Wall cavitation
| Diamond Glossary (алмазы и бриллианты - глоссарий терминологии) |
The development of enlarged sections in a borehole as the result of caving, erosive action of the circulated liquid, or erosion caused by drill rods rubbing against the borehole walls.

Cavitating disk device, английский
Дисковое устройство для испытания на кавитацию (состоит из диска с отверстиями, быстро вращающегося в жидкости и создающего коллапсирующие пузырьки, которые воздействуют на помещенные в устройстве опытные образцы)
Cavitation, английский
- Кавитация - явление, возникающее на плавнике на очень большой скорости (срыв потока), за чем неизбежен спин-аут (spin out)
- Formation of an air or vapor pocket (or bubble) due to lowering of pressure in a liquid, often as a result of a solid body, such as a propeller or piston, moving through the liquid; also, the pitting or wearing away of a solid surface as a result of the violent collapse of a vapor bubble. cavitation can occur in a hydraulic system as a result of low fluid levels that draw air into the fluid, producing tiny bubbles that expand followed by rapid implosion, causing metal erosion and eventual pump destruction.
- Кавитация
- Кавитация, образование пустот
- A phenomenon in the flow of water consisting in the formation and the collapse of cavities in water.
- The forming of a cavity
- The formation and collapse of air bubbles created by a ship’s propeller. this reduces effective thrust, creates noise detectible by an enemy, and may cause structural damage.
- The formation of a pocket (bubble) of air or vapor in a liquid, typically resulting from the swift movement of a solid object (such as a propeller or piston) through the liquid. also, the pitting and wearing away of metal or other solid surfaces caused by the collapse of air/vapor pockets in surrounding liquid.
- Describes the continous pumping of mud from surface-level mud tanks, down the drill pipe, out the drill bit nozzles, and through the gap between the drill pipe and the borehole to the surface. this movement carries rock cuttings via the shale shaker to the mud system.
Cavitation (hydraulics), английский
When the absolute pressure in a pump intake line is reduced below the vapor pressure of the liquid, the fluid may vaporize, or “boil”, or the dissolved air in the fluid may separate. in either case, as the bubbles go through the pump, they collapse or implode and damage the metal of the pump.

Cavitation cloud, английский

Cavitation corrosion, английский
Cavitation damage, английский
The pitting of concrete caused by implosion (collapse) of bubbles in flowing water.
Cavitation erosion, английский
- A material-damaging process which occurs as a result of vaporous cavitation. "cavitation" refers to the occurrence or formation of gas- or vapor- filled pockets in flowing liquids due to the hydrodynamic generation of low pressure (below atmospheric pressure). this damage results from the hammering action when cavitation bubbles implode in the flow stream. ultra-high pressures caused by the collapse of the vapor bubbles produce deformation, material failure and, finally, erosion of the surfaces.
- Loss of material due to the repeated formation and collapse of bubbles at the surface of an object in contact with a rapidly flowing liquid. glossary c 493 celsius (centigrade): temperature scale based on 273 k (0 °c = +32 °f) as the freezing point of water and 373 k (100 °c = 212 °f) as the boiling point of water at standard atmospheric pressure. a relative scale related to the kelvin scale (0 °c = 273.12 k; 1 °c = 1 k).

Gage diameter, английский
The diameter of an object as deter¬mined by measurement and/or size as compared to a standard.
Capillarity correction, английский
The deduction of a specific an¬gular value from the apparent angle, as indicated by the plane of the etch line in an acid-survey bottle, to correct for capillarity effects and thereby determine the true inclination angle of a borehole. proper values to be deducted from the apparent angles read on acid bottles differing in size may be determined by referring to charts, graphs, or tables prepared for that purpose. see capillarity-correction chart.
