Pressuring oil pipe 8 and accumulator 9, and the pressure sensor 5 that is shown with numerical value；
3, nitrogen is injected into accumulator 9, until pressure sensor 5 shows that numerical stability in 130Bar or so, stops injection nitrogen
Gas；
If 4, hydraulic push rod 6 is during the motion, liquid medium sealing circle 7 or hydraulic oil seal circle 12 leak, then pressure
It shows that pressure can decreased significantly on sensor 5, that is, reaches hydraulic cylinder sealing real-time detection function.
