Operating Principle and Attributes:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a frequent velocity inside the pump housing for suction and exhaust of fuel. Two rotors are supported by two bearings and synchronized by a gear, which assures these two rotors in sure relative positions. They’re close to to each other and also to the housing with no actual contacting, so lubrication is unnecessary while in the working housing. The very carefully balanced operating components and substantial precision bevel wheels ensue the pump be operated stably and continuously underneath the affliction of high-pressure big difference. Dynamic seal part use our patent technological innovation and imported oil seals, the vibration quantity of shaft on the shaft seals is controlled to much less than 0.02mm.
A gravity valve is set up amongst the suction and exhaust a part of the pump. The perform in the gravity valve is as follows, when the stress difference amongst the suction and exhaust component is above the weight from the valve, the valve opens immediately, which can make the stress difference always keep in a fixed controllable value, the worth could be the allowable highest strain distinction to guarantee the pump get the job done normally and so that in 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 larger speed at fairly decrease inlet stress and it’s possessed overload self-protective function. Because it is actually a pump of dry clearance seal construction, if a certain pumping velocity charge and an ultimate vacuum must be obtained, it is actually necessary to provide a lower inlet strain for cutting down the back flow, consequently, a pump must be backed in use, roots vacuum pump should be started out soon immediately after its inlet pressure reaches a permissible worth for economization.
It can be allow to pick distinctive kinds of pump because the backing pump for factual necessities, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the gas containing significant level of vapor, the liquid ring vacuum pump could be the perfect backing pump.
