Working Principle and Attributes:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a continuous velocity inside the pump housing for suction and exhaust of fuel. Two rotors are supported by two bearings and synchronized by a gear, which guarantees these two rotors in specified relative positions. They are close to to each other and also to the housing without real contacting, so lubrication is pointless from the operating housing. The carefully balanced operating parts and large precision bevel wheels ensue the pump be operated stably and constantly below the condition of high-pressure distinction. Dynamic seal portion use our patent engineering and imported oil seals, the vibration amount of shaft around the shaft seals is managed to less than 0.02mm.
A gravity valve is set up amongst the suction and exhaust part of the pump. The perform of the gravity valve is as follows, when the pressure difference amongst the suction and exhaust portion is in excess of the excess weight with the valve, the valve opens instantly, which can make the pressure difference normally preserve within a fixed controllable worth, the value is definitely the allowable highest strain distinction to guarantee the pump work usually and so that in actual fact, the roots vacuum pump with overflow valve is a variety of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably higher speed at reasonably lower inlet stress and it is possessed overload self-protective perform. As it is actually a pump of dry clearance seal development, if a certain pumping velocity price and an ultimate vacuum have to be obtained, it is essential to supply a reduce inlet stress for cutting down the back flow, as a result, a pump has to be backed in use, roots vacuum pump must be started quickly soon after its inlet stress reaches a permissible value for economization.
It’s allow to pick diverse kinds of pump as 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 will be the excellent backing pump.
