With the continuous progress of our scientific research, the performance of zirconia ceramic cylinder liners is also constantly improving, and the application scope is also expanding.
Zirconia ceramic cylinder liner is an abbreviation for zirconia ceramic cylinder liner, which is embedded in the cylinder body of the cylinder block and forms the combustion chamber together with the piston and cylinder head. Zirconia ceramic cylinder liners can be divided into two types: dry zirconia ceramic cylinder liners and wet zirconia ceramic cylinder liners.
The zirconia ceramic cylinder liner that does not come into contact with the back cooling water is a dry zirconia ceramic cylinder liner, while the zirconia ceramic cylinder liner that comes into contact with the back cooling water is a wet zirconia ceramic cylinder liner. Zirconia ceramic cylinder liner has a simple structure, thin thickness, and easier processing. Zirconia ceramic cylinder liners come into direct contact with cooling water, which is beneficial for engine cooling, miniaturization, and lightweighting.
The main processing flow of zirconia ceramic cylinder liner is cylinder barrel: cutting rough turning heat treatment (quenching and tempering) turning (flat chamfering) inner hole rough pushing inner hole rolling turning (cylindrical opening) inner hole stopper. I believe that with the continuous advancement of our technology, the performance of zirconia ceramic cylinder liners will be continuously improved, and their applications will become more widespread.
With the continuous development of various industries, zirconia ceramic cylinder liners have gradually been widely used. So in the application process, deformation of zirconia ceramic cylinder liner is an important problem that troubles drivers. Today we will introduce several methods for detecting deformation of zirconia ceramic cylinder liners:
Zirconia ceramic cylinder should be inspected using a tester: the main pin holes and spring seats at both ends of the tester are used as positioning inspection benchmarks. Fix the instrument on two leaf spring seats, insert the inspection rod into the two main pin holes, and operate the instrument to make contact between the measuring head and the inspection rod. By using different scales, the mutual position (angle) between the main pin hole and the leaf spring seat, as well as between two leaf spring seats, can be reflected. Check and determine the location and degree of deformation. Please refer to the instrument manual for specific methods and usage steps. Place the front axle on the two V-shaped irons on the flat plate and place the level gauge on the steel plate spring seat. If the level is placed horizontally (perpendicular to the front axle) and the bubble is not in the center, it indicates that the front axle is twisted; If the bubble is not centered when the level is placed vertically, it indicates that the front axle is bent.
Use a square ruler to check the zirconia ceramic cylinder: insert the test rod into the main pin hole, place a shim on each of the two steel plate spring seats, and place a square iron on the shim. The angle of the square iron should be adjusted and fixed within the specified range of each model. Then, let the square stand upright and the edge shell occupy the test bar to find the result. If there is a gap at the upper end, it indicates that the front axle is bent downwards, and if there is a gap at the lower end, it indicates that the front axle is bent upwards. In addition, whether the front axle is bent or twisted back and forth can be determined by the alignment of the line between the square and the pad, as well as the alignment between the square and the test bar.
3. Cable inspection for zirconia ceramic cylinder: Place the front axle in a horizontal position, draw the center lines of two steel plate springs, hang a heavy hammer at both ends of the line, and thread the lines through the centers of the two main pin holes. Measure the distance between the plane of two leaf spring seats and the straight line with a ruler, and the difference between the two is the straightness of the crossbeam. Check if the centerlines of the two cable sockets are on the same straight line. Check if there is any deviation in the distance between the positioning center holes of the two seats and the straight line. If there is a deviation, it indicates that the beam is distorted. Check the distance between the inner end of the plane on the main pin hole and the straight line. If there is an error between the two distances, the angle of the main pin is incorrect. Measure the distance between two leaf spring seats and the thin wire with a ruler. If they are not equal and the centers are not on the same straight line, it indicates that the two ends of the front axle are bent up and down, or bent forward and backward.
