7VP-20/220 reciprocating compressor

Compressor 7VP-20/220 piston, crosshead, four-stage, angular, water-cooled, lubricated cylinders and oil seals.

The compressor 7VP-20/220 includes the following main components: base, cylinders and electric motor.

The base consists of unified units of the crank mechanism (crankshaft, connecting rod, crosshead), the frame, the lubrication unit of the movement mechanism and the lubricator (for the lubrication of cylinders and oil seals). The frame is cast iron, box-shaped, with internal reinforcement ribs. In the upper part of the frame, there are hatches that are tightly closed with lids, providing access to the details of the movement mechanism.

The lower part of the frame serves as an oil reservoir. An oil level indicator is mounted on the top of the frame. Special tides are available for attaching the compressor cylinders to the frame. In the holes of the transverse ribs of the frame, crosshead cast-iron sleeves are installed, which serve as guides for crossheads. The crankshaft is stamped steel, with cranks for connecting rods, supported by roller bearings. For angular bases, the crankshaft is single-crank, and for balancing, counterweights are installed on the shaft.
