WEW computer reveals the basic structure and main function of the omnipotent testing machine
1,Host computer: Dispose the putting host computer framework under the cylinder, this structure has reduced the host computer height greatly, it is convenient to transport, install, performance is steady, reliable, try the platform and go up and down and adopt electrical machinery, roller chain, guide screw transmission, realize and draw the adjustment in the space, it is easy to operate to test;
2,Observe and control the system: By the electric liquid servo oil source, digital PC servo controller, electric liquid servo valve, pressure sensor, measure and try a piece of guiding and is stretched and is counted out of shape, photoelectric encoder, testing machine specialized PC which measure displacement observe and control card, printer, multi-functional experimental software package, electricity control unit etc. to make up partly;
3,Standard electric liquid servo oil source:
1)Enter oil, reduce expenditure, transfer speed to be systematic for the intersection of load and person who adapt to, adopt ripe technology according to standard module Entrance design manufacturing, specially form a complete set and use for the servo omnipotent testing machine of the electric liquid;
2) Select the oil pump with ripe technology – electrical machinery for use, quality is reliable, performance is steady;
3) Adopting has load adapting to type that technology develops production by oneself that reduce expenditure and adjust the speed valve, systematic pressure steady regulating, there is no energy consumption of overflow by adaptive the intersection of constant pressure and the intersection of difference and flow, it is apt to carry on PID to close the ring to control;
4) Pipeline system: The pipeline, piecing and seal select a set of piece in groups with steady performance for use, guarantee the hydraulic system seals reliably, there is no seepage oil trouble to take place;
4,WEW computer reveals that tests the angry switch board of electromechanics universally:
All strong electric parts of a, system concentrate on the strong electric switch board, realize the strong electric unit and observe and control the effective separation of the weak electric unit, guarantee to observe and control the system without interruption, the work steady in a long-term;
B, set up manual operation according to sprain at the automatically controlled cupboard, switch, anxious to park, and the oil source oil pump is turned on and parked etc.;
5,Digital PC servo control system:
WEW-1000B computer reveals the universal testing machine producer
a) The system relies mainly on PC computer, digital PID regulates, adds the panel servo amplifier of PC card, observes and controls software and data to gather and deal with the software, can realize that closing the ring and controlling and controlling the smooth switch of the mode of strength, sample piston displacement out of shape is tested;
b) The system is looked after the unit by the signals of No. three ‘ A strength unit, cylinder piston displacement unit that experimental, try a unit out of shape) , the unit of controlling the signal generator, servo valve drive unit, servo oil source control unit, essential I/O interface, software system etc. to make up;
c) The systematic one closes the ring and controls the return circuit: Measure the sensor ‘ The intersection of pressure and sensor, the intersection of displacement and sensor, out of shape to guide and stretch counting) With servo valves, controllers ‘ Every signal recuperates the unit) , the servo amplifier makes up a plurality of and closes the ring and controls the return circuit together, realize experimental strength, cylinder piston displacement, sample closing the ring and controlling the function out of shape of the testing machine; It have,etc. speed experimental for strength,etc. speed cylinder displacement,etc. speed meeting an emergency control modes many kinds of, and can realize the smooth switch of the control mode and make the system have greater flexibility;
6,The panel servo amplifier of specialized PC card of the testing machine:
A, in order to insert and pull out the formula PC card board, employs the advanced computer bus control technology to be designed for the testing machine specially, there are programme-controlled simulation amplifiers, A/D changes, gathers the passway in digital quantity, digital quantity I/O,etc.;
B, should observe and control card while being specialized, and PC make up single Carlos observe and control the system, can link with sensor directly, observe and control and gather with the data, make the complicated one observe and control and what the data collecting system changes is succinct and reliable;
C, adopting the computer bus technology, inserts the computer to expand in the trough directly, digital circuit, return to zero, gain and adjust etc. realizing through the software, it is the testing machine that observes and controls the latest products unit of the technical development;
D, gaining and can be programmed one bunch of amplifiers, can be different enlarged multiples that gain;
E, sensor are for the basis voltage of bridge power and A/D chip to share the same voltage, the whole measuring system decays compared with the same period of last year, has realized that is for the hardware of the power of bridge to compensate technology;
F, changing sensitivity and resolution ratio requirement of meeting the system through many location A/D, have avoided the software time frequently the method reduces the characteristic of the systemmed;
7,Multi-functional experimental software package:
Operate interfaces in a, the whole Chinese? ?
B, computer display experimental strength, cylinder displacement, loading the speed, test data out of shape, draw time – experimental strength / many kinds of experimental curves such as the strength out of shape, out of shape – experimental; Carry on data processing automatically, the data processing method meets GB228-2002 standard requirement, not from head to foot surrender by some, most in a more cost-effective manner a bit, all kinds of regulations of proportions non- stress order, last stress to order,etc. all kinds of regulations all; Meet the experimental requirement of the testing machine pressure at the same time;
C, software offer the data analysis function at the same time, satisfies and tests personnel to carry on the test and analyze and carry on the data processing of special test.
D, possessing the stronger figure to operate the function, for instance, the experimental curve summation of the trends shows the function, the figure enlarges, intercepts the function, the cursor follows and reveals function,etc.;
E, adopting VXDs high-speed data to gather technology, realizes many passways (No. 16 at most) High-speed data gather;
F, system have storage that intact file operation functions are used for testing the curve, test data; Meanwhile, one yard of forms of test data all right ASCII is stored, so that users carry on data processing two times;
G, having single one to test the report form to output and test the report form and output and print the function in batches;
8,The control system have year, exceeds presuming, cutting out, piston and reaches terminal position,etc. and protects the function;
9,Hydraulic pressure clamps the oil source: The independent hydraulic pressure with low noise clamps the oil source, control the clamping of the chuck and unclamp.
