Aircraft maintenance lubrication equipment is used as pumping equipment to apply controlled or metered amounts of lubricant. Applications include compressed air lines, dies, chains, cables, bearings, gears, pumps, spindles and other rotating or moving machine components. Important parameters to consider when specifying such equipment are capacity, lubrication flow rate, operating pressure, and maximum operating temperature. The flow rate is the rate at which the lubrication is dispensed. Operating pressure refers to the maximum allowable pressure that the lubricator can be operated if pneumatically or hydraulically-operated lubricators. Gravity-fed lubricators operate at atmospheric pressure. Maximum operating temperature is the full-required range of ambient operating temperature.
Media choices include dry lubricant, grease, oil, and air and oil. Operation or actuation mechanisms include electric, electrochemical, gravity, hydraulic, manual, mechanical, and pneumatic. Constant level equipment is designed to keep a constant level of lubrication fluid in a bearing housing or gearbox. Full flow lubrication equipment dispenses un-metered liquid lubricant. However, closed system equipment is the future.
Aircraft maintenance lubrication equipment and the environment.
Macnaught greasing products, for example, are greasing products made with full attention to efficiency practices, waste minimisation, pollution prevention, legal requirements and environmental objectives.
Used lubricants may contain materials that are harmful to the environment. Lubricant conservation and used oil reclamation, reprocessing, and disposal, the concepts of the environmental compatibility biodegradability and toxicity of the lubricants are the best tools to restrain the ever-increasing use of lubricants. Lubricants with extended useful life are being developed and this also translates into cost savings.
