The purpose of this utility model is achieved in that
The accumulator of a kind of on-line monitoring piston displacement, it is made up of gas end end cap, cylinder body, piston, oil end end cap, transition valve block, displacement transducer, and described gas end end cap is fixed with cylinder body left end, and gas end end cap is provided with air valve joint；Described oil end end cap is fixed with cylinder body right-hand member.
Described piston is placed in cylinder interior, between gas end end cap and oil end end cap, is provided with through hole, through hole is fixed with magnet ring, a Y type rubber seal, an O RunddichtringO and the 2nd Y type rubber seal in the middle of piston；The sensor rod of institute's displacement sensors passes piston hole.
Described transition valve block is fixed on oil end end cap by screw, is sealed by the 2nd O RunddichtringO, and transition valve block is provided with displacement transducer installing port and accumulator charge and discharge hydraulic fluid port；Institute's displacement sensors is threaded connection and is fixed on transition valve block, is sealed by the 3rd O RunddichtringO.
Institute's displacement sensors is moved by the magnet ring on piston, and the change in displacement of piston is changed into the signal of telecommunication, and the signal of telecommunication is transferred to the devices such as external PLC, display screen by eight pin circular shield joints and carries out position display.
Described transition valve block length L1 and the oil long L2 of end end cap, displacement transducer detection initial length is 30mm, and accumulator of the present utility model initial detection length is (L1+L2-30) mm, is set to the leading zero's displacement of accumulator.
Compared with prior art, this utility model has the advantages that
The accumulator of a kind of on-line monitoring piston displacement of the present utility model, simple in construction, easy to operate, it is possible to implement on-line monitoring accumulator piston displacement, just can apply on the basis of not changing conventional piston accumulator structure, grasp accumulator duty constantly, guarantee whole system is properly functioning, owing to accumulator volume is little, and working stability, displacement monitoring is accurate, can meet on-the-spot various working condition requirement.
