I don't know if you 've ever heard of a pneumatic lift chair? I'm sure you all know that you 've even sat on a lift chair. Let's deepen our understanding of the air lift chair. Only by correctly understanding the lift chair can we use the lift chair correctly and avoid the danger caused by the wrong use of the lift chair.
air pressure lift chair why would explode:
Pneumatic chair (pneumatic pressure chair) common lift chair, because of its design of human nature is widely used in life, office, service industry. The main control of air pressure rise and fall is the cylinder on the chair. The cylinder is mainly composed of upper and lower end covers, piston rod, piston and cylinder. The manufacturer fills the cylinder with a certain amount of gas when making the chair. In theory, the cylinder should be filled with inert gases such as ammonia. When the human body sits on the chair, a certain pressure is given to the piston through the piston rod, and the piston then generates pressure on the gas in the cylinder. The gas is compressed by pressure, and the height of the chair will drop, but the opposite will rise. Its load test and impact test are 200kg. That is to say, the lift chair can withstand the pressure of most people.
Because the lift chair itself has many advantages, it is still very popular in life, but there are also certain safety hazards. First of all, let's learn about the classification of the lift chair. Generally speaking, the lift chair atmosphere is pneumatic, hydraulic and mechanical. At present, the pneumatic lift chair occupies a high share in the market. Its working principle is mainly to use the pressure difference to realize the movement of the piston rod, so as to achieve the effect of adjusting the height of the seat. When the hydraulic lift chair is used, it needs to use the driving force applied from the outside to realize the lifting function of the chair. Compared with the pneumatic lift chair, the production cost is low, but the safety is not as good as the mechanical lift chair, so the lift chair explosion accident also occurs. From the pneumatic lift chair. Therefore, it is recommended that you choose mechanical lift chair when buying lift chair.
You 've probably heard the news about the chair lift explosion. When it comes to the explosion probability of the lift chair and the cause of the possible explosion, many friends don't know much. There are two kinds of situations that lead to the explosion. The first is the uneven thickness of the gas spring wall or the excessive pre-pressure. The second kind may be the explosion caused by frequent height adjustment and rotation of the lift chair, causing it to overheat. When we use the lift chair, although the ammonia gas is squeezed to increase the pressure, it is still within the limit of an air pressure expansion, so there will be no explosion. However, the current lift chair uses some inferior pneumatic rods, which often have problems such as insufficient nitrogen purity. Therefore, especially in the summer high temperature, frequent adjustment of the lifting height may cause an explosion. Therefore, in general, the explosion probability of the lift chair depends on whether the material and quality of the lift chair are qualified.
