The working principle of roots vacuum pump and the working principle diagram

the working principle of roots vacuum pump, roots vacuum pump working principle diagram of

roots vacuum pump, pumping the gas needs to be from the first of the roots vacuum water pump suction mouth in the vacuum between the rotor and the pump body, this time a rotor of roots vacuum pump and vacuum pump body of the suction gas and inspiratory mouth separated, separated gas ( Figure 2 - reference 11 the roots vacuum pump working principle diagram) With the rotation of the rotor continuous process, is to the outlet. Can see FIG. 2 11 the roots vacuum pump working principle diagram of the serial number ( 一) , where V0 inside space is a closed state, so the compression and expansion. But when the rotor rotates to near the outlet of the department, the peak due to the part where V0 vacuum degree is lower than the outlet of the vacuum degree, in order to make the connected to the vacuum inside the average volume, gas will be from the outlet diffusion to the area where V0, it spread direction and the direction of the rotation of the rotor is in different directions. When the rotor to turn again, will put where V0 gas compression to the outlet will be connected part will be in gas, when the rotation of the rotor continuously, has been in the suction process discharge in gas absorption. This operation process is equivalent to the rotor space by mo a minimum increases to a maximum, and then by the maximum reduced to the minimum. This is the working principle of roots vacuum pump.

roots vacuum pump under the condition of suction inlet pressure small runs, usually in the 1000 - due to the rotor speed is high About 3000 r/min, linear velocity close to the thermal motion of molecules on the surface of the rotor speed, in this case the collision on the rotor of the gas molecules are rotor together into larger air outlet, vacuum pump water ring vacuum pump discharge before it was. This is the working principle of the molecular roots vacuum pump.
