The probe is a sensitive component for testing. The instrument is equipped with a Φ10×40mm silver probe and a nickel-chromium-nickel silicon thermocouple. Other sizes of probes are also available.
4. Lifting mechanism:
The lifting mechanism can make the test convenient and ensure the stability of each action.
Third, the software system
The software system of the instrument adopts the module structure, the user interface is the menu dialogue mode, and the screen is displayed as Chinese characters, which is convenient for user operation and query management.
The software block diagram is shown in Figure 2. The software can realize data acquisition, analysis and display of sampling results, drawing test result curves, and managing data file libraries for the quenching process.
1. Data acquisition module:
This module is the core of the software and includes the following sections.
(1) Parameter setting: Save the last sampled parameter every time. When setting, read the original data first, and enter the new value when changing.
(2) Temperature rise monitoring: After the parameter setting is approved, the temperature rise monitoring is entered. The temperature rise curve and the temperature rise temperature on the screen indicate that the computer enters the constant temperature stage when it rises to a temperature close to 810 °C.
(3) Quenching data collection: After 2 minutes of constant temperature, the probe will automatically drop and enter the medium (you can also press “Next†without using the constant temperature). At the same time, the computer collects the data of the probe thermocouple at the selected rate.
(4) Data processing: After data acquisition, use the mouse to click the “Next†button, the computer will process the data, and then display the sampling curve, temperature change rate curve, special temperature seconds, maximum rate, drop to 500 ° C, 400 ° C Or a time of 300 ° C, etc.
2. Drawing module:
The sampled processed curve is plotted on the coordinate graph.
3. File Management and Printing Module:
The module quickly completes the display of the data file directory, and can search by date, sample delivery unit, media name, selectively delete data files, and print saved data parameters.
Fourth, software operation
This software must be operated on a USB flash drive. The files in the USB flash drive do not need to be installed on the computer. After the computer is turned on, enter WindowsXP, insert the USB flash drive into the computer, and click the test system icon in the USB flash drive to enter the system of the cooling medium cooling performance tester.
The left part of the system has a data acquisition drawing area, and the right side of the experimental information, experimental process, experimental report, parameter adjustment four windows. The mouse clicks on the experiment and the green light is displayed in the lower right corner. Then click the "Next" button. Follow the instructions on the right.
Data collection
(1) Click "Experiment Information" to set.
(2) Click “Experimental Processâ€, and you can see the change of the temperature curve. When the temperature rises to near the set temperature.
(3) At this time, pay attention to the temperature rise change. When the temperature rises above 809 °C and reaches 809-810 °C, immediately press “Next†to enter the test cooling sampling.
2. Report generation
(1) Click the “Next†button with the mouse and give a test report after one calculation by the computer.
(2) In the lower part of the report is the test curve and the upper part is a table. The lower part of the form is the test data, the upper part is the test date, the test unit, the sample delivery unit, etc.; the test unit and date are not rewriteable, and other blocks can be filled in by the tester.
3. Query report
(1) After the mouse clicks the report button, it enters the query window of the test data that has been saved in the past.
(2) In the query window, you can query by date, sample unit, and media name.
Fifth, the experimental steps
Refer to the petrochemical department SH/T 0220-92 for details on the cooling performance of the heat treatment oil. This procedure mainly introduces the operation of the instrument and the operation of measuring other cooling media.
1. Connect the computer to the host computer with a cable, turn on the main power of the main unit, turn on the power of the computer, and start the computer to enter the test system.
2. Hang the probe on the small hook on the wire rope, then put it on the pulley and insert the probe into the furnace. Then place the probe in the middle of the furnace (because the temperature outside the furnace is high during operation, wear thick gloves to prevent hot hands).
3. There is a limit ring on the upper part of the probe. When the position of the ring is adjusted so that the probe is lowered to the position of the limit ring so that the probe cannot continue to descend, the lower end of the probe is just 10 mm on the bottom of the media container.
4. After the above operation is completed, the computer can set the sampling rate and enter the temperature rising acquisition phase. When the temperature rises to near the set temperature, place the prepared oil cup in the middle to prepare for testing. When the temperature rises to close to the set temperature of 810 °C, pay attention to the rising temperature. When the temperature rises to 810 °C, you can also press the “press next step†probe to automatically drop into the medium cup without entering the temperature, and enter the cooling collection stage.
5. The computer automatically performs data processing immediately and displays the acquired curve.
6. After the test is completed, raise the probe up a bit to make the media cup can be removed, then lower the probe with a soft cloth to wipe off the oil on the probe, then manually press the up button to raise the probe, and let the probe enter the furnace for the next test. Otherwise, the probe will enter the furnace with oil and will catch fire and produce black smoke. In order to test more accurately, the probe should be ground if necessary, and the probe should be removed when grinding. See the SH/T0220 standard for grinding methods and requirements.
7. The oil of the oil cup is required to be warmed according to the test requirements. The equipment for heating is a heating electric furnace, usually heated to 80 °C.
8. After the acquired curve is displayed, the computer calculates its differential curve and calculates various parameters required. The generated report can be saved or printed.
