Vacuum pump 120 cubic meters per hour (working fluid)
The rotational and outward center of the propeller around the axis of the vacuum pump in the inner cylinder of the water forms a water ring.
In the course of time, with the entry and exit of the blades in the water, the volume of the space between the two cylinders, both the blades and the inner wall of the water ring increases on one side (the suction area) and the suction is performed and reduced to the other side (Dash area) and Density action.
The cooling operation of the vacuum pump is carried out by water, and the condensate of the water with the exhaust air and returning it to the pump can also be used, which results in the cooling of the pump and the stabilization of the temperature of the reaction of compression isotermically.
