Nitrogen filling method for excavator crusher

Nitrogen filling method for excavator crusher:

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 screw plug of the crushing hammer, install the three-way valve on the charging valve of the upper body. (ensure O-ring is installed on the three-way valve)

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

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

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

After the inflation hose is removed from the three-way valve, the cap of the three-way valve shall be fastened.

Turn the three-way valve handle clockwise to check the inflation pressure in the upper body again.

Remove the inflation hose from the three-way valve.

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

When the three-way valve handle is turned clockwise, the pressure value in the upper 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, so that the air pressure is discharged from the upper body; When the appropriate and correct pressure value is displayed on the pressure gauge, the regulator shall be closed clockwise. If the pressure is too high, the crushing hammer will not work normally. Ensure that the air pressure meets the specified pressure value and that the three-way valve is equipped with an O-ring.
