Abstract

The invention discloses a fatigue test device for a flexible reaction capsule. The fatigue test device comprises an electric push rod, an electric push rod controller, a first access switch, a second access switch, a limiting metal block, a piston, a piston cylinder, a three-way valve, the flexible reaction capsule, a pressure sensor and a pressure collection circuit, wherein the first access switch and the second access switch are used for controlling reciprocating strokes of the electric push rod. According to the fatigue test device, the electric push rod controller controls the electric push rod to do a reciprocating motion, a reciprocating motion stroke of the electric push rod is adjusted by adjusting the positions of the access switches, the electric push rod drives the piston by the piston rod to do the reciprocating motion so as to change the volume of water in the flexible reaction capsule, the flexible reaction capsule deforms under the action of the atmospheric pressure, and a pressure value measured by the pressure sensor in a test process is collected and stored by the pressure collection circuit and is analyzed so as to judge whether fatigue rupture occurs to the flexible reaction capsule. The fatigue test device is simple in structure, is convenient to use and can realize the fatigue test to the flexible reaction capsule.

Description

The fatigue experimental device of flexible reaction capsule
Technical field
The present invention relates to a kind of fatigue experimental device, the device that particularly can react capsule and carry out torture test flexibility.
Background technology
Flexible reaction capsule is built in the reactor of water rock reaction under simulation high temperature and high pressure environment, and the reaction of water rock is carried out in flexibility reaction capsule.Flexible reaction capsule forms by having flexible titanium foil welding, has both utilized the corrosion-and high-temp-resistant performance of titanium foil material, has guaranteed again the flexibility of deformable compression, can realize real time sample.But yet there are no at home the equipment of flexible reaction capsule torture test at present.
Summary of the invention
The object of this invention is to provide a kind of fatigue experimental device of flexible reaction capsule.
Technical solution of the present invention is: flexible reaction capsule fatigue experimental device comprises the electric pushrod with limited block, electric pushrod controller, control the first approach switch of electric pushrod to-and-fro movement stroke, the second approach switch, piston, piston cylinder, T-valve, pressure transducer and pressure acquisition circuit, electric pushrod and the first approach switch are all connected with automatically controlled push rod controller with the second approach switch, piston is arranged in piston cylinder, electric pushrod is connected with the piston rod of piston, piston cylinder bottom is porose to be communicated with one end sealing of T-valve, the another two ends of T-valve are connected with one end and the flexible reaction capsule of pressure transducer respectively, the other end of pressure transducer is connected with pressure acquisition circuit.
Above-mentioned flexibility reaction capsule is to be welded by flexible titanium foil, is deformable.Pressure acquisition circuit can be single-chip microcomputer MSP430.The first described approach switch and the second approach switch can be used NPN open type approach switch.
The first described approach switch and the position of the second approach switch can be according to the reciprocating stroke adjustment of electric pushrod.
When flexible reaction capsule carries out torture test, flexibility is reacted in capsule and piston cylinder and is full of water, set the position of the first approach switch and the second approach switch according to testing requirements, so that the stroke that electric pushrod controller control electric pushrod moves back and forth, electric pushrod drives piston to move reciprocatingly by piston rod, the to-and-fro movement of piston changes the water volume of flexible reaction capsule inside, under the effect of atmospheric pressure, flexible reaction capsule can produce deformation, the collection of pressure acquisition circuit is also recorded the force value that in process of the test, pressure transducer is measured and stores, by the analysis of the force value collecting being judged to whether flexible reaction capsule fatigure failure occurs.
The present invention is simple in structure, easy to use, can realize the torture test to flexibility reaction capsule.
Accompanying drawing explanation
Fig. 1 is the structural representation of flexible reaction capsule fatigue experimental device.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, flexible reaction capsule fatigue experimental device of the present invention comprises electric pushrod 1, electric pushrod controller 11, control the first approach switch 9 of electric pushrod 1 to-and-fro movement stroke, the second approach switch 10, piston 3, piston cylinder 4, T-valve 8, pressure transducer 6 and pressure acquisition circuit 5, on electric pushrod 1, be fixed with spacing derby 12, electric pushrod 1 is all connected with automatically controlled push rod controller 11 with the first approach switch 9 and the second approach switch 10, piston 3 is arranged in piston cylinder 4, electric pushrod 1 is connected with the piston rod 2 of piston 3, piston cylinder 4 bottoms are porose to be communicated with one end of T-valve 8, the another two ends of T-valve 8 are connected with one end and the flexible reaction capsule 7 of pressure transducer 6 respectively, the other end of pressure transducer 6 is connected with pressure acquisition circuit 5.Before experiment starts, flexibility is reacted in capsule and piston and is full of water, the spacing derby on electric pushrod 1 is alignd with the first approach switch, adjust the position of the second approach switch according to testing requirements.After being ready to, give electric pushrod controller and pressure acquisition circuit supply, electric pushrod controller control electric pushrod is to left movement, in the time that spacing derby moves to the second approach switch position, the second approach switch is to electric pushrod controller transmitted signal, electric pushrod stop motion, and after certain interval of time, electric pushrod moves right, when the first approach switch detects spacing derby, electric pushrod stop motion, after certain interval of time, electric pushrod, to left movement, back and forth moves back and forth.
Above-described embodiment is that one of the present invention is enumerated, and those skilled in the art can, according to different designing requirements and design parameter not departing from various improvement and the replacing carried out in situation of the present invention, fall into protection scope of the present invention equally.
