The two rotors of the vacuum pump are operated in relative synchronization by a pair of high-precision gears. The drive shaft is connected to the motor by a coupling. In the transmission structure layout there are two main: one is the motor and gear on the same side of the rotor. Driven rotor is directly driven by the motor end gear, so that the torsional deformation of the active rotor shaft is small, the clearance between the two rotors will not change due to the large torsional deformation of the driving shaft, so that the clearance between the rotors is uniform in the process of operation. When the use of a pump can not meet the requirements of pumping and vacuum, several pumps need to be combined, complementary to meet the process requirements. Some vacuum pumps can not work under atmospheric pressure, the need for pre-vacuum; Some vacuum pump outlet pressure is lower than atmospheric pressure, the need for the former pump, so the pump needs to be used together. The combined use of vacuum pump, we call the vacuum pump unit, it can make the vacuum system to get a better vacuum and exhaust. We should correctly choose the combination of vacuum pumps, because different vacuum pumps have different requirements for the extraction of gas requirements, for example: in general, the roots - rotary unit is not suitable for the system containing more condensable gas. When you choose an oil seal pump, you should first understand whether your vacuum system has requirements for oil pollution. If the equipment strictly requires no oil, should choose a variety of no oil pump, such as: water ring pump, cryogenic pump. If the requirements are not strict, you can choose a pump, plus some anti-oil pollution measures, such as cold well, oil well, baffle, etc., can also meet the requirements of clean vacuum. Know the composition of the pumped gas, whether the gas contains condensable steam, whether there is particle dust, whether there is corrosion, etc. When selecting a vacuum pump, it is necessary to know the gas composition and select the corresponding pump for the pumped gas. If the gas contains steam, particles, and corrosive gases, it should be considered to install auxiliary equipment, such as condenser, dust collector, etc. on the inlet pipe line of the pump. When choosing an oil seal vacuum pump, consider the environmental impact of the oil vapor (soot) emitted by the vacuum pump. If the environment does not allow for pollution, oil free vacuum pumps should be selected, or the oil vapor discharge to the outdoor. Vacuum pump working vibration of the process and the environment has no impact, if the process does not allow, should choose no vibration pump or take anti-vibration measures.
