They are designed for the supply of compressed air to pneumatic tools, accessories, mechanisms; pneumatic conveyers for conveyance of loose materials (sand, cement, grain, etc.)
Application:
– as components of oil and gas drilling rigs;
– at machine-building enterprises;
– in petrochemical, gas, metallurgical, electrochemical, mining and other industries.
The compressors are four-cylinder, two-stage, piston-type machines driven from an electric motor via a flexible coupling. Lubricant is forced fed into the system. Cooling of the cylinders and the cooler is performed by air. Pressure relief and condensate drain are automatic.
Compressors are completed with the automatic control and protection system which ensures:
– automatic maintenance in the air receiver of the prescribed pressure value by the compressor start-stop as well as by the air bypassing from the discharge side to the suction one;
– relief and blowoff of the compressor on its stopping;
– oil electric heating in crankcase (for the version to be used in northern areas);
– availability of relief and blowoff of the compressor with the help of the control board in the manual mode;
– emergency stop on compressed air overheating;
– emergency stop on inadmissible pressure drop in the lubrication system.
Compressors can be delivered with relay or microprocessor automatic system.
