摘要

FIELD: engines and pumps.;SUBSTANCE: structural-technological model range of chemical pumps includes a set of pumps. Each pump of the row is made as follows as per a single-type system: it is centrifugal, one-stages; it includes a rotor shaft and an impeller and consists of flow and travel parts. The pump travel part housing includes bearing supports. The flow part housing is provided with a flow cavity combined with a spiral collector of pumped liquid with diffusion airfoil gradient of 1÷70 m2/m. The impeller is of a closed type and has the main and covering discs and a system of blades. The main disc is protected on the rear side with a hydraulic lock containing an impeller in the form of an independent disc. The flow part housing is equipped with an detachable annular wall geometrically coordinated with the hydraulic lock. The least of outside radii of the above wall is equal at least to the wheel flow-through radius of the wheel, and hydraulic lock impeller radius is equal at least to the wheel radius. The main wheel disc is equipped with an annular comb and a through opening.;EFFECT: increasing service life, durability, operating reliability of pump operation, pumping efficiency, protection against leakages of pumped media and noxious fumes to atmosphere.;21 cl, 7 dwg
