Background technique
At present, conventional piston accumulator in use can not realize the actual displacement of on-line monitoring piston, and then fully can not understand the working state of accumulator, is difficult to judge that whether accumulator is working properly.In accumulator Long-Time Service process, the reason such as to rub for a long time due to piston and cylinder body and use fluid stained causes piston seals fail, and piston position changes, and then accumulator cisco unity malfunction; In Practical Project uses, when needs detect piston displacement, because detection facility complex operations is loaded down with trivial details, inefficiency, can not meet field working conditions requirement, is difficult to realize on-line monitoring.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of accumulator of on-line monitoring piston displacement is provided, it is simple for structure, simple to operate, long service life, the basis substantially not changing conventional piston accumulator structure just can be applied, can be embodied in line monitoring piston displacement, grasp accumulator working state constantly, ensure that whole system is normally run, on-the-spot various working condition requirement can be met.
The object of the present invention is achieved like this:
An accumulator for 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 and cylinder body left end are fixed, and gas end end cap is provided with air valve joint; Described oil end end cap and cylinder body right-hand member are fixed.
Described piston is placed in cylinder interior, holds between end cap, be provided with through hole, through hole be fixed with magnet ring, a Y type rubber seal, an O RunddichtringO and the 2nd Y type rubber seal in the middle of piston at gas end end cap and oil; The sensor rod of institute's displacement sensors is through piston hole.
Described transition valve block is fixed on oil end end cap by screw, and by the 2nd O RunddichtringO sealing, transition valve block is provided with displacement transducer mount inlet and accumulator charge and discharge hydraulic fluid port; Institute's displacement sensors is threaded connection and is fixed on transition valve block, by the 3rd O RunddichtringO sealing.
Institute's displacement sensors is moved by the magnet ring on piston, changes the change in displacement of piston into electrical signal, and electrical signal 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 holds the long L2 of end cap with oil, and it is 30mm that displacement transducer detects initial length, and the initial detection length of accumulator of the present invention is (L1+L2-30) mm, is set to the leading zero's displacement of accumulator.
Compared with prior art, the present invention has following beneficial effect:
The accumulator of a kind of on-line monitoring piston displacement of the present invention, structure is simple, easy to operate, can be embodied in the displacement of line monitoring accumulator piston, the basis substantially not changing conventional piston accumulator structure just can be applied, grasp accumulator working state constantly, ensure that whole system is normally run, because accumulator volume is little, working stability, displacement monitoring is accurate, can meet on-the-spot various working condition requirement.
