Lubrication procedures

Despite overwhelming evidence suggesting that poor machinery lubrication spells trouble for the plant, most organizations lack clearly defined written procedures for performing basic lubrication tasks. The following outlines reasons why lubrication procedures are important elements of a proper lubrication procedure. ... 

Electronic. Prepare lubrication procedures in an electronic form, preferably on a company-wide intranet, or onto an internet account for those who are moving toward web-based application support. When the procedures are electronic, they can be updated globally, attached to work orders, and linked to like... 

There are a number of important areas that should be covered by lubrication procedures. These include the following ... 

Lubrication Procedures and Documentation Development of lubrication procedures consistent with industry best practices must include documentation and training. 

Accessorizing Machinery for Precision Lubrication Even the best lubrication procedures and PMs are of little value if the equipment is not properly equipped with hardware that enable their use. 

Provide training in effective plant lubrication procedures and techniques. The lubricator, maintenance personnel, and maintenance supervisors should attend. 

It is noteworthy, however, that traces of sulfur can have beneficial effects on the anti-wear resistance of fuel injection pumps. It is thus undesirable to reduce the sulfur content to extremely low values unless additives having lubricating qualities are added. Independently from total sulfur content, the presence of mercaptans that are particularly aggressive towards certain metal or synthetic parts is strictly controlled. The mercaptan content is thereby limited to 0.002% (20 ppm) maximum. The analysis is performed chemically in accordance to the NF M 07-022 or ASTM D 3227 procedures.

To produce unsintered tape by paste extmsion, the fine powder is lubricated and preformed according to the procedure described above. The preform is extmded in the form of rods, which are calendered on hot roUs to the desired width and thickness (109,110). 

Color Coding. New machinery and equipment must conform to OSHA standards and OEM specifications for color coding. Color coding can also help to speed up maintenance procedures. Examples include lubrication information, orientation, timing marks, torque requirements, etc. 

The Federal Trade Commission has aimounced a rule, effective November 30, 1995, that sets test procedures and labeling standards for recycled oil used as engine lubricating oil (35). The test procedures used are those contained in the Engine Oil Licensing and Certification System of the American Petroleum Institute (API) (36). The rule states in effect that if recycled oils meet the requirements of the API Certification System, such oils ate substantially equivalent to new oil for use as engine oil. This federal rule preempts certain state recycled oil rules (35). 

Use chemical interaction matrices to identify potential incompatibilities between combinations of materials (not just binary reactions) and interactions with cleaning solvents, heat transfer fluids and other utilities, equipment lubricants, scrubbing media, materials of construction, etc. Implement management of change procedures for changes in design, operation, equipment and chemistry. 

Operating experience has proven that unless a continuous program of required lubrication is followed, even the most well-designed units are sure to fail. A proper lubrication management program must incorporate a monthly lubrication schedule, an evaluation of new lubrication products, and supervision to ensure the prescribed procedures are carried out by maintenance personnel. 

In the event of failures due to lubrication problems, the failures should be thoroughly analyzed to determine if they were indeed caused by lubricant failure or incorrect maintenance procedures. Once the problem has been isolated, corrective action can be initiated to prevent subsequent similar failures—whether it requires changing lubricants or procedures. 

Mechanical testing of the non-lubricated helical-lobe compressors is modified from the previously described lest. For example, API 619 only requires a two-hour mechanical run. The procedures and monitoring requirements are generally the same as previously described. A run comparable to the overspeed run is the heat run. The compressor is run on air at the maximum allowable speed, and the discharge temperature is allowed to stabilize at a value 20°F higher than the rated discharge temperature. The compressor is then run for 30 minutes. 

Interactions refers to any jobs, tasks, or operations carried out by people who could directly or indirectly cause the hazard to be released. Direct interactions with the plant might involve breaking open pipework, opening reactors, etc. Indirect interactions would include remote activation of valves from a control room, or the performance of maintenance on critical plant items. Errors that might occur during these interactions could allow the harm potential to be released. This could occur directly (for example, a worker could be overcome by a chlorine release if an incorrect valve line-up was made) or indirectly (for example, if a pump bearing in a critical cooling circuit was not lubricated, as in the example in Chapter 1). The procedure as described above... 

Final Preparation. Remove all seizings. Apply lubricant to rope adjacent to socket to replace lubricant removed by socketing procedure. Socket is then ready for service. 

The specific installation procedure is dependent on the type and mounting configuration of the coupling. However, common elements of all coupling installations include spacing, bolting, lubrication, and the use of matching parts. The sections to follow discuss these installation elements. 

The velocity analysis is of great important for a lubrication theory, which will lay the foundation for further processes, to obtain the flux, the pressure distribution, the load and the friction, etc. As shown before, however, the present model requires a complex procedure to achieve the results. Thus, it can be regarded as a more purely scientihc one," i.e., there is a long way to the success of predictive ability. For a practical purpose, from an engineering point of view, some simplifications should be conducted in an attempt to get the parameters of interest.
