  COMPARISON OF SHOCK ABSORBING OF DASH POTS, PU RUBBERS, SPRINGS AND CEC SHOCK ABSORBERS

FORCE-STROKE TESTNG MACHINE

When shock absorber was affected by the force from outside, the main function of this testing machine is testing the relative curve between the pressure of inner tube undertake and the stroke of the shock absorber. That means through this curve, we can judge the efficiency of the shock absorber absorb the kinetic energy by the force it was affected.
 
 

The springs and polyurethane rubbers are widespread to use in earlier period, but due to provide non-linear deceleration and to result in strong resistance, all the kinetic energy of moving objects is not absorption and produce counter pressure, this is in low efficiency. If linear deceleration is necessary for a moving object, CEC Shock Absorbers is your best choice.


Examples of using CEC shock absorbers



 
  OPERATING PRINCIPAL OF SHOCK ABSORBERS  ▲Top

CEC Shock Absorbers’ main structure to combine with body, rod, bearing, inner tube, piston, fluid, spring. On impact the piston rod moves into the shock absorbers and the hydraulic fluid is pushed into the accumulator to produce resistant force, the pressure in the inner tube remains constant throughout the entire impact stroke. CEC Shock Absorbers providing a linear decelerationand brings the impacting object to stop smoothly and quietly. At the end of the impact stroke, the return spring pushes the piston to the original position for next cycle.

  selecION OF HYRAULIC SHOCK ABSORBERS  ▲Top
 
▲Three major factors to be considered:
1. How much energy to be dissipated each stroke?
2. How much energy to be dissipated per hour?
3. How much is your effective weight of your application?
After the three factors are calculated, go to the quick list to find the suitable shock absorbers.

Note:
1. Shock absorbers series allow approximate 1 mm fixed stop before the end of the stroke, not to be driven into the final position under full load.
2. Reuse is prohibited after disassembling; paint on the rod and threaded body is not allowed.
3. Stop collar protects shock absorber’s piston from bottoming out, Stop collar can be used in adjust the distance in stroke. Be sure the fixed board of the shock absorbers is strong enough.
4. To assembling, the off-center angle do not exceed 2°.
