We can classify failures into eight categories: 1. Lifting drive failure 2. Worktable failure 3. Projection screen failure 4. Projection imaging failure 5. Imaging imaging failure 6. Electrical failure 7. Electronics 8. Accuracy
How to do this job has a guiding role for the customer. Doing this job can ensure the original accuracy of the instrument and prolong the service life of the instrument.
1. The instrument should be placed in a clean and dry room (20 °C ± 5 °C at room temperature, 60% lower humidity, to prevent mildew on the surface of optical components, metal parts rust, dust debris falling into the instrument guide, affecting the optical system imaging quality and Instrument measurement accuracy.)
2. The surface of optical components should be kept clean and can not be touched by hand. The dust can be wiped off with a soft brush. If the surface stains are more affected, use a cotton wool or wipe paper to dip a small amount of alcohol and ethyl ether mixture to gently wipe.
3. The projection screen is a matte surface. When you use it, try to avoid touching it. If you use it for a long time, there will be dust and oil on the projection screen, which will affect the sharpness of the image. At this time, clean the entire projection screen with a clean wet gauze, a little neutral detergent, and wipe it several times with dry gauze.

Remedy
BenchA. Light rod idling
Frictional spring contact with mechanical lockB. Boom rods have bouncing
1. The bearing in the transmission group is damaged. Replace the bearing. 2. The surface of the polished rod is scratched or stained. After cleaning, it is cleaned. 3. The polished rod is worn out. Replace the polished rod.C. When the friction drive is not smooth
1. The compression spring overtightens the screw that loosens the compression spring. 2. The polished rod is not parallel to the table motion. Adjust the polished rod support so that it is parallel.D. Workbench movement sound
1. Cage bend adjustment cage or replacement 2. There are stains in the guide rails and then re-oil after scrubbing 3. Guide rails are free from lubrication oil plus lubricantE. Blocking in the table movement
1. Lubricant free from lubricantProjection screen
A. Rotation with sound
1. The end face of the dial seat has recesses to clean the impurities on the end face, such as rust stains 2. Locating bearing damage Replace the bearings with new onesB. Large friction when rotating
1. Micro-adjustment mechanism does not rotate to loosen the locking screw, or to change frictionC. Uneven rotation
1. Dial holder elliptical renewing plate seat 2. Friction wheel elliptical renewing friction wheel 3. Friction wheel shaft wear Renewing the grinding wheel axleD. Projection screen rotation does not count
1.Angle friction mechanical loosening and re-tightening 2.Signal line contact is not good or disconnected and re-weldedLifting drive
A. There is abnormal noise in lifting
1. The timing belt is loose, and the belt tension is not synchronized with the synchronization pulley. Or the belt is replaced. 2. The helical gear wear is used to change the helical gear. 3. The screw has impurities and cleaned. 4. The structure is reported to be improved.B. Can't rise or fall
1. Helical gear stuck adjustment Helical gear screw or replacement 2. Screw stuck adjustment screw fixing screw or replace 3. Iron block adjustment clearance too thick adjustment Z axis screw 4. Unreasonable structure improvementC. Falling feeling of falling, bouncing
1.Large clearance between rail block adjustments. 2.Adjustment of loose screws between the screw and nut gaps. 3.Adopting the Z-axis rails with poor machining accuracy. New Z-axis 4.Unreasonable structure improvement.D. Large backlash in transmission
1. Screw nut clearance large adjustment clearance 2. Screw shaft end locking screw Loosen pinning screw 3. Two helical gears clearance Large exchange helical gearE. Fine-tuning the drive
1. Friction transmission mechanism Compression spring Loose compression spring or renew spring 2. Drum seat cylindrical surface is oily and slippery Clean the oil with a cleaning fluidF. Loose projection screen
1. Locating the bearing and the clearance of the dial Large displacement limit block 2. Positioning slot clearance of the dial holder Large locking screwProjection imaging
A. Imaging blur
1. The objective lens is greased with a clean, dust-free alcohol 2. The mirror lens wears back to the factory for renewing the lens 3. The projection screen is greased with a neutral washing liquid to clean the projection screen 4. The table glass is scratched to replace the new table glass.B. Imaging has dark areas
1. Foreign matter or oil dust in condenser The foreign matter is wiped off with a clean cotton cloth 2. The filament is not replaced by the filament in the centerC. Image has dark spots
1. Dust and impurities in the objective lens are returned to the factory for maintenance and re-cleaning 2. Dust impurities in the mirror are cleaned 3. Impurities or damage to the glassD. Imaging contrast light dark
1. Condenser dirty or dusty Cleaning Condenser 2. Lamp power supply voltage is too low Install the mains voltage regulator 3. Filament like blur or not readjust the filament in the centerImaging imaging
A. Display black screen
1. The monitor has no power supply. Reconnect and plug in the power cord. 2. The cross-line generator has no power. Check the power supply voltage with a multimeter and change the power board.Double Worktables Fully Automatic Vacuum Forming Machine
