6.3.5. Gas springs

 

If the pressure of the gas spring drops excessively, overheating and overheating could occur to the motor. In addition, any damage to the surface of the piston rod of the gas spring can cause a drop in pressure. Please manage to prevent such damage from occurring.

 

It is required to manage to prevent the upper and lower bearings of the gas spring from being damaged due to periodic injection.

 

 Before checking the gas spring, be sure to check whether the controller and external powers are in the 『OFF』 state. Also, take measures to prevent the controller and external powers from being turned 『ON』accidentally by other people. Always wear protective glasses when checking the gas pressure.

 

n  Diagnostics

 

①     Check whether the cover protecting the piston rod of the gas spring is damaged.

②     Check whether the surface of the gas spring piston rod is damaged.

③     Check if the pressure of the gas spring is appropriate.

Check the pressure in compliance with “10.1. Checking the gas spring pressure”.

④     Check if the BS joint assembled on the upper/lower part of the gas spring assembly unit is operating with excessive eccentricity and whether there is overheating or foreign substances in the bearing part.

 

n  Resolution

 

①    When the motor is overloaded due to the gas pressure drop, or the pressure decreases below the proper level, replenish nitrogen gas or replace the gas spring assembly unit.

②    Replace the bearing inside the BS joint if it is abnormal.

③    If you have any difficulty in handling, please contact our service department.

④    Carry out replenishing in compliance with “9.2. Replenishing the gas for gas spring”.

⑤    Comply with “9.4. Replacing the assembly unit of gas spring” for the pressure reference and replacement.
