Common Faults of 26mm Large Diameter Cartridge Heater and Troubleshooting Methods

The 26mm big diameter cartridge heater is a common choice for heavy-duty industrial heating. Its reliable functioning is very important for production efficiency. But the cartridge heater often has problems when it is used, including not heating up, not heating up enough, or short circuits. This is because of things like using it wrong, making mistakes during installation, and environmental conditions. Many businesses don't know how to fix these problems, which means more downtime and more maintenance expenditures. This post will list the most common problems with 26mm big diameter cartridge heaters and give you useful ways to fix them.


The 26mm big diameter cartridge heater's most common problem is that it doesn't heat up. There are frequently three explanations for this problem: first, the power supply is broken, which could be because of a power loss, a loose power connection, or a voltage mismatch. At this point, it is important to check the power supply, make sure the power is working properly, and tighten the power connection. Also, check to see if the voltage of the power source matches the heater's rated voltage. The heater's internal resistance coil is also broken. If the resistance value is infinite, it means that the resistance coil is broken and the heater needs to be replaced. To check the resistance of the heater, use a multimeter. Third, the terminals are loose or have rust on them, which makes it hard for electricity to flow. To get the power back to normal, clean the terminals, get rid of the oxidation, and tighten the connections.

Another typical problem is that the 26mm large diameter cartridge heater doesn't get hot enough, either because it heats up too slowly or because it can't achieve the set temperature. The primary reasons are: first, the heater doesn't have enough power. If the real power of the heater is not the same as the nominal power, it could be because the voltage is unstable or the wrong power was chosen. In this case, the power supply should be adjusted or the heater should be replaced with one that has the right power. Second, the heater doesn't fit snugly in the mounting hole, which makes it hard for heat to move. If the space between the heater and the hole is more than 0.008", add thermal paste or replace the heater with one that has the right diameter to make heat transmission work better. Third, oil stains or debris in the mounting hole can make it harder for heat to move. Clean the hole where the heater goes and put it back together.

Short circuit is a more dangerous problem that can lead to electrical risks including fires and damage to equipment. The major reasons why a 26mm big diameter cartridge heater short circuits are: first, moisture gets into the heater's internal structure and breaks down the insulation. This happens a lot in places with a lot of moisture, like immersion heating. Right now, you should take the heater out, dry it out completely, and check the insulating resistance. If it doesn't satisfy the norm, you should get a new heater. Second, the insulation inside the device is damaged by too much heat. This usually happens when the working temperature is too high or the heat transmission is bad. Check the temperature and how well the heat is moving, change the operating parameters or make the heat transfer work better, and replace the broken heater. Third, the sheath is broken, which causes a short circuit inside. Look for scratches, rust, or other signs of damage on the sheath. If you find any, you should replace the heater right once.

The 26mm large diameter cartridge heater may also have problems like heating unevenly and making strange sounds. Uneven heating is frequently caused by the internal resistance coil not being evenly distributed or not fitting well with the mounting hole. You should verify the heater's internal construction or modify the fit clearance. Loose terminals or equipment vibration are the most common causes of strange noises. To fix the problem, tighten the terminals and examine the equipment vibration.

It is important to remember that only trained professionals should troubleshoot the 26mm big diameter cartridge heater, and the power supply should be turned off before use to minimise electrical dangers. Also, regular inspections and maintenance might make defects less likely to happen. If you can't fix a problem with easy troubleshooting, it's best to call the manufacturer for professional maintenance or a new part.

In short, knowing the main difficulties and how to fix them with a 26mm big diameter cartridge heater may swiftly fix problems that come up during operation, cut down on downtime, and boost production efficiency. There are different reasons and fixes for different problems, so it's important to figure out what the problem is and take the right steps. For complicated problems, you need competent technical help to make sure the 26mm big diameter cartridge heater works safely and reliably.
