1.And can't spend hot technological requirement is the correct to select for use heat conduct oil of at various kinds of trade mark energy-conservation the trade marks of oils, And strictly observe every regulation in" act of technique for security of heating furnace of hot body of year" of the Ministry of Chemical Industry, Use the heat conduction oil correctly.
2. check conscientiously,the waterproof, sour, alkali and low boiling point thing leak and enter system of using of and not adding and install and for device tight, Prevent mechanical incidentals from entering, guarantee the purity of the oil.
3. energy-conservations heat conduct suitable for fire coal of at oils, act as hot body year at fuel heating furnaces,it doesn't react and wait for equipment heat supply that electricities heat, While using, should expand poor and store the trough and other safe packages and accuse of auxiliary facilities, such as instrument,etc. warmlily , Guarantee the safe operation.
4. change new heat conduction at the time of oils by equipment,must wall incidental in not dispelling, So as not to influence the biography thermal efficiency and service life of the heat conduction oil.
5. Come into operation at heat conduction oils,it start first circulation run to half an hour of oil pumps when not running, Light a fire and intensify again, should intensify and nearly promote 20 ℃ per hour slow while using for the first time, Rise to ℃s when the about ℃s, want and keep warm period and rise to ℃s keep warm some time put into and use normally at the ℃s as temperature as temperature.
6. high temperatures by using to half a year in heat conductions oils, carry on analyse at times of oil. After ifing long run, find that result of conducting heat is bad, or finds the unusual situation, Should last decision from oil( it is mainly last project , incomplete charcoals, quite at 1.5%, acid values quite at 0.5 mgKOH/g, It change flash points quite at 20%, viscidities there is quite at 15% changes) consider and add by some new oil or last new oil all.
7. forbid of not running it to exceed is warm to use,guarantee the normal service lives of oils heat conduction.
8. follow above-mentioned points for attention safety in operations at users.
