Learn These 4 Points To Improve The Working Efficiency Of Slurry Pumps Reasonably And Cleverly.

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 methods or blind choices of the pump, the pump's energy consumption and wear occur too quickly. In fact, as long as we choose and use the slurry pump correctly and reasonably according to our own situation, we can use the pump efficiently.

1. Reasonably choose lining materials according to the type of ore.

There are many types of lining materials for 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 uncertain. Choose high-chromium cast iron materials, which have good wear resistance and are suitable for 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 in terms of elasticity, but they are only suitable for transporting fine-grain slurry without edges and corners. Therefore, the choice of pump linings requires reasonable selection based on the type of ore, so as to improve the usage rate of the pump.

2. Select 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. Some even think that the higher the head, the safer it is, so they choose a pump with a head much greater than the actual requirement, resulting in a lot of electricity waste. The pump should be selected according to the actual head requirements to reduce the number of installed machines and save electricity. In addition, when calculating the head, it is necessary to consider head loss to avoid insufficient pump head affecting irrigation and drainage efficiency.

3. Ensure reasonable matching of motor and pump power.

Unreasonable power matching between the motor and the pump is mainly reflected in two aspects: "a big horse pulls a small cart" and "a small horse pulls a big cart". The former refers to choosing an excessively large supporting power, leading to a lot of electricity waste; the latter refers to choosing an excessively small matching power, which will cause insufficient slurry supply to the pump, motor overload, or pump failure to operate, failing to guarantee safe and economical operation of the equipment. The solution is to reasonably match the power of the motor and the pump.

4. Install the slurry pump scientifically and reasonably.

If conditions permit, during installation, try to minimize the number of elbows or cancel the "three-valve" system. The pipeline should be straight and short, and the outlet pipe should not be set to the "anti-air gun" type. Methods such as under-lying installation and tilt installation can be used to reduce losses. The diameter of the slurry pump pipeline has a great impact on head loss; it is best to adopt a slightly larger pump diameter, which can improve the pump's delivery efficiency.
