Is the highest or lowest pneumatic chair the safest?

The air pressure is mainly controlled by the air cylinder on the chair, which is mainly composed of upper and lower end covers, piston rod, piston and air cylinder. When making a chair, fill the cylinder with gas.

Theoretically, cylinders should be filled with inert gas, such as nitrogen. When a person sits on a chair, the piston will be pressed by the piston rod, and then the piston will exert pressure on the gas in the cylinder. When the gas is compressed by pressure, the height of the chair will drop, and vice versa.

When the air pressure drops to a minimum, it is high because the rise is automatic, that is, the internal air pressure is pushed up. When the cylinder rises to the highest, the volume of the cylinder is the largest, and the internal gas quality is certain and sealed. The larger the cylinder volume, the lower the pressure, so the lowest air pressure is the smallest.

When the chair rises, the gas is at the top, and the pressure exerted on the human body compresses the air, which is very dangerous, while the weight of the lowermost human body does not compress the air, which is the safest. Reduce the safest

So how to use it safely: 1, choose the products of regular manufacturers. Buy products with qualified marks, and don't covet cheap and inferior goods. 2. To buy a swivel chair, first check whether the plastic bottom plate of the swivel chair is firm, and then slide the swivel chair back and forth. A swivel chair with good quality is more flexible and will not tilt.

Don't rotate and lift the chair repeatedly when it is in use. After use for a period of time, it should be checked in time. Once cracks and signs of looseness are found, they should be repaired and replaced in time.
