The experimental process of the kinematic viscosity tester-Chemical Instrument Network

Kinematic viscosity testerDesign, manufacturing, and inspection complianceGB/T265,ISO3104,ASTM D445Waiting for standards; The instrument consists of three main components: a testing host, a vacuum servo box, and a cleaning servo box; The instrument adopts a hardware system consisting of an industrial control computer and a microcontroller. The microcontroller is used to achieve constant temperature control and viscosity testing, with high real-time performance, making the test results more accurate.

Kinematic viscosity testerThe experimental process:

1.Automatic sampling: There are one injection tray on each side, and users can place them on each tray1-12An oil sample, according to the input sample cup number, the instrument will automatically search for the sample;

2.Automatic sampling: The instrument will automatically lift the sample cup up to the suction nozzle of the viscosity tube, sample automatically through vacuum negative pressure, and stop automatically after reaching the upper limit of the detected bubble. Users can also set the delay time for sample suction;

3.Automatic constant temperature immersion: After the instrument aspirates the sample, the oil sample is kept in the viscosity tube and immersed in a constant temperature bath. The temperature of the constant temperature bath and the constant temperature immersion time of the sample are set by the user before the experiment;

4.Automatic viscosity testing: After the automatic immersion of the instrument is completed, it will automatically open to the atmosphere and start to fall freely for testing. The liquid level position will be automatically detected, and the dripping time will be automatically recorded. After completing * tests, the next test will be automatically carried out. The number of tests for each oil sample is set by the user themselves,2-4Next time. Automatically calculate the kinematic viscosity based on the number of tests and take the average value to obtain the result;

5.Automatic cleaning: After each oil sample test is completed, compressed air is automatically pressed into the cleaning agent for automatic cleaning. The cleaning time and frequency are also set by the user before the test, and the cleaning includes two channels of cleaningAAnd cleaningBUsually, a cleaning agent is used as standard, and users can set and use it for cleaning themselvesAOr cleaningBOr clean itACleaningBAll choose;

6.Automatic drying: After cleaning, the instrument will use compressed air to automatically dry, and the number and duration of drying will be set by the user.
