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 discloses a lead screw lifting ultrahigh pressure biological testing device and belongs to the technical field of hydraulic device science. The lead screw lifting ultrahigh pressure biological testing device comprises a high-precision linear guide post, a high-precision linear guide rail, a high-precision steel ball guide sleeve, a high-precision guide ring, a high-pressure / ultrahigh-pressure lower cylinder, an upper piston plunger pressing head, a self-tightening W-shaped seal; and the lead screw lifting ultrahigh pressure biological testing device is characterized by also comprising a lead screw lifting form, a plunger type piston, a self-tightening guide pressing head tensioning ring, a pre-sealing ring, a piston type seal head and a lifting lead screw, which are connected to form a whole body, and the high-precision steel ball guide sleeve and the high-precision guide ring are matched. The problems that the device is heavy in structure and poor in pressure-stabilizing effect, the multi-condition multi-pressure test range is limited and the operation is troublesome in the conventional ultrahigh pressure technology are solved, the application requirements of high pressure are met, the requirements of the 300-600Mpa pressure test can be met, and the media includes water and oil.
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...
