damping buffer is also called hydraulic buffer. Knight relies on hydraulic damping to buffer and decelerate the objects acting on the equipment, thus making the objects stop to play a certain degree of protection. At present, damping buffer is widely used in elevator lifting transportation, port machinery, vehicles and other mechanical equipment. With the existence of damping buffer, it can be used in the working process of the equipment, prevent damage to equipment due to hard collisions and play a safe buffer role.
Damping buffer It is an energy-consuming buffer that can be used in high-speed elevators. The damping buffer can also be divided into two types, one is a damping buffer with an orifice on the inner wall of the cylinder, And the other is a damping buffer with a tapered column and an annular hole. In the former, when the bottom of the car collides and touches the rubber buffer contact at the top of the damping buffer piston, the contact will absorb the impact like a spring. When the bridge compartment descends further, the piston will enter the oil filled with oil. Inside the oil cylinder, the oil inside the oil cylinder will enter the external oil storage tank from the throttle hole.
With the further descent of the piston, the throttle hole in the oil cylinder will gradually decrease and shrink, so that the area of the energy-saving hole is reduced and the oil retention capacity is increased. Therefore, sufficient pressure can be generated from it to force the car to move. Minimization occurs to make the car stable until it stops. When the car is lifted up at this time, the damping buffer will be reset just after the piston is loaded, and the oil will pass through the orifice and return to the oil cylinder from the oil storage tank. The damping buffer will automatically reset and be used again in the next time.
Hydraulic buffer with tapered column and annular hole. When the car descends and collides with the buffer, the plunger is pressed down into the oil cylinder, and the oil flows into the inner cavity of the hollow plunger through the annular hole, and the flow is controlled by the tapered column. When the plunger moves down, the opening of the annular hole gradually decreases, resulting in a constant braking force. When the car is lifted outward, a spring located within the plunger returns the plunger to its operative state. The hydraulic cylinder of
damping buffer is connected with the gun body. During the shooting process, the gun body drives the hydraulic cylinder to sit back together. The piston rod of the damping buffer is connected with the shoulder rest and abuts against the shoulder of the shooter. The cavity formed by the piston rod and the hydraulic cylinder is filled with hydraulic oil. After firing, the gun body sits back under the action of the resultant force of the gun bore, the shoulder rest can be considered fixed, the hydraulic cylinder moves backward relative to the piston rod, the cavity volume decreases, and the liquid pressure rises, forcing the hydraulic oil to pass between the hydraulic cylinder and the piston The annular leakage port flows into another cavity, and the buffer spring of the damping buffer is compressed to store the recovery energy.
