Operating Principle and Functions:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a consistent velocity inside 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 selected relative positions. They may be close to to one another and also to the housing without actual contacting, so lubrication is pointless inside the doing work housing. The thoroughly balanced working elements and substantial precision bevel wheels ensue the pump be operated stably and constantly beneath the issue of high-pressure difference. Dynamic seal portion use our patent technologies and imported oil seals, the vibration volume of shaft over the shaft seals is managed to significantly 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 part is more than the fat of your valve, the valve opens instantly, which tends to make the strain distinction constantly continue to keep within a fixed controllable worth, the worth could be the allowable highest pressure variation to guarantee the pump get the job done normally and so that the truth is, the roots vacuum pump with overflow valve is usually a sort of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably greater velocity at somewhat lower inlet stress and it really is possessed overload self-protective perform. As it is often a pump of dry clearance seal construction, if a particular pumping velocity price and an greatest vacuum must be obtained, it really is necessary to supply a lower inlet pressure for decreasing the back movement, hence, a pump needs to be backed in use, roots vacuum pump must be started off quickly after its inlet pressure reaches a permissible value for economization.
It is allow to pick unique sorts of pump as the backing pump for factual requirements, such as oil seal pump and liquid ring vacuum pump. When pumping the gas containing large quantity of vapor, the liquid ring vacuum pump would be the suitable backing pump.
