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 gasoline. Two rotors are supported by two bearings and synchronized by a gear, which assures these two rotors in specific relative positions. They are close to to each other and to the housing devoid of real contacting, so lubrication is pointless from the doing work housing. The very carefully balanced working components and high precision bevel wheels ensue the pump be operated stably and constantly under the situation of high-pressure big difference. Dynamic seal part use our patent engineering and imported oil seals, the vibration quantity of shaft around the shaft seals is managed to much less than 0.02mm.
A gravity valve is set up among the suction and exhaust a part of the pump. The perform from the gravity valve is as follows, once the pressure difference between the suction and exhaust component is more than the bodyweight of the valve, the valve opens automatically, which tends to make the stress distinction normally maintain within a fixed controllable worth, the value will be the allowable highest pressure big difference to guarantee the pump do the job commonly and to ensure the truth is, the roots vacuum pump with overflow valve is actually a variety of overload self-protective pump.
Series SYF roots vacuum pump with overflow valve has substantially greater pace at somewhat decrease inlet strain and it can be possessed overload self-protective function. Since it is actually a pump of dry clearance seal construction, if a specific pumping velocity rate and an greatest vacuum should be obtained, it is essential to provide a decrease inlet stress for decreasing the back movement, as a result, a pump should be backed in use, roots vacuum pump need to be commenced quickly soon after its inlet stress reaches a permissible value for economization.
It truly is allow to pick different kinds of pump because the backing pump for factual prerequisites, such as oil seal pump and liquid ring vacuum pump. When pumping the gas containing large quantity of vapor, the liquid ring vacuum pump could be the suitable backing pump.
