Operating Principle and Features:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a consistent velocity within the pump housing for suction and exhaust of gasoline. Two rotors are supported by two bearings and synchronized by a gear, which ensures these two rotors in certain relative positions. They can be near to one another and to the housing without having actual contacting, so lubrication is unnecessary from the doing work housing. The cautiously balanced operating elements and higher precision bevel wheels ensue the pump be operated stably and constantly below the affliction of high-pressure difference. Dynamic seal element use our patent technology and imported oil seals, the vibration quantity of shaft on the shaft seals is managed to less than 0.02mm.
A gravity valve is set up in between the suction and exhaust a part of the pump. The perform on the gravity valve is as follows, once the pressure distinction amongst the suction and exhaust element is in excess of the weight of the valve, the valve opens instantly, which helps make the stress distinction generally continue to keep in the fixed controllable value, the value will be the allowable highest pressure distinction to ensure the pump function typically and in order that actually, 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 greater speed at reasonably lower inlet strain and it can be possessed overload self-protective function. Because it can be a pump of dry clearance seal building, if a certain pumping pace charge and an ultimate vacuum have to be obtained, it is necessary to provide a decrease inlet pressure for lowering the back movement, for that reason, a pump must be backed in use, roots vacuum pump needs to be commenced soon following its inlet pressure reaches a permissible worth for economization.
It truly is allow to pick distinctive varieties of pump since the backing pump for factual requirements, such as oil seal pump and liquid ring vacuum pump. When pumping the gasoline containing significant volume of vapor, the liquid ring vacuum pump is the excellent backing pump.
