Frame Lubrication System

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

Packing/cylinder lubrication can be provided from a forced feed compressor lube oil system. For very cold installations, immersion heaters and special lube oils must be considered. If the lube oil temperature gets too cold, the oil becomes too viscous and does not flow and lubricate properly.

Lubricated cylinders use a separate mechanical lubricator to force feed, in metered droplet form, a very precise amount of lubricant to specified points. This minimizes the amount of lubricant in the cylinder and allows a lubricant most compatible with the gas to be selected without compromising the frame lubrication system. Lubricant is fed to a point or points on the cylinder to service the piston rings and the packing when required. In a few cases, as in air compressors, the packing is lubricated from the crankcase. On some applications involving wet CO7 or H2S m the gas stream, special materials may be avoided if one of the lubrication points IS connected to the suction pulsation dampener. 

Chapter 3, which discussed various reciprocating compressors, stated that riiaii> reciprocators use a pressure-fed lubrication system for the frame bearings. This system is built into the crankcase in many applica tions. I he basics of these systems follow the fundamental criteria which will lie discussed with the fully separate system. The larger reciprocating compressors may use a separate frame lubrication system.

Steam turbines are used as drivers to turn pumps, compressors, and electric generators. High-pressure steam is directed into buckets designed to turn a rotor and provide rotational energy. Steam turbines serve the same function as electric motors. A typical motor is composed of stator windings, rotor and shaft, bearings and seals, conduit box, frame, fan, lubrication system, and shroud. Steam turbines and motors are two of the most popular devices used by industry as drivers. 

There is also a much more compact and low-cost option - based on the pump manufacturer concept . This concept has been tried and tested for decades in oil-lubricated rotary piston vacuum pumps - so why not in LRVPs. There is no need for extensive frame constructions for mounting system components. Costintensive pipes required for manufacturing previous units, as well as throughout the service life, are no longer required. Components can be retrofitted easily. 

The main bearings with seals are mounted onto the main frame in pillow blocks. When oil lubricated, the pillow blocks will be piped to an oil system, which will include a circulating pump, an oil reservoir and cooler with associated pressure, flow, and temperature instrumentation (see Section 2.2.4.4).
