A kind of principle of work of plastic inspection well compbined test pick-up unit is: when axial load performance test detects, plastic inspection well 22 is vertically positioned on worktable I 2, Axial and radial loading hydraulic cylinder 3 action, band dynamic pressure plate 4 moves down, and applies the load pressure of regulation to plastic inspection well 22, and continues in required time to load, afterwards, cancel imposed load, observe the situations such as the breaking of plastic inspection well 22, crack, distortion, evaluate its axial load detection perform by regulation; When radial load performance test detects, plastic inspection well 22 traverse is placed on worktable I 2, Axial and radial loading hydraulic cylinder 3 action, band dynamic pressure plate 4 moves down, and applies the load of regulation to plastic inspection well 22, and continues in required time to load, afterwards, cancel imposed load, observe the situations such as the breaking of plastic inspection well 22, crack, distortion, evaluate its radial load detection perform by regulation.
When bellmouth shear-type load performance test detects, plastic inspection well 22 is placed on worktable I 2, Axial and radial loading hydraulic cylinder 3 action, band dynamic pressure plate 4 moves down compression plastic inspection well, topple in case shear when loading, move horizontally oil cylinder 10 action, band movable slider 6 moves to plastic inspection well 22 bellmouth position, shear loading hydraulic cylinder 7 action, saddle type pressure head 9 is driven to move down, the load of regulation is applied to plastic inspection well 22 bellmouth, and continue in required time to load, afterwards, cancel imposed load, observe breaking of plastic inspection well 22 bellmouth connection, crack, the situations such as distortion, and by its anti-shear performance of regulation evaluation.
When impermeability test detects, first plastic inspection well 22 well head made is placed on worktable II 20 down, be locked on worktable II 20 with locking anchor ear 23, do not come off during to ensure well head positiver sealing and to pressurize, starter motor 30, two-position three way magnetic valve reversal valve 31 is energized, in plastic inspection well 22, press water is filled by water hole 25, set the working pressure of pressure-regulating and pressuring-limiting valve 32 on request, pressure is to setting, pressurize certain hour, whether observe plastic inspection well cylindrical shell, connection, welded seam place etc. has infiltration, drainage, when welded seam strength test detects, first plastic inspection well 22 well head made is placed on worktable II 20 down, be locked on worktable II 20 with locking anchor ear 23, do not come off during to ensure well head positiver sealing and to pressurize, starter motor 30, two-position three way magnetic valve reversal valve 31 is energized, in plastic inspection well 22, press water is filled by water hole 25, set the working pressure of pressure-regulating and pressuring-limiting valve 32 on request, pressure is to setting, pressurize certain hour, observe plastic inspection well cylindrical shell attachment weld 24 place and whether occur crackle, fracture, damage, distortion, thus the testing inspection object reached plastic inspection well weld strength, the hydraulic pressure principle that welded seam strength test detects is: after filling water under high pressure in plastic inspection well 22, water under high pressure acts on plastic inspection well 22 barrel surrounding, act on the mutual counteract of hydraulic pressure acting force of well bore wall radial direction, but a tympanites can be made.Act on the hydraulic pressure acting force at well bore wall top, direction vertically upward, pit shaft is made to have the trend axially upwards stretched, and pit shaft body bottom is by locking anchor ear 23 and worktable II 20 consolidation, act on the hydraulic pressure acting force on well bore wall bottom worktable II 20, direction vertically downward, pit shaft is made to have the trend axially stretched downwards, thus make plastic inspection well 22 cylindrical shell receive axial acting force up and down, this makes plastic inspection well 22 produce axial tension to power, commissure is the weakness of axial tension power, what be first damaged should be plastic inspection well commissure.Therefore, high pressure water injection pressurization reaches the object of weld strength testing inspection.
When ring compliance teat detects, plastic inspection well level is placed on worktable I 2, Axial and radial loading hydraulic cylinder 3 action, band dynamic pressure plate 4 moves down to the radial imposed load of plastic inspection well 22, institute's imposed load is recorded after reaching regulation deformation values, Axial and radial loading hydraulic cylinder 3 is return, namely imposed load is cancelled, the force value completing any is measured, once rotate 120 ° afterwards and measure other 2 load values reached when regulation is out of shape, go out the ring flexibility of plastic inspection well 22 according to formulae discovery, get its mean value, evaluate its detection perform with this; During ring stiffness testing inspection, plastic inspection well level is placed on worktable I 2, Axial and radial loading hydraulic cylinder 3 action, band dynamic pressure plate 4 moves down to the radial imposed load of plastic inspection well 22, institute's imposed load is recorded after reaching regulation deformation values, Axial and radial loading hydraulic cylinder 3 is return, namely imposed load is cancelled, the force value completing any is measured, once rotate 120 ° afterwards and measure other 2 load values reached when regulation is out of shape, go out the ring stiffness of plastic inspection well 22 according to formulae discovery, get its mean value, evaluate its detection perform with this.
During impact property testing inspection, workpiece 26 level is placed on worktable I 2, according to the diameter of workpiece 26, regulates the height of limited block 12, and fixing, then require to regulate weight 13 height according to tension weight churning.Lifting hydraulic cylinder 18 action declines, band motor magnet 17 moves down, when contact beams 16, electromagnet 17 is energized, with beam 16 adhesive, lifting hydraulic cylinder 18 vertical motion, drive beam 16, weight 13 is promoted to regulation and requires height, electromagnet 17 power-off, electromagnetic attraction disappears, weight 13 falls with proximate freedom falling together with beam 16, weight 13 impinges upon on workpiece 26, the whereabouts that beam 16 is subject to limited block 12 is spacing, when after the impulse test completing a bit, workpiece once rotates 120 ° and measures other impact property of 2, observe the crackle of workpiece, the situation such as crack or breakage, by the side direction shock resistance of regulation evaluation workpiece, when bearing test of marking time detects, workpiece 26 is vertically placed on worktable I 2, Axial and radial loading hydraulic cylinder 3 action, band dynamic pressure plate 4 moves down workpiece pressing 26, move horizontally oil cylinder 10 action, move to marking time of workpiece 26 with movable slider 6 and detect position, shear loading hydraulic cylinder 7 action, briquetting 28 is driven to move down, specified load pressure is applied to marking time of workpiece 26, and continue in required time to load, afterwards, shear loading hydraulic cylinder 7 to return, namely imposed load is cancelled, observe 27 break of marking time of workpiece 26, crack, the situations such as distortion, its load-carrying properties of marking time are evaluated by regulation.
The present invention has following beneficial effect:
1, this testing machine load-carrying properties that can test the axial load of plastic inspection well, radial load, bellmouth shear-type load, sealing and welded seam intensity, lateral rings flexibility, ring stiffness, shock resistance and mark time, usable range is wide;
2, this testing machine can realize automatic control, automatically testing inspection, automatically record and data storage, and reliable operation, testing efficiency are high;
3, this testing machine can realize static load test detection, and also can realize dynamic loading experiment and detect, structure is simple, function is many, is easy to promote.
