Description
Technical field rock mechanics experiment technology and apparatus field
Background technology world today resources exploration is drive on boldly to earth energy and disaster, crustal stress on-the-spot test
The crustal stress level of as shown by data 3500～5000m depth can reach 95～135MPa, and the exploitation of this kind of resource need to adopt ultra-deep
Drilling well and geologic body fracturing reform must be carried out to reservoir, this is accomplished by laboratory simulation large scale (0.4 meter of ＞) cube
Drilling and fracturing process of the rock sample under Deep ground stress effect, in this case testing machine needs are in each acting surface
Upper output and the substantially suitable payload values of Deep ground stress level, if the stress on each acting surface reaches 100MPa be accomplished by
1600 tons of pressure is exported on each face, and current testing machine hydraulic cylinder cannot be exported this due to the restriction of Sealing Technology
The stress of level, this just directly results in oil cylinder piston and the load of equivalent stress level cannot be exported on respective action face, and this is
Individual technical barrier.
The content of the invention present invention provides one kind in rock mechanics experiment to large scale (0.4 meter of ＞) cube rock-like
The split multilayer linkage pressurizing cylinder of high stress level is exported on product loading end.It is characterized in that by the way of multilayer oil cylinder is connected
To realize supercharging, the big load of output is solved the problems, such as；The pressurizing piston of multilayer oil cylinder is with bolts, realizes multilayer oil cylinder
The flexible uniformity of piston；The cylinder body and piston of every layer of oil cylinder in multilayer oil cylinder can be processed individually, can reduce processing
Difficulty and ensure process precision；Split multilayer linkage pressurizing cylinder is assembled by monomer oil cylinder, and oil-feed and oil return are equal
Realized by the one-way cock on bottom cylinder body；The each layer oil cylinder in top is connected with bottom oil cylinder by upper and lower cavity path,
Realize fuel feeding and synchronism output load simultaneously.Split multilayer linkage pressurizing cylinder can export the load much larger than monomer oil cylinder
Value, is to lay the foundation in laboratory simulation deep layer crustal stress.
General principle and technology：Split multilayer linkage pressurizing cylinder is using the original interconnected between split multilayer oil cylinder
Reason, in the case where cylinder interior maximum oil pressure value size determines, by the monomer oil cylinder layering superposition on common meaning, by each layer
The pressurizing piston of oil cylinder realizes linkage by screw rod connection, and the more conventional monomer oil cylinder of lifting surface area of such multilayer piston increases
Greatly, piston lifting surface area increase can cause the increase of overall oil cylinder output pressure, so as to obtain higher output pressure, realize
The purpose of supercharging.
This split multilayer links pressurizing cylinder, by the unidirectional oil-out 2 of the unidirectional oil-in 1, process of process, bottom cylinder body 3,
Bottom piston 4, process upper and lower cavity path 5, backhaul upper and lower cavity path 6, middle level piston 7, the unidirectional oil-in of middle level cylinder body 8, backhaul
9th, on the unidirectional oil-out 10 of backhaul, upper strata cylinder body 11, Piston attachment bolts 12, upper strata piston 13, process on lower oil cavitie 14, backhaul
Lower oil cavitie 15 is constituted.Split multilayer links pressurizing cylinder due to being input into height in the process upper and lower cavity 14 in process output pressure simultaneously
Hydraulic fluid presses oil and acts on stratum piston 4, middle level piston 7 and upper strata piston 13, can be with so compared with conventional monomeric oil cylinder
Effectively increase piston compression area to improve oil cylinder output pressure.
