What is the level bubble like? How to operate?

Pingpu includes more than 300 specific models such as ordinary type, box type, compensation type, glass type, metal type, electronic type, electronic compensation type, plastic level bubble, etc. The products with an angle of 60'2mm-2 '/2mm are widely used in photoelectric equipment such as theodolite, water cannon, compass, electronic scale, total station, etc.

The accuracy of the floor marking circle is also referred to as the angle value. For a round level bubble, the accuracy represents the slope of the level bubble when moving 2mm along an arbitrary radius in the middle of the split line. For longer level bubbles, the accuracy indicates the degree of tilt of the level bubble as it moves 2mm along the axis of the level bubble.

The measurement value is read by the bubble movement of the level bubble having a curvature radius on the inner wall of the glass tube. After the water gauge is tilted, the bubble moves to the rising section of the water gauge. The radius of curvature of the inner wall of the bubble determines the accuracy of the instrument.

Liquid level bubbles are mainly used to detect the straightness of various machine tools, construction machinery, textile machinery, printing machinery, mining machinery and other equipment guides and the accuracy of the horizontal and vertical positions of installation.

When the standard light source frame level bubble of the headlamp tester corrector is set in the middle position, and the upper, lower, left and right positions are all set to 0, the emitted light beam directly enters the headlamp tester under test, and the upper, lower, left and right positions of the instrument are also set to 0. Theoretically, the value is higher, and the position of the machine beam overlaps with the position of the actual beam. ideal state. In other words, when the middle position of the light matches the position of the mechanical light, only the height from the middle of the light box to the floor needs to be measured.

Due to the error generated by machining and the systematic error generated by the whole instrument debugging, the position of the mechanical beam is difficult to match the position of the actual beam, so the concept of the method to determine the middle position of the beam is produced.

First, place the headlamp corrector to be checked in one position, and carefully adjust the three eccentric bolts of the support leg so that the level bubble is in the middle position when the headlamp corrector of the column is in the front, rear, left and right positions. Then move the left, right, upper and lower positions of the headlamp corrector until the light intensity reading is large, which is the middle position of the light column, and the readings of the left, right, upper and lower positions are the deviation of the instrument itself. The height value measured by the altimeter (or other measuring tool) is then the actual midpoint height value of the light column. This reading is usually different from the scale of the column. The scale on the column is the height of the middle of the beam to be measured during inspection.

Pingpu includes 300 specific varieties such as ordinary type, partition type, compensation type foam type, glass, metal, electronic water cannon, electronic compensator, plastic liquid level cannon, etc. The angle value is 60'2mm-2 '/2mm. Theodolite, level meter, compass,

The accuracy of the floor marking circle is also referred to as the angle value. For circular floor marking circles, the accuracy indicates the slope of the floor marking circle when the marking circle moves 2mm from the center of the line of differentiation to any radius. For the long elevation number, the precision indicates that the slope of the scale height number when the number moves 2mm along the horizontal number axis. The level bubble level meter reads the measured value through the movement of the bubble in the level bubble with a certain curvature radius on the inner wall of the glass tube. When the level meter is inclined, the bubble moves to the rising end of the level meter, and the curvature radius of the inner wall of the level bubble determines the measurement reading accuracy of the instrument.

Use elevation bubble elevation:

It is mainly used to check the track smoothness of various machine tools, construction machinery, textile machinery, printing machinery, mining machinery and other equipment, and to accurately measure and test the horizontal and vertical positions of the installation.

So, do you know the application of the level bubble in the verification of the center position of the car headlight beam?

Application of Level Bubble in Verification of Center Position of Automobile Headlamp Beam

The standard light source box-level bubble of the headlamp detector calibrator is adjusted to the center position. When the upper, lower, left, and right positions are set to 0, the emitted light beam directly enters the headlamp detector being measured. At the same time, the upper, lower, left, and right positions of the instrument are also set to 0, theoretically making its reading larger. At this time, the position of the machine lighting column overlaps with the actual lighting column position. When the center position of the lamp post coincides with the position of the machine lamp post, it is recommended to measure only the height from the center of the lamp box to the ground.

Due to the error generated by machining and the systematic error generated by the whole instrument debugging, the position of the mechanical light column is difficult to match the position of the actual light column, so the concept of how to determine the center position of the light column is put forward.

First, place the headlamp corrector to be checked in one position, and carefully adjust the three eccentric bolts on the base to ensure that when the headlamp corrector of the column is in the front, rear, left, and right positions, the level bubble is in the center position. Then move the left, right, upper and lower positions of the headlamp corrector until the light intensity reading is large, which is the center position of the light column, and the readings of the left, right, upper and lower positions are the deviation of the instrument itself. Then, the height value measured with the altimeter (or other measuring tool) is the height value of the actual center of the light column. This reading is different from the scale that often sits on a post. The scale on the post is the center height of the light to be measured during inspection.
