Working principle of circulating water cooling device for vacuum pump unit What is the working principle of circulating water cooling device of vacuum pump unit? Let's have a brief understanding. Pump the water in the storage tank into the water sprayer, and pump the water to the cooling water inlet of the unitUnder the action of exhaust fan, the water evaporates on the surface, dissipates heat and cools down, and then returns to the water storage tank. The distribution of the holes on the porous plate determines the position of the water column, so that the small holes on the porous plate are evenly distributed, so that the air flow can fully contact the water column and form the surface of swallow hair as large as possible Achieve the purpose of water coolingConsidering that the water discharged from the vacuum unit is far away from the air and the temperature difference between it and the air is relatively large, the first stage of forced cooling with air cooling is designed. The water discharged from the vacuum unit passes through the radiator first, and the radiator is placed behind the fan, and then the cool air passing through the water is blown to the radiator, so that the hot water discharged from the diffusion pump is cooled, and then returned to the water storage tank. The cooling water flow in the diffusion pump can be controlled It was observed directly in the device.Water Ring Vacuum PumpDry Scroll Vacuum Pumpindustrial vacuum pumps,vacuum furnaces

Development of water vacuum pump in electric power industry The basic principles for the development of electric power industry are to improve energy efficiency, protect the ecological environment, develop hydropower in an orderly manner, optimize the development of coal-fired power, actively promote nuclear power generation, moderately develop natural gas power generation, encourage new energy power generation, and drive the technological progress of equipment industry.China will also have an installed capacity of at least 130 million kilowatts, including 40 million kilowatts for hydropower, 60 million kilowatts for thermal power, 70 million kilowatts for nuclear power and 30 million kilowatts for others. During this period, there were more than 500 key projects with an investment of over 100 million yuan, with a total investment of 3 trillion yuan. Among them, there are 207 thermal power projects, 132 hydropower projects, 8 nuclear power projects, 82 wind power projects and 21 biomass power generation projects. Therefore, in the next few years, the power pump market is broad.Of course, Zhonghuan vacuum pump thinks that the key requirement of electric power pump is to adopt various pipeline booster pumps with energy saving, high efficiency and environmental protection, especially the development of nuclear main pump, charging pump, reactor cooling pump, high pressure safety water injection pump, boric acid pump, nuclear first, second and third stage pump, supercritical and ultra supercritical thermal power unit pump, boiler feed water pump, booster pump, circulating pump, condensate pump and water ring Vacuum pump, centrifugal ash pump, reciprocating ash pump, coupling, metering pump, pump for cooling unit, flue gas desulfurization device and other pump products.CL Sereis Cone Liquid Ring Vacuum PumpRoots BlowersRoots Vacuum Pump

Material of rotary vane vacuum pump Data selection of rotary vane vacuum pump: in order to improve the pump speed, reduce wear and temperature, and ensure the normal performance of the pump, one of the key is how to properly select the stator and vane, which is the main friction pair data. Carbon impregnated alloy, a new type of self smoothing data, is commonly used in the rotary vane of direct coupled pump. Some domestic research institutes have also made comprehensive tests on other materials used as spin sheets. The results show that carbon fiber reinforced plastics and polymer liquid crystal data are of development value.As the friction and wear between the vane and the stator of the high-speed direct coupled pump increases, the temperature rise of the pump increases. Therefore, improving the friction, wear and smoothness between the vane and the pump cavity is the key to develop a good performance direct coupled vane pump. Through the analysis and calculation of Elastohydrodynamic smoothing theory, it is found that the motion between the vane and the pump cavity is unreasonable, which makes the wear between the vane and the rotor and the pump chamber more serious, and it is difficult to find a suitable smooth condition, which leads to the increase of temperature rise of high-speed vane pump. The way to deal with the wear is to keep the length unchanged during the rotation. However, the current round pump cavity is impossible to do. In theory, an envelope line of stator pump cavity can be proposed, which is tangent to the outside of envelope circle on a series of axisymmetric curves. Of course, the processing technology of this kind of profile is more laborious than that of circular profile, but the extra cost can be compensated from the improvement of pump performance. Such a pump, vibration, noise, temperature rise, wear will be reduced a lot.Rotor structure and rotor: through the calculation of the geometric pumping speed of the vane pump, it can be seen that when the pump speed has reached a certain high value, increasing the rotor can improve the pumping speed without increasing the rotor eccentricity and the maximum linear speed. Therefore, it is a promising way to improve pumping speed.At present, the direct coupled pump used by domestic manufacturers adopts the structure of three slot integral rotor, which is equipped with three rotors. The integral rotor with three blades has high strength and rigidity, which can reduce the unbalance of rotor at high speed and reduce the impact load of rotor. The geometric pumping speed calculation shows that the pumping speed of the three slot rotor is 18-20% higher than that of the two slot rotor.Water Ring Vacuum PumpDry Scroll Vacuum Pumpindustrial vacuum pumps,vacuum furnaces
