The DSF forced-air cooling and the DS water cooling series electromagnetism turbulent flow gets on the brakes the electromagnetism turbulent flow braking is the adaptation uses in the sea and on the land petroleum drilling machine's new auxiliary brake, it uses the electromagnetic induction principle to carry on the non-attrition to apply the brake, in a big way, not vulnerable to have the moment of force, to use long-lived the life long, to operate the maintenance simple characteristic. May reduce main brake's using the electromagnetism turbulent flow brakes to wear large scale, the extension brake staple braking wheel hub's service life, reduces well driller's labor intensity, change exciting current adjusts the braking moment through the , controls the drill rod to release the speed. When the rotational speed drops to 5 revolution of/minute may reach the biggest moment of force 75%, can definitely satisfy the request which under the heavy load drills.
