Shock absorber is a consumable vehicle in the process of the use of vulnerable parts, shock absorber work is good or bad, will directly affect the smooth operation of the excavator transport truck and other parts of the life, so we should make the shock absorber often Good working condition. The following methods can be used to check the work of the shock absorber is good.
1. So that excavator transport truck in the poor road conditions on the road after 10km parking, hand touch shock absorber shell, if not hot, indicating no resistance inside the shock absorber, shock absorber does not work. At this point, you can add the appropriate lubricants, and then test, if the shell heat, excavator transport truck shock absorber internal lack of oil, should add enough oil; otherwise, that shock absorber failure.
2. Forced to press the bumper, and then release, if the digging machine truck has 2 to 3 jump, then the excavator transport truck shock absorber work well.
3. When the excavator transport truck slow driving and emergency braking, if the digging machine truck vibration is more intense, indicating that digging machine truck shock absorber problems.
4. Remove the excavator transport truck shock absorber to its upright, and the lower end of the connection ring clamp on the vise, forced to pull the vibration pole several times, this time there should be a stable resistance, pull up (recovery) resistance should Greater than the resistance when the pressure down, such as resistance is unstable or no resistance, may be digging machine truck shock absorber internal oil or valve parts damaged, should be repaired or replaced parts.
In determining the excavator truck shock absorber problems or failure, you should first check the shock absorber is leaking or traces of old oil spills.
Oil seal gasket, sealing gasket rupture damage, storage tank nut nut loose.
If you find the oil spill, first tighten the cylinder nut, if the shock absorber is still oil, it may be oil seal, sealing gasket damage failure, should replace the new seal. If still can not eliminate the oil spill, should pull out the damping rod, if you feel the card or the severity of the moment, and then further check the gap between the piston and the cylinder is too large, digging machine truck shock absorber piston link with or without bending , Piston rod surface and cylinder whether there is scratches or pull marks.
If there is no oil spill in the excavator transport truck, it should check whether there is any damage, de-soldering, rupture or falling off of the damping truck connecting pin, connecting rod, connecting hole and rubber bushing. If the above check is normal, it should be further decomposition of the shock absorber, check the piston and cylinder between the mating gap is too large, whether the cylinder cylinder injury, valve seal is good, valve and valve seat fit, Whether the expansion of the spring is too soft or broken, according to the situation to take grinding or replacement of the way to repair.
