Working Principle and Capabilities: The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a continuous pace 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 specified relative positions. They may be close to to one another and to the housing without actual contacting, so lubrication is needless from the doing work housing. The very carefully balanced working elements and high precision bevel wheels ensue the pump be operated stably and continuously under the condition of high-pressure distinction. Dynamic seal portion makes use of our patent technologies and imported oil seals, the vibration volume of shaft on the shaft seals is controlled to significantly less than 0.02mm. A gravity valve is installed among the suction and exhaust a part of the pump. The perform from the gravity valve is as follows, once the strain difference amongst the suction and exhaust portion is over the fat of the valve, the valve opens instantly, which can make the stress variation always keep inside a fixed controllable value, the worth will be the allowable highest strain big difference to make certain the pump get the job done ordinarily and to ensure that in truth, the roots vacuum pump with overflow valve is actually a variety of overload self-protective pump. Series SYF roots vacuum pump with overflow valve has substantially increased pace at reasonably lower inlet stress and it can be possessed overload self-protective perform. As it is really a pump of dry clearance seal building, if a particular pumping pace charge 15 and an greatest vacuum need to be obtained, it’s important to supply a lower inlet stress for lowering the back flow, consequently, a pump need to be backed in use, roots vacuum pump should be begun quickly following its inlet stress reaches a permissible worth for economization. It’s permit to pick diverse 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 substantial volume of vapor, the liquid ring vacuum pump may be the suitable backing pump.
