Automatic Quenching Oil Medium Cooling Performance Tester 　

Product model: JF0220Z

Product Introduction

This instrument is the first product in China that adopts computer automatic control, which replaces the previous paper recorder, which makes the operation easier and reduces the manual procedures of the operator, thus ensuring the accuracy of the results. The machine consists of a host computer, a computer-controlled automatic test system, a heating furnace, and a stirring system. The user only needs to put the sample into the test cup and press the "Start" button on the computer, and the instrument will automatically measure and save the results.

Over the years, the quenching medium testing method has changed from relatively backward to advanced from the magnetic method, the five-second method, the hot wire method to today's cooling curve method, and has gradually become scientific and reasonable during this evolution. The intervention of computer automatic test makes this technology more complete, thus realizing the desire of fast, accurate and reliable assessment.

Main Feature

1. The microcomputer temperature control system automatically detects the laboratory temperature, and automatically calculates the heating rate according to the working environment to ensure the accuracy of the temperature.

2. The shell of the instrument is made of cold-rolled steel plate, and the surface is treated by electrostatic spraying and high temperature baking, which is easy to clean and corrosion-resistant.

3. The high-temperature furnace adopts Swiss high-quality electric heating wire as the heating element, with uniform temperature and long service life.

4. The furnace adopts 8-hole circulating heating tank to avoid the disadvantage that the heating wire is easy to burn.

5. The furnace body is made of stainless steel.

6. The low-temperature furnace is formed by a mold, and the aluminum bath is conducted to prevent the sample from entering the heater and causing fire.

7. The furnace connection adopts standard slide rail, which is slidable and easy to maintain.

8. The inner hole of the furnace is equipped with an anti-signal interference slot to avoid electromagnetic interference during the test process, which will cause the data collected by the silver probe to be disordered.

9. Standard test probe test, in line with experimental standards.

10. The test probe is automatically released without manual intervention.

11. When the temperature of the furnace body reaches the set value, the microcomputer will prompt and test automatically.

12. Measurable medium: oil, water, quenching fluid, saline-alkali solution, steel rolling coolant, cutting fluid, etc.

13. Data acquisition adopts high-speed data acquisition card.

14. The instrument is equipped with an over-temperature alarm function.

15. The results are displayed in two ways: curve and data.

16. The parameters are modifiable.

17. The stirring rate can be adjusted according to different samples.

18. It can save 500 sets of result data.

19. Three groups of test curves can be compared at the same time.

20. You can query any temperature data and time data in the test.
