, and the longer the service life of the pump.
4. The lower the pump speed, the better: Because the lower the pump speed, the lower the relative speed between the impeller of the slurry pump and the slurry, that is, the lower the relative speed with the ore particles, so the slurry pump impeller The slower the wear speed. In addition, different slurry pump to achieve the same flow, generally is the impeller diameter when the speed is low, the impeller diameter when the speed is high.
