FIELD: engineering industry. ^ SUBSTANCE: ejector is meant for transporting various working media. Ejector consists of a hollow casing with a side branch, a nozzle having outside thread at the inlet and connected to the hollow casing by means of a connection preventing nozzle rotation, and a mixing chamber, which are installed in hollow casing coaxially, thus forming therebetween a receiving chamber, diffuser and control mechanism equipped with rotation device thereof, which is rigidly attached to hollow casing. Nozzle is installed in hollow casing so that it can be moved axially, and is connected thereto by means of a key joint. At the outlet, nozzle is equipped with a hard-alloy head fixed by means of a bushing. Mixing chamber is rigidly connected to diffuser and fixed in hollow casing by means of a coupling nut. Control mechanism consists of a casing of bulk bearings, which is made in the form of a stepped bushing with inside thread that is a mating part relative to nozzle outside thread. Inside the casing of bulk bearings there rigidly installed is a branch pipe the middle part of outer surface whereof is made in the form of inner body meant for single bulk bearing, and the outlet end of branch pipe is located in nozzle inner part. Rotation device of control mechanism is made in the form of handles. ^ EFFECT: improving ejector operating efficiency. ^ 1 dwg |
