As a medium that transfers heat under high temperature conditions, heat transfer oil will be affected by the ambient temperature during use. Both high temperature and low temperature may cause changes in the physical and chemical properties of heat transfer oil, thereby affecting its heat transfer performance and service life. Therefore, in order to ensure that the heat transfer oil can work normally in various extreme environments, high-low temperature resistance tests are required. By simulating different temperature conditions, the thermal conductivity, viscosity, stability and corrosion performance of heat transfer oil at high-low temperatures can be tested to evaluate its applicability and reliability in various application scenarios. The development and production provide reference and guarantee.
The high-low Temperature Test Chamber is used to test the performance and stability of heat transfer oil in high temperature and low temperature environments, so as to evaluate the application range and service life of heat transfer oil. This type of test can simulate the performance of heat transfer oil at different operating temperatures to determine whether it meets the requirements for use.
experiment procedure
(1) Heat the heat transfer oil sample to be tested to a set high temperature value (eg 250°C), and keep the temperature stable for a period of time (eg 2 hours).
(2) Cool the sample to a set low temperature value (eg -30°C) and keep the temperature stable for a period of time (eg 2 hours).
(3) Heat the sample again to the set high temperature value, and repeat the above process several times to test the performance and stability of the heat transfer oil in an alternating high-low temperature environment.
(4) During the test, the parameters of the heat transfer oil can be monitored and recorded, such as density, viscosity, flash point, thermal conductivity, etc.
(5) After the test is completed, evaluate the performance parameters and stability of the heat transfer oil to determine whether it meets the requirements for use.
NBCHAO reminds you: the high-low temperature test parameters and test standards of different types of heat transfer oil may be different, and the specific test steps should be adjusted according to the product type and relevant standards. At the same time, sufficient safety measures need to be taken before the test to ensure that no safety accidents will occur during the test.
