The solutions to pressure relief for the large and small arms of small excavators mainly include the following aspects:
Analyze the operating environment and objects: First, you need to analyze the working environment and operating objects of the small excavator, including ambient temperature and workload. This helps determine whether the pressure relief problem is caused by excessive ambient temperature or excessive load.
Select the appropriate hydraulic oil: Select the appropriate hydraulic oil based on the analysis results of the working environment and objects. This ensures proper operation of the hydraulic system and avoids problems caused by mismatched oils. At the same time, the hydraulic oil should be replaced regularly and attention should be paid to purchasing genuine hydraulic oil to maintain the quality of the oil.
Maintain the filter element: Replace the filter element in the hydraulic system promptly to ensure the cleanliness of the hydraulic oil and prevent impurities from causing damage to the system. When replacing the filter element, you should choose products from regular brands and avoid using inferior filter elements.
Check the oil seal and safety valve: If the arm drops during operation, it may be because the boom oil seal is damaged or the oil return safety valve is faulty. In this case, the oil seal needs to be inspected and replaced, and the oil return safety valve needs to be overhauled. If the problem persists after replacing the oil seal, it is necessary to further check whether the pressure value of the pump valve group is normal.
Adjust Boom Pressure: When dealing with pressure relief issues, you can troubleshoot by adjusting boom pressure. Reduce the boom pressure and observe whether the boom falls quickly. If it falls quickly, it may be a problem with the oil seal or safety valve. Through step-by-step troubleshooting, the root cause of the problem can be found and corresponding solutions can be taken.
Preventive maintenance: In order to prevent the occurrence of pressure relief problems in the large and small arms of small excavators, preventive maintenance should be performed regularly. This includes checking the tightness of various components of the hydraulic system, checking the oil level and temperature, and regularly replacing filters and hydraulic oil. Through preventive maintenance, potential problems can be discovered and solved in time to ensure the normal operation of the excavator.
Train operators: The skill level of the operator is critical to the proper operation of the excavator. Operators should be trained and assessed regularly to improve their skill level and ability to respond to various excavator failures. Through training, operators can better use and maintain excavators and reduce the occurrence of failures.
Maintenance service support: If the small excavator has problems such as pressure relief in the large and small arms, you should contact professional maintenance service support in time. Professional maintenance personnel can quickly locate the problem based on the fault phenomenon and provide effective solutions. During the maintenance process, operators should actively cooperate with maintenance personnel and provide necessary assistance and information.
Records and statistics: Establishing an excavator operation record and fault statistics system will help analyze the use and maintenance of the excavator. Through recording and statistical data, potential problems can be discovered in time and corresponding measures can be taken to improve the reliability and service life of the excavator.
To sum up, solving the pressure relief problem of the small excavator's large and small arms requires starting from many aspects, including analyzing the operating environment and objects, selecting the appropriate hydraulic oil, maintaining the filter element, checking the oil seal and safety valve, adjusting the boom pressure, and carrying out prevention maintenance, training operators, seeking maintenance service support, records and statistics, etc. By comprehensively applying these methods, the pressure relief problem can be effectively solved and the excavator can be kept in good operating condition. At the same time, operators should have a high degree of safety awareness and responsibility, and strictly abide by operating procedures to ensure the safe use of excavators.
