Four Methods To Improve The Energy Saving Of Slurry Pumps

As we all know, the slurry pump is an indispensable equipment in the beneficiation industry, and its main function is to provide power for pipeline transportation.

Slurry pumps are used unreasonably or blindly selected, which leads to problems such as waste of energy consumption and excessive wear of the pump. 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. Next Depump Technology SJZ CO.,LTD. will briefly explain several methods for the rational use of slurry pumps:

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 hesitating. Choose high-chromium cast iron material, which has good abrasion resistance, and is only used in concentrators where the slurry contains coarse and sharp; high-chromium white cast iron material has good wear resistance, but its toughness is poor, and it cannot withstand large solid particles quickly. Otherwise, it will cause the impeller surface material to fall off, and the section will easily form pits due to corrosion; the wear-resistant and corrosion-resistant properties of wear-resistant rubber materials are better than those of metal materials, and they are more elastic, but only suitable for conveying thin without edges and corners. Granule 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.

Select 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 should be greater than the actual head demand, and even A large amount of electrical energy is wasted.
The choice of slurry pump should be selected according to the actual head requirements, in order to reduce the number of installed machines and save electricity. In addition, it should be noted that when calculating the head, it is necessary to consider the loss of the head to avoid insufficient pump head, which affects the pump irrigation and drainage efficiency.

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 particularly large, and the matching power is selected to be large, resulting in a great waste of electricity. Big. 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.

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 is best to be straight and short. Do not set the water outlet pipe into an "anti-aircraft gun" type. You can install it underneath, inclined installation, etc. Method to reduce losses. The size of the pipe diameter has a great influence on the loss head. It is best to use a water pipe with a slightly larger diameter of the slurry pump to improve the delivery efficiency of the pump.


The above four are the introduction to the reasonable selection and use of slurry pumps. As long as the concentrator uses these methods reasonably, it will definitely improve the production efficiency of its own concentrator and achieve the purpose of energy saving and high efficiency.
