9 → H of press pump → F → (8 inside commutation) → D → B.While rodless cavity B is pumped into hydraulic oil, the hydraulic oil in rod chamber A must
Must be discharged simultaneously, the hydraulic oil in rod chamber A is to return to fuel tank 10 by bidirectional hydraulic lock 7, hydraulicdirectional control valve 8) in, hydraulic oil
Path be A → C → E → G → fuel tank 10.Oil cylinder extending action terminates, and 8 spool of hydraulicdirectional control valve is back to interposition, keeps living
Stopper rod is stationary；
When the piston rod (needs) of mode transfer oil cylinder 5 retracts, 8 spool of hydraulicdirectional control valve commutation, system hydraulic pump 9 passes through liquid
Pressure reversal valve 8, bidirectional hydraulic lock 7 are pumped into hydraulic oil to rod chamber A, at this point, it is by fuel tank → liquid that rod chamber A, which is pumped into hydraulic oil,
9 → H of press pump → E → (8 inside commutation) → C → A.While rod chamber A is pumped into hydraulic oil, the hydraulic oil in rodless cavity B must
It must be discharged simultaneously, the hydraulic oil in rodless cavity B is returned in fuel tank 10 by bidirectional hydraulic lock 7, hydraulicdirectional control valve 8, hydraulic oil
Path be B → D → F → G → fuel tank 10.Oil cylinder retract action terminates, and 8 spool of hydraulicdirectional control valve is back to interposition, keeps living
Stopper rod is stationary.
