Circulating oil system
| Глоссарий терминов смазочных материалов |
A lubrication system in which the fluid that has passed through a bearing or a group of bearings is recirculated by a pump. system components may include settling tanks, filters, pumps, heat exchangers, etc. pressure is usually controlled by a pressure control valve.

Lubrication, английский
- The control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact. the lubricant used can be a fluid, solid, or plastic substance.
- Смазка
- On no account should oil be used to lubricate pin-tumbler cylinders. graphite is the conventional lubricant for this mechanism.
- Смазка (действие)
- The act of injecting a fluid, normally bentonite and/or polymers, to reduce the skin friction and jacking forces on the jacking pipe during installation. the fluid fills the annular space.
- Means of reducing friction either around a pipe being jacked or a shaft being sunk into the ground.
- The control of friction and wear between two moving, touching surfaces by placing a friction-reducing substance between them.
- Control of friction and wear by the introduction of a friction reducing film between moving surfaces in contact. the film may be fluid, solid or plastic.
- Reduction of friction or wear between two load-bearing surfaces by the application of a lubricant; includes boundary lubrication (thin or interrupted fluid film, especially bearings where wear occurs); mixed film, where some liquid pools support the load; elastohydrodynamic (high-pressure loads increase the lubricant’s viscosity and load-carrying capacity, especially in gears); hydrodynamic (a thick fluid film lubrication, especially in journal bearings) and hydrostatic (external pump pressure used to form a thick fluid film, as in start-up of journal bearings).

Clay thickener, английский
Inorganic, non-melting grease thickener, commonly activated bentonite clay.
Circular pitch (gears), английский
Distance measured on the pitch circle between a point on the face of one tooth and the same point on the adjacent tooth; equal to pi divided by the diametral pitch.
