How to fill nitrogen into excavator hammer

Nitrogen charging method for hydraulic hammer of excavator;

After connecting the pressure gauge to the three-way valve, turn the handle of the three-way valve counterclockwise.

Connect the inflation hose to the nitrogen cylinder.

After removing the plug of hydraulic hammer, install the three-way valve on the inflation valve of the upper body. (Make sure that the three-way valve is equipped with an O-ring)

Connect the other end of the inflation hose to the three-way valve.

Turn the valve handle on the nitrogen bottle counterclockwise to release nitrogen (N2), and then slowly turn the handle of the three-way valve clockwise to the specified set inflation pressure.

Turn the handle of the three-way valve counterclockwise to close the three-way valve, and then turn the handle of the valve on the nitrogen bottle clockwise to close the nitrogen.

After the inflatable hose is removed from the tee, tighten the cover of the tee.

Turn the handle of the three-way valve clockwise and check the inflation pressure of the upper body again.

Remove the inflation hose from the three-way valve.

Install the three-way valve tightly on the charging valve.

When the handle of the three-way valve is turned clockwise, the pressure value in the upper valve body will be displayed on the pressure gauge.

If the nitrogen pressure is low, repeat steps 1 to 8 until the pressure rises to the specified air pressure value.

If the nitrogen pressure is too high, slowly turn the regulator on the three-way valve counterclockwise to discharge the air pressure from the upper body; When the appropriate and correct pressure value is displayed on the pressure gauge, the regulator should be closed clockwise. If the pressure is too high, hydraulic hammer will not be able to work normally. Ensure that the air pressure meets the specified pressure value and that the three-way valve is equipped with an O-ring.
