What is the working principle of the suction pump? Introduction of suction pump working principle

What is the working principle of the suction pump? We all know that the suction pump is pumping water machinery, the pump body, the rotating assembly, the faucet assembly, drain cover, and the inlet pipe, out Water pipes, blocking the overall network assembled. Below, Asia Fluid Network Xiaobian for you more detailed introduction to the principle of suction pump to answer your doubts on the working principle of the suction pump. What is the working principle of the suction pump? Suction pump principle of operation Introduction Suction pump principle of work Suction pump principle of work in the water, as the name implies, the pump suction pipe is the case of air, the use of pump work when the negative pressure (vacuum), under the action of atmospheric pressure Lower than the water pressure on the pump, and then discharged from the pump drain. This process is not before the need to add "diversion (guide water)". Pumps with this capability are called "self-priming pumps." According to the working principle of the suction pump, some centrifugal or rotary vane pumps must add a "water diversion" to form a closed environment in the pump chamber before the water is absorbed, and then the pump operates to form a negative pressure so as to achieve the purpose of water absorption. For example, manual pumps were used in rural areas. There is no self-priming pump, each time before adding water, "diversion", it is very troublesome. Suction pump working principle Suction Suction height is called suction process. The unit is generally meters. Also known as the maximum height of self-absorption. That is, the maximum height at which the pump can automatically suck water (the vertical distance between the pump suction opening and the liquid to be sucked in) without adding water. Our pumps are suction pumps, the standard suction refers to this situation. Some centrifugal pumps do not have the ability to self-priming, the first use must add water Caixing. Although some diaphragm pumps also have self-priming capability, but the subject of the suction and the inlet pipe are often all the air can draw water under the vertical height difference, this point, please note. Suction pump suction principle of the level of work, with the pump power, flow, structure, etc. are related, but limited by the volume, power, the general self-priming suction miniature pump is not easy to do higher, because the most atmospheric pressure The pressure can be 10.3 meters above sea level (due to a pressure of ≈ 10.3 meters water column pressure), so the maximum self-suction is about 10.3 meters. However, in practice, due to sealing performance reasons, the suction is generally not more than 6.5 meters. Above is the Asian fluid network Xiaobian introduce you to the working principle of the suction pump, I hope you absorb the working principle of the pump and learn to help. (Editor: Qian Wen QQ:)
