Abstract :
By analyzing the key indicators of rotor profile in roots pump, the reason of constraining the Roots pump to improve the efficiency is identified, on this basis, the conventional involutes profile is improved. Compared with the key indicators of the conventional profile, the improvement profile´s diameter distance ratio and area coefficient are higher clearly. And the improvement profile is smooth.
