INFLATING & PRESSURISING GAS SPRINGS
Inflating process of gas springs connected for equal pressure
• Confirm that the pressure reducer has been connected to the nitrogen bottle and adjust the output pressure to 150 to 155 bar (15 to 1.5 MPa).
• Connect the adapters to the inflating unit.
• Connect the inflating unit to the control panel.
• Close the pressure reducer.
• Open the nitrogen bottle.
• When the inflating gauge indicates the pressure that you need, please wait for a while (about 10 seconds), the piping system pressure will stabilize.
• Close the nitrogen bottle.
• Open discharging valve to release the pressure.
• Remove the inflating unit from the control panel.
Control block with G1/8″ adapter
To inflate the piping system with standard G1/8″ adapter, you can use standard inflating units and G1/8″ adapter.
Control block with CEJN adapter
You can use self-lock fast coupling adapter to connect it.
Notice : The fast coupling should be ordered with inflating units separately. The pressure reducer should be ordered separately.
Ajust the pressure of gas springs
The inflating device is designed to pressurize and depressurize gas springs
Use of the device as a pressure tester is not recommended, as each test result leads to a loss of pressure of approximately 10 %.
The pin ø4 mm is designed to depressurize a gas spring, but is not required for pressurizing.
Each pressurising kit (Code 841046/000) includes :
• 1 pressurizing assembly (Code : A63295) with gauge 0-250 bar + flexible hose (2m) + valve spanner.
• 1 adapter MM M33x1,5 – G1/8’’ + 1 pin ø4 to direct inflating in G1/8’’ threads (Code : 831050/000)
• 1 adapter MF 1/16NPS – G1/8’’ (Code : 831052/000)
• 1 adapter MF M6 – G1/8’’ type A (Code : 831101/000)
• 1 adapter MF M6 – G1/8’’ type B (Code : 831113/000)
MOUNTING A – Inflating directly with the adapter
MOUNTING B – Inflating with adapter and tip

Procedure
• Depressurize the gas spring completely by depressing the valve with the special QUIRI tool, whilst keeping the piston rod of the gas spring fully extended.
• Refill the gas spring to the required pressure level (eg. 100 bar).
• Check the valve tightness with a drop of oil inside the pressuring orifice.
• If the valve is not tight, replace it with new one.
• Do not forget to indicate the new inflating pressure on the gas spring body and identify if with a blue adhesive strip if the new pressure is lower than 150 bar.
INFLATING GAS SPRINGS WITH 2 NITROGEN BOTTLES
Example : bottle A contains 13.5 MPa, use bottle B to add 1.5 MPa. You can use bottle A until bottle B is lower than 15Mpa.
Inflating advice :
INFLATION OF CONTROL PANEL EQUIPED WITH STAUBLI CONNECTOR WITH 2 NITROGEN BOTTLES
THE ADVANTAGE OF THAT EQUIPMENT IS THE OPTIMAL USE OF NITROGEN BOTTLE CONTENTS
Inflating advice :
• First of all, setup the inflating pressure on the pressure reducer.
• Connect the STAUBLI connector to the control panel.
• Open valve A and close valve B, then fill the gas spring with maximum pressure from the first bottle.
• Close valve A and open valve B, then fill the gas spring with about 155 bar.
• Close valve B and the valves on the nitrogen bottle.
• Open discharging valve on the collector to remove pressure.
• Disconnect the STAUBLI connector by pushing the knob.
• WARNING! : NEVER REMOVE THE CONNECTOR WHILE UNDER PRESSURE.
