1. Reasonably select the lining material according to the type of ore. There are many types of lining materials for the pump. Faced with the choice of many materials, the high chromium cast iron material is selected, which has good anti-wear performance. Therefore, the selection of 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 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 pump head is greater than the actual head demand, resulting in a lot of waste of electric energy.The selection of the pump should be based on the actual head requirements to reduce the number of installed units and save energy. In addition, you need to pay attention to the loss of head when calculating the head to avoid insufficient head of the pump, which affects the pump's irrigation and drainage efficiency.

 

3. The motor and pump power must be matched reasonably

The unreasonable matching of the power of the motor and the pump is mainly reflected in the two aspects of "the big cow pulls the small plow, and the little cow pulls the big plow"

In particular, the first phenomenon is extremely large, and the matching power is selected to be large, resulting in a very large waste of electric energy. The latter's matching power is selected to be small, that is, "little bull pulls big plow", which will cause insufficient slurry supply of the 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 pump.

 

4. Install the slurry pump scientifically and reasonably

If conditions permit, when installing the pump, try to reduce the amount of elbows, or cancel the "three valves". The pipelines are good, straight and short. Do not set the water outlet pipes as "anti-aircraft guns".

Methods such as horizontal installation and inclined installation can be adopted to reduce loss.

The size of the slurry pump pipe diameter has a great influence on the loss head. It is best to take the water pipe diameter a little larger than the pump caliber to improve the pumping efficiency.

The above is a summary of methods to improve the efficiency of slurry pumps.
