Usage of hydraulic crushing hammer

Explain the correct use of hydraulic crushing hammer.

1) Carefully read the operation manual of hydraulic crushing hammers to prevent damage to hydraulic crushing hammers and excavators and operate them effectively.

2) Before operation, check whether the bolts and connectors are loose, and whether there is leakage in the hydraulic pipeline.

3) Do not use a hydraulic hammer to peck holes in hard rock.

4) It is not allowed to operate the crushing hammer when the piston rod of the hydraulic cylinder is fully extended or fully contracted.

5) When the hydraulic hose vibrates violently, the operation of crushing hammer should be stopped and the pressure of accumulator should be checked.

6) To prevent interference between the arm of the excavator and the bit of the crushing hammer.

7) Do not immerse the crushing hammer in water except the drill bit.

8) Crushing hammer shall not be used as lifting device.

9) Crushing hammer shall not be operated on the crawler side of excavator.

10) When the hydraulic crushing hammer is connected with the hydraulic excavator or other engineering construction machinery, the working pressure and flow of the hydraulic system of the host must meet the technical parameter requirements of the hydraulic crushing hammer. The "P" port of the hydraulic crushing hammer is connected with the high pressure oil circuit of the host, and the "A" port is connected with the oil return circuit of the host.

11) The best hydraulic oil temperature of hydraulic crushing hammer is 50-60 degrees, and the highest temperature shall not exceed 80 degrees. Otherwise, the load of hydraulic crushing hammer should be reduced.

12) The working medium used by hydraulic crushing hammer can usually be consistent with the oil used in the hydraulic system of the host machine. It is recommended to use YB-N46 or YB-N68 anti-wear hydraulic oil in general areas, and yC-N46 or YC-N68 low-temperature hydraulic oil in cold areas. Hydraulic oil filtration accuracy is not less than 50micro; M.

13) New and repaired hydraulic crushing hammers must be re-filled with nitrogen at a pressure of 2.5, ±0.5MPa.

14) between the rod handle and the cylinder guide sleeve must be lubricated with calcium base grease or compound calcium base grease, and each shift is injected once.

15) When working, the hydraulic crushing hammer must first press the rod on the rock, and maintain a certain pressure before starting the crushing hammer, which is not allowed to start in the suspended state.

16) It is not allowed to use the hydraulic hammer as a crowbar to avoid breaking the drill bar.

17) Hydraulic crushing hammer and fiber rod should be perpendicular to the working face when used, in order to not produce radial force as the principle.

18) When the broken object has cracked or started to crack, the impact of the crushing hammer should be stopped immediately to avoid harmful "empty beating".

19) If the hydraulic crushing hammer wants to stop using for a long time, nitrogen should be discharged, and the oil inlet and outlet should be sealed, and the cutting iron should be stored in high temperature and -20 degrees below the environment.
