Image measuring instrument maintenance and troubleshooting
Image measuring instrument maintenance and troubleshooting 1. Cleaning and maintenance If you want to reduce the failure of the two-dimensional imager, you must pay attention to the daily maintenance of the instrument. The storage environment of the instrument is very important. It should be placed in a clean and dry room to avoid mildew on the surface of the optical parts, rust on the metal parts, and fall of dust and debris. The surface of the parts should be kept clean, do not touch with your hands, and should be cleaned frequently. 2. There is no image in the image area. If the image is gray, it may be that the video capture card is incorrectly inserted. Please turn off the computer and the instrument normally, unplug the power plug, then open the main box, take out the video capture card, and then re-insert it to confirm Is plugged in, and then start the computer. If the slot is replaced, the driver must be reinstalled. Or the driver of the video capture card is not installed, please reinstall the driver in the video card driver manual according to the installation method or the parameter settings of the video capture card are incorrect. Click the menu Image — Video Video Settings..., or click the right mouse button in the image display area, and then select Video and Video Settings... from the pop-up menu to pop up the image settings dialog box. Set the correct brightness, contrast and other parameters. 3. The projection screen is malfunctioning. It makes a sound when rotating, it can remove impurities such as rust on the end face, and replace the positioning bearing. When rotating, the friction is large, you can loosen the locking screw, and you can also change the friction. When the rotation is uneven, you can replace the dial seat, friction wheel, friction wheel shaft, etc. When the projection screen rotates without counting, you can tighten the angle friction device , Welding signal wires, connecting plugs, etc.
4. Projection imaging fails. The image is blurred, the image has dark areas, the image has black spots, and the image contrast is dark. It can clean the objective lens, projection screen, workbench glass, condenser, mirror, etc. Adjust or replace the filament. If the lamp power supply voltage is too low, please install a universal power regulator.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
