Fault Diagnosis and Maintenance Techniques for Hydraulic System of Common Construction Machinery

The application of construction machinery is an important technical condition to ensure the development of industrialization. The stability of its equipment operation is a necessary condition to maintain industrial production efficiency. In the application of construction machinery, the use of hydraulic system is more frequent, because the hydraulic system in the long-term use often appear various problems, which needs to strengthen the fault diagnosis and maintenance technology of the hydraulic system of construction machinery, in order to make it in a good working state. This paper introduces the working characteristics and fault types of hydraulic system of construction machinery, lists the diagnosis methods of hydraulic system fault, and puts forward the specific application of hydraulic system fault maintenance technology.
