The working principle of an oil pressure buffer is to convert the kinetic energy of the elevator into heat energy through the damping effect of hydraulic oil, thus achieving buffering. The specific process is as follows:
When the elevator car or counterweight device hits the impact plate of the oil pressure buffer at a certain speed, the impact plate pushes the piston downward.
As the piston moves downward, the hydraulic oil in the cylinder flows through the throttle holes or gaps on the piston to the upper part of the piston or other parts of the cylinder. Since the size of the throttle holes or gaps is relatively small, it restricts the flow speed of the hydraulic oil, causing a large resistance, namely the damping force, during the flow of the hydraulic oil.
The kinetic energy of the elevator is consumed in the process of overcoming the damping force and is converted into the internal energy of the hydraulic oil, which raises the temperature of the hydraulic oil. In this way, the motion energy of the elevator is absorbed and dissipated, thus achieving the buffering effect.
After the impact force of the elevator disappears, the reset spring in the buffer will push the piston upward, allowing the hydraulic oil to flow back to the lower part of the cylinder, getting ready for the next buffering operation
