Now take Guanghan breaker as an example to explain the correct use of hydraulic breaker.
1. Read the operating manual of the hydraulic breaker carefully to prevent damage to the hydraulic breaker and excavator, and operate them effectively.
2. Check whether the bolts and connectors are loose before operation, and whether there is leakage in the hydraulic pipeline.
3. Do not use the hydraulic breaker to peck holes in hard rocks.
4. Do not operate the breaker with the piston rod of the hydraulic cylinder fully extended or fully retracted.
5. When the hydraulic hose vibrates violently, stop the operation of the breaker and check the pressure of the accumulator.
6. Prevent interference between the boom of the excavator and the drill bit of the breaker.
7. Do not immerse the breaker in water except the drill bit.
8. Do not use the breaker as a lifting device.
9. Do not operate the breaker on the crawler side of the excavator.
10. When the hydraulic breaker is installed and connected with the hydraulic excavator or other construction machinery, the working pressure and flow of the main hydraulic system must meet the technical parameter requirements of the hydraulic breaker. The "P" port of the hydraulic breaker is connected to the high-pressure oil circuit of the main machine, and the "A" port is connected to the return oil circuit of the main machine.
11. The optimal hydraulic oil temperature of the hydraulic breaker is 50-60 degrees, and the maximum should not exceed 80 degrees. Otherwise, the load of the hydraulic breaker should be reduced.
12. The working medium used by the hydraulic breaker can usually be consistent with the oil used in the main hydraulic system. 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. The hydraulic oil filtration accuracy is not less than 50micro;m.
13. New and repaired hydraulic breakers must be refilled with nitrogen when they are activated, and the pressure is 2.5, ±0.5MPa.
14. The handle of the drill rod and the guide sleeve of the cylinder must be lubricated with calcium-based grease or composite calcium-based grease, and it should be refilled once every shift.
15. When the hydraulic breaker is working, the drill rod must be pressed on the rock first, and a certain pressure must be maintained before the breaker is started. It is not allowed to start in a suspended state.
16. It is not allowed to use the hydraulic breaker as a pry bar to avoid breaking the drill rod.
17. When using, the hydraulic breaker and the fiber rod should be perpendicular to the working surface, and the principle is not to generate radial force.
18. When the object to be broken has broken or cracks have begun to appear, the impact of the breaker should be stopped immediately to avoid harmful "empty hits".
19. If the hydraulic breaker is to be stopped for a long time, the nitrogen should be exhausted, and the inlet and outlet oil ports should be sealed. The cut iron should be stored in an environment of high temperature and below -20 degrees.
