Working 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 gas. Two rotors are supported by two bearings and synchronized by a gear, which ensures these two rotors in particular relative positions. They are close to to each other and also to the housing without having actual contacting, so lubrication is unnecessary while in the working housing. The carefully balanced operating components and high precision bevel wheels ensue the pump be operated stably and continuously under the affliction of high-pressure distinction. Dynamic seal portion use our patent engineering and imported oil seals, the vibration quantity of shaft over 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 from the gravity valve is as follows, once the stress variation in between the suction and exhaust aspect is above the bodyweight with the valve, the valve opens automatically, which tends to make the strain big difference generally maintain in a fixed controllable worth, the worth may be the allowable highest strain variation to guarantee the pump get the job done typically and in order that the truth is, the roots vacuum pump with overflow valve can be a variety of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has substantially higher pace at rather lower inlet pressure and it really is possessed overload self-protective perform. Since it is actually a pump of dry clearance seal development, if a certain pumping speed fee and an ultimate vacuum have to be obtained, it is actually required to provide a decrease inlet strain for decreasing the back movement, therefore, a pump must be backed in use, roots vacuum pump must be started off soon soon after its inlet strain reaches a permissible worth for economization.
It is permit to pick distinct types of pump because the backing pump for factual prerequisites, this kind of as oil seal pump and liquid ring vacuum pump. When pumping the fuel containing massive volume of vapor, the liquid ring vacuum pump is definitely the suitable backing pump.
