Root Vacuum Pumps

Working Principle and Functions:
The series SYF roots vacuum pump is with overflow valve. The figure-of-eight rotors are counter-rotating at a frequent pace within the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a gear, which guarantees these two rotors in sure relative positions. These are near to one another and to the housing without the need of actual contacting, so lubrication is unnecessary in the operating housing. The meticulously balanced working components and high precision bevel wheels ensue the pump be operated stably and continuously underneath the affliction of high-pressure distinction. Dynamic seal component use our patent technological innovation and imported oil seals, the vibration quantity of shaft within the shaft seals is managed to much less than 0.02mm.
A gravity valve is put in between the suction and exhaust part of the pump. The function from the gravity valve is as follows, once the strain variation amongst the suction and exhaust portion is in excess of the weight of the valve, the valve opens automatically, which makes the stress variation constantly preserve in a fixed controllable value, the value is definitely the allowable highest pressure distinction to make sure the pump do the job usually and in order that in truth, the roots vacuum pump with overflow valve is really a type of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has considerably higher pace at relatively reduced inlet strain and it really is possessed overload self-protective perform. Because it is a pump of dry clearance seal building, if a certain pumping pace rate and an ultimate vacuum must be obtained, it really is needed to supply a reduce inlet stress for lowering the back movement, therefore, a pump must be backed in use, roots vacuum pump must be commenced soon right after its inlet strain reaches a permissible worth for economization.
It can be permit to select various kinds of pump as the backing pump for factual prerequisites, such as oil seal pump and liquid ring vacuum pump. When pumping the gas containing massive amount of vapor, the liquid ring vacuum pump is the best backing pump.
