How to adjust the striking frequency of excavator hydraulic breaker

　　In heavy industrial fields such as construction, mining and road construction, hydraulic breaker has become an indispensable engineering machinery equipment with its powerful crushing ability and efficient working performance. However, in order to give full play to the potential of hydraulic breaker, it is essential to accurately adjust its frequency. This article will introduce you to the frequency adjustment method of hydraulic breaker in detail to help you achieve a significant improvement in work efficiency.

　　1. Core elements: working pressure and flow of hydraulic system

　　The working principle of hydraulic breaker relies on the high-speed rotating hammer to impact and crush objects, and the hydraulic system is its core power source. By adjusting the working pressure and flow of the hydraulic system, we can directly affect the impact frequency of the breaker. When the working pressure and flow increase, the impact frequency of the breaker increases accordingly, which is suitable for rapid crushing of hard objects; conversely, reducing the working pressure and flow can slow down the impact frequency, which is suitable for fine crushing or protecting fragile objects.

　　2. Fine adjustment: valve core and backup pressure

　　In addition to adjusting the working pressure and flow of the hydraulic system, we can also change the diameter of the oil circuit by adjusting the valve core, so as to further fine-tune the flow rate of the hydraulic oil and the frequency of the breaker. In addition, as a key parameter in the hydraulic system, the backup pressure has an important impact on the impact frequency and stability of the breaker. According to actual needs, reasonable adjustment of the backup pressure can ensure that the breaker operates in the best condition.

　　3. Professional skills: piston stroke and power source adjustment

　　For some models of hydraulic breakers, we can also accurately control their impact frequency by adjusting the piston stroke or power source. During the specific operation, you need to first find the regulator on the right side of the breaker cylinder, use a wrench to remove the nut in front of the adjusting screw, and then change the stroke of the piston by rotating the adjusting screw. When the adjusting screw is rotated inward, the impact frequency will decrease; when it is rotated outward, the impact frequency will increase. This adjustment method requires certain professional knowledge and experience, and it is recommended to be carried out under the guidance of professionals.

　　4. Nitrogen volume adjustment: details that cannot be ignored

　　Hydraulic breakers are usually filled with nitrogen, and the amount of nitrogen will directly affect the frequency of the breaker. The more nitrogen, the greater the load, the slower the frequency; vice versa. Therefore, when adjusting the frequency of the breaker, we also need to consider the adjustment of the nitrogen volume. According to the equipment manual and actual needs, the amount of nitrogen can be reasonably adjusted to ensure that the breaker operates in the best working condition.

　　5. Maintenance and care: maintain optimal performance

　　In order to ensure that the hydraulic breaker can work continuously and stably, we also need to regularly maintain and care for the equipment. Check whether the cleanliness and viscosity of the hydraulic oil are appropriate to avoid problems such as blockage or leakage that affect the frequency; at the same time, check whether all parts are operating normally and replace severely worn parts in time. These measures can ensure that the breaker operates in the best condition, thereby improving work efficiency and extending the service life of the equipment.

　　In summary, the frequency adjustment of the hydraulic breaker is a complex but crucial process. By mastering the basic adjustment methods and making detailed adjustments for specific models, we can achieve precise control of the breaker frequency, thereby improving work efficiency and crushing effect. In future engineering construction, let us work together to promote the innovation and development of hydraulic breaker technology!
