Working Principle and Capabilities:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a constant pace 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 selected relative positions. They are near to each other and to the housing with no actual contacting, so lubrication is pointless during the operating housing. The meticulously balanced working elements and substantial precision bevel wheels ensue the pump be operated stably and continuously beneath the condition of high-pressure variation. Dynamic seal aspect use our patent technology and imported oil seals, the vibration quantity of shaft to the shaft seals is controlled to significantly less than 0.02mm.
A gravity valve is installed amongst the suction and exhaust part of the pump. The function of the gravity valve is as follows, once the pressure difference among the suction and exhaust part is above the fat of your valve, the valve opens instantly, which can make the stress big difference generally maintain within a fixed controllable worth, the worth is definitely the allowable highest strain variation to make sure the pump operate typically and so that in truth, the roots vacuum pump with overflow valve is often a type of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably increased speed at relatively reduced inlet strain and it really is possessed overload self-protective function. Because it is a pump of dry clearance seal building, if a specific pumping speed fee and an ultimate vacuum must be obtained, it’s needed to provide a decrease inlet pressure for cutting down the back flow, hence, a pump should be backed in use, roots vacuum pump ought to be began soon immediately after its inlet pressure reaches a permissible value for economization.
It’s permit to pick unique 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 quantity of vapor, the liquid ring vacuum pump is the suitable backing pump.
