What are the reasons the chair lift is so hard to get down

Chairlifts are not uncommon in everyday life. So the question is, what are some of the reasons chair lifts are so hard to get down? How does the chair lift work? Let's learn more about it.

What are the reasons the chair lift is so hard to get down

Because it was the air rod of the chairlift that had a problem. A closed cylinder in which the piston extends to the outside piston rod. The air pressure in the cylinder is greater than that outside, and there are small holes on both sides of the piston in the cylinder. According to relevant knowledge, if the piston rod is pressed inward, the resistance is stable and constant, that is, the difference between the air pressure at both ends of the piston rod.

The self-locking type is a freestyle piston rod with a shaft. The inner end of the shaft is connected to a valve, which operates the connecting hole of the piston part. The valve is pressed in the process of connecting the hole, similar to a freestyle. And the valve spring in the process of the connecting hole disappeared, will lock.

How does the chair lift work

The reason why the lift chair can have the function of lifting, the key is the pressure pole at the bottom of the seat, because it is filled with high pressure gas, used to adjust the pressure, and finally meet the role of adjustment up and down, of course, is able to fix the height, which mainly depends on the sealing performance of the gas.

Because the upper and lower parts of the gas rod are rubber sealing rings to achieve the sealing effect, when the use of time is too long wear, aging and other conditions, resulting in poor air tightness performance, then the internal pressure can not support the weight of the human body, that is, the automatic decline will occur, the serious problem is likely to lead to the computer chair can not rise.

Of course, in this need to remind you that: we just started to adjust the chair lift, do not always adjust the chair lift, because often adjust easily lead to the damage of the pressure rod.
