一、气动氮气增压泵的特性：
1. Characteristics of Pneumatic Nitrogen Booster Pump:
1、驱动介质：多种气体驱动：紧缩空气、液化氮气和管道氮气、水蒸气。
1. Driving media: multi-gas drive: compressed air, liquefied nitrogen and pipeline nitrogen, water vapor.
2、输出流量大：只需0.3-0.69MPa紧缩空气驱动就可取得较大的输出流量。
2. Large output flow: only 0.3-0.69MPa compressed air drive can achieve a larger output flow.
3、自动保压：工作时，疾速往复工作，随着输出压力接近设定压力值时泵的往复运动速度减慢直至中止。并坚持这个压力，此时耗费能量很小，无热量产生， 无零件运动。当压力均衡突破后，气动增压泵自动开端工作到下一个均衡。
3. Automatic Pressure Maintenance: When working, the reciprocating speed of the pump slows down until it stops as the output pressure approaches the set pressure value. And adhere to this pressure, at this time energy consumption is very small, no heat generation, no part movement. When the pressure balance breaks through, the pneumatic booster pump automatically starts to work to the next equilibrium.
4、材质优秀：高压局部材质为不锈钢。高压柱塞材质为不锈钢，并采用双层密封。
4. Excellent material: High-pressure local material is stainless steel. The material of high pressure plunger is stainless steel and double-layer seal is adopted.
5、维护简单：气动增压泵的零件及密封少，维护简单且本钱低。相同系列泵的一切"O"型圈，维修包易损部件可互相交换，大大降低了维修本钱。气动增压泵出厂前已加注光滑剂，工作时无需外部光滑。
5. Simple maintenance: Pneumatic booster pump has fewer parts and seals, simple maintenance and low cost. All O-rings of the same series of pumps can be exchanged between the vulnerable parts of the repair kit, which greatly reduces the cost of maintenance. The pneumatic booster pump has been injected with smoothing agent before leaving the factory, so it does not need external smoothing when working.
