Pelbagai operasi itu perlu kepada be diperiksa for suhu tinggi explosion-proof elektrik pemanas

Sebelum menggunakan the high-temperature explosion-proof electric heater, the nitrogen pipeline should be unobstructed. The user needs to connect the power supply of the main circuit and control circuit, and connect the control circuit in the on-site operation box to the control circuit in the power cabinet.
It is necessary to check the various operations of the high-temperature explosion-proof electric heater:
Check the connection of the power supply, electrical insulation, and heating equipment of the high-temperature explosion-proof electric heater control system, and check whether the three-phase resistance of the electric heater is balanced.
Check whether the terminal connections of the control electric heater for high-temperature explosion-proof electric heaters are secure to prevent loosening and ignition.
Check whether the installation, support, and thermal expansion allowance of all equipment and pipelines in the high-temperature explosion-proof electric heater system are reasonable; The installation and acceptance results should comply with relevant national requirements.
Check whether the pressure test blind plate of the high-temperature explosion-proof electric heater pipeline system has been removed, whether various valves are flexibly and reliably opened, whether the connecting bolts are tightened, and whether the sealing is tight. Perform a pressure test on the system pipeline until the nitrogen outlet pressure fluctuates smoothly and there are no leakage points in the system.
Check whether the electrical control system, instruments, and installation of the high-temperature explosion-proof electric heater meet the requirements: whether the display of each alarm device, control system, sensors, and instruments correspond, are correct, and meet the requirements of process heating.
Check whether the pipelines and valves of the high-temperature explosion-proof electric heater are normal, open the pumps, pipelines, and valves, and ensure that there are no other safety hazards that endanger the operation of the heater on site.
