Repair and maintenance skills for common faults of automatic image measuring instruments

Common problems with image measuring instruments include landing gear problems, console problems, projection screen problems, projection imaging problems, image imaging problems, electrical problems, electronic problems, and accuracy problems.

1. There is a problem with the landing gear. Common problems include abnormal noise during takeoff and landing, inability to rise or fall, falling sensation during landing, bouncing, large backlash during transmission, fine adjustment without transmission, and loose projection screen frame.



2. Trouble with the situation. Generally, it is easy to present symptoms such as idle running of the polished rod, bouncing of the polished rod transmission, uneven friction transmission, noisy activity of the workbench, and signs of jamming in the workbench. When dealing with a problem, it is important to find out the cause of the problem and then focus on it. Adjust the screw tightness of the spring, change the bearing, add new oil, add smooth oil, change the polished rod, adjust or replace the polished rod bracket, and other methods to handle.



3. Problem with projection screen. When there is a sound in the torsion, impurities (such as rust stains) on the end surface can be cleared and positioning bearings can be replaced. When twisting, the friction force is high. You can loosen the locking screw or change the friction rotation. When the torsion is uneven, the dial seat, friction wheel, friction wheel shaft, etc. can be replaced. When the projection screen rotates without counting, you can tighten the angle friction machine, weld the signal wire, connect the plug, and so on.



4. Projection imaging problems. "Imaging trance, dark areas in imaging, black spots in imaging, and dark light in imaging contrast can stop washing the objective lens, projection screen, desk glass, condenser, and reflector.". Stop conditioning or replacing the filament. If the lamp supply voltage is too low, install a main power regulator.

If you want to reduce the occurrence of defects in the image Measuring Instrument, it is necessary to pay attention to the daily routine of maintaining the instrument. Instruments should be stored in a clean, dry, and appropriately constant temperature room to prevent mildew on optical parts, rust on metal parts, and peeling of dust and debris. Optical components should be kept clean and should not be touched by hand. Cleaning should be stopped frequently.
