Analysis of common faults of hydraulic breaker: A complete guide to continuity, impact force and impact frequency

　　In the field of engineering machinery, hydraulic breaker has become a powerful assistant for many construction projects with its efficient and powerful crushing ability. However, with long-term use and complex working environment, hydraulic breaker will inevitably encounter various faults, affecting its performance and efficiency. This article will analyze the three common faults of hydraulic breaker - reduced continuity, reduced impact force and insufficient impact frequency, and provide practical solutions to help you easily cope with challenges and ensure smooth construction.

　　1. Reduced continuity of hydraulic breaker: unobstructed oil circuit is the key

　　The poor continuity of hydraulic breaker is often caused by oil circuit blockage or failure. When the oil circuit is blocked by impurities, high-pressure oil cannot flow smoothly, causing the breaker to move slowly. In addition, problems such as wrong connection of oil pipes, insufficient pressure value, wrong direction of reversing valve, piston stuck and stop valve failure can also cause insufficient impact force or impact stagnation. Therefore, regular inspection and cleaning of the oil circuit, ensuring correct connection of the oil pipe, and adjusting the pressure value to an appropriate range are the key to improving the continuity of the breaker.

Troubleshooting Reduced Continuity in Hydraulic Breakers

　　2. Reduced impact force of hydraulic breaker: details determine success or failure

　　The reduced impact force directly affects the crushing efficiency. Hydraulic breaker oil circuit leakage, insufficient control bolt stroke, oil circuit blockage and excessive oil temperature are all the culprits that lead to reduced impact force. To avoid this problem, it is recommended to regularly check the oil circuit sealing, ensure that the control bolt stroke is moderate, clean the oil circuit impurities in time, and keep the oil temperature within an appropriate range. These seemingly small details are actually related to the overall performance of the breaker.

　　3. Insufficient impact frequency of hydraulic breaker: system optimization is imperative

　　Insufficient impact frequency often means that there is a problem with the hydraulic system. Insufficient pressure or flow, loose drill rod, wear of hydraulic seals, contamination of hydraulic grease and failure of safety valves may all lead to a decrease in impact frequency. To address these problems, we need to conduct a comprehensive inspection and optimization of the hydraulic system to ensure sufficient pressure and flow, tighten the drill rod, replace worn seals, use clean hydraulic grease, and verify the sensitivity of the safety valve. Through these measures, the impact frequency of the breaker can be effectively improved to ensure construction efficiency.

　　In summary, troubleshooting and maintenance of hydraulic breaker are essential. Only by deeply understanding the root cause of the failure and taking targeted measures can we ensure that the breaker is always in the best working condition and provide solid protection for your construction project.
