Vacuum pumps are devices that take place, improve and vacuum in a variety of closed spaces. Vacuum pump can be defined as: chemical or physicochemical means to be pumped by the container to obtain vacuum equipment or equipment. With the development of vacuum applications, a variety of vacuum pumps have been developed, pumping speed from a few liters per second to hundreds of thousands of liters per second, millions of liters.
Working principle of vacuum pump:
According to the principle of vacuum pump, the vacuum pump can basically be divided into two types, that is, gas transmission pump and gas trap pump. As the demand for the pressure scale is wider and wider in the field of vacuum application and scientific research, most of the demand is required by several vacuum pump vacuum pumping systems after pumping gas together, because the operation scale of the vacuum operation is very wide, so the vacuum pump can not complete the scale of the operation pressure, only depending on the size of the vacuum pump. According to different requirements of operation, vacuum pumps are used.
In order to make use of the needs of convenient and various vacuum technological processes, water ring vacuum pumps sometimes combine various vacuum pumps in accordance with their functional requirements and use the type of units in the type of units. The operation principle of various vacuum pumps: water ring vacuum pump / liquid ring vacuum pump operation principle water ring vacuum pump is a kind of crude vacuum pump, water ring pump can also be used as a tightening machine, called a water ring type compressor, is a compact machine attributable to low pressure.
Application field of vacuum pump:
Water ring pumps are used as self priming pumps and gradually used in many industrial sectors such as petroleum, medicine and food. In the process of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing, water ring pump has been widely used. Because of the rapid development of vacuum, the water ring pump has always been the focus of attention in obtaining coarse vacuum. Because the compressed gas in the water ring pump is isothermal, it can extract flammable and explosive gases, in addition to dust, so the use of water ring pump is increasing.
Water is used as the operating fluid in the pump body. When the impeller is rotated in the clockwise direction of the drawing, the water is thrown near the impeller. Because of the effect of the centrifugal force, the water forms a closed ring that is determined by the pump approximately equal to the same thickness. The lower part of the water ring is tangent to the impeller hub, and the upper part of the water ring touches the top of the blade.
