Operating Principle and Features:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a continual pace within the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a gear, which assures these two rotors in specific relative positions. They can be near to one another and also to the housing without the need of real contacting, so lubrication is unnecessary within the working housing. The cautiously balanced operating parts and substantial precision bevel wheels ensue the pump be operated stably and continuously beneath the condition of high-pressure variation. Dynamic seal part 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 put in among the suction and exhaust part of the pump. The function on the gravity valve is as follows, when the pressure distinction amongst the suction and exhaust component is more than the weight with the valve, the valve opens automatically, which helps make the strain distinction normally maintain in the fixed controllable value, the worth will be the allowable highest pressure difference to make certain the pump perform ordinarily and to ensure that in truth, the roots vacuum pump with overflow valve is usually a form of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has substantially higher pace at somewhat decrease inlet pressure and it’s possessed overload self-protective function. Since it is usually a pump of dry clearance seal construction, if a specific pumping speed fee and an greatest vacuum have to be obtained, it truly is required to provide a reduced inlet stress for decreasing the back flow, hence, a pump should be backed in use, roots vacuum pump should be started out quickly soon after its inlet stress reaches a permissible worth for economization.
It’s permit to pick distinct sorts of pump since the backing pump for factual needs, such as oil seal pump and liquid ring vacuum pump. When pumping the fuel containing significant quantity of vapor, the liquid ring vacuum pump would be the best backing pump.
