2nd, the ballistic work of the impactor is the characteristic that magnet homopolar-repulsion (same sex repulsion) is utilized by a pair of of permanent magnet, is compressed
Clearance distance between the two poles of the earth, repulsive force increase sharply, and block stamp 15 obtains ballistic work, energy storage and release under the action of repulsive force
Two magnet of process there is no direct Mechanical Contact, avoid use during spring energy-storage spring circulation compression caused by machinery
Fatigue damage, so as to be effectively improved the life and reliability of whole impactor.
3rd, downhole electrical motor 2 provides power for whole impactor, and impactor is adjusted by adjusting the rotating speed of downhole electrical motor 2
Frequency of impact, frequency of impact are stablized, from the influence of drilling fluid system change.
