1. Structure of breaker hammer
The main work of the breaker hammer is composed of cylinder, piston rod, drill rod, reversing valve, accumulator, oil seal assembly and other parts.
2. Working principle of breaker hammer
The kinetic energy of the hydraulic oil inlet + the kinetic energy of the upper accumulator pushes the cylinder rod upward to compress the nitrogen chamber. After pushing to the highest point, the reversing valve switches direction. The kinetic energy of the hydraulic oil inlet + the kinetic energy of nitrogen compression pushes the cylinder rod downward quickly to knock the drill rod to complete the crushing work.
3. Use the breaker correctly
1. The drill rod is perpendicular to the striking surface, and the drill rod is compacted (hitting at an angle can easily cause the drill rod to break and damage the cylinder body, and empty hitting without compacting the drill rod can cause damage to the cylinder body)
2. The engine should be warmed up for ten minutes before crushing operation, especially in winter, which will help the operation go smoothly; before crushing, visually check each oil pipe for oil leakage. Oil leakage should be dealt with in time. Check the breaker hammer oil seal for oil leakage. If there is oil leakage, the oil seal must be replaced in time, otherwise dust will enter the piston and wear it.
3. Do not use the breaker to push heavy objects or large rocks, as this may cause the breaker bracket to break.
4. Do not use the drill rod to pry or shake, as this may cause the drill rod to break.
5. Do not hit the same place continuously for more than 1 minute, otherwise it will easily cause excessive wear of the drill rod. You should change the location of the blow. Larger and harder stones should be broken at the edge, because the edge is easier to break.
6. Insufficient blow operation during crushing. Do not drop the breaker hammer on hard rocks. The breaker hammer and machine structural parts will be damaged due to excessive vibration. Improper engine speed will cause insufficient blow force and damage the piston engine valve.
7. Do not carry out crushing operations in water or muddy ground. Water can easily invade the piston, causing the piston to rust. Mud and dust can easily accumulate in the drill rod chamber and accelerate the wear and tear of the breaker hammer.
8. Do not perform impact operations when the bucket, forearm, and boom cylinders of the machine are fully extended or fully retracted. This may cause the impact vibration to reverberate into the cylinder block and cause the cylinder rod to break.
9. Do not lift heavy objects with a breaker or drill rod. This may cause damage to the machine parts or drill rod, and may also cause the risk of heavy objects falling off.
10. When the breaker is not used for a long time, the drill rod must be fully pushed into the breaker to push the piston and cylinder rod into the piston to prevent the cylinder rod from being exposed to the air and being corroded and damaged.
11. Parts should to be replaced regularly:
The drill rod and excessive wear need to be replaced in time, and the drill rod pin must also be replaced at the same time. Otherwise, the drill rod is too loose and will accelerate the loss of the drill rod;
4. Maintenance recommendations for breakers
The oil seal or oil seal leaks or needs to be replaced in time within 6 months, otherwise foreign matter will enter the system and cause piston wear and contamination damage to the excavator hydraulic system;
Through-bolts, nuts, shell bolts, hydraulic pipes, and bushings must be inspected regularly. If any loss is found, they need to be replaced in time, otherwise it may easily cause a major failure.
When using the hydraulic oil return filter and common breaker operations, the oil return filter needs to be replaced every 250 hours;
When working with hydraulic oil and commonly used breaker hammers, the entire vehicle's hydraulic oil needs to be replaced every 600-1000 hours, otherwise the machine's hydraulic system is easily damaged due to contamination of the hydraulic system;
