Ways to Improve Energy Saving of Vertical Slurry Pump

Ways to improve the energy saving of Vertical Slurry Pump.

Vertical Slurry Pump are used unreasonably or blindly selected, resulting in waste of pump energy consumption, excessive wear and tear, etc. The following introduces methods to improve the energy saving of Vertical Slurry Pump.

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. Choose high chromium cast iron materials, which have good anti-wear performance. Limited to the use of thick and sharp concentrators in the slurry; high chromium white cast iron material has good wear resistance, but its toughness is poor, and it cannot withstand the rapid impact of larger solid particles. Otherwise, the impeller surface material will fall off and the section will be broken. It is easy to 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 they are only suitable for conveying fine-grained slag without edges and corners. 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 the flow and head according to the actual needs. When selecting the slurry pump, most people only pay attention to the flow selection of the pump and ignore the selection of the pump head. Some people even think that the higher the head, the more secure, so choose the slurry. The pump head is greater than the actual head requirements, and even a large amount of electrical energy 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 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.

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 Vertical 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.

4. Install the Vertical Slurry Pump scientifically and reasonably. If conditions permit, minimize the amount of elbows or cancel the "three valves" when installing the slurry pump. The pipeline is best to be straight and short. Do not set the outlet pipe as an "anti-aircraft gun". ”Type, can adopt methods such as horizontal installation, inclined installation, etc., to reduce loss. 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 slurry pump.
