Advantages of Adjustable hydraulic damper

Adjustable hydraulic damper are durable and feature single or double acting-designs. The travel speed can be easily adjusted and remains constant throughout the stroke. The single acting version of oil shock damper is controllable in one direction only, with free flow in the opposite direction. Adjustment is easily achieved by pulling out fully and turning the rod until the desired damping speed is attained. A built-in antilock guard allows adjustments to be made at any damping rate without unit lock up.

Pneumatic shock absorber provide linear deceleration

Industrial shock absorbers convert the kinetic energy of a load into heat which is dissipated into the atmosphere. They stop a moving load with no rebound and without transmitting potentially damaging shocks to equipment. In its most general form, a shock absorber consists of
• a double-walled cylinder with space between the concentric inner and outer walls,
• a piston,
• some means of mechanical return for the piston, and
• a mounting plate. The piston usually is returned to its initial position by a spring, which can be mounted externally around the piston rod or internally on the inside of the cylinder body.
A series of orifices is drilled in the inner cylinder wall at exponential intervals. The reason for the exponential spacing is derived from the equation for kinetic energy: KE= ½ mv2. The cylinder is filled with fluid, and all air is bled from the fluid because air bubbles cut the efficiency of the shock absorbers by causing spongy or erratic action.
When a moving load contacts the piston rod, it moves the piston inward, forcing fluid through the orifices in the inner cylinder wall. The fluid is forced through the oil return passages, into the space be hind the piston head. As the piston retracts, it closes the orifices behind it, reducing the effective metering area, and maintaining a uniform deceleration force as the load loses its energy.
Fluid pressure is constant in a double acting shock absorber , providing constant resistance to the load. The load slows to a stop as its kinetic energy approaches zero. No rebound occurs because the shock absorber stores no energy. Several events must happen for the piston to return to its extended position. First, the load must be removed. The spring then pushes the piston outward, opening a check valve, which lets fluid flow from behind the piston to the space the piston was in its retracted position. Smaller shock absorbers, (bores less than 3 in.) have a ball check valve to control fluid flow. Larger models use a piston-ring check valve.
