Key technical indicators and details of current hydraulic breaker

● Transformation of main technical parameters to improve impact energy and efficiency and reduce gap 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 drill rods, good materials and excellent processing and heat treatment processes shall be provided to ensure their strength and toughness

● Cavitation, once the bushing of the drill rod 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.

● High pressure gas transmission interface: Krupp hydraulic breaker is suitable for high-pressure gas transmission connection ports with different connection sizes, which can be connected with high-pressure gas, so that the hydraulic breaker has the function of underwater operation.

● Self lubricating device. The automatic lubricating device is directly installed on the shell of the hydraulic hammer, which is extremely easy to operate and makes the consumption of lubricating oil the most economical.

● Low noise structure design, super dust-proof device, damping system and special wear-resistant materials

● The American montebate hydraulic breaker also has some other unique structures. The rotary joint at the oil inlet and outlet greatly improves the service life of the hose, and its built-in patented energy recovery valve can effectively reduce vibration and increase impact energy; The built-in special damping device can effectively reduce the vibration to the bearing machinery and greatly protect the working arm of the bearing machinery; Built in automatic pressure regulating device can realize automatic frequency conversion with gear and stepless automatic frequency conversion. Therefore, it can automatically adjust the impact energy and impact frequency according to the hardness of rock. When crushing hard rock, high impact energy and low frequency, and when crushing soft rock, low impact energy and high frequency; The structural design of three-stage large, medium and small pistons can realize the step-by-step transmission of impact energy, and can realize the maximum transmission of impact energy when the crushing force is most needed to break the rock.

● Atlas Copco's xprofile series products with X-type interface characteristics improve the penetration ability and the cooling performance of the hammer tip. Its self-repair ability can keep the hammer tip from deformation for a long time.
