Operating Principle and Functions: 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 particular relative positions. They may be close to to one another and to the housing with no real contacting, so lubrication is unnecessary while in the working housing. The carefully balanced working elements and substantial precision bevel wheels ensue the pump be operated stably and continuously underneath the problem of high-pressure variation. Dynamic seal component employs our patent technologies and imported oil seals, the vibration quantity of shaft within the shaft seals is managed to much less than 0.02mm. A gravity valve is put in amongst the suction and exhaust a part of the pump. The perform with the gravity valve is as follows, once the pressure big difference involving the suction and exhaust portion is in excess of the excess weight from the valve, the valve opens instantly, which can make the stress big difference always maintain in the fixed controllable worth, the worth would be the allowable highest stress big difference to make sure the pump perform generally and to ensure in reality, the roots vacuum pump with overflow valve is actually a variety of overload self-protective pump. Series SYF roots vacuum pump with overflow valve has substantially larger pace at rather reduce inlet pressure and it is actually possessed overload self-protective perform. Since it is often a pump of dry clearance seal building, if a particular pumping velocity fee 15 and an greatest vacuum must be obtained, it’s essential to provide a lower inlet pressure for minimizing the back flow, thus, a pump should be backed in use, roots vacuum pump must be started off quickly soon after its inlet stress reaches a permissible worth for economization. It can be permit to pick different kinds of pump as the backing pump for factual specifications, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the gasoline containing large amount of vapor, the liquid ring vacuum pump will be the great backing pump.
