Operating Principle and Characteristics: The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a constant speed inside the pump housing for suction and exhaust of gasoline. Two rotors are supported by two bearings and synchronized by a gear, which guarantees these two rotors in sure relative positions. They’re close to to each other and to the housing with out actual contacting, so lubrication is pointless from the doing work housing. The meticulously balanced working components and higher precision bevel wheels ensue the pump be operated stably and constantly under the problem of high-pressure distinction. Dynamic seal portion employs our patent technological innovation and imported oil seals, the vibration level of shaft on the shaft seals is controlled to less than 0.02mm. A gravity valve is installed amongst the suction and exhaust a part of the pump. The function on the gravity valve is as follows, once the pressure difference amongst the suction and exhaust aspect is above the excess weight of your valve, the valve opens automatically, which tends to make the strain distinction generally hold within a fixed controllable value, the worth could be the allowable highest strain difference to ensure the pump perform ordinarily and to ensure that actually, the roots vacuum pump with overflow valve is a type of overload self-protective pump. Series SYF roots vacuum pump with overflow valve has considerably increased pace at relatively reduce inlet strain and it truly is possessed overload self-protective function. Because it is usually a pump of dry clearance seal construction, if a particular pumping pace price 15 and an greatest vacuum need to be obtained, it is necessary to supply a reduced inlet strain for cutting down the back flow, thus, a pump need to be backed in use, roots vacuum pump should be started soon just after its inlet stress reaches a permissible worth for economization. It truly is permit to pick different sorts of pump since the backing pump for factual requirements, such as oil seal pump and liquid ring vacuum pump. When pumping the gas containing significant amount of vapor, the liquid ring vacuum pump could be the great backing pump.
