HCH deep groove ball bearingNon destructive testing method
The non-destructive testing of HCH deep groove ball bearings refers to the detection method of bearing defects and physical parameters using some principles and techniques without damaging the performance of the bearing. The biggest advantage of this detection method is that:
One is the comprehensive inspection of bearings;
Secondly, its testing will not affect the performance of the bearing;
Thirdly, this measurement method can be integrated throughout the entire process of product production.
When conducting non-destructive testing on bearings, Huanchi Bearing Company mainly uses methods such as ultrasonic testing. Below, we will provide a detailed analysis of the working principles and other aspects of these detection methods.
1. Ultrasonic testing method
Its principle is to use the propagation performance of ultrasonic waves to detect bearings. This is because once there is damage inside the bearing, the propagation of ultrasonic waves will undergo certain changes. Therefore, this technique of detecting whether there is damage to the internal structure of HCH deep groove ball bearings by observing changes in ultrasonic waves is called ultrasonic testing.
2. Penetration testing method
The so-called penetration testing refers to the process of using the action of penetrant to penetrate into the interior of the bearing in areas such as cracking on the working surface of the deep groove ball bearing, and then using a developer to suck the penetrant that has already penetrated into the bearing into the working surface of the bearing. This allows for clear observation of the existence of defects in the bearing. The biggest feature of this method is its intuitiveness.
3. Radiographic testing method
Radiographic testing utilizes the penetrability of radiation. When using radiation for non-destructive testing of HCH deep groove ball bearings, the penetration intensity of the radiation will gradually decrease due to the hindering effect of the bearing material. This intensity change will be directly reflected on the X-ray film through the photosensitive effect. In this way, the damage to the bearings can be checked through imaging records on the film.
4. Magnetic particle testing method
Magnetic particle testing is a method that utilizes the magnetization effect of magnetic particles to reveal the damage of HCH deep groove ball bearings.
This detection method is generally suitable for inspecting the surface and other positions of ferromagnetic materials, as well as some bearing raw materials.
