Vibroseis is a set of hydraulic control,mechanical transmission,electronic control and gas control in one of the precision equipment,after long-term use and development,any component in the hydraulic system has its own unique functional problems,for maintenance technicians put forward higher requirements,that is,need to understand the characteristics of hydraulic components to understand the primary and secondary relationship of the system.In the field production can be more targeted to solve the problem.Based on the analysis of the wor-king principle of EV-56 vibroseis drive system and confluence technology system,this paper summarizes the fac-tors leading to the fault and puts forward a reasonable solution,and puts forward the importance of considering the whole solution to the hydraulic system fault.
