How the chair lift works
1, the lifting of the chair is mainly achieved by the lifting device under the chair surface, the current lifting device is mainly divided into three categories: oil pressure, mechanical and air pressure. Air lift chair is the most common chair lift, air lift chair has a pressure bar.
2, the pressure rod is a gas and liquid as the working medium, can support, buffer, braking, height adjustment and Angle adjustment functions of the elastic element, the basic principle is the internal filled with high pressure nitrogen, because the piston is provided with a through hole.
3, the gas pressure at both ends of the piston is equal, and the cross-sectional area on both sides of the piston is different, one end is connected with the piston rod and the other end is not, under the action of gas pressure, the pressure to the side of the small cross-sectional area is generated, that is, the elasticity of the pressure bar, the person sits up to the lifting shaft pressure.
4, the lifting shaft gently drops, the speed is uniform, can be reduced to the lowest point. Do not give the lifting shaft external force, lifting shaft rises back to the highest point. Regular manufacturers are filled with nitrogen, the concentration is generally above 99%, and the pressure is about one or two atmospheres.
The hydraulic lifting chair is able to raise or lower the principle of pressure, the principle is very simple, and the hydraulic lifting chair is not dangerous. However, you should pay attention to the load-bearing force of a hydraulic lifting chair has a certain range of conditions, if it exceeds this range, the chair may be crushed, so pay attention to not many people sit on a hydraulic lifting chair at the same time, or place heavy objects on it, so as to avoid damage to the chair, it is not worth the loss.
