TRANSPORT COMPRESSOR PLANT Russian patent published in 2005 - IPC

FIELD: mechanical engineering; diesel locomotives, excavators, electric locomotives.

SUBSTANCE: proposed transport compressor plant contains compressor with drive electric motor controlled by pressure relay provided with making and breaking contacts and heat exchanger, cutoff valve, adsorber with blowing valve controlled by electromagnetic valve, dry air main line, check valve, air collector, all connected in series with compressor. It has main line for blowing through absorber with reservoir-accumulator of regeneration air connected in parallel with dry air main line before check valve and check valve and restrictor, time relay with coil and contact, all parallel-connected before input of reservoir-accumulator. Contacts of time relay are breaking. Other cutoff valve is arranged in parallel to cutoff valve located between heat exchanger and absorber being controlled by electromagnetic valve connected to breaking contact of time relay. Coils of time relay, blowing valve and cutoff valve of regeneration main line are connected to making contact of pressure relay.

EFFECT: improved efficiency of drying of compressed air and reliability of plant, increased service life of plant.
