The compression spring is adapted to those places?

Spring buffer in the impact, it makes the kinetic and potential energy of the car or the weight into the elastic deformation energy of the spring, due to the reaction force of the spring, make the car or the weight deceleration. When the spring is compressed to the limit position, the spring to release the elastic deformation energy in the buffer process, the car is still to rebound up to produce impact. The higher the impact speed, the higher the rebound speed.　Spring buffer generally consists of buffer rubber, buffer seat, spring, spring seat, set up two or three side by side in the pit, and one is commonly used under the counterweight. In order to adapt to the large tonnage car, the compression spring by the combination of spring stacked together. In order to enhance the stability of the spring, the spring buffer with a large stroke height is equipped with a guide sleeve under the spring or a guide bar in the spring, or the spring seat height can be increased under the premise of meeting the stroke to shorten the ineffective stroke.　Pressure snubber in the stopping period of the force is approximately constant, so that the plunger approximate uniform deceleration movement.　Hydraulic buffer is the use of liquid flow damping, to ease the impact of the car or the counterweight, has a good cushioning performance. In the same conditions of use, hydraulic buffer stroke required than the spring buffer is reduced by half.　Various hydraulic buffer structure is different, but the basic principle is the same. When the car or counterweight impact buffer, plunger downward movement, compression of the oil cylinder oil, so that the oil through the throttle hole outflow, in the system to stop the car or counterweight process, its kinetic energy into the thermal energy of the oil, that is, the consumption of the elevator's kinetic energy, so that the elevator to a certain rate of deceleration gradually stop down. When the car or counterweight leaves the buffer, the plunger resets upward under the action of reset spring.
