VKU 1/10 screw compressor system for pneumatic support of electro-rolling stock;
FSUE "KB " Arsenal" started the works on making a compressor in 1997. The result is creation of VKU-1 screw compressor system for pneumatic systems of electro-rolling stock.
Its key advantages are:
— Steadiness of supply of compressed air into the network (without pulsation);
— All the parts (valves, piston rings, crank gear) do not wear out rapidly;
— Absence of any part that would have reciprocal motion, which could result to vibration;
— Low oil entrainment;
— Operation is able at low temperatures below 0°C;
— Long working life;
— Low temperature of compressed air.
