Аннотация
A new design of a liquid ring vacuum pump is developed providing kinematic closure of the rotating sleeve blades and impeller blades. The design allows to maintain a constant gear ratio from the sleeve to the impeller during interaction of one pair of blades, and as a result, to reduce dynamic loads on the components of the liquid ring vacuum pump, to smooth its operation, and to ensure stability of the liquid ring shape. Structural differences and hydrodynamic features of fluid flow in the working cavity are compared for a liquid ring vacuum pump with a stationary casing and with kinematic closure. It has been established that power consumption for the evacuation process is reduced on average by 35% (by approximately 36 % due to a decrease of the area of bladeless space, and by up to 40% due to a decrease in the friction forces of the fluid in the bladeless space).
