What methods does the image measuring instrument have about moisture prevention?
What are the methods for preventing moisture in the image measuring instrument? We know that the image measuring instrument is a particularly accurate measuring instrument. At the same time, this kind of equipment is destined to be more delicate than ordinary mechanical equipment. This is usually a supplement to human performance that may be affected by improper operation. External accidental environmental factors cannot be ignored. These external environmental factors include ground levelness, temperature, light intensity and air humidity. There is more precipitation in most areas in spring and summer, so we must take measures to prevent moisture in the instrument storage room. There are many specific methods, such as installing a wall fan in the test room of the instrument to maintain air circulation; placing an appropriate amount of desiccant on the wall of the test room; putting a dry cloth on the artificial water inlet and outlet to prevent people from taking the water Enter the room; wipe the surface of the instrument with a dry cloth. A simpler hygrometer can be used for humidity measurement in the test room. The hygrometer usually uses a percentage to display the ratio of water molecules to gas molecules in the air. Steps to wipe the surface of the image measuring instrument: First, wipe the surface of the instrument with a dry cotton cloth or wipe off dust or oil with wipe paper, taking care not to damage the appearance of the instrument. Then use a clean dry cotton cloth dipped in industrial alcohol to wipe the instrument, especially on metal and non-metal surfaces. Steps to clean the mirror image measuring instrument: First, gently wipe the surface of the mirror with lens cleaning paper, do not scratch the surface of the mirror forcefully. Then use a cotton swab to absorb industrial alcohol, gently wipe the mirror surface, and then wait for the alcohol to evaporate before reinstalling.
In a humid environment, the image measuring instrument has no moisture-proof measures. You will find many problems when using the instrument. For example, there is a fog layer on the lens and the image is not clear; the metal surface of the instrument will breed bacteria. The rust layer makes the hand feel bad when operating the instrument. Therefore, it is necessary to keep the instrument dry and clean in this humid climate.
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.
