How to adjust the height of a computer chair, this problem bothers many people. PHP editor Xigua will introduce the steps to adjust the height of your computer chair to help you find a comfortable and ergonomic height. With the details below, you'll learn how to properly adjust your computer chair height to improve your posture and overall health.
The lifting and lowering of computer chairs is mainly achieved through pneumatic or hydraulic lifting devices. The working principles of these two devices are roughly the same, and they control the lifting and lowering of the chair surface by changing air pressure or hydraulic pressure.
For pneumatic lift chairs, there is a cylinder under the seat surface, and the piston pneumatic rod in the cylinder moves up and down to control the lifting of the chair. When you sit in a chair and lift up a lever underneath the chair, you use your body weight to lower the chair. On the contrary, the chair rises.
As for the hydraulic lift chair, the lifting principle is similar, but the medium used is different. The hydraulic lift chair uses liquid instead of gas.
In the process of using the computer chair, it should be noted that the pneumatic lift chair is a new type of chair. There is a cylinder inside the lift chair, and the piston rod in the cylinder moves up and down to control the lifting of the swivel chair. The pneumatic rod is filled with nitrogen. Generally, the gas purity is lower than 90%, which may cause safety hazards. If the pneumatic rod is not tightly sealed, it can easily cause gas to burst out. In addition, the material of the pneumatic rod itself is also critical. If unqualified materials are used, it may Cause an explosion. Therefore, when buying a lifting office chair, you need to buy genuine products and not be greedy for money and cause unnecessary harm to the body. Furthermore, when using a lifting office chair, you need to sit down and get up gently and do not exert too much force on the seat during other actions. .
In addition, if you find that the computer chair cannot be raised or lowered, there may be a problem with the air pressure rod. At this time, you may need to replace the air pressure rod. The replacement method includes: turning the computer lift chair upside down, and using a hammer to remove the base of the chair first, preferably a rubber hammer. A metal hammer can easily knock off the paint and leave small pits. Just take a hammer and hit it hard along the steel ring at the bottom, and then break it off. Then there is the hydraulic ejector and the upper seat, which also uses a hammer. Use a screwdriver to remove the upper seat before knocking to facilitate subsequent work. Similarly, use a hammer to hit the metal floor hard, hold the hydraulic ejector in one hand, and step on it with your feet to remove it, and then replace it with a new one.
