How to maintain the service life of thermal oil boilers

⒈ thermal oil boiler heating part should be fully immersed in the heating medium, to avoid the heat does not radiate quickly and exceed the allowable heating temperature so that the thermal oil boiler damage. In addition, the wiring lead part should be exposed in the heater insulation or outside the heater, so that this part should not be overheated and damaged.

Peck input power supply, the voltage should not exceed 10% of the rated voltage indicated on the various thermal oil boilers, such as applying to less than the rated voltage, the heat generated by the thermal oil boiler will also decline.

⒋ thermal oil boiler terminals, in the wiring should be 2 nuts relative fastening, do not force too hard to avoid the lead screws loose and make the thermal oil boiler damage.

Singing oil-conducting boiler terminals should be kept clean and dry, otherwise it will reduce the insulation properties and short-circuit breakdown, if the application of chemical corrosion, flammable, explosive and other liquids or gases in the environment, should be part of the wiring of the thermal oil boiler with an insulating sealing device to protect against accidents.

Be careful when heating some viscose and other substances, such as sodium nitrate, stearic acid, paraffin, etc., the beginning of heating should reduce the power supply voltage to reduce the heat of the heat transfer oil boiler, to be all melted into a liquid, and then rise to the rated voltage for heating.

Selective selection of thermal oil boiler should pay special attention to the heating medium. Heat transfer oil boiler shell materials should be no erosion.

Borrow thermal oil boiler use for a long time, if the surface gathered thick tube scale, grease scale, should be removed periodically, otherwise it will reduce the heat transfer performance of the thermal oil boiler caused by the surface of the tube heat load in excess of the rated permissible and damaged.

The thermal oil boiler should be stored in a dry warehouse, and if the surface becomes damp as a result of prolonged standing, the insulation resistance should be measured with a megohmmeter. If this is less than 1 megohm/500 volts, the heat transfer oil boiler should be dried in a 200 degree oven.

µ µ special thermal oil boiler should be installed and used before reading the instructions to avoid damage.
