How does hydraulic shock absorber work?

Blanking requires the press to build tonnage that exceeds the shear strength of the material. When this happens, the press frame and housings are loaded in tension. At the moment of material fracture, the resisting forces in the press are released and the press slide is allowed to accelerate downward at speeds that approach 10g's.Sides and adjusted properly, the hydraulic shock absorber will automatically develop a resisting counter pressure force (through internal hydraulic pressure control) that will absorb the acceleration and eliminate the resulting shock and vibration.

Miniature shock absorbers provide a positive stop

The series are miniature shock absorbers. They are specially designed with multiple orifices to smoothly stop moving loads. This hydraulic shock absorber uses the bumper head type to provide a positive stop to prevent damage caused by the piston “bottoming out” in stage of stroke without stop collar. 

Introduction to Shock Absorber

A shock absorber or (oil shock damper) is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. A shock absorber is a type of dashpot.Pneumatic and hydraulic shock absorber is used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below).One design consideration, when designing or choosing a industrial shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be stored and used later. In general terms, shock absorbers help cushion vehicles on uneven roads.

Hydraulic shock absorber to car

The hydraulic shock absorber mostly comprises of a cylinder filled with hydraulic oil and a piston, which moves with every vertical movement of the wheel. This piston glides up and down when the spring is compressed and extended during the journey. During compression (pressure stage), the oil beneath the piston must flow through a narrow valve opening. This Oil Hydraulic Damper process generates friction that converts the kinetic energy from the oil into heat, brakes the movement of the piston and therefore damps the vibration in the car body. The compressed oil flows to a reserve pipe via valves in the base. The damping resistance varies depending on the speed at which the piston is moving, the volume of oil and the number and size of valves. In general, the faster the piston rod moves, the higher the force acting on the piston and more resistance is created. When the spring is extended (pull phase), the oil flows through an even narrower valve back down through the piston, achieving a stronger damping that when the spring is compressed. This is required so that the spring can relax in a controlled way and so that the wheels do not lose contact with the ground.

The pneumatic shock absorber has larger energy absorption capacity

The industrial shock absorber is adjustable type so you could control the damping force according to impact velocity.The new shock absorber has larger energy absorption capacity compared with that of old model because of increasing total surface area of Piston.So it has wide range of Effective Weight.The body of hydraulic shock absorber is designed as one unit so it is very solid and root up the"Bottom out "problem.Threaded body of shock absorber provide mounting flexibility, location accuracy and increased surface area for improved thermal energy dissipation to the atmosphere.Material of piston rod is hardened stainless steel and the bearing protect the seal and is made of special material that remains durable for a long time to ensure a long lifespan.

Function and principle elevator hydraulic buffer

The hydraulic shock absorber is an energy buffer type, its working principle is: When the hydraulic shock absorber of the car and by the impact of heavy plunger

Downward movement of the compression cylinder oil, oil sprayed into the piston chamber through an annular orifice. When the oil through an annular orifice, since the cross-sectional flow

Sudden decrease in the area, will form a vortex, so that the liquid inside the particle hit each other pull, friction, kinetic energy is converted into heat dissipated, thereby

Consume the kinetic energy of the elevator, the car or the counterweight gradually slow to a halt. The use of hydraulic shock absorber damping effect of the liquid flow of buffer

The impact of the car or counterweight, when leaving the car or the counterweight buffer plunger return spring action, up reset, the oil flow again

Back to the fuel tank, a return to normalcy. Since the hydraulic shock absorber is a way to implement the energy consumption of the buffer, so no rebound effect.

Meanwhile, the variable rod effect, the plunger pressure ,, lower annular orifice cross-sectional area gradually becomes smaller, make the kind of electrical impulse through contact

Nearly uniform deceleration. Accordingly, the industrial shock absorber having a stable buffer advantages, in the case where the same conditions, the oil level is red

It can reduce the need to travel more than half of the buffer spring. Therefore, the hydraulic shock absorber for a variety of speed elevators.
