The present invention has the following advantages that compared with prior art:
1st, simple structure, good reliability is easy to operate, can detect the dynamic and static sealing of seal assembly Performance.If fluid is leaked from seal assembly, oil pressure meter reading can change, so that very easily Know testing result.
2nd, three sections of compound rods use three-section split structure, are easy to assembling.
Below in conjunction with figure, the invention will be further described with embodiment.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Embodiment 1:
The dynamic sealing performance detection means of three-stage seal assembly, including cylinder 1, support frame 2, left end Lid 3, right end cap 4, active guide rod 5, driven guide rod 6, three sections of compound rods 7, oil pressure gauge 8 and oil-feeds Pipe 10.
Left end cap 3 and right end cap 4 are separately mounted to the two ends of cylinder 1 and are connected with support frame 2.
It is communicated with the outer wall of cylinder 1 to the oil pressure gauge interface 11 and oil-feed interface 12 of the inner chamber of cylinder 1. Oil pressure gauge 8 is connected on oil pressure gauge interface 11.
Three sections of compound rods 7 are arranged in the endoporus of cylinder 1 by the annular boss 71 in its two ends outer rim, ring Sealed by seal assembly to be detected between shape boss 71 and the inwall of cylinder 1.Two annular boss 71 it Between form Ring-cylindrical oil pocket 9.And the oil pressure gauge interface 11 on cylinder 1 is communicated to oil-feed interface 12 Ring-cylindrical oil pocket 9.Three sections of compound rods 7 include intermediate bar 72 and are threaded in 72 liang of intermediate bar respectively Left bar 73 and right bar 74 in the screw of end;Two annular boss 71 on three sections of compound rods 7 are respectively provided at On left bar 73 and right bar 74.
The right-hand member of active guide rod 5 is supported by guide pin bushing A20 and is arranged on right end cap 4, right-hand member termination and power Associated therewith, actuating unit drives active guide rod 5 to move back and forth, and left end is threaded in three sections of compound rods In the screw of 7 right-hand members.
The right-hand member of driven guide rod 6 is connected in three sections of screws of the left end of compound rod 7, and left end passes through guide pin bushing B30 Supporting is arranged on left end cap 3.
