How can slurry pump achieve energy saving and consumption reduction?

Slurry pump is used for slurry transportation in mining and metallurgical industry. At present, the form of environmental protection is becoming increasingly serious, and more and more attention is paid to the green sustainable development of various industries. Based on the concept of energy conservation and emission reduction, enterprises should try to reduce energy consumption in the design. Here are some ways to save energy on your pumps. So, can the slurry pump achieve the purpose of energy saving and consumption reduction?

1, according to the actual flow and head selection

Misunderstandings often occur when selecting slurry pumps. Many users only pay attention to the choice of pump flow, but ignore the choice of pump head, they even think that head. Therefore, the selected head is greater than the actual demand of the head, resulting in a large amount of wasted power. In fact, the pump can be selected according to the actual flow and pulp situation, thus reducing the installed capacity and saving energy. It is worth noting that the head loss should be taken into account when calculating the head of the slurry pump to avoid the shortage of head affecting the transportation efficiency.

2, motor and pump power should be reasonable match

The unreasonable match between motor and pump power is mainly reflected in the two aspects of "big ox pulling a small plow" and "small ox pulling a big plow". This leads to a huge waste of electrical energy. If you choose a smaller motor power, that is, "calf plough", it will lead to insufficient pump water, motor overload or slurry pump no movement, can not ensure the normal and stable operation of the pump. Therefore, the power of the motor and the pump should be reasonably matched to achieve the ideal effect.

Slurry pump is a kind of machinery which uses centrifugal action to increase the energy of solid-liquid mixed medium and convert electric energy into kinetic energy and potential energy of medium. It is mainly used in mining, power plant, dredging, metallurgy, chemical industry, building materials and petroleum industries.

Under the action of centrifugal force, the liquid is thrown from the middle of the impeller to the outer edge to obtain energy, and leaves the outer edge of the impeller at high speed and enters the volute pump shell. In the cochlear pump shell, the liquid is slowed down by the gradual expansion of the flow path, and then part of the kinetic energy is converted into static pressure energy, which flows into the discharge pipe at a higher pressure and is sent to the desired place. When the liquid flows from the middle of the impeller to the outer edge of the slurry pump, a certain vacuum is formed in the middle of the impeller. Because the pressure above the tank level is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller.

To sum up, the slurry pump can achieve the purpose of energy saving and consumption reduction. In principle, it belongs to a kind of centrifugal pump, which is mainly used in the mud conveying system of converter dust removal water, blast furnace gas washing water, continuous casting turbid ring water and steel rolling turbid ring water.
