● Transformation of main technical parameters to improve impact energy and efficiency and reduce gas leakage.

● Improve energy utilization and production efficiency. For example, frequency conversion device and automatic pressure regulating device are used to adjust different frequencies and impact energy under different working conditions.

● Requirements for materials to improve the wear resistance and reliability of materials

● According to the requirements of body structure, the appropriate hydraulic breaker shall be selected according to the operation stability of excavator and other machinery, the working pressure and power consumption of hydraulic circuit of working device.

● For the strength and toughness of chisels, good materials and excellent processing and heat treatment processes shall be provided to ensure their strength and toughness.

● Cavitation, once the bushing of the chisel is excessively worn, the drill rod will form a deflection angle, and the piston will jam when the piston strikes the surface of the drill rod. At the moment of being stuck, the sudden stop of the piston will cause the movement and fracture of the sealing oil column on the piston surface, produce zero oil pressure, make the oil evaporate continuously, and finally produce cavitation and damage the piston.

● The problem of connecting frame, The connecting frame is generally of welded structure. The bad working environment of hydraulic breaker will make the weld bear huge force. In order to reduce vibration, the hydraulic breaker and the connecting frame shall be elastically connected, and the hydraulic breaker and the carrier shall be closely connected to improve the strike stability.
