SU414805A3 - PUMP FOR TRANSFERING GAS AND LIQUID ENVIRONMENT - Google Patents

Description

The invention relates to centrifugal pumps for pumping liquid-fluid media, in particular for pumping frothy fluids: bones, for example, such as fluids, hot water, and: 1 e; o; nc e.} 1 triple slurry, which is difficult to rely on with air entrapment.

From aesosg aasos for pumping gas-liquid media containing a slave, an oche wheel, installed-on the bottom of the vertical wave shaft, a housing covering the impeller and having a suction around the shaft of the shaft in its upper section. The feed chamber is used to receive the pumped medium, the swirling vortex motion: and the non-spreading and its opening in the "bottom" of the hull. The camera is located near the shaft and is reported to: n: isl with blueness Obverse 1B o-rpuse.

(However, in well-known pumps, it is difficult to ensure uninterrupted operation due to the complex separation of gas from the pumped medium.

The aim of the proposal is to intensively separate the gas when creating in the feed chamber and whirling movement by returning to the feed chamber part of the train and train, receiving energy from the impeller inside the case.

This goal is achieved by the fact that the upper cTeiHKa of the body is equipped, at least with a ONE guiding edge, projecting from the periphery of the connected hole in the direction to B1.

Ia: pra; von 1ONe edge (or ribs) may have a different shape, but preferably a cutting edge. Opal Nalra.Vlyusch; e ribs act so that the liquid rotating in; 1 the morning of the hornus is around the vertical of K1al (the axis of the Nassa can rotate between peopaaiH and return: to the feeding chamber without the rotation .

The feeding chamber may be different.

The feeding chamber 6, which surrounds the vertical shaft 2. is an iBBepx expanding, truncated junction 7, n-shaped and connected with the end to the suction inlet 4, and the upper section is to Cc-: lindrical section 8. The top wall 5 of the body 3 is sleep. b0
