1．增压前准备准备一个手动操作的泵:
1. Prepare a manually operated pump before pressurization:
★连接管路(驱动气源管路、液体介质输入管路和高压输出管路)。★打开驱动气源开关，缓慢调节驱动气源压力，使泵启动。
★ 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.
★设置驱动气压力。
★ set the driving air pressure.
2．增压过程泵的升压过程∶
2. Boosting process of booster pump:
★当驱动活塞背向泵头运行时，出口单向阀关闭，入口单向阀打开将液体吸入泵内，流体被吸入泵头;活塞运动到后端底部时触动循环阀换向。
★ 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.
★循环阀换向后活塞向另一端运动，使活塞杆压缩泵头内的流体，入口单向阀关闭，出口单向阀打开，流体被泵出;活塞运动到前端底部时触动循环阀换向。★活塞往复运动，流体持续被泵出到泵出口端，实现后端
★ 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．到达压力并保压增压。泵达到输出压力并保压的过程∶★当泵输出压力与气源驱动压力按输出比平衡后;泵停止动作。★泵保持输出压力，此时泵不动作，没有气源消耗，也没有发热。
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.
★如果泵出口压力下降，泵重新自动启动。
★ if the pump outlet pressure drops, the pump will restart automatically.
