ANALYSIS OF THE EXISTING CALCULATION METHODS OF LIQUID RING VACUUM PUMPS

At design of modern liquid - ring vacuum pumps one of important requirements is optimization of key parameters of flow par t. One of the problems is the choice of the corresponding criteria of optimality and operated pa- rameters. In view of the general requirements applied to them it is necessary to consider specific conditions and fea- tures of the designed liquid ring vacuum pu mps. Various methods of calculations of key parameters of liquid ring vacu- um pumps are considered. One of the most perspective directions of further development of modern liquid ring vacuum pumps is allocated.
