Learn These 4 Points, And Improving The Efficiency Of The Slurry Pump Is Not A Problem!

Slurry pumps are the best equipment in the ore dressing industry, and their main function is to provide power for pipeline transportation. Due to unreasonable use of slurry pumps or blind choices, the pump's energy consumption and wear too quickly. In fact, as long as we choose and use the slurry pump correctly and reasonably according to our situation, we can use the slurry pump efficiently.

1. Reasonably choose 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-mouth cast iron and wear-resistant rubber. Faced with the choice of many materials, many merchants are undecided. Choose high-chromium cast iron materials, which have good wear resistance and are limited to ore dressing plants with coarse and sharp particles in the slurry; high-chromium white-mouth cast iron materials have good wear resistance, but their toughness is poor and cannot withstand the rapid impact of large solid particles. Otherwise, it will cause the impeller surface material to fall off and the cross-section will easily form pits due to corrosion; the wear-resistant rubber materials are better than metal materials and have high elasticity, but they are only suitable for transporting fine-grain slurry without edges and corners. Therefore, the choice of slurry pump linings must be made reasonably based on the type of ore, so as to improve the usage rate of the pump.

2. Selection of flow and head according to actual required flow rate and head.

Generally, users only pay attention to the flow rate of the pump when selecting a slurry pump and ignore the head selection of the pump. Some people even think that the higher the head, the safer it is. Therefore, the head of the selected slurry pump should be greater than the actual head requirement, and even a lot of electricity is wasted. The choice of slurry pump should be selected according to the actual head requirements to reduce the number of installed machines and save electricity. In addition, it is necessary to pay attention to the point that when calculating the head, it is necessary to consider the loss of the head to avoid insufficient pump head and affecting the pump irrigation and drainage efficiency.

3. The power of the motor and slurry pump must be reasonably matched.

The unreasonable power of the motor and slurry pump is mainly reflected in the two aspects of "big cow pulls a small plow, and a calf pulls a large plow" and especially the phenomenon of the former, which is particularly common. The supporting power is chosen to be too large, resulting in a lot of waste of electricity. The latter's matching power is chosen to be small, that is, "calf pulls a big plow", which will cause insufficient slurry supply to the slurry pump. The motor overload or the inactive pump cannot guarantee the safe and economical operation of the equipment. The solution is to be reasonable in matching the power of the motor and the slurry pump.

4. Install the slurry pump scientifically and reasonably.

If conditions permit, when installing the pump, try to minimize the amount of elbows, or cancel the "three-valve" system. The pipeline is straight and short. Do not set the outlet pipe to "anti-air gun" type. You can use under-lying installation, tilt installation and other methods to reduce losses. The diameter of the pipeline has a great impact on the loss of head. It is best to adopt a grade of slurry pump diameter slightly larger in the water pipe, which can improve the pump's conveying efficiency.
