A choice between self-compensating and adjustable shock absorber

The industrial shock absorbers from HOILD top off the company's offerings in damping technology. This HOILD category gives designers a choice between self-compensating and adjustable shock absorber. Whichever design is chosen, this type of shock absorber impresses with its robustness and operational readiness wherever heavy loads need to be reliably stopped on-the-spot and at a precise point. 

Pneumatic shock absorber in various industries

Holid industrial shock absorbers are used in various industries, like factory automation, heavy industry, defense industry and health machines, to save costs, improve machine efficiency, increase machine operating life and reduce noise pollutions and maintenance costs. As a hydraulic shock absorber manufacturer, Holid manufactures adjustable and self-adjusting shock absorbers, hydraulic buffers (crane buffers), hydro checks and gas springs. 

Industrial Shock Absorbers suited for all loads

HOLID industrial shock absorbers work hard. Their application means moving loads are evenly decelerated over the full stroke. The result: the lowest braking force and shortest braking time. The series from HOLID is viewed as the reference standard for medium-sized damping technology. Many innovations such as diaphragm accumulators, long life seals, hardened inner pressure chambers and make a decisive contribution towards extension of the service life. This means that the effective load range can be increased considerably, providing users with more scope with respect to the absorber size and greater utilization of the machine's output. HOLID industrial shock absorber manufacturers offers a wide range of matching accessories for all absorber series. This eliminates internal production of assembly parts which involves high costs and loss of time.

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.

Industrial shock absorbers - Lightening maintaining time, extending using time.

Industrial shock absorbers is adopter special structruedesign. It converses the kinetic energy to heat energy, and then discharge the heat energy into the air. It is an idealproduct of both absorbing shock energt and making the optimum soft stop. oil filled shock absorbers plays a key part of ruducing machines' wearing away. Lightening maintaining time, extending using time.

The difference of gas shock absorber and hydraulic oil shock absorber

The difference is that a gas shock absorber is a hydraulic oil shock absorber which is injected a certain amount of low-pressure nitrogen gas, under the same design, the other physical characteristics of both shocks are almost the same ie have the same size, this means, diameter, length, also have the same piston, but will have valves with larger holes for comfort while smaller holes for driver control, this allows better control of rebound and compression. The low pressure nitrogen gas is used to avoid the problem of aeration, ie presence of bubbles in the operation of the unit, oil shock absorber during operation generates bubbles which passing through the holes in the piston ( where the process of damping ago) reduces its damping capacity, resulting in knocks and noise inside the industrial shock absorbers, the gas does is separate the oil and avoid air bubbles. This allows better performance, comfort and driving safety in the same unit, than a shock abosrber without gas.

The function of pneumatic shock absorber

In the automated machinery as hydraulic recoil buffer can reduce vibration and noise, moving objects generated by the kinetic energy into heat and the release in the atmosphere, the action will be effective in the balance of objects to stop; Industrial shock absorbers to increase efficiency of machinery to increase productivity, reduce the machine life extension Maintenance costs, the mechanical action to maintain the stability of product quality, the operation of the machine more secure to avoid accidents, so that the work environment to send to improve staff efficiency and increase their competitive edge.

Shock Damper

Self-compensating industrial shock absorbers are highly engineered, fixed, multi-orifice units that decelerate moving weights smoothly regardless of changing conditions, and require no adjustment. These versatile performers offer wide effective weight ranges for handling a wider range of applications and increased velocities.  As a moving load impacts the shock absorber the piston travels through the stroke and forces hydraulic oil shock damper fluid through the multi-orifice inner tube.

Industrial shock absorbers are maintenance-free, ready to install hydraulic components. These shock absorbers are specially designed as accessories for our linear modules, lifting units, rotary modules and intermediate positions.Heavy duty shock absorber has a soft shock absorbing effect because the self-pressure-regulation function.

The adjustable miniature shock absorber for industrial

These adjustable miniature shock absorbers from Holid can be used to precisely meet the customer's application needs and are therefore industrial shock absorbers found everywhere in industrial, automation and machine engineering and many other applications.
