Reciprocating Compressors – Cylinder/Packing Lubrication System

{0 Comments}

The flow required to lubricate the packing and cylinders is quite small, and the pressure necessary to inject the lubricant at these locations is quite high. Therefore, small plunger pump (force-feed lubricators) systerns are used. The force-feed lubricators are usually driven by the compressor crankshaft. The two basic types of cylinder lubrication systems are the …

Reciprocating Compressors – Frame Lubrication System

{0 Comments}

The frame lubrication system circulates oil to the frame bearings, connecting rod bearings, crosshead shoes, and can also supply oil to the packing and cylinder lubrication system. Splash lubrication systems are the least expensive and are used in small air compressors. Forced-feed systems are used for almost all oilfield gas compression applications. Figure 11-22 shows …

Reciprocating Compressors – Cylinder Cooling

{0 Comments}

Traditional compressor cylinder designs require cooling water jackets to promote uniform distribution of heat created by gas compression and friction. Some of the perceived advantages of water-cooled cylinders are reduced suction gas preheat, better cylinder lubrication, prolonged parts life, and reduced maintenance. Operating experience during the last 30 years has proven that compressor cylinders designed …
