Bottom-hole pressure
| Diamond Glossary (алмазы и бриллианты - глоссарий терминологии) |
- The load, expressed in pounds or tons, applied to a bit or other cutting tool while drilling.
- The pressure, expressed in pounds per square inch (p.s.i), produced at the bottom of a borehole by the weight of the column of circulation or other liquid in a borehole.
- The pressure, expressed in pounds per square inch (p.s.i.), exerted by gas or liquids ejected from the rocks at or near the bottom of a drill hole.

Pressure altimeter, английский
An aneroid barometer with a scale graduated in altitude instead of pressure units.
Pressure altitude, английский
- Барометрическая высота
- The indicated altitude when an altimeter is set to 1013 hpa (29.92 inhg us and canada).
Pressure anemometer, английский
Pressure angle (gears), английский
Angle between the line of action and a line tangent to both pitch circles. this angle remains constant with involute form teeth at any point in the contact path. common pressure angles are 14.5° and 20°; when stronger teeth are needed, larger angles are used. pressure angles increase with center distance. pressure, atmospheric: see normal pressure.
Pressure arc welding, английский
Pressure arch, английский
Circulation, английский
- Циркуляция
- Circulation (of the blood) movement of blood around the body from the heart through the arteries to the capillaries and back to the heart through the veins she has poor circulation in her legs. rub your hands to get the circulation going. comment: blood circulates around the body, carrying oxygen from the lungs and nutrients from the liver through the arteries and capillaries to the tissues. the capillaries exchange the oxygen for waste matter such as carbon dioxide which is taken back to the lungs to be expelled. at the same time the blood obtains more oxygen in the lungs to be taken to the tissues. the circulation pattern is as follows: blood returns through the veins to the right atrium of the heart. from there it is pumped through the right ventricle into the pulmonary artery, and then into the lungs. from the lungs it returns through the pulmonary veins to the left atrium of the heart and is pumped from there through the left ventricle into the aorta and from the aorta into the other arteries.
- The passing of any liquid or gas to the end of the drill string and back to the surface in the process of drilling a borehole.
- The movement of air currents through mine openings.
- An item that is communicated to team members on a group work site, and that supports confirmation and tracking of which team members have viewed it. cisc (n)
- Caused by quick changes in pressure, cavitation is the creation of vapor cavities within a low-pressure liquid. cavitation can cause severe wear through cyclic stress on metal surfaces as they implode.

Break in, английский
- To start drilling operations with a new bit by rotating the bit slowly under a light load for a short period of time before full speed and load are applied to the bit.
- To round off sharp corners and points on a carbon through use and repeated resetting in a bit.
- To operate any new machine at less than full capacity for a short time.
Boring head, английский
- The part of a drill machine more commonly called swivel head by persons associated with the diamond-drilling industry. see swivel head.
