Working Principle and Capabilities:
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 gasoline. Two rotors are supported by two bearings and synchronized by a gear, which assures these two rotors in certain relative positions. These are close to to one another and to the housing devoid of actual contacting, so lubrication is pointless while in the operating housing. The meticulously balanced operating components and substantial precision bevel wheels ensue the pump be operated stably and constantly beneath the issue of high-pressure variation. Dynamic seal aspect use our patent technology and imported oil seals, the vibration level of shaft on the shaft seals is controlled to less than 0.02mm.
A gravity valve is set up among the suction and exhaust a part of the pump. The function from the gravity valve is as follows, when the stress distinction between the suction and exhaust component is above the weight in the valve, the valve opens immediately, which makes the strain variation normally continue to keep in the fixed controllable worth, the worth could be the allowable highest pressure big difference to make certain the pump do the job ordinarily and to ensure in truth, the roots vacuum pump with overflow valve is really a sort of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has substantially higher velocity at somewhat lower inlet strain and it is actually possessed overload self-protective function. Because it is often a pump of dry clearance seal development, if a specific pumping pace fee and an ultimate vacuum have to be obtained, it is actually required to provide a reduced inlet strain for decreasing the back movement, hence, a pump need to be backed in use, roots vacuum pump ought to be started quickly just after its inlet stress reaches a permissible value for economization.
It’s permit to pick different sorts of pump as the backing pump for factual needs, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the fuel containing huge quantity of vapor, the liquid ring vacuum pump is the best backing pump.
