An Elevator Hydraulic Buffer is a safety device installed in elevator systems that absorbs hydraulic pressure surges that may be caused by sudden stopping or starting of the elevator car during operation. It is typically installed in the elevator pit, beneath the elevator car, and consists of a piston, cylinder, and hydraulic oil. When the elevator car experiences sudden acceleration or deceleration, the hydraulic buffer will compress or expand, absorbing the excess energy in the hydraulic system and slowing down the movement of the elevator car. The hydraulic buffer is designed to operate automatically, without the need for human intervention, to ensure the passengers' safety in the event of an emergency. It is an essential component of elevator systems, providing a reliable and efficient way to control the elevator's speed and protect passengers' safety.
Although the structures of various elevator hydraulic buffers are different, the basic principles are the same. When the car or counterweight hits the buffer, the plunger moves downward, compressing the oil in the cylinder, causing the oil to overflow through the throttle hole. In the process of stopping the car or counterweight, its kinetic energy is converted into heat energy of the oil, which consumes the kinetic energy of the elevator and makes the elevator gradually stop at a certain deceleration. When the car or counterweight leaves the elevator car buffer, the plunger resets upward under the action of the reset spring.
Elevator Hydraulic Buffer is a reliable and efficient safety device that can absorb excess hydraulic pressure surges caused by sudden acceleration or deceleration of the elevator. It can effectively slow down the movement of the elevator, thereby protecting passengers' safety in the event of an emergency.
The hydraulic buffer is designed to operate automatically, without the need for manual intervention, which ensures a high level of safety. It can sense excessive hydraulic pressure and immediately take action to absorb the excessive energy, making it a reliable safety device for elevator systems.
Elevator Hydraulic Buffer can extend the lifespan of the elevator system components by reducing shock and vibration that may occur during operation. This can significantly reduce wear and tear, which can ultimately lead to lower maintenance costs and longer service life of the elevator system.
