Roots vacuum pump is Ike pump newly developed gear pump, which is developed after the high vacuum gear pump new products, the gear pump for conveying temperature not higher than 140 ℃ of crude oil, sugar, dilute, yeast light alkaline liquid. Roots vacuum pump production from abroad point of view, the Roots pump production is not large, but the price of foreign roots pump is much higher than the domestic pump.At present, almost all large and small domestic and foreign high vacuum and vacuum systems, In order to shorten the pumping time, improve production efficiency are equipped with Roots pump, so the domestic roots pump must occupy the domestic market on the basis of trying to enter the international market, so you must further reduce the domestic vibration noise Roots pump to completely solve the shaft Sealing oil leakage problems to improve the appearance of the pump quality and improve pump finish and cleanliness.In addition, but also taking into account the power frequency of some countries and regions 60Hz, but also to ensure Roots pump speed increase in the case of long-term operation The reliability. At present, the domestic air-cooled straight-line atmospheric roots pump progress quickly, technically mature.Because this pump is equipped with a gas cooler below the exhaust port, a portion of which is cooled by the gas return to the pump chamber to cool Rotor, so that the compression heat is balanced, so this pump can be directly into the atmosphere.In order to meet the requirements of different ultimate vacuum, this pump can be used in series, generally plus an air-cooled front-row atmospheric roots Roots pump, To achieve the ultimate vacuum than the previous stage pump an order of magnitude higher than this pump because there is no working medium in the pump chamber, in fact, is also a dry pump.At present, this air-cooled straight row atmospheric roots pumps and units have been in the oil , Chemical, plastics, pesticides, turbine rotor balancing, aerospace simulation and other devices has been the test of long-term operation, it should be vigorously promote and apply in the country.
