Common Failures of 1300mm Extra-Long Cartridge Heater and Their Solutions

The 1300mm extra-long cartridge heater is commonly used in large-scale industrial heating situations, and it is important for production progress that it works well. The 1300mm extra-long cartridge heater is likely to fail in a number of ways since it has been running for a long time, is in a hard working environment, and is not being used correctly. If production sites know what typical problems are and how to fix them, they can rapidly troubleshoot and get back to work, which will cut down on losses caused by heater failure.

Heater burnout is one of the most prevalent problems, and it usually happens for one of three reasons: dry fire, too much wattage, or a voltage mismatch. Dry fire is the most typical cause. Powering the 1300mm extra-long cartridge heater without contact with the heating media (such air exposure) can quickly raise the temperature over the heating coil and insulation's ability to handle it, which will cause burnout. To fix the problem, make sure the heater is completely submerged in the heating medium before turning it on. Also, add a temperature sensor to keep an eye on the temperature in real time. If you see dry firing, turn off the power right away.

Another reason why heaters burn out is too much watt density. The watt density of the 1300mm extra-long cartridge heater should be kept between 5 and 7 W/cm². If the watt density is too high, the heating coil will get too hot and burn down because it can't get rid of the extra heat fast enough. The answer is to swap out the cartridge heater for one with a lower watt density that works for the situation. Based on experience, lowering the watt density to the right level can not only keep the heater from burning out, but it can also make it last longer.

A heater might potentially burn out if the voltage is not right. If the actual supply voltage is higher than the rated voltage of the 1300mm extra-long cartridge heater, the power will go up, which will cause the heater to overheat and burn out. If the voltage is too low, the heater won't work as well and may not achieve the right temperature. Before installing the heater, check the supply voltage to make sure it matches the heater's rated voltage. Put in a voltage stabiliser to safeguard the heater if the voltage is not stable.

Electrical leakage is another typical problem that happens when moisture gets in, insulation becomes damaged, or the sheath rusts. Moisture getting into the magnesium oxide insulation will produce electrical leaks, and corrosion of the sheath will cause pinhole leaks, which will let the heating medium inside the heater and harm the insulation. To fix the problem, you should examine the sheath for damage or corrosion on a regular basis, replace the heater when it breaks, and make sure the terminals are properly sealed so that moisture can't get in. If you find any electrical leaks, turn off the power right once and check the heater thoroughly.

The 1300mm extra-long cartridge heater also often has problems with uneven heating. This is usually because the heated object doesn't make good contact with the heater, the heating coil isn't evenly distributed, or dirt builds up. Poor contact will let heat to escape in some places, which will make the heating uneven. Uneven placement of the heating coil will cause overheating or not enough heating in some places. Accumulation of debris will make heat transfer less effective. To fix the problem, you need to move the heater to a better spot, wipe up the debris in the drilled hole on a regular basis, and use cartridge heaters with heating coils that are evenly spaced.

Another common problem is damage to the lead wire. Friction, high temperatures, or corrosion can easily damage the lead wire of the 1300mm extra-long cartridge heater, which can cause poor contact or electrical leakage. Check the lead wire often, replace it when it breaks, and put ceramic bead insulation on lead wires that are exposed to high temperatures to keep the insulation from melting.

In short, the 1300mm extra-long cartridge heater often fails because it burns out, leaks electricity, heats unevenly, or damages the lead wire. If you use, maintain, and install these things correctly, you can avoid most of these problems. If something goes wrong, following the steps above can rapidly get the heater back to normal. If on-site staff can't fix a complicated problem, they should get professional technical help to prevent losing further money.
