Flash point is an indicator of the evaporability of oil products.
The lighter the fraction, the more evaporative it is, and the lower its flash point.
On the contrary, the heavier the oil fraction, the less evaporative, and the higher the flash point.
At the same time, flash point is an indicator of the ignition risk of petroleum products.
[No. 46 steam turbine oil ignition point] the ignition point is about 240℃;
Spontaneous ignition point 300 ~ 350℃;
The flash point is 180 ~ 200℃.
[Turbine oil] also known as turbine oil, usually including steam turbine oil, gas turbine oil, hydraulic turbine oil and antioxidant turbine oil, etc., is mainly used for the lubrication of turbine oil and sliding bearings, reduction gear, governor and hydraulic control system of the linkage unit.
The main functions of turbine oil are lubrication, cooling and speed regulation.
At present our country L - the TSA turbine oil product standards for GB11120-89, the standard will be turbine oil in 40 ℃ the kinematic viscosity values are divided into 32, 46, 68, 100, four grades (grades), viscosity and classy article, nonconforming product grade a and three quality grades, including classy article to the international advanced level, one for the international average SH106B automatic opening flash point tester, is according to the law of the People's Republic of China standard GB/T 3536 "petroleum products determination of flash point and burning point method (Cleveland KaiKouBei method)" the requirements stipulated in the design and manufacture.
Instrument according to the standard method of heating, automatic rise and fall, automatic ventilation, automatic ignition, automatic display, automatic locking flash point value, automatic printing results.
After the test can be automatically cooled, to achieve the full automation of the work process.
It has the advantages of accurate measurement, good repeatability, stable performance and simple operation.
Widely used in electric power, petroleum, chemical, commodity inspection, scientific research and other departments.
In line with ISO - 2719,GB3536 standards.
Instruments for the experiment
1.SH106B automatic open flash point tester, developed and produced by Shandong Shengtai Instrument Co., Ltd.
2. Open flash point special cup
Experimental steps:
First, preparation work
1. After the instrument is unpacked, please count the accessories according to the packing list. If there is any damage, please contact our company.
2. The instrument should be carried vertically, and the tilt Angle along the height of the instrument should not exceed 30 degrees. It should be placed in a dark place and placed smoothly, otherwise there will be vibration after the start of the instrument, which will affect the service life of the instrument.
3, the instrument power supply is connected to the capacity of more than 220V/10A socket, pay attention to must have a good grounding wire.
Second, the experimental process
1. After the power is switched on, the test arm of the instrument is automatically lifted to display the experimental interface.
Click "Start", and the test arm falls down to start the test;
Click "Stop" to stop the test and lift the test arm.
The "Test Conditions" section shows the test setting conditions, including the expected flash point, printer switch Settings, and the standard applicable to the test.
The "Test Information" section displays the test progress information.
In the test interface, click "Self-test", "Settings", "Conditions", "Record" and other buttons to enter the corresponding functional interface.
2. Self-check interface
Under this interface, self-check operation can be performed on each component of the instrument.
Click "Test Arm", the test arm component rises;
Click again and the test arm assembly falls.
Click "igniter", point the bright firearm;
Click again to extinguish the igniter.
Click "Stir" to start stirring.
Click again to turn off mixing.
Click "Open the lid" to start the sliding plate of the cup lid and automatically return to its position.
Click "Printer" to start the printer to print self-test. The printer will print the simulated test results (not the real test results) to verify whether the printer works normally.
During the self-test of each component, the corresponding operation information will be displayed below it.
3. Set the interface
Under this interface, you can set the estimated flash point value and atmospheric pressure value. Click "Change" after "Estimated Flash Point" or "Atmospheric Pressure" to enter the interface for setting the estimated flash point or air pressure:
Expected flash point setting
