    Lanzhou Liulian lubricating oil manufacturers remind the use of heat transfer oil precautions。

    1, to prevent impurities such as water in the heat carrier with the heat carrier heating rapid evaporation, heat conduction tube pressure rises sharply, resulting in uncontrollable degree and explosion accidents。因此,Lanzhou heat transfer oilIt should be heated slowly before being put into use to remove water and other light main impurities in the thermal oil。

    2, avoid thermal oil oxidation。Because the heat transfer oil is prone to oxidation reaction when running at high temperature in the heat carrier, the heat transfer oil deteriorates, so the high temperature expansion tank is usually set with nitrogen protection to ensure that the heat carrier system is closed, avoid the heat transfer oil and air contact, and extend the service life of the heat transfer oil。
    3, regularly test Lanzhou heat transfer oil indicators, regularly test and analyze heat carrier residual carbon, acid value, viscosity, flash point, melting point and other physical and chemical indicators, timely grasp its quality changes, analyze the reasons for its changes。When the acid value exceeds 0.5mgKOH/g, the viscosity changes by 15%, the flash point changes by 20%, and the residual carbon (mass fraction) reaches 1.At 5%, it is proved that the thermal conductivity oil performance changes。The new heat carrier is properly supplemented regularly, so that the residual carbon in the system is basically stable。

    4.When the operating temperature of the heat transfer oil exceeds the high service temperature, the wall of the oil guide tube will coking。With the thickening of the coking layer, the high temperature of the tube wall promotes the adhesion of coke, and the temperature of the tube wall further increases。With the thickening of pipe wall and the deterioration of heat transfer performance, explosion accidents may occur at any time。Therefore, the temperature of the heat transfer oil exported by the heat carrier shall not exceed the high temperature, and the high film temperature of the heat carrier shall be less than the allowable oil film temperature。

    5, regularly check the leak point, strengthen on-site monitoring, to ensure that the heat carrier system is intact, regularly check the corrosion of the equipment leakage, timely maintenance of leakage。Therefore, the heat carrier system should be reasonably designed, the wall thickness and compressive strength of the equipment should be regularly tested, and the pressure gauge, safety valve and drain pipe should be installed on the equipment and pipes。
