Operating Principle and Features:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a continual speed within the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a gear, which guarantees these two rotors in sure relative positions. They may be close to to one another and also to the housing devoid of actual contacting, so lubrication is pointless in the doing work housing. The thoroughly balanced operating components and large precision bevel wheels ensue the pump be operated stably and continuously underneath the condition of high-pressure big difference. Dynamic seal element use our patent technological innovation and imported oil seals, the vibration amount of shaft about the shaft seals is controlled to less than 0.02mm.
A gravity valve is installed between the suction and exhaust a part of the pump. The perform of your gravity valve is as follows, once the strain distinction amongst the suction and exhaust portion is over the excess weight in the valve, the valve opens instantly, which can make the strain big difference usually hold inside a fixed controllable value, the worth could be the allowable highest pressure big difference to guarantee the pump work normally and in order that in actual fact, the roots vacuum pump with overflow valve is actually a sort of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably higher pace at rather reduce inlet strain and it really is possessed overload self-protective perform. Because it is often a pump of dry clearance seal development, if a specific pumping speed fee and an ultimate vacuum should be obtained, it is essential to supply a reduce inlet strain for reducing the back flow, consequently, a pump has to be backed in use, roots vacuum pump really should be started off soon following its inlet strain reaches a permissible value for economization.
It really is allow to select different varieties of pump since the backing pump for factual prerequisites, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the fuel containing significant volume of vapor, the liquid ring vacuum pump will be the great backing pump.
