Watch movement cleaning and injection Lubricating oil referred to as "wash oil" is a watch repair work is always very important. The purpose of washing oil is to keep the parts of the table clean and the necessary lubrication of mechanical parts, so as to ensure the precision of the parts of the mechanical parts, improve the precision of travel time of the mechanical parts and prolong the service life of the mechanical parts.
Under normal circumstances, the general table machine wash oil after two years. Under normal circumstances, oil scrubbing work is often carried out simultaneously with the adjustment and repair of parts.
In addition, check the watch machine fault at the same time, found the following problems must also be carried out when the machine wash oil work:
1. The movement of the lubricant dry or become sticky. This will increase the resistance of mechanical movement, so watch machine is not allowed to go;
2. Table too much lubricant. This will cause the oil to flow around and pollute the machine parts, especially the pollution escapement speed regulating mechanism so that the watch machine stops or is obviously not allowed to stop;
3. Movement into the foreign body, such as dust particles, metal particles, fine fibers and so on. This will result in the table transmission is blocked, so that when the watch is not allowed to go or even stop walking;
4 parts rust. This is due to the user's lack of knowledge of the protection of the watch or the use of the environment (such as underwater or aerial work), as well as poor case sealing performance, it can make the watch go wrong or stop walking.
Then after washing the oil, the watch has the following effect, indicating that the oil wash is successful.
1. Watch case and body clean, no old marks, dust and fingerprints;
2. The body is installed correctly, for example: screw tight, three-pin installation is correct, the gear meshing normal, axial, radial clearance qualified, escapement speed regulating mechanism is normal, aneroid flatness, balance does not bias;
3. The right amount of fuel, the location of the fuel should have oil, should not be refueled to ensure that no oil;
4. Two exertion when the swing reached 120 °, the full swing to 270 ° -300 °, half a full bar (ie, after 24 hours) put the swing is not less than 180 °;
5. The error of not more than 45 seconds.
