n: the motion a bit makes when it does not rotate around its centre but instead drills with a spiral motion. It usually occurs to a bit drilling in a soft or medium soft formation when the driller does not apply enough weight or does not rotate the bit fast enough. A whirling bit drills an overgauge hole (a hole larger than the diameter of the bit) and causes the bit to wear abnormally.

n: The group setting of whirling current separator groups and vibrosieve.

n: One of the abnormal mode of operation for whirling current separator. Its base flow presents like a rope.

n: whirling current separator that dispose of 7 to 10mm solide in the drilling fluid.

n: the effluent of a cone-shaped centrifuge that passes up the inside of the cone and leaves through the vortex finder.

n: 1 the volume of fluid return from the mouth above the pump input , the phenomenonof fluid automatic flowing out. 2. the fluid derived from the overflow pipe of whirling current separator.

n: the tube that entries the output overflow of two or more hydraulic whirling current separator .

n: the assembly tube that one or more overflow of hydraulic whirling curreent separator or one or more overflow of mainfold is directionally distributed.

n: the outflow mouth of lower solids content in hydraulic whirling current separator and centrifuge.

n: 1. a whirling mass, e.g., a whirlpool. 2. in gas and liquid measurement, a rotational-flow zone that forms on alternate sides of a non-streamlined body placed in a high-velocity flowing stream.

n: the short pipe in a coneshaped separator that extends down into the cone body from the top and that forces the whirling stream of material to start downward toward the small end of the cone body.

n: A hollow tubular in the center of sleeve chuck of hydraulic cyclone.
