1. Before using the accumulator nitrogen-filling tool, first perform debugging to check the oil level. The nitrogen-filling tool in the closed state must be filled with oil until the level gauge shows that the oil has reached its peak. During the working process, the display of the level gauge will show the fluctuation of the liquid level.
2. Connect the accumulator nitrogen filling tool and the nitrogen bottle through a hose, and connect the nitrogen gas valve and the nitrogen inlet of the accumulator nitrogen filling tool by a screw connection.
3. Connect the nitrogen accumulator of the accumulator with the accumulator that requires nitrogen, and connect the nitrogen outlet of the nitrogen accumulator and the accumulator nitrogen tool through a hose.
4. Before the accumulator nitrogen charging tool is connected to the power source, make sure that the main switch on the control panel is at position O. At this time, the nitrogen-charged booster tool is in a closed state.
5. Start the accumulator nitrogen charging tool by turning the main switch on the control panel, enter the work, set the relief valve, and set the pressure switch.
6. When the motor is turned on by the start switch S1 at the beginning, the residual gas in the pump will make the pump make noise. It will take at least one minute for the pump to sound normal when the gas is expelled from the pump.
7. Start filling the accumulator with nitrogen. The nitrogen entering the piston accumulator and the accumulator are charged automatically. Open the stop valve on the nitrogen bottle (about half a turn), wait until the nitrogen bottle and the nitrogen-filled energy storage
The pressure between the devices reaches equilibrium (you can judge whether the pressure has reached equilibrium by listening to whether the sound stops.
8. After the nitrogen filling is completed, after the required nitrogen filling pressure is reached, after the nitrogen filling is automatically stopped, the gas valve of the nitrogen bottle is closed, and the nitrogen valve of the accumulator is closed using the nitrogen filling detection device.
9, do a good job cleaning and cleaning.
