The K890-122-1 compressor is designed to compress raw oil gas at gas-processing plants and field compressor stations and to supply it to the common collector.
The compressor represents a twocylinder twelve–staged machine. Each cylinder includes six stages. The rotor of each cylinder has its own optimum speed. The step-up gears are installed between the L.P. cylinder and el. motor drive, as well as between the cylinders.The tightness of the compressor cylinders is provided by the end face seals.
Gas and oil are cooled in the aircoolers.
