The working principle of the three forms of buble level
1. The working principle of the frame bubble level meter:
The frame-type bubble level is a square general-purpose angle measuring instrument that uses the principle of liquid flow and liquid level to directly display the slight inclination angle relative to the horizontal and vertical positions with the level bubble.
When looking for the level of the frame-type bubble level, it should be staggered by 90 degree for calibration, that is, the usual calibration of the X-axis and Y-axis. During the adjustment process, the water bubble should be in the middle position to meet the requirements. The spirit level also has a V-shaped groove on the side, which is used to measure the vertical surface, and the method is the same as above.
Це повинен бути зазначений що рівень повинен бути легко розміщений на поверхня до бути виміряний коли в ін використову, і спроба не до зіткнення з іт, so as to уникнути зміщення of the механічне коригування частини всередині рівень і причина неточна точність.
The accuracy of the frame-type bubble level is 0.02/1000mm, that is, 2C per meter. Each grid on the above scale is 2C, that is, every deviation of one grid means that one end is higher than 2C within one meter.
2. Робота принцип з смуга бульбашка рівень метр%3а
It consists of two parts, the V-shaped bottom plane as the working plane and the level (commonly known as bubble) parallel to the working plane. The straightness of the working plane and the parallelism between the level and the working plane are well done. When the bottom plane of the spirit level is placed at an accurate horizontal position, the air bubble in the level is just at the middle position (that is, the horizontal position). On both sides of the engraved line at the two ends of the bubble in the glass tube of the vial is the zero line, there are not less than 8 scales engraved, and the interval between the engraved lines is 2mm. When there is a slight difference between the bottom plane of the level and the horizontal position, that is, when there is a difference between the two ends of the bottom plane of the level, the bubbles in the level always move to one side of the level due to the effect of gravity, which is the level of the level. Principle of use. When the heights of the two ends are about the same, the bubbles will not move much.
The смуга рівень is mainly used to test the straightness of напрямні рейки of various machine tools and other types of обладнання and the горизонтальний і вертикальний позиції of обладнання установка. it can al al be applied to the measurement of small angles and working surfaces with V-подібні пази. It can also measure the installation parallelism of циліндричні заготовки, as as as the горизонтальні і вертикальні позиції of the монтаж.
3. Робочий принцип з складений зображення бульбашка рівень:
The combined image level uses a prism to magnify the gas and vapor in the level to growth the accuracy of the reading, and uses a set of transmission механізми uch as a важіль і a мікропереміщення гвинт to збільшення the чутливість of the читання. Тому, when the measured part is tilted by 0.01 mm/m, it can be read out in the combiner. (In the combined image level% 2c the level mainly plays the role of pointing to zero.)
