1. Prepare a manually operated pump before pressurization:
★ connect the pipeline (drive air source pipeline, liquid medium input pipeline and high-pressure output pipeline). ★ turn on the drive air source switch and slowly adjust the drive air source pressure to start the pump.
★ set the driving air pressure.
2. Boosting process of booster pump:
★ when the driving piston runs away from the pump head, the outlet check valve is closed and the inlet check valve is opened to suck the liquid into the pump and the fluid is sucked into the pump head; When the piston moves to the bottom of the rear end, it touches the reversing of the circulating valve.
★ when the circulating valve is reversed, the piston moves to the other end, so that the piston rod compresses the fluid in the pump head, the inlet check valve is closed, the outlet check valve is opened, and the fluid is pumped out; When the piston moves to the bottom of the front end, it triggers the reversing of the circulating valve. ★ the piston moves back and forth, and the fluid is continuously pumped out to the outlet end of the pump to realize the rear end
3. Reach the pressure and maintain the pressure for pressurization. The process when the pump reaches the output pressure and maintains the pressure: ★ when the pump output pressure and the air source driving pressure are balanced according to the output ratio; The pump stops. ★ the pump maintains the output pressure. At this time, the pump does not act, there is no air consumption and no heating.
★ if the pump outlet pressure drops, the pump will restart automatically.
