WAW-G series of computer controlled servo strand universal testing machine
Computer controlled servo universal testing machine (strand-specific) all-digital closed-loop control system, to achieve power, displacement, deformation of the three closed-loop control requirements can be any combination between control, smooth handoff. Beam using carbon steel, The high degree of chrome plated steel polished, beautiful, rust, good cut trough light bars, to achieve maximum space stretching 1100mm, 900 mm, 700 mm adjustment, more humane;. master cylinder using gap seals and Manchester seal structure, double-sealed, long-term work to ensure zero leakage; Lancaster closure using cylinder seals, cylinder pressure is adjustable; use the US company spoke World Civil load sensors, anti-pull test (pressure) ability, good linearity, stability precision testing machines to meet the 0.5 requirements; displacement sensor uses optical encoder withdrawable
The main function:
Suitable for strand tensile testing, tensile specimens of various metallic materials, compression, bending, shear and other tests, as well as special tests of some products.
1: double space structure, space between the upper and lower beams stretched, compressed space under tension and compression testing very easy to convert between the beam and the test station; upper and lower beams are made of steel castings, high strength, good security;.
2: Unique jaw and fixture design, to ensure that the effect of strand breakage
3: Large scale patented technology from the extensometer fully meet the requirements of the standard
4: oil source design with quiet, environmentally friendly, humane, unique pressure servo system, reduce energy consumption, reduce heat and protect the oil;
5: high-speed DSP platform, its high level of integration, strong control, data processing capabilities, high reliability, is the use of other processors can not match the test machine.
6: The neuron adaptive PID algorithm based all-digital, three closed-loop (force, deformation and displacement) control system, force, deformation and displacement of three closed-loop digital control, between the control loop can be switched automatically, and in all ways achieve a smooth transition without impact time switching.
7: 24Bit high-precision data acquisition systems, high-resolution, expandable to 8 AD acquisition.
8: USB1.1 communication, the communication speed of 12Mb / s, using full-speed mode, the bulk transfer mode.
9: System board 4-layer PCB unique wiring method jamming, anti-jamming capability.
10: In addition to the power supply interface, all other interfaces using a standard USB interface, plug and play interfaces such interface enables hot-swappable, plug and play functionality that is online software interface features can be set up so that each interface layout is neat. reasonable, plug convenient.
