the oil pump simply pumps constantly, and any excess pumped oil continuously escapes through a relief valve back into the sump. many bearings in high-cycle industrial operations need periodic lubrication and cleaning, and many require occasional adjustment, such as pre-load adjustment, to minimise the effects of wear.
pulsation is an important side effect of the peristaltic pump. the pulsation in a peristaltic pump is determined by many factors, such as: flow rate - higher flow rate is more pulsation; line length - long pipe lines is more pulsation; higher pump speed - higher rpm is more pulsation; specific gravity of the fluid - higher fluid density is more pulsation
a pump is a device that moves fluids, or sometimes slurries, by mechanical action. pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps. pumps operate by some mechanism, and consume energy to perform mechanical work moving the fluid. pumps operate via many energy sources, including manual operation, electricity, engines, or wind power, come in many sizes, from microscopic for use in medical applications t
hyperthermia, also known simply as overheating, is a condition where an individual's body temperature is elevated beyond normal due to failed thermoregulation.the person's body produces or absorbs more heat than it dissipates. when extreme temperature elevation occurs, it becomes a medical emergency requiring immediate treatment to prevent disability or death.

the oil is cooled by the outside of the tank in small ratings, and by an air-cooled radiator in larger ratings. where a higher rating is required, or where the transformer is in a building or underground, oil pumps circulate the oil, and an oil-to-water heat exchanger may also be used.
in electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. the most common type of switch is an electromechanical device consisting of one or more sets of movable electrical contacts connected to external circuits.
nominator's comments: a former int/r, this year's event was listed by cnn as the second 'must see' sporting event of 2012 after the olympic games. attendance placed this year's game as the 5th most attended domestic outdoor sporting event of all time. --ra 18:56, 30 september 2012 utc support per nom, but only once there is more of an update for the final's replay.
