CVA is a component of logging instrument,which needs to be filled with oil in vacuum condition.This paper studies that CVA vacuum filling device uses vacuum pump to vacuum vacuum barrel,and is equipped with magnetic stirrer to increase hydraulic oil flow,so as to ensure that CVA oil filling meets the maintenance requirements and the internal hydraulic oil is completely filled in vacuum state.Therefore,the logistics transportation time of oil filling commissioned by external suppliers is greatly shortened,and the work efficiency and work quality are improved.
