In the process of application of vacuum pump unit, its main role is to improve the vacuum degree of vacuum system and the pumping speed under high vacuum environment. Since there is no gas contraction in the operating process of roots pump, when roots pump directly discharges into the atmosphere, the pressure difference between suction port and exhaust port is too large, which will overload the vacuum pump. If the power of vacuum pump motor is simply increased, it will constitute a vacuum pump Heat causes the tiny gap between the vacuum pump rotors to be quickly blocked by heat shrinkage.
In order to ensure that the vacuum pump unit can reach a higher vacuum, it is necessary to ensure the gap between the vacuum pump rotors. Therefore, it is necessary to set up a front stage pump when the vacuum pump is used. The vacuum pump can be started when the pressure in the system is pumped to a certain range with the front stage pump, so as to avoid overload of the vacuum pump. The front stage pump can choose screw vacuum pump, rotary vane vacuum pump, scroll vacuum pump and other vacuum pumps which can discharge air directly.
Under normal conditions, the vacuum degree of a single screw vacuum pump can be better than 2-3 water ring or reciprocating vacuum unit. If the demand still insists on higher pumping speed in high vacuum environment, it is recommended to use with vacuum pump. Our vacuum pump adopts hydraulic coupling planning, which can start the unit at the same time under normal pressure. Due to the early intervention of the pump, the pumping speed of our unit is increased by more than 30% compared with the traditional unit.
