How to Extend the Service Life of the Breaker's Vulnerable Parts

Since the breaker accessories are used in dynamic, any movable connection parts are easily damaged. But the correct use and operation can avoid occurrence, the correct use is as follows:

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

2. Do not peck holes in hard rocks with hydraulic breakers.

3. It is not allowed to operate the breaker under the condition that the piston rod of the hydraulic cylinder is fully extended or fully retracted.

4. When the hydraulic hose vibrates violently, stop the operation of the crusher and check the pressure of the accumulator.

5. Prevent interference between the boom of the excavator and the chisel of the breaker.

6. Except for the chisel, do not immerse the breaker in water.

7. Do not use the breaker as a lifting device.

8. Do not operate the breaker on the tire side of the excavator.

9. When the hydraulic breaker is installed and connected with the backhoe loader or other engineering construction machinery, the working pressure and flow rate of the hydraulic system of the main engine must meet the technical parameter requirements of the hydraulic breaker. The "P" port of the hydraulic breaker and the main engine high-pressure oil circuit Connect, the "0" port is connected to the return line of the main engine.

10. When the hydraulic breaker is working, the best hydraulic oil temperature is 50-60 degrees, and the maximum temperature should not exceed 80 degrees. Otherwise, the load of the hydraulic breaker should be reduced.

11. The working medium used by the hydraulic breaker can usually be the same as the oil used in the main engine 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 filtration accuracy of hydraulic oil is not less than 50μm.

12. New and repaired hydraulic breakers must be refilled with nitrogen when they are activated, and the pressure is 2.5, ±0.5MPa.

13. Calcium-based grease or compound calcium-based grease must be used for lubrication between the chisel handle and the cylinder guide sleeve, and it should be added once per shift.

14. When the hydraulic breaker is working, the chisel must be pressed on the rock first, and the breaker must be operated after maintaining a certain pressure. It is not allowed to start in the suspended state.

15. It is not allowed to use the hydraulic breaker as a crowbar to avoid breaking the chisel.

16. The hydraulic breaker and fiber rod should be perpendicular to the working surface when in use, and the principle of not generating radial force.

17. When the crushed object has cracked or started to produce cracks, the impact of the crusher should be stopped immediately to avoid harmful "empty hits".

18. If the hydraulic breaker is to be stopped for a long time, the nitrogen should be exhausted, and the oil inlet and outlet should be sealed. Do not store it under high temperature and below -20 degrees.
