Research on Fault Diagnosis Technology of Hydraulic System of Construction Machinery
The hydraulic system of construction machinery often has various faults in the actual operation.Rapid diagnosis plays a vital role in maintaining the normal operation of the system.Based on this,by introducing the basic principle and structure of the hydraulic system of construction machinery,the common fault types of hydraulic system are classified,including hydraulic pump oil leakage,valve stuck,etc.,and the application of different fault diagnosis techniques in the hydraulic system of construction machinery is analyzed.Practice has proved that by understanding the structure and fault type of hydraulic system,selecting the appropriate diagnostic method for fault diagnosis,and constantly exploring new diagnostic technology,the accuracy of fault diagnosis can be effectively improved,and the maintenance of construction machinery hydraulic system can provide good support.
