Electrical heater Processing | Qing Li thermal equipment (certified) | electric heaters provided by kamikaze Plastic Co., Ltd. in Guangzhou. Plastic Co., Ltd. Guangzhou Kamikaze (www.gzqingli.com/index.html) is specialized in the "magnetic refrigerator, magnetic tablet" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Mr. Shen. This product is framed wall structure, equipped with over-temperature protection device, such as the heating temperature is above and> 120 ℃, shall be provided with thermal insulation zone or area between the junction box and heater, electric heater element and the surface should be located fin heat sink structure, low, medium temperature setting without duct heater or radiator heat zone electric heater element surface area and natural cooling, electrical control and oil heater fan must linkage process, start fan then start electric heating , a power failure after the first fan heater off, the time difference must be greater than 2 minutes. Control. Between the fan and heater set up a linkage to ensure the heater duct heater processing required to start work after the fan, heater stops working after electric heaters, fans must be delayed more than two minutes to prevent overheating and damage to the heater. Troubleshooting a: Power LED is not lit, the DRO does not work, no indication voltmeter. Check the air switch is closed, the control circuit fuse is intact. Failure II: heater temperature does not rise. With an oscilloscope to check whether the output trigger pulse waveform, digital temperature regulator whether the PID output. Failure three: Unbalanced with dual trace oscilloscope is triggered and the trigger pulse voltage waveform can be controlled silicon phase, can trigger pulse phase shift 120 °. Open air heater shield ceramic electric heater processing, use a multimeter to check whether the disconnection of single heating element, and then use a wrench for supporting replacement, the replacement should be careful not to damage the rubber gasket. Main products: heat processing, radiator processing, electric heater processing, condenser processing, electric heater exhaust pipe processing, high-temperature processing of electric heaters, air-conditioning duct electrical heater processing, electrical heater processing , plate heat exchanger equipment, welcome to inquire order.
