Why does the chair lift explode how to prevent the chair from exploding?

The occasional escalator explosion caused consumers to panic. Then why did the chair lift explode? How to prevent the chair from exploding? Furniture fans explain it for you.

The reason for the explosion of the chair lift

At present, the lifting devices used in the chair lifts on the market are classified into three categories: oil pressure, mechanical type and air pressure. In the low-end chair lift, the pressure is mostly. The pneumatic lift chair has a cylinder. The piston pneumatic rod in the cylinder moves up and down to support the chair lift. The regular manufacturers use nitrogen to fill, the concentration is generally above 99%, and the pressure is about one or two atmospheres.

This kind of formal chair lift generally has three situations that may explode.

First, the purity of nitrogen is insufficient. In the case of high temperature environment or excessive friction, the temperature of the cylinder will rise sharply, the pressure will increase, and explosion may occur. Second, the wall of the cylinder container is not strong enough or the material is poor, and explosion may occur. The seal is not tightly sealed, causing gas to escape. Some black manufacturers are more likely to cause an explosion because they are low-cost, filled with even high-pressure air.

Furniture fans remind: do four points to avoid the chair lift

The industry insider said that although the explosion is a small probability event, the possibility still exists, which requires consumers to be vigilant and do the following four things:

1. Be sure to purchase the chair lifts produced by regular manufacturers. Do not buy cheap goods in a cheap way;

2. When the chair is in use, do not lift it repeatedly;

3. If you are not a professional, do not disassemble the cylinder, and do not let the chair be close to something too hot, such as a stove or oven;

4. After using for a period of time, the professional should be inspected in time. Once the cracks and loose signs are found, they should be repaired and replaced in time.

The chair lift, especially the air lift chair, may explode, but as long as we purchase a chairlift that is factory-supplied, quality and reliable, and there is no frequent lifting when I use it, I will find the problem in time. Maintenance, the chances of a chair lift will be much smaller. Of course, if you don't want the chair to explode, the best way is to change the chair and take the wooden bench.
