Working Principle and Characteristics:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a continual pace within 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 are really near to one another and to the housing with no real contacting, so lubrication is pointless during the operating housing. The carefully balanced working elements and higher precision bevel wheels ensue the pump be operated stably and constantly beneath the problem of high-pressure variation. Dynamic seal aspect use our patent engineering and imported oil seals, the vibration level of shaft within the shaft seals is controlled to much less than 0.02mm.
A gravity valve is installed in between the suction and exhaust a part of the pump. The function on the gravity valve is as follows, when the stress variation amongst the suction and exhaust element is more than the fat with the valve, the valve opens automatically, which helps make the pressure difference always preserve inside a fixed controllable worth, the value is the allowable highest pressure big difference to make certain the pump do the job usually and in order that in fact, the roots vacuum pump with overflow valve is actually a type of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has substantially larger velocity at rather decrease inlet strain and it truly is possessed overload self-protective perform. Since it is really a pump of dry clearance seal building, if a particular pumping velocity fee and an greatest vacuum must be obtained, it’s required to supply a lower inlet strain for minimizing the back flow, thus, a pump need to be backed in use, roots vacuum pump should be began quickly just after its inlet strain reaches a permissible value for economization.
It is actually permit to select distinctive types of pump since the backing pump for factual demands, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the gas containing substantial volume of vapor, the liquid ring vacuum pump could be the ideal backing pump.
