Working 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 inside the pump housing for suction and exhaust of fuel. 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 each other and to the housing with no actual contacting, so lubrication is unnecessary in the operating housing. The cautiously balanced working parts and high precision bevel wheels ensue the pump be operated stably and continuously below the problem of high-pressure variation. Dynamic seal component use our patent engineering and imported oil seals, the vibration volume of shaft around the shaft seals is controlled to less than 0.02mm.
A gravity valve is set up involving the suction and exhaust a part of the pump. The perform of your gravity valve is as follows, once the stress big difference in between the suction and exhaust element is more than the bodyweight with the valve, the valve opens instantly, which helps make the pressure distinction usually keep within a fixed controllable worth, the value would be the allowable highest strain variation to ensure the pump operate ordinarily and in order that in reality, the roots vacuum pump with overflow valve is usually a type of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has substantially increased pace at somewhat reduced inlet stress and it is possessed overload self-protective perform. As it is often a pump of dry clearance seal construction, if a certain pumping pace fee and an ultimate vacuum need to be obtained, it is essential to provide a decrease inlet stress for reducing the back flow, thus, a pump have to be backed in use, roots vacuum pump ought to be began quickly following its inlet stress reaches a permissible worth for economization.
It’s allow to select different kinds of pump as the backing pump for factual demands, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the fuel containing huge level of vapor, the liquid ring vacuum pump could be the ideal backing pump.
