Working Principle and Attributes:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a continual pace inside the pump housing for suction and exhaust of fuel. Two rotors are supported by two bearings and synchronized by a gear, which ensures these two rotors in certain relative positions. They are near to each other and also to the housing without the need of real contacting, so lubrication is needless from the working housing. The carefully balanced operating parts and large precision bevel wheels ensue the pump be operated stably and constantly beneath the problem of high-pressure difference. Dynamic seal part use our patent technologies and imported oil seals, the vibration volume of shaft on the shaft seals is controlled to less than 0.02mm.
A gravity valve is put in in between the suction and exhaust a part of the pump. The perform from the gravity valve is as follows, when the stress difference amongst the suction and exhaust part is above the fat in the valve, the valve opens instantly, which makes the pressure distinction always hold in a fixed controllable value, the worth may be the allowable highest strain difference to make sure the pump perform typically and in order that in fact, the roots vacuum pump with overflow valve is a sort of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably higher pace at somewhat decrease inlet strain and it’s possessed overload self-protective function. Because it is really a pump of dry clearance seal construction, if a specific pumping speed price and an greatest vacuum need to be obtained, it is essential to supply a lower inlet pressure for lowering the back flow, thus, a pump need to be backed in use, roots vacuum pump ought to be started quickly following its inlet pressure reaches a permissible value for economization.
It truly is permit to select different kinds of pump because the backing pump for factual necessities, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the gasoline containing significant quantity of vapor, the liquid ring vacuum pump is definitely the perfect backing pump.
