Hydraulic breakers are referred to as “crushers” or “crushers”. The power source of hydraulic breakers is the pressure provided by excavators, loaders or pumping stations. It can crush stones and rocks more effectively during construction and improve work. effectiveness. How to use hydraulic breakers correctly? 
Hydraulic breaker
Precautions for the correct use of hydraulic breakers:
1) Read the operating manual of the hydraulic breaker carefully to prevent damage to the hydraulic breakers and excavators and to operate them effectively.
2) Check the bolts and connectors for looseness before operation and whether the hydraulic lines are leaking.
3) Do not use a hydraulic breaker to burrow holes on hard rock.
4) Do not operate the breaker under full or full contraction of the piston rod of the hydraulic cylinder.
5) When the hydraulic hose is subjected to severe vibration, 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 for the drill.
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 engineering construction machinery, the working pressure and flow rate of the main hydraulic system must meet the technical parameters of the hydraulic breaker. The “P” port of the hydraulic breaker and the high-pressure oil passage of the main engine Connection, "A" port is connected with the main engine return line.
11) The optimum hydraulic oil temperature for hydraulic breakers is 50-60 degrees, and the maximum temperature should not exceed 80 degrees. Otherwise, the load on the hydraulic breaker should be reduced.
12) The working properties of the hydraulic breaker can be consistent with the oil used in the main engine hydraulic system. YB-N46 or YB-N68 anti-wear hydraulic oil is recommended for general use, and YC-N46 or YC-N68 low temperature hydraulic oil for cold areas. Hydraulic oil filtration accuracy is not less than 50micro; m.
13) New and repaired hydraulic breakers must be refilled with nitrogen at a pressure of 2.5 and ±0.5 MPa.
14) The drill stem handle and the cylinder guide sleeve must be lubricated with calcium-based grease or composite calcium-based grease, and each shift should be filled once.
15) When the hydraulic breaker is working, the drill rod must be pressed on the rock first, and the hammer must be started after a certain pressure is maintained. 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) The hydraulic breaker and the fiber rod should be perpendicular to the working surface when in use, so as not to generate radial force.
18) When the broken object has cracked or cracks begin to occur, the impact of the breaker should be stopped immediately to avoid harmful “running”.
19) If the hydraulic breaker is to be used for a long time, the nitrogen should be exhausted, and the inlet and outlet ports should be sealed. The iron should be stored under high temperature and below -20 degrees.
