Root Vacuum Pumps

Operating Principle and Characteristics:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a constant speed 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 may be close to to each other and to the housing without the need of actual contacting, so lubrication is unnecessary from the operating housing. The very carefully balanced working components and higher precision bevel wheels ensue the pump be operated stably and constantly beneath the situation of high-pressure big difference. Dynamic seal part use our patent technology and imported oil seals, the vibration level of shaft to the shaft seals is controlled to much less than 0.02mm.
A gravity valve is put in amongst the suction and exhaust a part of the pump. The function with the gravity valve is as follows, when the stress distinction involving the suction and exhaust element is in excess of the bodyweight with the valve, the valve opens instantly, which can make the pressure distinction generally retain in the fixed controllable value, the value may be the allowable highest strain variation to be sure the pump get the job done normally and to ensure that in fact, the roots vacuum pump with overflow valve can be a sort of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably larger pace at comparatively reduce inlet stress and it is actually possessed overload self-protective function. Since it is often a pump of dry clearance seal building, if a particular pumping pace fee and an ultimate vacuum need to be obtained, it is needed to supply a decrease inlet strain for lowering the back movement, hence, a pump have to be backed in use, roots vacuum pump must be started out soon just after its inlet pressure reaches a permissible value for economization.
It is actually permit to pick various types of pump since the backing pump for factual demands, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the gasoline containing significant volume of vapor, the liquid ring vacuum pump will be the suitable backing pump.
