Methods to improve energy saving of horizontal slurry pumps

As we all know, the horizontal slurry pump is an essential piece of equipment in the mineral processing industry. Its main function is to provide power for pipeline transportation.
Due to unreasonable usage methods or blind selection of slurry pumps, problems such as waste of energy consumption and rapid wear of the pumps are caused. In fact, as long as we choose and use the slurry pump correctly and reasonably according to our own situation, we can achieve efficient use of the slurry pump. Below, the technical engineer of Shijiazhuang Shishui Pump Industry Co., Ltd. briefly explains several methods of rational use of slurry pumps:
1. Reasonably select 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 many material choices, many businesses are hesitant. Choose high-chromium cast iron material, which has good wear resistance and is limited to use in mineral processing plants where the slurry contains coarse and sharp materials; high-chromium white cast iron material has good wear resistance, but its toughness is poor and cannot withstand the rapid growth of large solid particles. impact, otherwise the material on the surface of the impeller will fall off, and the cross section will easily 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 it has high elasticity, but it is only suitable for transporting fine 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 flow and lift required.
When selecting a slurry pump, the average user only pays attention to the flow rate selection of the pump and ignores the lift selection of the pump. Some people even think that the higher the lift, the safer it is, so the selected slurry pump has a lift greater than the actual lift demand. A lot of electricity is wasted. The selection of slurry pump should be based on actual lift requirements to reduce the number of installed machines and save electric energy. In addition, it should be noted that when calculating the head, the loss of head needs to be considered to avoid insufficient head of the pump, which will affect the pump filling and discharge efficiency.
3. The power of the motor and the slurry pump must be reasonably matched.
The unreasonable power matching of the motor and the slurry pump is mainly reflected in two aspects: «a big ox pulls a small plow, and a calf pulls a big plow». Especially the first phenomenon is particularly common, and the matching power is selected to be large, resulting in a huge waste of electric energy. big. The supporting power of the latter is selected to be small, that is, «a small cow pulls a big plow», which will cause insufficient slurry supply to 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 a reasonable matching of the power of the motor and the slurry pump.
4. Install the slurry pump scientifically and rationally
If conditions permit, when installing the slurry 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 an «anti-aircraft gun» style. You can install it horizontally or tilted. Installation and other methods to reduce losses. The diameter of the pipeline has a great influence on the loss of head. It is best to use a water pipe diameter slightly larger than the caliber of the slurry pump, which can improve the delivery efficiency of the slurry pump.
The above four are the introduction to the reasonable selection and use of slurry pumps. As long as the mineral processing plant uses these methods reasonably, it can definitely improve the production efficiency of its own mineral processing plant and achieve the purpose of energy saving and high efficiency.
