Bubble level manufacturers believe that many people are not familiar with the level, because non-staff do not often contact the level. The level is a common measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the machine tool guide rail, the horizontal and vertical position of the equipment installation, etc.

What are the characteristics of bubble level?

Bubble level manufacturers believe that many people are not familiar with the level, because non-staff do not often contact the level. The level is a common measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the machine tool guide rail, the horizontal and vertical position of the equipment installation, etc.

Bubble level manufacturers believe that the level tube of the level is made of glass. The inner wall of the horizontal pipe is a curved surface with a certain radius of curvature, and the pipe is filled with liquid. When the working principle of the level is tilted, the bubbles in the level tube will move to the rising end of the level, thereby determining the position of the level. The larger the radius of curvature of the inner wall of the level tube, the higher the resolution, and the smaller the radius of curvature, the lower the resolution. Therefore, the radius of curvature of the level tube determines the accuracy of the level.

The level is a measuring tool with strict packaging requirements. Each level should be packed in shockproof boxes made of foam materials, coated with anti-rust oil, and packed in plastic bags before packing. The shockproof case shall be placed in a strong carton or wooden case, and the outside of the case shall be painted with the specified marks. The level should be stored in a dry, ventilated, non-corrosive gas warehouse. Avoid falling and rain during handling.

Bubble level manufacturers believe that the level is an angle measuring instrument that measures the tilt angle away from the horizontal plane. The key component of the level 3354 that the inner surface of the main bubble tube has been polished, the outer surface of the bubble tube is engraved with scales, and the inside is filled with liquid and bubbles. The main bubble tube is equipped with a bubble chamber to adjust the length of the bubble. The bubbles are always level with the bottom surface, but may change during use. For this purpose, an adjusting screw is provided.

1. Before measurement, the measurement surface should be carefully cleaned and dried, and the measurement surface should be checked for scratches, rust, burrs and other defects.

2. Check whether the zero position is correct. If not, the adjustable level should be adjusted. The adjustment method is as follows: put the level on the plate and read the scale of the bubble tube. At this time, rotate the level about 180 at the same position of the plate, and then read the scale of the bubble tube. If the readings are the same, the bottom of the level is parallel to the bubble tube; if the readings are inconsistent, use a spare adjusting needle to insert the adjusting hole and adjust up and down.

3. In the measurement process, the influence of temperature should be avoided as much as possible. The liquid in the level has a great influence on the temperature change. Therefore, attention should be paid to the influence of hand heat, direct sunlight, breathing and other factors on the level.

4. When using, the reading should be taken in a vertical and horizontal position to reduce the influence of parallax on the measurement results.

Bubble level manufacturers believe that the level is mainly used to detect the straightness of various machine tools and other types of equipment guide rails, as well as the horizontal and vertical positions of equipment installation. It can also be used to measure small angles and working surfaces with V-grooves, and can also measure the installation parallelism of cylindrical workpieces, as well as the horizontal and vertical positions of the installation. It is an indispensable precision measuring tool for installing and measuring the levelness and verticality of mechanical equipment.
