Operating Principle and Attributes:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a continual velocity within the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a gear, which ensures these two rotors in specified relative positions. They can be near to one another and also to the housing without the need of actual contacting, so lubrication is pointless within the doing work housing. The meticulously balanced working elements and substantial precision bevel wheels ensue the pump be operated stably and constantly beneath the affliction of high-pressure difference. Dynamic seal portion use our patent engineering and imported oil seals, the vibration volume of shaft to the shaft seals is managed to much less than 0.02mm.
A gravity valve is installed involving the suction and exhaust part of the pump. The function of your gravity valve is as follows, once the pressure variation involving the suction and exhaust aspect is over the fat with the valve, the valve opens immediately, which helps make the pressure distinction constantly keep inside a fixed controllable value, the value could be the allowable highest pressure variation to be sure the pump operate normally and to ensure in reality, the roots vacuum pump with overflow valve is a type of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has substantially greater pace at rather decrease inlet pressure and it really is possessed overload self-protective perform. As it can be a pump of dry clearance seal construction, if a particular pumping speed rate and an greatest vacuum should be obtained, it truly is necessary to supply a lower inlet pressure for reducing the back movement, thus, a pump needs to be backed in use, roots vacuum pump needs to be begun quickly just after its inlet pressure reaches a permissible value for economization.
It is actually permit to pick diverse sorts of pump as the backing pump for factual prerequisites, such as oil seal pump and liquid ring vacuum pump. When pumping the gas containing large quantity of vapor, the liquid ring vacuum pump may be the ideal backing pump.
