1. Reasonable selection of lining materials according to the type of ore:
There are many types of lining materials for slurry pumps, such as high-chromium cast iron, high-chromium white cast iron, and wear-resistant rubber. Faced with the choice of many materials, many businesses are hesitant. Choose high-chromium cast iron material, which has good anti-wear performance, and is limited to use in concentrators containing coarse and sharp particles in the slurry; high-chromium white cast iron material has good wear resistance, but its toughness is poor, and it cannot withstand the rapid acceleration of large solid particles. Otherwise, the material on the surface of the impeller will fall off, and the cross-section is easy to form pits due to corrosion; the wear-resistant and corrosion-resistant performance of wear-resistant rubber materials is better than that of metal materials, and its elasticity is large, but it is only suitable for transporting thin materials without edges and corners. grain slurry. Therefore, the selection of slurry pump linings needs to be reasonably selected according to the type of ore, so as to improve the utilization rate of the pump.
2. Select according to the actual required flow and head:
Generally, when selecting a slurry pump, users only pay attention to the selection of the flow rate of the pump, and ignore the selection of the head of the pump. Some people even think that the higher the head, the safer it is, so the head of the selected slurry pump should be greater than the actual head demand. A lot of waste of electric energy. The selection of the slurry pump should be chosen according to the actual head demand, so as to reduce the number of installed machines and save electric energy. In addition, it should be noted that when calculating the head, the loss head needs to be considered to avoid insufficient head of the pump, which will affect the efficiency of pump irrigation and drainage.
3. The power of the motor and the slurry pump must be matched reasonably:
The power of the motor and the slurry pump is unreasonably matched. The supporting power is selected to be large, resulting in a huge waste of electric energy. However, if the supporting power of the latter is selected to be small, the amount of slurry supplied by the slurry pump will be insufficient. If the motor is overloaded or does not move the pump, it cannot guarantee the safe and economical operation of the equipment. The solution must be to match the power of the motor and the slurry pump reasonably.
4. Scientific and reasonable installation of slurry pump:
If conditions permit, when installing the pump, try to reduce the amount of elbows or cancel the "three valves". The pipeline should be straight and short. Do not set the outlet pipe in the "anti-aircraft gun" style. You can install it lying down or tilting it. method to reduce loss. The diameter of the pipeline has a great influence on the loss head. It is better to use a grade with a slightly larger diameter of the water pipe than the diameter of the slurry pump, which can improve the delivery efficiency of the pump.
