Cast aluminum heaters are widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemicals, rubber, petroleum and other equipment. It uses tubular electric heating elements as the heating body, bent into shape, with excellent metal alloy materials as the shell, and centrifugally cast into various shapes, such as round, flat, right angle, air-cooled, water-cooled, etc. After completion, it can be tightly bonded with the heating body, with working temperature between 300-450°C.
From the above, you have learned the detailed applications of cast aluminum heaters in daily use. Now, how much do you know about their technical indicators? If you still have a vague understanding of their technical indicators, why not take a few minutes to learn with Xu Ji Electric.
Technical indicators:
"Overheat alarm meter" is used to measure the internal temperature of this product, with a range of 0-800°C. "Pu" on the dial is the actual measured value, and "Su" is the set alarm value. During the process of setting the alarm value, if the "sel" button is not pressed, it will automatically recover after waiting for 10 seconds, and then the setting can be started from the beginning. If the instrument is shut down due to an overheat alarm during normal operation, clear the obstacle and let the temperature drop to normal, then press the "internal temperature alarm" button to reset, and then start the cast aluminum heater again.
"Temperature controller" measures the actual temperature at the outlet of the cast aluminum heater, with a range of 0-800°C. Set the heating temperature to be achieved on the dial. To resist e-402, it can be started once and then operated continuously. When starting, you can first lower the temperature, then gradually increase the set value to reach the given value, to prevent the impact of temperature rise inertia. To resist e-404, not all intermittent operations can be set each time, but only the alarm temperature can be set higher to prevent the temperature rise inertia from reaching the alarm value.
"Flow alarm meter" measures the gas flow rate flowing into and out of the instrument. The range of e-402 is 0-9999 nm3/h, and the range of e-404 is 0-8000 nm3/h. Set the lower limit alarm value on the dial. If a low flow alarm occurs, the instrument will not start.
Press the start button of the heater, you will hear the closing sound, and the instrument will start.
Press the blocking button of the instrument, you will hear the power-off sound, and the instrument will block operation.
When the instrument is running, click the emergency stop signal on DCS and confirm, the heater will block operation.
After DCS sends the emergency stop signal, you will hear the power-off sound, and the heater will block operation. If you want to start the instrument again, click the emergency stop signal on DCS to green.
