Third, the working efficiency of the hydraulic rock drill impact mechanism is reduced

Third, the working efficiency of the hydraulic rock drill impact mechanism is reduced
1) Insufficient oil or pressure
① Check the oil pressure on the pressure gauge, check the operation control mechanism and its system, if there is no problem with the latter, then the impact mechanism must be faulty, see fault (1);
2) The accumulator is faulty
② See fault (2);
3) Seal wear of the bit tail rebound absorber
③ Replace the rock drill on the drilling device, send the broken machine to the repair room for repair, replace the seals, such as oil leakage in the head, that is, the prediction of failure;
