Working Principle and Features:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a consistent speed within the pump housing for suction and exhaust of fuel. Two rotors are supported by two bearings and synchronized by a gear, which ensures these two rotors in certain relative positions. They are close to to one another and to the housing with no actual contacting, so lubrication is pointless while in the functioning housing. The meticulously balanced working parts and large precision bevel wheels ensue the pump be operated stably and constantly underneath the ailment of high-pressure variation. Dynamic seal element use our patent engineering and imported oil seals, the vibration amount of shaft within the shaft seals is managed to significantly less than 0.02mm.
A gravity valve is set up between the suction and exhaust part of the pump. The function from the gravity valve is as follows, when the pressure variation between the suction and exhaust portion is in excess of the fat from the valve, the valve opens automatically, which tends to make the pressure big difference normally retain within a fixed controllable value, the value would be the allowable highest pressure difference to make certain the pump get the job done normally and to ensure that in fact, the roots vacuum pump with overflow valve is usually a type of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably increased pace at rather reduce inlet pressure and it is possessed overload self-protective perform. Because it is actually a pump of dry clearance seal construction, if a particular pumping pace fee and an ultimate vacuum should be obtained, it can be needed to provide a lower inlet stress for cutting down the back movement, thus, a pump should be backed in use, roots vacuum pump ought to be started off quickly right after its inlet strain reaches a permissible worth for economization.
It is allow to select diverse types of pump because the backing pump for factual necessities, such as oil seal pump and liquid ring vacuum pump. When pumping the gas containing huge amount of vapor, the liquid ring vacuum pump will be the perfect backing pump.
