As a further aspect of the present invention: the guide sleeve A is connected with the high-pressure lens pad through a buckle.

As a further aspect of the present invention: install dust ring, PTFE + copper powder guide ring, phenolic aldehyde clamp cloth guide ring in proper order through the draw-in groove in the uide bushing A, install dust ring, phenolic aldehyde clamp cloth guide ring, ste seal, general stopper circle through the draw-in groove in the uide bushing B, ste seal, lip circle, copper sheathing are installed through the draw-in groove in the uide bushing C.

As a further aspect of the present invention: the cylinder barrel is connected with the cylinder tail in a welded mode, the cylinder tail is connected with the sensor cover through bolts, and the cylinder tail is connected with the displacement sensor through threads.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses an at the inside dust ring that increases of uide bushing, PTFE + copper powder guide ring, ste seals, general cock ring and phenolic aldehyde press from both sides cloth, simultaneously in order to increase sealed reliability, on the basis of ste seals, increase general cock ring together again, at last in order to guarantee the guidance quality of hydro-cylinder, 6 phenolic aldehyde press from both sides cloth guide ring and copper sheathing have been used, greatly increase the support intensity of piston rod, the rigidity of piston rod has been guaranteed, compare with conventional hydraulic cylinder, can seal outside oil, the reliability is high, compact structure.

2. Through increasing two oil pressure measuring points, can observe whether there is oil to reveal, can judge from this whether the sealing washer damages, discover hidden danger in advance, prevent to pollute hydraulic oil.

3. Because the sealing washer is arranged on the uide bushing hole, and a large amount moreover, only can be very long with a uide bushing, and the processing technology nature is not good, consequently chooses three-section uide bushing for use, through threaded connection together, has both guaranteed the processing technology nature, simple to operate moreover.
