Working Principle and Capabilities:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a consistent velocity within the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a gear, which guarantees these two rotors in specified relative positions. They are near to one another and also to the housing devoid of real contacting, so lubrication is pointless in the operating housing. The cautiously balanced working components and large precision bevel wheels ensue the pump be operated stably and continuously beneath the affliction of high-pressure variation. Dynamic seal aspect use our patent engineering and imported oil seals, the vibration volume of shaft around the shaft seals is controlled to significantly less than 0.02mm.
A gravity valve is put in in between the suction and exhaust a part of the pump. The function with the gravity valve is as follows, when the stress difference amongst the suction and exhaust portion is above the weight with the valve, the valve opens automatically, which can make the pressure difference always maintain within a fixed controllable worth, the value is the allowable highest pressure big difference to be sure the pump function usually and to ensure in actual fact, the roots vacuum pump with overflow valve is really a sort of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has substantially increased velocity at somewhat decrease inlet strain and it truly is possessed overload self-protective perform. As it is really a pump of dry clearance seal development, if a specific pumping velocity fee and an greatest vacuum must be obtained, it is needed to supply a reduce inlet strain for minimizing the back flow, hence, a pump need to be backed in use, roots vacuum pump should be began quickly just after its inlet stress reaches a permissible worth for economization.
It is permit to pick different sorts of pump as the backing pump for factual demands, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the gas containing significant volume of vapor, the liquid ring vacuum pump could be the ideal backing pump.
