Pump, английский
- Pompe
- A device which converts mechanical force and motion into hydraulic fluid power.
- To excite the lasing medium. pumping addition of energy (thermal, electrical, or optical) into the atomic population of the laser medium, necessary to produce a state of population inversion.
- A device or machine that compresses and/or transports fluids, usually by pressure or suction, or both; may be used to remove water from a construction site or to convey water from one elevation to another.
- A machine which forces liquids or air into or out of something verb to force liquid or air along a tube the heart pumps blood round the body. the nurses tried to pump the poison out of the stomach.
- Помпа, насос
- A well-known machine used for drawing water from the sea, or discharging it from the ship`s pump-well.—chain-pump, consists of a long chain, equipped with a sufficient number of metal discs armed with leather, fitting the cylinders closely, and placed at proper distances, which, working upon two wheels, one above deck and the other below, in the bottom of the hold, passes downward through a copper or wooden tube, and returning upward through another, continuously lifts portions of water. it is worked by a long winch-handle, at which several men may be employed at once; and it thus discharges more water in a given time than the common pump, and with less labour.—main pumps. the largest pumps in a ship, close to the main-mast, in contradistinction to bilge pumps, which are smaller, and intended to raise the water from the bilges when
- A device for moving, forcing, or lifting liquids; also, the act or process of moving such liquids.
- Мужская бальная туфля (обыкн. лакированная)

Pump capacity, английский
- The volume of fluid, at a specified pressure, that a pump can transfer or lift when powered by an engine or motor of any given horse¬power. pump capacity also depends on fluid vis¬cosity, pump condition, line friction, etc.
- Measured in gallons per minute or similar measurements of flow; along with thrust/pullback and torque, one of three measurements typically used to describe and classify drill rigs and their suitability to successfully perform an installation.

Pump cup, английский
Pump depletion, английский
Reduction in the transmitted pump power in a laser or nonlinear conversion device
Pump disc, английский
Pump disk. = cup leather, q.v.
Pump discharge, английский
- The port through which a fluid is ejected as it is acted upon by the pump.
- The hose or length of pipe transferring a fluid from a pump after the fluid has been acted on by the pump to the point where fluid is to be used or discarded.

Pure air supply, английский
In leak testing, air that has been cleaned of halogen contamination by means of an activated charcoal filter. this term is sometimes also used to describe any nonreactive gas, such as nitrogen, that contains no halogen contamination and to which the leak detector is not sensitive. q
Proportioning probe, английский
Probe that can vary the tracer gas concentration in the sample at the sensor, typically by mixing pure air with sample gas from the probe inlet port. ratios of mixture between 100 percent pure air (obtained from an outdoors source or by filtering ambient air through charcoal) and 100 percent leak sample gas are attainable without great changes in total flow from the probe. the proportioning probe used in halogen leak testing lets the user operate in an atmosphere with up to 1000 ?l/l tracer gas background contamination. it proportions the amount of atmosphere allowed to enter the probe with its own (recirculating) fresh air supply. pump, adsorption: pump that creates a vacuum by collecting gas on the interior surfaces of the pump. pressures of 2 pa (20 ?bar) are readily attained. the pump has a finite capacity but may be regenerated for additional use. see also backstreaming; baffle. pump, cryogenic: pump that condenses chamber gas on a cold surface of 4 to 80 k (–269 to –194 °c). cooling is provided by liquid gas such as liquid helium or by refrigeration. see also backstreaming; baffle. 748 glossary p-r pump, diffusion: high vacuum pump with no moving mechanical parts that uses a vapor jet to sweep gas from the vacuum chamber and achieve pressures as low as 1 npa (10 ptorr). pump, displacement: mechanical pump that physically sweeps gas out of a volume and creates a vacuum. rotary piston and rotary vane pumps are two examples. a displacement pump can achieve pressures in the 0.1 to 1.0 pa (10 to 1 mtorr) range. see also backstreaming; baffle. pump, fore: mechanical pump in a helium mass spectrometer that performs initial evacuation of a system to a pressure of 0.1 pa and then accepts the exhaust from the high vacuum pump such as a diffusion pump. the forepump lowers pressure to less than 10 kpa into which the diffusion pump can exhaust its gas. pump, ion: pump that combines electric and magnetic fields to ionize gas and trap the gas inside the pump, thus removing it from the vacuum chamber. see also ionization gauge. pump, mechanical: mechanical device with pumping fluid and seals that physically removes a portion of the gas from a system with each revolution of the armature. a mechanical pump can pump a chamber down to about 0.1 pa (0.75 mtorr). see also gas ballast; roots blower. pump, sorption: pump consisting of a sieve and liquid nitrogen with ability to pump to 0.1 pa (1 mtorr). pump, turbomolecular: molecular turbine that drives gas out of a vacuum chamber, achieving a high vacuum pressure in the 10 npa (0.1 ntorr) range.
