Principle of pneumatic chair
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. Manufacturers will fill a certain amount of gas into the cylinder when making chairs. Theoretically, cylinders should be filled with inert gas, such as nitrogen. When the human body sits on the chair, the piston will exert a certain pressure through 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. Its load test and impact test are both 200 kg.

Finally, when we consumers buy pneumatic chairs, we should first look at the balance of the four wheels and see whether all the wheels can rotate flexibly and tilt when they rotate. The second is to see whether the bearing capacity and quality of wheels and brackets are firm; Third, it depends on whether the plastic floor of the chair is strong. Try to buy a lift chair with a cylinder far from the bottom of the chair surface and a tight package. If a protective steel plate is installed between the bottom of the chair surface and the pneumatic rod, the safety will be better. Carefully check the material, process and other details of the pneumatic rod. If these parts are defective, do not buy them. At the same time, procedures such as shopping invoices are kept for future rights protection. Finally, we should pay attention to the correct use of lifting chairs. Don't let the chair near something too hot, such as an oven or oven; Avoid violent impact and do not rotate or lift frequently. Due to the limited service life of the pneumatic rod, it should be checked frequently, and repaired or replaced in time if it is found to be damaged or seriously worn.
The above is the principle of pneumatic chair and the price content of pneumatic chair, hoping to bring you help.
