How to improve working efficiency of slurry pump

The slurry pump is an indispensable equipment in the mineral processing industry, and its main function is to provide power for pipeline transportation. Slurry pumps are used unreasonably or blindly selected, resulting in waste of pump energy consumption and rapid wear. In fact, as long as we choose and use the slurry pump correctly and reasonably according to our own situation, we can use the slurry pump efficiently.

1. Reasonably select the lining material 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 hesitating. Choose high-chromium cast iron materials, which have good abrasion resistance and are only used in concentrators with coarse and sharp pastes; high-chromium white cast iron materials have good wear resistance, but their toughness is poor and cannot withstand large solid particles quickly. Impact, otherwise it will cause the impeller surface material to fall off, and the section will easily form pits due to corrosion; the wear resistance and corrosion resistance of wear-resistant rubber materials are better than metal materials, and they are more elastic, but only suitable for conveying fine particles without edges and corners. Slurry. Therefore, the selection of slurry pump linings needs to be reasonably selected according to the type of ore, so as to increase the utilization rate of the pump.

2. Choose according to the actual flow and head required
When selecting the slurry pump, the general user only pays attention to the flow selection of the pump and ignores the selection of the pump head. Some people even think that the higher the head, the more insurance, so the selected slurry pump head is greater than the actual head demand, and even A large amount of waste of electrical energy should be selected according to the actual head requirements to reduce the number of installed units and save electrical energy. In addition, it is necessary to pay attention to the loss of head when calculating the head to avoid the impact of insufficient head of the pump. Pump irrigation and drainage efficiency.

3. The power of the motor and the slurry pump must be matched reasonably
The unreasonable matching of the power of the motor and the slurry pump is mainly reflected in the two aspects of “the big cow pulls the small plow, and the calf pulls the big plow”. Especially the first phenomenon is extremely large. The matching power is selected to be large, resulting in a very large waste of electricity. . The latter’s matching power is selected to be small, that is, “little cow pulls the big plow”, which will cause insufficient slurry supply of the slurry pump. If the motor is overloaded or the pump cannot be driven, the safe and economical operation of the equipment cannot be guaranteed. The solution must be matched with the power of the motor and the slurry pump.

4. Scientific and reasonable installation of slurry pumps
If conditions permit, when installing the pump, try to reduce the amount of elbows, or cancel the “three valves”. The pipeline is straight and short. Do not set the water outlet pipe to the “anti-aircraft gun” type. You can adopt methods such as horizontal installation, inclined installation, etc. , Reduce loss. The size of the pipe diameter has a great influence on the loss head. It is better to use a slightly larger diameter of the water pipe and the diameter of the slurry pump to improve the delivery efficiency of the pump.
