With the dynamic changes in society, my country's product upgrading technology is developing rapidly. Among them, the technology of excavators can not be upgraded, the application of breaking hammers is constantly improving, and hydraulic breaking hammer manufacturers are also constantly developing and upgrading. Large breaking hammers Appeared. The following characteristics belong to the large breaker:
Wear faster:
Due to various factors such as new machined parts, installation, adjustment, etc., the friction surface is not smooth, the contact area of the mating surface is small, and the surface pressure is uneven. During the operation of the equipment, the uneven parts on the surface of the parts are inserted and rubbed against each other. The worn metal fragments continue to participate in the friction as wear-resistant materials, which accelerates the wear of the matching surface of the parts. Therefore, during the running-in period, the parts (especially the matching surface) are easy to wear, and the wear speed is faster. At this time, If overloaded, it may cause component damage and early failure.
Poor lubrication:
Because the assembly gap of the newly assembled parts of the hydraulic breaker is relatively small, due to factors such as assembly, the uniformity of the assembly gap cannot be guaranteed, and the lubricating oil (lubricating grease) is not easy to produce a uniform oil film on the friction surface to avoid wear. Thereby reducing the lubrication efficiency, Causes early abnormal wear of parts. Very serious friction surface scratches or bites, resulting in common failures.
loose:
The newly processed and assembled parts have deviations in geometric structure and matching specifications. In the initial stage of use, due to alternating loads such as shock and vibration, as well as various factors such as heat and deformation, coupled with factors such as excessive wear and tear, it is easy to cause the original The standard parts are loose.
Many wrong operations:
Due to insufficient grasp of the structure and characteristics of hydraulic breaker equipment (especially for new operators), it is easy to cause common failures due to incorrect operation, and even lead to equipment accidents.
