n: an air- or inert gas-filled device that minimises pressure surges in the output line of a mud pump. Sometimes called a surge dampener.

a device in the line filled with gas that may reduce the surges of pressure pulsation or flow slugging.

n: refer to vibration dampender

n: see pulsation dampener.

n: 1. any gas or liquidcharged, chambered device that minimizes periodic increases and decreases in pressure (as from a mud pump). 2. a device used to reduce pressure pulsations in a flowing stream.

n: 1. a kinds of device that absorbs vibration, which removes instantaneous rhythmic wave propagation when reciprocal pump enforces to fluid. 2. for protecting the pressure gauge from continued vibration, fine screen plate fixed on the slim tube of contin

n: A kind of safety relief expansion joint ,which be used to decrease the vibration.



a mechanical dampener above a perforating gun that attenuates some of the acceleration force created by firing the gun.

n: a vibration dampener.

n: a steel chamber with an air-charged rubber bladder (or diaphragm) inside that is mounted on a mud pumps intake (suction) line. It absorbs the impact that occurs when the smooth flow of fluid in the suction line coming out of the suction tank meets the intermittent flow caused by fast moving pump pistons.

n: see dampener.

n: 1. a device, positioned in the drill stem between the bit and the drill collars, that absorbs impact loads and vibration from the up-and-down motion of the drill stem. Vibration dampeners are designed to transmit torque while absorbing reciprocative loads that decrease the efficiency of the drill bit. Also called a Shock Sub. 2. a device affixed to an engine crankshaft to minimize stresses that result from torsional vibration of the crankshaft. vibration error n: the maximum change in operating output, at any measured value within a specific range, when vibration levels of specified amplitude and range or frequencies are applied to the transducer along specified axes.

n: The tool can decrease the vertical and rotary shock vibration coming from bottomhole .
