Working Principle and Attributes: The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a constant pace 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 specified relative positions. These are close to to one another and also to the housing with no real contacting, so lubrication is needless during the operating housing. The meticulously balanced operating components and substantial precision bevel wheels ensue the pump be operated stably and constantly beneath the condition of high-pressure distinction. Dynamic seal component utilizes our patent technologies and imported oil seals, the vibration amount of shaft over the shaft seals is controlled to significantly less than 0.02mm. A gravity valve is put in concerning the suction and exhaust part of the pump. The function in the gravity valve is as follows, when the strain variation involving the suction and exhaust element is over the weight on the valve, the valve opens automatically, which makes the stress big difference always preserve in a fixed controllable worth, the value could be the allowable highest strain distinction to guarantee the pump function normally and so that the truth is, the roots vacuum pump with overflow valve is a type of overload self-protective pump. Series SYF roots vacuum pump with overflow valve has substantially larger pace at rather reduce inlet strain and it can be possessed overload self-protective perform. As it is really a pump of dry clearance seal building, if a specific pumping pace fee 15 and an ultimate vacuum need to be obtained, it can be needed to supply a decrease inlet strain for reducing the back movement, as a result, a pump have to be backed in use, roots vacuum pump must be commenced quickly after its inlet pressure reaches a permissible value for economization. It is actually permit to select diverse types of pump because the backing pump for factual demands, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the gas containing large volume of vapor, the liquid ring vacuum pump may be the excellent backing pump.
