Working Principle and Options: The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a consistent speed inside the pump housing for suction and exhaust of gasoline. Two rotors are supported by two bearings and synchronized by a gear, which ensures these two rotors in specific relative positions. They may be near to each other and also to the housing without the need of actual contacting, so lubrication is pointless while in the working housing. The meticulously balanced operating components and high precision bevel wheels ensue the pump be operated stably and continuously beneath the affliction of high-pressure big difference. Dynamic seal component uses our patent technology and imported oil seals, the vibration amount of shaft around the shaft seals is managed to significantly less than 0.02mm. A gravity valve is put in among the suction and exhaust part of the pump. The perform of the gravity valve is as follows, when the pressure difference among the suction and exhaust part is above the excess weight from the valve, the valve opens automatically, which tends to make the pressure difference usually hold in a fixed controllable value, the worth could be the allowable highest pressure big difference to guarantee the pump work commonly and so that in actual fact, the roots vacuum pump with overflow valve is usually a sort of overload self-protective pump. Series SYF roots vacuum pump with overflow valve has substantially higher speed at comparatively reduce inlet strain and it’s possessed overload self-protective perform. As it is often a pump of dry clearance seal development, if a specific pumping speed charge 15 and an greatest vacuum should be obtained, it is important to provide a decrease inlet pressure for lowering the back movement, hence, a pump have to be backed in use, roots vacuum pump ought to be started out soon right after its inlet stress reaches a permissible value for economization. It is permit to pick different kinds of pump because the backing pump for factual needs, such as oil seal pump and liquid ring vacuum pump. When pumping the gas containing substantial amount of vapor, the liquid ring vacuum pump is definitely the excellent backing pump.
