Daily cleaning and maintenance of industrial spark plugs

Update:01 May, 2025

1. Daily cleaning methods and steps of industrial spark plugs

Use a special spark plug socket wrench to remove the spark plug, and be careful to prevent foreign objects from falling into the equipment. During the initial cleaning, you can spray the carburetor cleaning agent or soak it in white vinegar to soften the carbon deposits. Stubborn carbon deposits can be cleaned with an ultrasonic cleaner and a detergent solution for 20-30 minutes to ensure that there is no residue on the electrode and the porcelain core.

2. Inspection and adjustment points

check the electrode status of the industrial spark plug: if the electrode becomes round, there are cracks on the surface, or the insulator is damaged, it needs to be replaced immediately. Use a feeler gauge to measure the gap, and adjust it if it exceeds the range. The adjustment method is to tap the outer electrode or use a tool to bend the electrode to the standard value.
Verify the working status of the spark plug through the spark test: connect the spark plug to the high-voltage wire and ground it, and observe whether the spark between the electrodes is stable.
The normal color of the electrode should be grayish white. Blackening or oily stains indicate abnormal combustion, and the equipment mixture ratio or sealing problems need to be checked.

3. Maintenance cycle and replacement standard of industrial spark plugs

It is recommended to perform a thorough cleaning after every 3000-5000 hours of operation, and shorten it to 2000 hours under frequent high temperature or high load conditions.
Mild carbon deposits can be disassembled and inspected every quarter, and severely polluted environments require monthly inspections.
Material life: Nickel alloy spark plugs are about 20,000-30,000 hours, platinum 60,000-80,000 hours, and iridium can reach more than 100,000 hours.
