centrifugal pump is better or self-priming pump is better? This comparison depends on where the pump is used, not the same, the self-priming pump may be a centrifugal pump, and the centrifugal pump may not be a self-priming pump. Suction pump, when it is started once, self-priming centrifugal pump must inject a certain amount of start-up circulating water; each time the centrifugal pump is started, the inlet pipe and the pump body need to be filled with water at the same time, or the inlet pipe must be filled with auxiliary devices. Exhaust.
The difference between a centrifugal pump and a self-priming pump:
1. The advantages are different
has stable structure and is easy to operate. High efficiency, long service life, and strong self-priming ability.
centrifugal pump has the advantages of compact structure, wide flow range, and wide head. It is more suitable for mildly corrosive liquids, multiple control methods, uniform flow, and stable operation.
2, the composition is different
The basic structure of the centrifugal pump consists of six parts, namely the impeller and the pump. Body, pump shaft, bearing, sealing ring, stuffing box and self-priming pump. Self-priming pump is composed of suction chamber, liquid storage chamber, scroll chamber, liquid return hole, gas-liquid separation chamber, etc.
3. Working principle is different
Centrifugal pump is to use the rotation of the impeller to make the water centrifugal movement to work.
4. A self-priming pump can be used in any environment where a centrifugal pump can be used. The centrifugal pump does not have the function of a self-priming pump. If you need to achieve the function of a self-priming pump, you need to install a bottom valve at the bottom of the pool. The secondary pump and the inlet pipeline are filled with liquid, and can suck in liquid.
centrifugal pumps are mainly used in liquid transportation, cooling systems, industrial cleaning systems, aquaculture systems and industrial equipment. They are also widely used in electric power, metallurgy, coal, building materials, etc. Transportation in the industry. Self-priming pumps are used in the transportation of acid and alkaline media such as clean water or seawater.
Which is better, centrifugal pump or self-priming pump? The above is about centrifugal pumps and self-priming pumps. Introduced, the working principles and advantages and disadvantages of the two products are different. If you have relevant needs, you can contact us directly and we will be happy to serve you!
