Penyelenggaraan proses daripada air duct pemanas

Sebelum menggunakan the air heater, the water valve should be opened to ensure that the valve body is filled with water medium. Electric heating can be used when the pressure is not greater than the working pressure.

2. If the resistance wire continues to be used after multiple repairs, it may cause the circuit to be too negative. Therefore, it is not allowed to place flammable and explosive materials near the electric heater during use, and a certain safety distance should be maintained; But it is recommended not use cables that have undergone multiple repairs, and to replace them in a timely manner.

3. After using explosion-proof air duct heaters in winter, we should promptly dispose of and discharge the water in the bucket to avoid freezing and affecting students' next use.

4. In the absence of a duct heater, the power, water source, and bucket water should be turned off for a long time.

The electric heating wire must be installed properly, and the plug cannot be directly inserted into the plug. If the electric heating wire is aged or damaged, it should be replaced in a timely manner. If the electric heating wire is not installed in the circuit, the fuse volute should not be used.

6. Kerap check the grounding of the air duct heater to prevent electric shock caused by poor grounding of the instrument. There is an M12 grounding terminal at each diagonal end of the sled base, which should be reliably grounded. Before starting, a 500V megohmmeter should be used to check the insulation resistance between the power terminal of the electric heater and the ground, which is u003E u003E20M megaohms (it can be used if it is greater than 1.0 megaohms).

7. Regularly inspect the circuit design of the air duct heater to prevent power leakage, electric shock, and fire. Carefully analyze and inspect the insulation of the cables, check if the input voltage data of the power supply is normal, and recheck whether the electrical wiring method is accurate.
