Water diversion, self-priming, Suction These are the main parameters of miniature pumps, explained in detail below: ã€Water diversion】 In the water pump industry, water diversion specifically refers to the use of water. Because some pumps in the work, you must manually add water to make the pump within the formation of a closed environment, pump parts and then move to create a partial vacuum in order to allow external water pressure inside and outside the pressure at atmospheric pressure into the pump inlet to complete the water absorption action . For example, in the past, water pumps commonly used in rural areas had to be supplemented with water before the water in the wells could be sucked up. [Self-absorption] is mainly used in pumps, pumps, is a more important parameter. 1. The meaning of self-absorption As the name implies, self-priming fingers have the ability to automatically absorb water, that is, before the pump work, even if the inlet pipe is full of air without the need to pre-add water, the pump will be automatically lower than the pump The side of the water pumping up and then discharged. 2. The principle of self-priming Pump in the water pipe is the case of air, the use of negative pressure pump (vacuum), under the action of atmospheric pressure will be lower than the water pressure on the pump up, and then discharged from the drain side of the pump . Before this process does not require additional water (water guide). Pumps with this capability are called self-priming pumps. Some centrifugal or rotary vane pump in the water before, you must add water in the pump chamber to form a closed environment, and then pump operation to form a negative pressure, to achieve the purpose of water. For example, manual pumps were used in rural areas. Pumps that do not have self-priming capabilities require extra water before each use. [Suction] the height of self-absorption is called suction process. 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 self-priming 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 level, 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 at most one of the atmospheric pressure on the water pressure The height of 10.3 meters (because of the atmospheric pressure ≈ 10.3 meters water pressure), so the maximum self-suction is about 10.3 meters. For example, there is a miniature pump BSP27250S self-priming suction up to 5 meters, even higher.
