Abstract
Hydraulic transmission system as an important part of modern industrial equipment, its stable and reliable operation is directly related to the efficiency and safety of the entire production line. However, because of the complexity of the hydraulic transmission system structure and the diversity of the working environment, its fault diagnosis and elimination has become a challenging task. In this paper, the method of fault diagnosis and elimination of hydraulic transmission system is deeply studied, aiming at providing a set of systematic and scientific diagnosis process and elimination strategy to guide the maintenance of hydraulic transmission system in actual production. In this paper, the working principle and structural characteristics of the hydraulic transmission system are summarized, and the basic knowledge of fault diagnosis and removal is defined. Then, the common fault types of hydraulic transmission system are analyzed in detail, including abnormal pressure, abnormal speed, abnormal action, etc., and the possible causes and effects of these faults are pointed out. On this basis, this paper puts forward a variety of fault diagnosis methods, including direct test, instrument test, element replacement and periodic test. Each method has its unique advantages and application scenarios, and maintenance personnel can flexibly choose according to the actual situation. In the aspect of troubleshooting, this paper emphasizes the importance of accurately judging the cause of the fault, and gives the detailed troubleshooting steps. First of all, the possible cause of the failure is determined by the site investigation and data analysis. Secondly, proper diagnostic tools and methods are used for verification to ensure the accuracy of fault location. Finally, according to the cause of the failure, take the corresponding repair measures, such as replacing the damaged components, adjusting the system parameters, etc., in order to restore the normal operation of the hydraulic transmission system. This paper also discusses the measures to prevent the failure of the hydraulic transmission system, including keeping the hydraulic oil clean, preventing air from mixing, controlling the oil temperature, etc., in order to extend the service life of the system and reduce the failure rate. At the same time, this paper also emphasizes the importance of regular maintenance and maintenance, through regular inspection and replacement of wearing parts, you can find and deal with potential problems in time to prevent the expansion of faults. The fault diagnosis and removal of hydraulic transmission system is a complicated and important work. The methods of diagnosis and elimination, preventive measures and maintenance suggestions proposed in this paper provide a strong guarantee for the stable operation of the hydraulic transmission system. In the future, with the continuous progress of technology and the continuous expansion of application fields, the fault diagnosis and elimination methods of hydraulic transmission systems will continue to improve and develop.
