Structural foundation The pressure bar is mainly composed of cylinder, piston, piston rod, sealing ring and filled gas. The cylinder is a sealed chamber filled with a certain amount of inert gas (such as nitrogen), the piston separates the cylinder into two chambers, one end of the piston rod is ...Read more »

steel High quality carbon steel: This is one of the most commonly used materials for pressure rods. High quality carbon steel has good strength, toughness and corrosion resistance, and can withstand greater pressure without deformation or rupture. Through precise processing technology, it can be ...Read more »

Visual inspection Check the surface of the pressure rod: carefully observe whether the surface of the pressure rod is smooth, and there are no obvious scratches, dents, cracks or rust. Scratches and dents may weaken the structural strength of the pressure rod, cracks may directly lead to gas leak...Read more »

Pressure rod quality problem Material defects: If the pipe wall of the pressure bar uses inferior steel, the thickness is insufficient or the material is not uniform, the pressure resistance will not meet the standard requirements. In the normal pressure change or use process, it is easy to ruptu...Read more »

Normal pressure bar and high quality pressure bar Ordinary pressure bar: Ordinary pressure rods usually use relatively basic materials and relatively simple manufacturing processes. The wall of the tube may be thin, generally about 1-2 mm, and the quality of the steel used is relatively ordinary....Read more »

Visual inspection View surface integrity Look carefully at the wall surface of the pressure rod. A normal pressure rod surface should be smooth, with no obvious dents, scratches, cracks, or signs of corrosion. If the surface is found to be damaged, it may affect the strength and tightness of the ...Read more »

Factors affecting the service life of the barometric bar Frequency and intensity of use: If the office chair is frequently raised and lowered every day, such as in an office environment, many people share a chair, or the user needs to adjust the height of the chair frequently to adapt to differen...Read more »

Consumer factor Health and comfort needs: With the improvement of people’s health awareness, the requirements for the comfort and ergonomic design of office chairs are increasing.

Perforating wound When the barometric bar of an office chair explodes, fragments of the barometric bar may splash out at high speed. These fragments are usually sharp pieces of metal with a strong penetrating force. If the debris hits the human body, it can cause puncture wounds, such as in the l...Read more »

Pressure rod quality problem Poor material: air pressure bar is a key part of the office chair, some bad manufacturers in order to reduce costs, the use of poor quality steel or other metal materials to make air pressure bar. These inferior materials may not be able to withstand normal pres...Read more »

Intelligence and technology application Automation and convenience functions: office furniture will be equipped with more automation devices, such as intelligent lifting desk can automatically adjust the height through the button or preset program to adapt to different working posture and needs, ...Read more »
