Operating Principle and Capabilities:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a frequent pace 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 sure relative positions. They can be close to to each other and also to the housing devoid of actual contacting, so lubrication is pointless inside the working housing. The cautiously balanced operating components and large precision bevel wheels ensue the pump be operated stably and constantly beneath the condition of high-pressure distinction. Dynamic seal component use our patent technological innovation and imported oil seals, the vibration level of shaft about the shaft seals is managed to much less than 0.02mm.
A gravity valve is set up concerning the suction and exhaust a part of the pump. The perform with the gravity valve is as follows, when the pressure variation concerning the suction and exhaust part is above the weight with the valve, the valve opens automatically, which helps make the pressure big difference generally hold in the fixed controllable worth, the value could be the allowable highest strain difference to ensure the pump function generally and to ensure in actual fact, the roots vacuum pump with overflow valve is a type of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably larger speed at relatively decrease inlet strain and it’s possessed overload self-protective function. Because it is usually a pump of dry clearance seal development, if a specific pumping velocity fee and an greatest vacuum must be obtained, it can be necessary to provide a reduced inlet strain for minimizing the back movement, for that reason, a pump must be backed in use, roots vacuum pump really should be began soon just after its inlet stress reaches a permissible value for economization.
It is actually allow to pick different varieties 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 big quantity of vapor, the liquid ring vacuum pump is the best backing pump.
