FIELD: engines and pumps. ^ SUBSTANCE: invention relates to machine building, particularly to displacement-type devices, namely to devices designed to pump over fluids by acting upon them with compressed or rarified medium. For this the proposed device comprises a vessel with pressure-reducing valve to adjust pressure inside aforesaid vessel and unions to feed compressed air and to discharge cleaning compound. It also incorporates ejectors with active and passive nozzles and a pressure-reducing valve. Note that the latter has its inlet communicated, via the valve and union, with the compressed air source, and its outlet connected to the reducing valve inlet to adjust medium pressure inside the vessel and, via the valve, to the ejector active nozzle. Note also that the ejector passive nozzle is connected, via the valve and hose, with the vessel inside space. The ejector outlet is connected, via the union and hose, with the turbo compressor labyrinth seals. ^ EFFECT: expanded performances due to formation, at device outlet, of cleaning solution air emulsion and possibility to diagnose labyrinth seal state prior to and after cleaning. ^ 2 dwg |
