Exhalation valve housing strength testing machine function:
According to the function, it can be divided into digital display and microcomputer control. The digital display is controlled by a single-chip computer or a microcomputer, and the operation is simple and convenient; the microcomputer control is very powerful, the whole test process is controlled by a computer, and no multi-language printing can be realized without manual intervention.
1. Automatically clear: the computer receives the test start command, and the measurement system automatically clears it.
2. Automatic return: After the automatic identification test breaks, the movable beam automatically returns to the initial position at high-speed.
3, automatic save: test data, and experimental conditions automatically save the disk, to prevent data loss caused by sudden power failure forgotten to save the disk
4, the test process: the test process and measurement, display, analysis, etc. are completed by the microcomputer
5, display mode: data and curve dynamic display with the test process
6. Reproduction of results: The test results can be arbitrarily assessed, and the data curve can be reanalyzed.
7. Curve traversal: After the test is completed, the mouse can be used to find the point-by-point force value, and deformation data of the test curve, which is convenient and practical for obtaining test data of various materials.
8. Comparison of results: Multiple test characteristic curves can be superimposed, reproduced, enlarged, and presented with different colors for analysis and comparison;
9. Curve selection: You can select the stress strain, force time, intensity time and other curves to display and print according to your needs;
10. Batch test: After the test with the same parameters are set once, the test of a batch of samples can be completed in sequence;
11, test report: (according to customer needs)
Stretching: greater force, tensile strength, elongation at break, modulus of elasticity, etc.
Bending: greater force, bending strength, deflection, modulus of elasticity, etc.
Compression: large force, compression strength, yield strength, elastic modulus, etc., can also be programmed and printed according to the format required by the user;
12, limit protection: with program control, and mechanical two-level protection;
13. Overload protection: automatically stop when the load exceeds 10% of the rated value;
Emergency stop: There is an emergency stop switch for emergency shutdown of the whole machine power supply;
Automatic diagnosis: The system has automatic diagnosis function, and the measurement system and the drive system is over-pressed, over-current, over-temperature, etc., and the abnormal situation is immediately stopped;
14. Implement independent operation of the host and the microcomputer;
Exhalation valve housing strength testing machine performance characteristics:
1. Using AC servo motor and AC servo speed control system to control the test process, the control accuracy and quality are greatly improved, stable, low noise (substantially no noise at low speed) and the control speed range is greatly widened (0.05-300 mm/min). It is not only conducive to the low-speed test of conventional materials (metal, cement, concrete, etc.), but also to the high-speed test of non-metallic materials (rubbers, etc.), and can also be used to quickly adjust the test space during no-load, saving auxiliary test time. The test speed meets the requirements of the test speed of all conventional metals and non-metal materials in China.
2. The speed reduction mechanism consisting of synchronous toothed belt and precision ball screw pair “strong and strong” makes the structure more concise and bright, and the transmission efficiency is greatly improved. The height of the lower table of the main machine and the height of the main engine also decrease. The appearance is more coordinated.
3. It adopts the independent double space structure of stretching and compression, which is easy to operate and avoids the cumbersomeness of changing different test attachments when stretching and compressing bending in the same space.
4. Different specifications of sensors can be configured according to requirements, so that the test range is greatly widened to meet the measurement requirements of different test loads.
5. The main machine adopts a fully sprayed plastic shell, which is generous and beautiful.
6. Adopt advanced control technology, with three closed-loop control modes of stress, strain and displacement. The control loops can be automatically switched between each control loop, and the impact-free smooth transition can be realized when switching between modes. The test force, peak value and displacement can be displayed simultaneously. , speed, test status, test curve, etc.
7. It can control and maintain the rate of test force, deformation and displacement.
8. It can realize the fast/slow lifting adjustment of the beam when the sample is clamped, and the operation is flexible and free to switch.
9. It has the function of returning to the initial position after the test is finished, which is quick.
10. It has perfect limit protection function and function such as overload, over-current protection and automatic shutdown of test break which are reliable and safe.
11. Self-built powerful test database, test data can be saved, inquired and called at any time.
12. Provide a variety of report printing interface, users can edit the report in any format as needed, and print out;
13. The entire control system has high cost performance and high reliability.
14. According to national standards or user-supplied standards, the material is subjected to tensile test, and the test data are statistically processed and processed, and then the test curves, and test reports of various requirements are printed and printed, and load-time, load-displacement, displacement can be selected. — Time, deformation, time and other test curves display, amplify, compare, traverse functions and monitor the test process in real time. Smart and convenient.
15. Provided to the professional user “Standard Add Program Editor” software, users can flexibly add the required standards according to actual needs;
16. All Chinese Windows platform test software, with strong data and graphics processing capabilities, can instantly print out a complete test report and test curve, can reserve data interface, directly connect to the comprehensive information of the enterprise (laboratory) Manage the network. It can also be customized according to specific conditions of the user's local area network.
