2BV water ring vacuum pump rotates the conveying fluid by means of the periodic transformation of multiple fixed volume conveying units in the working chamber, so as to change the volume of the water pump, so as to form a high vacuum degree and discharge pressure.Let's take a look at how 2BV water ring vacuum pump rotates.2BV water ring vacuum pump realizes its relative synchronous operation through a pair of high-precision gears. The driving shaft is connected with the motor through a coupling. The motor and gear are placed on the same side of the rotor. The driven rotor is directly driven by the motor end gear, so that the torsional deformation of the driving rotor shaft is small, and the gap between the two rotors will not change due to the large torsional deformation of the driving shaft, so the gap between the rotors is uniform during operation.With the continuous development of the times, the word 2BV water ring vacuum pump is more and more well known and its application is gradually popularized. The rotating streamline structure of 2BV water ring vacuum pump and no dead center and non-metallic parts in the rotor chamber avoid pollution to the transported substances.
