Working Principle and Capabilities:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a frequent speed inside 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 may be close to to each other and also to the housing with no actual contacting, so lubrication is pointless within the doing work 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 big difference. Dynamic seal aspect use our patent technologies and imported oil seals, the vibration quantity of shaft to the shaft seals is managed to less than 0.02mm.
A gravity valve is put 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 part is above the weight with the valve, the valve opens automatically, which makes the pressure distinction constantly continue to keep in a fixed controllable value, the value could be the allowable highest stress difference to make sure the pump do the job ordinarily and to ensure that in reality, the roots vacuum pump with overflow valve is really a form of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably increased velocity at rather reduced inlet strain and it is actually possessed overload self-protective function. As it is often a pump of dry clearance seal development, if a specific pumping velocity charge and an ultimate vacuum must be obtained, it’s essential to provide a reduced inlet pressure for cutting down the back movement, therefore, a pump should be backed in use, roots vacuum pump need to be begun quickly soon after its inlet pressure reaches a permissible value for economization.
It truly is permit to select different types of pump since the backing pump for factual requirements, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the fuel containing substantial amount of vapor, the liquid ring vacuum pump is the best backing pump.
