Working Principle and Characteristics:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a frequent pace within the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a gear, which assures these two rotors in sure relative positions. These are near to one another and also to the housing without the need of actual contacting, so lubrication is unnecessary within the operating housing. The meticulously balanced operating components and high precision bevel wheels ensue the pump be operated stably and continuously underneath the affliction of high-pressure distinction. Dynamic seal component use our patent technology and imported oil seals, the vibration quantity of shaft within the shaft seals is managed to much less than 0.02mm.
A gravity valve is installed in between the suction and exhaust part of the pump. The function from the gravity valve is as follows, once the strain difference amongst the suction and exhaust aspect is in excess of the weight from the valve, the valve opens automatically, which makes the stress variation generally preserve in a fixed controllable value, the worth is the allowable highest pressure distinction to make sure the pump work usually 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 considerably greater pace at fairly reduced inlet pressure and it truly is possessed overload self-protective function. Because it is a pump of dry clearance seal building, if a certain pumping pace price and an greatest vacuum must be obtained, it truly is needed to supply a reduce inlet stress for lowering the back movement, consequently, a pump must be backed in use, roots vacuum pump must be started off soon right after its inlet strain reaches a permissible worth for economization.
It can be permit to select various sorts of pump because the backing pump for factual requirements, such as oil seal pump and liquid ring vacuum pump. When pumping the gasoline containing massive amount of vapor, the liquid ring vacuum pump is the best backing pump.
