The pump-to-point system provides each lubrication point with its own lubricator pump. For very cold installations, immersion heaters and special lube oils must be considered. – Stainless steel downstream of filters. T/F: The hermetic reciprocating compressor motor is essentially made of the same materials as an open type compressor motor. Major components and considerations of a forced feed lubrication system are as follows: Lubrication Engineers can help by recommending lubrication reliability best practices – including the right oil – for most compressor types, whether they are centrifugal compressors, reciprocating compressors, rotary screw compressors, rotary vane compressors or dry screw compressors. The two basic types of cylinder lubrication systems are the pump-topoint system and the divider-block system. Proudly powered by WordPress. Pump with pump heads Reciprocating compressors are among the many lubrication systems we have developed. – Should start automatically when supply pressure falls below a certain level. – No galvanizing. For more than 90 years, the brand has been standing for top quality, constant innovation and high safety standards. – Lube oil system from pump discharge to the distribution system should be flushed with lube oil at 160°F-180°R Oil should flow across a 200 mesh screen and flushing should cease when no more If the lube oil temperature gets too cold, the oil becomes too viscous and does not flow and lubricate properly. Not all lubrication systems in compressors work the same way. Therefore, small plunger pump (force-feed lubricators) systerns are used. Splash lubrication systems are the least expensive and are used in small air compressors. The reciprocating compressor consists of a small pump system which is driven by compressor crankshaft. Reciprocating compressors work in the same manner as automotive engines, with pistons that move back and forth inside of a closed cylinder. How does the compressor lubrication system differ between a reciprocating and a centrifugal compressor? – Driven from crankshaft. 6. In this design, the supply from the sump is essential to keeping the whole system lubricated and functioning properly. Compressor Cylinder Lube Oil System . Forced-feed systems are used for almost all oilfield gas compression applications. False. • Oil cooler Vapor-compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. Proudly powered by WordPress. T/F: Rotary compressors have pistons that rotate inside the cylinders. – Backup for the main oil pump. lo a forced-feed lubrication system, a pump circulates lubricating oil through a cooler and filter to a distribution system that directs the oil to all the bearings and crosshead shoes. Recip-Compressor Pump-to-Point Cylinder & Packing Lubrication is part 11 of the Dresser-Rand Reciprocating Products 19-part training series.. This oil comes in contact with and thus contaminates the gas being compressed. There are generally three types of lubrication systems in reciprocating compressors.They are for high-pressure, low-pressure, and oil-free air compressors.. High-pressure air compressor cylinders (except for nonlubricated compressors) are generally lubricated by an adjustable mechanical force-feed lubricator. In reciprocating compressor, the lubricating oil pump is driven by compressor shaft whereas in centrifugal compressor, the oil pump is driven by separate motor. We have also found that neither of the two traditional types of lubrication system can give users reliable exact lubrication delivery. – Electric motor driven. A reciprocating compressor is a positive-displacement machine that uses a piston to compress a gas and deliver it at high pressure. © 2021 Oil & Gas Process Engineering. Positive-displacement compressors use their lubrication system to provide additional functions. The details of any one system will vary greatly. Crane lubrication . For natural gas engine/compressor lubrication systems. whether lubricated or non-lubricated. Lubrication System. – Keeps oil temperature below 165°F. Type drive: Rotary; Cam: Single lobe; Only Model 130201BCC comes complete with pump heads; Recommended camshaft speed (RPM) for all pumps: 12 to 75 rpm; MCLP output (per pump) = Input speed x decimal ratio x pump output factor = pints per day Pump without pump heads. – Size should be determined by vendor; in lieu of other information use API 618 requirements. Packing/cylinder lubrication can be provided from a forced feed compressor lube oil system. • Pre-lube pump Solutions for special applications . • Oil filter Type of lubrication system; Reciprocating compressors Operation… Reciprocating compressors incorporate a cylinder and piston, piston rings, inlet valve, discharge valve and a drive assembly consisting of a crankshaft, connecting rod and drive, such as an electric motor. It is a more technically advanced and usually more costly method, but it results in longer life for a compressor. The compressors ensure that the refrigerant flows readily through the system. Figure 11-22 shows a splash lubrication system where an oil ring rides loosely and freely on the rotating shaft, dipping into the oil sump as it rotates. Splash lubrication systems are the least expensive and are used in small air compressors. – Should be sized to deliver 110% of the maximum anticipated flow rate. Thus, if the compressor cylinders and packing require six lubrication points, the lubricator box would be supplied with six cam driven pumps. Lube System Installation The CPI lubrication installation team has experience with most compressor environments and specializes in reciprocating compressors. – No socket welding or other pockets that can accumulate dirt downstream of filter. For many years, this was the traditional approach to lubricating a reciprocating air compressor. Our compressor audits have shown that over or under-lubrication affects at least one-third of all reciprocating compressors. This operations-focused course familiarizes operators and maintenance technicians with a typical reciprocating compressor, pump-to-point type, cylinder and packing lubrication system. Being one of the more traditional compressor designs, reciprocating compressors are still common in many applications with low-volumes and high-pressure requirements. Splash lubrication. 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. Theme: Ari by Elmastudio. Not every reciprocating compressor design works this way, but it is possible for the drive engine pump to share some of its lubrication with the compressor. • Overhead day tank Oil is supplied to this system from the frame lube oil system or from an overhead tank. * Auxiliary pump – Should be equipped with a level indicator, Compressor Lubricating Oil System Operation The lube oil system (Figure 4) supplies oil to the compressor and driver bearings and to the gears and couplings. Lubrication Systems . Progressive lubrication systems . Cylinder lubrication system for diesel engines . Therefore, small plunger pump (force-feed lubricators) systerns are used. Rotary Screw Compressor – A screw air compressor uses a pair of helical screws to drive air into the chamber and shrink the chamber to compress the air. – Carbon steel lines should be pickled, passivated, and coated with rust inhibitor. The lubrication package is fabricated in-house for consistency and the highest possible quality control. Recip-Compressor Frame Lubrication is part five of the Dresser-Rand Reciprocating Products 19-part training series.. Figure 11 -23 is a schematic of a typical system. The dividerblock system uses one or more lubricator pumps to supply a divider block, which then distributes the flow to each of the lubrication points. Reciprocating Compressors – Cylinder/Packing Lubrication System.
