Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] Such as Figure 1-2 As shown, a 600Mpa screw rod lifting type ultra-high pressure test device includes a column 1, a top cover transmission box 2, a lifting screw rod 3, a plunger type piston 4, a steel ball guide ring sleeve 5, and an ultra-high pressure cylinder 6. It is characterized in that : Also includes: high-pressure large piston 7, high-pressure cylinder 8, linear guide column guide rail 9, guide pressure head 10, combined skeleton self-sealing 11, base 12.
[0026] The top of the plunger piston 4 is movably connected with the screw lifter 3, and a linear guide rail 9 is provided on the outside, and a steel ball guide ring 5 is fitted on the cylinder mouth of the ultra-high pressure cylinder 6 to guide the ultra-high pressure plunger piston 3 Correct entry into the UHP cylinder without offset.
[0027] During the design, the ultra-high pressure cylind...

The invention relates to an ultrahigh-pressure biological test device with an elevation-type screw rod. A 600Mpa ultrahigh-pressure self-tightening sealing structure with double functions comprises a cylinder, a self-tightening pressing sleeve, a positioning combinational sealing ring, a self-tightening pressing head, a pre-sealing ring, a plunger and an expansion ring. The cylinder is internally provided with the self-tightening pressing sleeve contacted with the outer side at the front end of the self-tightening pressing head; the tail end of the self-tightening pressing sleeve is connected with the positioning combinational sealing ring; the pre-sealing ring is arranged on the outer side of the self-tightening pressing head; the plunger is arranged on the inner side of the cylinder; the plunger extends into a groove on the outer side of the self-tightening pressing head; and the front end of the plunger is provided with the expansion ring in matched contact with the self-tightening pressing head. The invention solves the problem that the sealing structure of the ultrahigh-pressure generating device in the prior art is poor in a sealing effect and can not meet the high-pressure requirement. The ultrahigh-pressure self-tightening sealing structure with double functions provided by the invention has a simple structure and a favorable sealing effect, and can meet the pressure requirement of 300-600Mpa.
Description
technical field [0001] The invention relates to a screw-rod lifting structure, in particular to an ultra-high-voltage test device for the cooperation of a linear guide post guide rail and a steel ball guide ring sleeve and the separate connection of an ultra-high pressure cylinder and a high-pressure large piston. [0002] Background technique [0003] At present, the domestically recognized imported ultra-high pressure test equipment is expensive, which is the bottleneck that suppresses the development of China's ultra-high pressure liquid technology application technology. In order to break the application bottleneck of expensive imports, the Ministry of Industry and Information Technology recently released the "Guidelines for the Development of Key Common Technologies in Industry (2011)". "Development Guide" industrial common technology is related to the general technology of industrial development, has the nature of quasi-public products, can be widely used in one or mo...
