Now take the domestic S series Hydraulic Hammer as an example to illustrate the correct use of the 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) Before operation, check whether the bolts and connectors are loose, and whether there is leakage in the hydraulic pipeline.
3) Do not peck holes in hard rocks with hydraulic breakers.
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) Except for the drill bit, do not immerse the breaker in water.
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 rate of the main engine hydraulic system must meet the technical parameter requirements of the hydraulic breaker, and the “P” port of the hydraulic breaker is connected to the main engine high-pressure oil circuit Connect, the “A” port is connected with the return line of the main engine.
11) The best hydraulic oil temperature when the hydraulic breaker is working is 50-60 degrees, and the maximum shall 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 the same as 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 filtration accuracy of hydraulic oil is not less than 50 micro; 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) Calcium-based grease or compound calcium-based grease must be used for lubrication between the handle of the drill rod and the guide sleeve of the cylinder, and it should be refilled once per shift.
15) When the hydraulic breaker is working, the drill rod 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.
16) It is not allowed to use the hydraulic breaker as a crowbar to avoid breaking the drill rod.
17) When in use, the hydraulic breaker and the fiber rod should be perpendicular to the working surface, and the principle is that no radial force is generated.
18) When the crushed object has cracked or started to produce cracks, the impact of the breaker should be stopped immediately to avoid harmful “empty hits”.
19) If the hydraulic breaker is not to be used for a long time, the nitrogen should be exhausted, the inlet and outlet ports should be sealed, and the cut iron should be stored under high temperature and below -20 degrees.
