Field tests are carried out, intermediate results are obtained: the operating time of the hydraulic impact mechanism was 430 hours, the hydraulic impact mechanism is under revision, there is no damage to the protective coating of the intermediate case.
Detailed:
- Equipment: The cylinder, is applied as a part of hydraulic shock mechanisms.
- Operating conditions of a detail: Hydroabrasive environment.
- Customer's problem: An initial covering – galvanic chrome. As a result of influence of the liquid abrasive environment, drilling mud of various aggression, subfilm corrosion, peeling appeared.
