As we all know, the blast drying oven is a general-purpose equipment used in all walks of life. Due to the need to use the blast drying place, the working time is long, the equipment should be maintained in time. Therefore, we must maintain and maintain the blast drying oven in accordance with normal procedures within a certain period of time to restore its function and function. So let's talk about the maintenance methods and precautions now: (1) Before using, you must pay attention to whether the power supply voltage used is consistent. When using, the power cord on the device must be properly connected to the prepared power source. (2) Remember not to wrap the power cord around all metal objects in the oven. (3) The outer casing must be well and effectively grounded to ensure safety. (4) Perishable, flammable and explosive materials shall not be placed in the blast drying oven. (5) When placing the test sample in the working room, it should not be too dense, and the space for natural convection of the air must be left to avoid affecting the normal flow of the airflow in the working room. (6) When using the power supply, avoid touching the electrical parts of the cabinet or wiping it with a damp cloth. (7) Always check the presence or absence of overlap or short circuit of the nickel wire before use. (8) When the temperature of the drying chamber is close to the set temperature, the heating indicator light flashes and dims, repeated many times, which is a normal phenomenon. Under normal circumstances, the temperature in the working chamber enters a constant temperature state about 30 minutes after the measured temperature reaches the control temperature. (11) When the new set temperature is lower than 100 °C, the secondary temperature rise mode can be used to eliminate the temperature "overshoot" and assume 50 °C, the first time set 40 °C, and the temperature overshoot starts to fall back to 50. °C. (9) When the blast drying oven is working, the fan switch must be turned on to make it run. Otherwise, the temperature inside the box and the measured temperature are very different, and the motor or sensor may be burnt out due to the operation. (10) The box should be kept clean frequently. If it is not used for a long time, the plastic dust cover should be set and placed in a dry environment.
