The principle of operation is the same for all hammers.

The torque from the rotor is transmitted to the barrel shaft and a working tool mounted thereon. simultaneously, with the help of the rocker bearing, Popularly known as "drunk bearing", the torque is converted into a reciprocating motion, transmitting the impact impulse to the working tool.

All perforators Interskol assembled on one common chart and consist of the same units.

Conventionally, punchers Interskol composed of three blocks:

  1. impactor assembly gear unit.
  2. stator unit.
  3. Block power circuits and control.

Repair hammers Interskol should begin with the study of the instrument scheme, training tools and the workplace.

These blocks have these models have their own design features.

For ease of consideration, divide into groups represented drills.

  1. The first group will include perforators Interskol P-18, P-22, P-24, P-26, P-30.
  2. In the second group, consider dismantling hammers Interskol P-600 and P710.
