Pumps in the industrial production, agricultural production, marine production and other fields to play this very important role in accelerating the research and understanding of the pump, both from the user's point of view or from a business point of view is very important, in which the pump The working principle is to use the most basic and core knowledge of the pump. This should arouse more people's attention and care. Pump working principle Pump working principle: Pump is to transport liquid or liquid pressurized machinery. It will be the prime mover mechanical energy or other external energy transfer to the liquid, the liquid energy increases, mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspension and liquid metal, but also can be transported liquid, gas mixture As well as liquids containing suspended solids. Pump performance measurement of the technical parameters of flow, suction lift, lift, shaft power, water power, efficiency, etc .; according to different working principle can be divided into volume pumps, vane pumps and other types. Volumetric pumps utilize the variation of their working chamber volume to transfer energy. Vane pumps use the interaction of rotating blades and water to transfer energy, such as centrifugal pumps, axial flow pumps, and mixed flow pumps. After the pump is turned on, the impeller rotates at a high speed in the pump body. Before the pump is turned on, the pump body must be filled with liquid. The liquid in the pump body rotates with the impeller. Under the action of centrifugal force, the liquid is thrown out by the impeller at the product outlet. Of the liquid in the pump chamber diffusion speed becomes slower, the liquid is thrown out, the center of the impeller to form a vacuum low pressure zone, liquid in the liquid pool under the action of atmospheric pressure, the suction pipe into the pump. Pump body diffusion chamber volume is certain, with being thrown out of the liquid increases, the pressure is also gradually increased, and finally discharged from the pump outlet. As a result, the liquid is sucked up continuously from the sump and discharged continuously from the pump outlet. The most important role of the pump is to achieve liquid delivery or liquid pressurization, its main types include: positive displacement pump and vane pump. With the rapid development of industries such as urban water supply, sewage system, building system, agricultural and water conservancy system, ship system, petrochemical system and light industry system in our country, the demand and requirement for water pump in these fields are also constantly improving. The significance of national defense and people's livelihood is extraordinary.
With the advent of an aging society, the voice of installing elevators in elevator free residential buildings is getting higher and higher. This is the rigid demand of many elderly people, and the problem of going upstairs and downstairs is a life problem that these elderly people have to face many times every day. Adding elevators to old buildings can improve the travel conditions of the elderly living in buildings without elevators. Professional Adding Elevator manufacturer is located in China, including Install Elevator,Modern Elevator,Modern Residential Elevators, etc.
