Blind hole, is provided with equipped displacement bar in blind hole, displacement bar is connected with the displacement transducer one being installed in cylinder seat left end.
Further, the fairlead being fixedly installed between cylinder body and piston rod, described fairlead and cylinder body are also included
The contact surface formed is provided with at least 1 guide ring, and the contact surface formed between described fairlead and piston rod at least sets
Put 3 O RunddichtringOs and at least 1 dust ring.
Further, described fairlead right part is provided with lip platform, and lip decometer hoop is on cylinder body right side, and passes through nut cap
Extruding is fixing.
Further, described piston rod left end and displacement bar contact position are additionally provided with displacement bar sealing ring.
Further, the load-carrying ring being welded on cylinder body outer circumference face is also included.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model is provided with a blind hole at the middle part of piston rod, has been equipped with displacement bar in blind hole, displacement bar with set
Put the displacement transducer one at cylinder seat left end to connect, by the displacement of displacement bar induction piston bar, and then by piston rod
Displacement signal is converted into the signal of telecommunication, and then realizes the control of piston rod both sides pressure reduction again by being arranged on the flow control valve of outside
System, it is achieved being accurately positioned of piston rod.
