Common sense of use and maintenance of oil heaters
I. Correct use of temperature Controller
The electric oil heater is equipped with a thermostat, so that the surface temperature of the heater shell can be adjusted at will (below 110℃). During normal operation, the thermostat should not always be set to the highest level, otherwise, when the working temperature of the heater surface is close to 110°C, the thermostat will not be easy to operate, and long-term high temperature operation will easily burn out the internal components or damage the protection. Therefore, when using the electric oil heater for the first time, the thermostat should be set in an appropriate position. When adjusting, first turn the thermostat knob clockwise to the maximum position, turn on the two-speed power switch, the whole machine is in the maximum output state, heat up for about 5 minutes, and lightly tap the upper surface of the shell with the back of the hand. Feeling that the temperature is suitable, turn the knob counterclockwise slightly until there is a crisp contact popping sound, and the power indicator on the power switch is off, and then turn it clockwise to a small angle, so as not to make the contact Click to close. After this setting is completed, the heater can provide people with a satisfactory temperature. When the shell surface is slightly hot, the temperature is about 85°C. When the temperature of the heater shell is higher than the set temperature, the thermostat will automatically cut off the power supply to stop heating, and the heat stored inside will continue to be released outward. When the surface temperature drops by 15°C, the contacts of the thermostat will be automatically closed, and the heating will be heated up when electrified. This cycle is repeated, the temperature is stable.
Second, the correct choice to use the power switch
The electric oil heater adopts two sets of sealed electric cathode heating tubes as heating elements, and the two sets of heating tubes correspond to There are two selector switches for two grades. At present, the common heaters on the market are 1500W and 2000W. Under the conditions allowed by the standby line, the correct selection of the power gear can save electricity and reduce the line load. When the heater starts to be turned on or the indoor temperature is low, turn on the two gear selector switches at the same time, the heater heats up rapidly, and when the working temperature of the shell surface reaches the set temperature point, the thermostat will automatically cut off the power supply. At this time, gear 1 or 2 should be selected. gear power. When the thermostat is reset and energized, it uses lower power to heat and gradually increase the indoor temperature.
Third, pay attention to maintaining the airtightness of the room
The electric oil heater raises the indoor temperature in the form of air convection. It also affects the on-off of the power supply. The indoor airtightness is good. After the room temperature rises, the heating time is short and the heat dissipation time is long, thereby saving electricity.
4. Prohibition of covering
The heater is working normally, and the surface temperature of the shell is relatively high, generally set at about 90℃. The temperature control of the heater is realized by the temperature deformation of the thermostat metal sheet in the mask. If you wrap the heat sink around the heat sink for baking clothes, the temperature of the covered heat sink will be significantly higher than the temperature felt by the in-plane bimetal, which will easily burn the clothes, and may cause the heat conduction element inside the heater shell damage. 5. It is forbidden to turn upside down or put down the electric heating
The heater shell is filled with special heat transfer oil. After heating, there is a certain pressure inside. In order to ensure that the internal pressure is lower than 0.2Mpa during normal use, the heat transfer oil fills up About 70% of the total volume, there is a large space inside. Upside down or put down, the internal heating tube is exposed to the oil surface. In this case, the heating may cause overheating and bursting and damage the heating tube. In this case, be careful when using it.
