In the use of process equipment, electric heating pipe does not work often encounter problems, do not understand or just come into contact with people in the industry, does not meet the causes of fever electric heating tube, heating rod that is bad, some do not know what the problem is, go blind for procurement for heating tube manufacturers purchase, in fact, when the electric heating tube is not heating situation, should be timely investigation of the problem, and then an antidote against the disease to solve problems. This can not only save the cost but also can know the problem and avoid similar problems from happening again.
The electric heating tube heating is not for a variety of reasons. Some problems of its own electric heating tube or not heating tube own problems. We put some common and simple explanation and under:
1 off all the peripherals circuit, with a multimeter ohm range, suitable range, measuring whether there is resistance, the resistance value without a strong, determined to open, the heating wire is disconnected; if the resistance value, approximate and “voltage * voltage / power” the impedance value, heating tube normal;
2 electric heating tube especially industrial electric heating tube in the use process is convenient to control so on the electric heating tube is installed above a adjustable temperature control so as to regulate the temperature of the electric heating pipe temperature control is called. The electric heating tube heating may not bad contact is the thermostat contacts or melt away. If the replacement of adjustable temperature controller to replace a broken, if or not, is the electric heating tube for the need to buy.
3 electric heating tube without heating, electric heating tube 80% sure is normal, it should start from the supply side started the investigation first to determine whether a power outage or plug is inserted to forget, plug and socket contact is good. Sure everything is normal if the electric heating tube is not working, that electric heating tube is bad.
4 electric heating tube is not working is not heating, electric heating pipe heating pipe inspection, found lead or lead off. Turn off the power immediately. The electric heating pipe leading sheet or wire welding. Turn on the power, are all normal.
