1. Equipment parameters and configuration

Two. Main uses:

The WAW series microcomputer controlled electro hydraulic servo universal testing machine is mainly used for tensile test, compression and bending test of metallic materials. The concrete, brick, tile, rubber and their products can be tested after adding the corresponding accessories.

This machine is made up of a dual column, double screw cylinder, lower cylinder main engine and a piano type oil source control cabinet. The oil pump adopts the low noise and high performance gear pump imported from Italy Mazu. The drawing space is above the main engine, and the compression and bending test space is located between the main beam and the work table. The adjustment of the test space is realized through the movement of the middle beam, and the middle beam is lifted by chain drive.

This machine adopts computer automatic closed-loop control, sensor force measurement, computer screen real-time display, storage and printing function, and sample hydraulic automatic clamping. After the test, the maximum force, tensile strength, yield strength, modulus of elasticity, elongation after failure and shrinkage of the section were obtained automatically.

Three. Function and characteristics:

The special super thick pincer seat makes the jaw fully contained in the seat of the jaw when holding the sample with the jaw, so that the clamp is more reliable, and the possibility of the deformation and damage of the horn shape is eliminated, and the service life of the equipment is greatly improved.

The wear-resistant lining plate is added between the jaw seat and the clamp plate, and the phenomenon that the oxide skin falls into the scrap of the slant surface of the jaw seat is eliminated during the metal stretching process, making the clamping process more slippery and more firmly clamped.

The machine has stable balance, low noise, high efficiency and wide speed range.

Four. The introduction of software function

(I) the advantages of the system:

(2) the system is all digital design with high accuracy, stability and safety.

(3) the system adopts digital zero adjustment and parameter calibration.

(4) the system control parameters can be automatically calibrated without the occurrence of the phenomenon that the system can not be used after the technician has left.

(5) after the test, the system automatically analyzes the test data and curves, and can also be analyzed under manual intervention.

(6) special test reports can be customized according to customer requirements.

(7) system software integrates more than thirty national standards or test methods such as GB/T228-2002;

(8) the software is simple and easy to operate.

(9) the software can display the loading speed of the load;

(10) query, print and browse test data through the network.

(two) brief introduction of measurement and control acquisition card:

(1) the appearance of the measurement and control acquisition card

A brief introduction to the circuit of measurement and control acquisition card.

The AD800 full digital data acquisition card is a built-in microcomputer PCI test card based on PCI interface, which is in line with the PCI2.1 specification. The card can be inserted directly into any PCI inserting slot of the microcomputer. Through a simple connection, the card can be directly connected to the test machine, and the microcomputer automatic measurement and control can be realized, and the plug and play can be really done. The AD800 universal test card integrates programmable amplifier A/D conversion, digital I/O, counting and pulse occurrence (PWM), square wave occurrence (SWP) and other functions. Its system structure is reliable and simple, and has very good interchangeability.

(3) the technical performance of AD800 acquisition card:

The whole system adopts digital design, which is safe, stable, reliable and high precision.

There is no adjustable device in the whole system, digital zero adjustment and automatic calibration of measurement and control parameters.

The system integrates CPLD computing devices with high speed operation ability and real-time processing of digital signals.

This system adopts PCI2.1 bus standard, easy to expand, easy to upgrade and plug and play.

Automatically check zero.

Nine. Brief introduction of measurement and control software:

(1) introduction of MaxTest software:

Based on the WINDOWS operation platform, the software is simple and powerful, and has a human-machine conversation structure.

Four digit digital display test force value, accuracy for each gear range 20% starts to show the value of + 1%;

In four files, the digital display is deformed, and the accuracy is 20% for each gear range 20%.

At the same time, recording force time, deformation time, force deformation test curve, can switch observation at any time, random zoom down, horizontal or vertical movement, real-time high-speed sampling;

On the basis of automatic analysis, the results of elastic modulus, yield strength, tensile strength and so on are automatically calculated at the end of the test, and the accuracy of the analysis can be improved by manual analysis.

Test data is managed by standard database, and all test data and curves are automatically saved.

During test, the test curve is displayed in real time. After testing, the test data, curves and information of the test piece will be displayed in this operation window.

This set of control software has now integrated more than 100 national standards or test methods, so many national standards can meet the needs of customers' multifaceted test. The test report method can be customized and updated at any time according to the needs of the customer, which can bring great convenience to the customers.

The database can be Querying Historical test data, and only need to input certain conditions to find the test data immediately.

The force and deformation can be automatically calibrated. After we have completed the debugging, if the user is not allowed to feel the indication or the measurement parameters are changed, only click the automatic correction button, and the system parameters will be restored to the state of the debug.

Only use the mouse to operate on the two acquisition channels can be zero, the system is usually only once zero zero, in normal use, the system will automatically return to the real zero point;

A group of similar samples can be aggregated and analyzed, and the measured data can be compared and the average value can be calculated, so that the samples can be aggregated and printed in batches.

It provides a variety of report print formats, and users can edit reports of any format according to needs (batch processing, control programmer, MaxDoc report processor, MaxXls report processor, etc.).
