5 , Production Process
1, tune the good particles through our pipeline transportation,
delivery to the granulation tower.
2, granulation tower is our unique ceramic production process - isostatic pressing technology, mainly grinding the particles with isostatic pressing technology directly dry forming, so that there is no air between the particles and the gap between the particles to ensure that Density. Isostatic technology At present, except for our industry only NGK, DENSO, champion, Bosch and the torch has a set of technology, the technology than the traditional hot melt technology, high pressure, resistance to wear, high temperature ability times several times.
3, after the formation of particles through the constant temperature tunnel kiln, which is through the natural gas calcination molding - the temperature up to 1580 degrees, higher than the engine normal operating temperature (500 degrees -800 degrees).
4, after the ceramic insulator after the glaze, make it smooth, bright. And then printed on the outside of the corresponding printing.
6 , the air gap and along the surface of the spark plug
So far, there are two main ways of spark plugs
flashover: one is the pulse of high voltage,
The spark plug (Fig. 3) strikes the air gap between the center
electrode and the side electrode to generate the spark; the other
is the flashover along the surface, that is, the discharge path is
carried out along the insulator surface between the center
electrode and the side electrode. The former discharge distance is
short, flash performance is poor, the traditional single-side spark
plug especially. Because the size of the air gap by the power
supply voltage constraints, generally 0.6 ~ 0.9mm or so. The
shorter discharge distance makes the fire nucleus not fully
"developed", the heat is also absorbed by the side electrode,
reducing the energy of the spark. If you increase the air gap, you
need to improve the ignition voltage, easy to lead to "fire." The
surface discharge occurs at the interface between the surface of
the insulator and the surface of the air. The distortion of the
electric field on the ceramic surface increases the local field
strength, resulting in local discharge, which leads to further
development of the discharge until the electrode gap breaks down.
This discharge mechanism reduces the breakdown voltage along the
surface gap with the width of the air gap. If the same breakdown
voltage, along the gap than the air gap discharge distance. A
longer discharge distance can greatly increase the energy of the
spark. Because the spark discharge is composed of two very
different energy densities, the capacitive discharge section and
the inductive discharge section. The former has a high energy
density, high voltage, can be released in a very short time; the
latter energy density is small, but in a long time work. From the
EDM energy distribution can be seen in the part of the energy of
the capacitor part of the capacitance of 20 to 30 times, is a
veritable "hot flame", the heating around the formation of the main
role of the formation of fire. The longer the inductive part lasts,
the better the fire. The extended discharge distance will reduce
the "flaring effect" of the side electrode. EDM along the surface
of the insulator burning oil coke, to avoid the interconnection
between the electrodes, but also to avoid the insulation between
the insulator and the shell caused by the phenomenon of leakage
caused by leakage, to ensure the idle conditions of ignition
reliability. The interstage-type spark plug insulator has no skirt,
can not quickly absorb the heat of the combustion chamber, is a
very cold spark plug. The wider use of the "gap" and "air gap"
together with the "sliding - air gap" between the insulator skirt
and the side of the electrode is the air gap. When the flash sparks
from the insulator surface "slip" and then jump to the side of the
electrode. The breakdown voltage is reduced due to the electric
field distortion of the insulator surface. The insulator of this
spark plug has a normal skirt so that it can accommodate different
heat loads.
