The compressor station SK-12-2R2
The compressor station SK-12-2R2 is intended for operation as a part of stationary pneumatic cement storages. The station consists of a compressor equipped with an electric motor and installed on a frame, treatment systems for intake and discharge air (optional) and a control system. Cement is loaded into and unloaded from the storage pneumatically, i.e. by pumping air out from vessels (optional) or into vessels, respectively. Climatic modification “У”, arrangement category 3 in accordance with GOST 15150.
The compressor station is quite compact, requires minimal space for installation, convenient in maintenance operations. For its transportation, any suitable vehicles can be used (roads of 1-5 categories), as well as railway and waterborne carriages.
In order to ensure safe operation of the compressor and its unloaded startup (mandatory condition), a manifold is installed on its outlet equipped with check and safety relief valves, as well as a ball cock.
The station must operate in recursive short-time mode. Duration of the operating cycle must not exceed 1 hour. Interval between the cycles must be at least 30 minutes.
