Roasting cigarette igniters: reasons why igniters fail to ignite
Flue-cured tobacco igniter : the reason why the igniter cannot be ignited.
The igniter is a new type of ignition device that uses the piezoelectric effect of piezoelectric ceramics to ignite. It has the characteristics of stable output voltage, high ignition rate, durability, and novel style. Ceramics are polycrystalline made up of many tiny particles arranged randomly. Even though each small crystal has piezoelectric properties, due to the disordered arrangement of its electric moments, the piezoelectric effects cancel each other out and the whole ceramic has no piezoelectric properties.
The igniter is fixed in the middle of the gas generator. When the vehicle collides and reaches the deflagration condition, the airbag ECU turns on the igniter control circuit, and the current passes through the igniter to make the heating wire of the igniter generate heat. The resulting pressure and heat penetrate the cartridge, igniting the pressurized charge.
Flue-cured tobacco igniter : Reasons why the igniter cannot be ignited
1. The damper opening of the igniter or the chimney baffle opening is too large, resulting in too much air entering the furnace. In this case, the igniter is not easy to ignite.
The treatment method is: reduce the opening of the igniter damper and the opening of the chimney baffle, and then adjust the damper and baffle to the appropriate opening after lighting up.
2. When the fuel pressure is greater than the atomized steam pressure, the igniter is not easy to ignite.
The solution is to adjust the fuel pressure to
the flue-cured tobacco igniter : how to maintain the igniter?
1. Routine maintenance: always keep all surfaces clean; when the equipment is shut down, all rotations of the quick-opening blind plate (flange cover) should be lubricated in time according to regulations, and the lead screw of the opening and closing part should be coated with grease. Other parts should be coated with grease as much as possible. For parts that cannot be greased, 10# or 20# engine oil can be injected.
suggestions during operation The operator is responsible for the normal maintenance of the equipment; always keep the surface of the equipment clean; monitor the readings of the differential pressure gauge at any time. When the operating pressure difference reaches 0, flush the filter element.
3. Inspection cycle
Regularly inspect the equipment in strict accordance with the relevant provisions of Chapter VI of the "Capacity Regulations". Inspection and wall thickness measurement shall be carried out on the equipment at least once a year, and non-destructive testing shall be carried out on the pressure weld of the equipment every two years. All inspection and test results shall be documented in the technical documentation of the equipment. Maintenance must not be performed while the equipment is under pressure. Maintenance under special circumstances shall be carried out in strict accordance with Article 122 of the Capacity Regulations.
4. Maintenance during parking.
When the equipment is parked, the liquid in the equipment should be drained; all valves should be closed; the surface of the equipment should be cleaned; all rotating parts should be greased; all equipment should be covered with canvas to prevent dirt from depositing on the surface of the equipment.
The igniter is used to switch on or off the primary circuit of the ignition system according to the ignition signal input by the signal generator, so that the secondary winding of the ignition coil generates ignition high voltage. At present, the internal circuits of igniters used in automobiles are various in form, but their basic functions are roughly the same, and their circuits are also composed of corresponding functional circuits.
