缓冲器有什么作用What is the function of buffer

　　电梯缓冲器的作用

Function of elevator buffer

　　缓冲器安装在井道底坑内，要求其安装牢固可靠，承载冲击能力强，缓冲器应与地面垂直并正对轿厢（或对重）下侧的缓冲板。缓冲器是一种吸收、消耗运动轿厢或对重的能量，使其减速停止，并对其提供***一道安全保护的电梯安全装置。

The buffer shall be installed in the pit of the shaft, which shall be installed firmly and REliably with strong impact bearing capacity. The buffer shall be vertical to the ground and fACE the buffer plate at the lower side of the car (or counterweight). Buffer is a kind of elevator safety device that absorbs and consumes the energy of the moving car or counterweight, makes it slow down and stops, and provides the last safety protection for it.

　　电梯在运行中，由于安全钳失效、曳引轮槽摩擦力不足、抱闸制动力不足、曳引机出现机械故障、控制系统失灵等原因，轿厢（或对重）超越终端层站底层，并以较高的速度撞向缓冲器，由缓冲器起到缓冲作用，以避免电梯轿厢（或对重）直接撞底或冲顶，保护乘客或运送货物及电梯设备的安全。

During the operation of the elevator, due to the failure of the safety gear, the insufficient friction of the traction wheel groove, the insufficient braking force of the holding brake, the mechanical failure of the traction machine, and the control system failure, the car (or counterweight) exceeds the bottom floor of the terminal floor and collides with the buffer at a higher speed, so as to prevent the elevator car (or counterweight) from directly hitting the bottom or top, and protecting the passengers Safety of passenger or goods and elevator equipment.

　　当轿厢或对重失控竖直下落，具有相当大的动能，为尽可能减少和避免损失，就必须吸收和消耗轿厢（或对重）的能量，使其安全、减速平稳地停止在底坑。所以缓冲器的原理就是使轿厢（对重）的动能、势能转化为一种无害或安全的能量形式。采用缓冲器将使运动着的轿厢或对重在一定的缓冲行程或时间内逐渐减速停止。

When the car or counterweight is out of control and falls vertically, it has considerable kinetic energy. In order to reduce and avoid the loss as much as possible, it is necessary to absorb and consume the energy of the car (or counterweight) to make it stop in the pit safely and smoothly. Therefore, the principle of buffer is to convert the kinetic energy and potential energy of the car (counterweight) into a harmless or safe energy form. The use of buffer will make the moving car or counterweight gradually slow down and stop in a certain buffer stroke or time.

　　汽车缓冲器的作用

The function of automobile buffer

　　汽车缓冲器是通过利用液压弹簧减震功能，当汽车瞬间相撞时，缓冲器就起到了缓冲作用从而减轻两车相撞后的破坏程度，提高车与人的安全性。一般来说，对于新车，减震缓冲器起到的是使驾驶更加舒适的作用；而当减震弹簧用久之后，往往因缺乏弹性而出现疲软现象，反应不灵敏，很容易引发事故。

The vehicle bumper is through the use of hydraulic spring damping function, when the car collides instantaneously, the buffer plays a buffer role, so as to reduce the damage of two vehicles after collision, and improve the safety of vehicles and people. Generally speaking, for a new car, the shock absorber plays a role of making driving more comfortable; and when the shock absorber spring is used for a long time, it is often weak due to lack of elasticity, and the response is not sensitive, which is easy to cause accidents.
