(The brass on the outside of a modern instrument is lacquered or plated to prevent corrosion.) The oil also completes the seal between the valve casing and the piston or rotor. Although a clean and unoiled valve of a well maintained instrument should move without unusual force, the inside of a musical instrument is a very inhospitable ...
Oil analysis (OA) is the laboratory analysis of a lubricant's properties, suspended contaminants, and wear debris. OA is performed during routine predictive maintenance to provide meaningful and accurate information on lubricant and machine condition. By tracking oil analysis sample results over the life of a particular machine, trends can be ...
Predictive maintenance techniques are designed to help determine the condition of in-service equipment in order to estimate when maintenance should be performed. This approach claims more cost savings over routine or time-based preventive maintenance, because tasks are performed only when warranted. Thus, it is regarded as condition-based ...
A smaller instrument or finger may be introduced gradually to minimize the discomfort that some may feel. Massagers may be used with or without a condom; however, because of the bacteria found in the rectum, if a condom is not used, it is very important to clean the tool with soap before use in another orifice or by a partner.
The appropriate lubricant for an automatic lubrication system can be determined using a Lincoln ventmeter. Factors such as the lubricant consistency, the diameter and length of the feed line and the operating temperature are taken into account. [7] The lubricant, be it oil or grease, is dispensed from a reservoir.
Cutting fluid is a type of coolant and lubricant designed specifically for metalworking processes, such as machining and stamping. There are various kinds of cutting fluids, which include oils, oil-water emulsions , pastes, gels, aerosols (mists), and air or other gases.
An instrumentalist should keep in mind how to play their instrument carefully so that they can preserve the integrity of the instrument. That being stated, each musician performs with an instrument differently, creating their own personality and take on the capabilities of that particular instrument (ex. Louis Armstrong and his trumpet).
The oil pressure generated in most engines should be about 10 psi per every 1000 revolutions per minute (rpm), peaking around 55-65 psi. [2] Local pressure (at the crankshaft journal and bearing) is far higher than the 50, 60 psi &c. set by the pump's relief valve, and will reach hundreds of psi.
