Improving the Efficiency of a Guarded-Vane Vacuum Pump

The article presents a modernized construction of a vane pump in which engineering solutions to reduce the degree of wear of the work surfaces of the parts of the pump are implemented. The use of a new design of the working plates and reinforcement of the slots of the pump rotor with inserts of wear-resistant structural materials produce an increase in the operating reliability of the pump, an increase in the pump discharge, and an increase in the length of the turnaround cycle.
