首先钢瓶内得气体高压力不会超出14MPa，要把压力增压到20MPa那么就要压缩钢瓶内得气体，在这就要牵涉到几个问题，
First, the maximum pressure in the cylinder will not exceed the 14MPa. To pressurize the pressure to 20MPa, the gas in the cylinder must be compressed. In this case, there are several problems involved.
1：气体纯度问题，特别是做试验时对气体纯度要求很高如5个九得氮气，着样就要使用气驱气体增压泵（台州菲恩特气体增压泵），气驱气体增压泵有个好处就是驱动缸和增压缸分开，不影响气体纯度不影响试验效果。
1: the purity of gas, especially when the purity of the gas is very high, such as 5 nine nitrogen, the gas drive gas supercharging pump (Taizhou Phoenix gas booster pump) is used. The benefit of the gas drive gas supercharging pump is that the driving cylinder and the turbocharged cylinder are separated, and the purity of the gas body does not affect the test effect.
2：安全系数，现在随着科技得进步对被增压气体得种类需求越来越多，出现了很多钟危险危害气体，这种气体不能接触高温或者火花，这时也要选择菲恩特气体增压泵，增压泵用空气作为动力源不产生电火花，驱动得空气还可用来给增压泵降低温度，可以是用到各个危险场合。现在气体纯度和安全都能保证了就要选择型号了，钢瓶内得气体可以选择ZTA40气体增压泵来增压（ZTA40气体增压泵是增压泵和空压机得气体成40:1得关系，如果空压机为0.6MPa那么增压后得气体为24MPa）。
2: safety factor, now with the progress of science and technology to be more and more demand for the type of pressurized gas, there are many bell dangerous gas, this gas can not contact high temperature or spark, at this time, it is also necessary to choose the turbocharged gas booster pump, the pressurized pump air as the power source does not generate electric spark, driving the air is also available. Used to reduce the temperature of the booster pump can be used in all dangerous situations. Now the gas purity and safety can guarantee the choice of the model, the gas can be selected in the cylinder ZTA40 gas booster pump to supercharge (ZTA40 gas booster pump is a pressurized pump and air compressor gas into 40:1 relationship, if the air compressor is 0.6MPa then the gas is 24MPa).
注意事项：
Matters needing attention：
1.进入气体增压泵系统的气体或液体必须是纯净的经过滤的清洁高纯度气体（气动增压泵分为气体增压与液体增压）
1. the gas or liquid entering the gas booster pump system must be pure, filtered clean high purity gas (pneumatic supercharging pump is divided into gas turbocharging and liquid pressurization)
2.增压泵前需经150目及以上过滤器进行过滤，以免造成进口通道阻塞或损坏增压泵（针对高压泵这点很重要）
2. before the booster pump needs to be filtered by 150 or more filters, so as not to cause obstruction or damage to the inlet channel of the booster pump (for high pressure pump is very important).
3.系统配有冷却装置，如果温度过高，可以采取冷却水进行快速冷却
3. the system is equipped with cooling device. If the temperature is too high, cooling water can be used for rapid cooling.
4.进入增压泵系统气体驱动缸的空气必须是纯净的经过滤的压力稳定的气体，其压力可以通过普通调压阀进行调节（驱动气压力一般在2-8bar）
4. the air in the gas driven cylinder of the pressurized pump system must be pure, filtered, pressure stable gas, and its pressure can be adjusted by the ordinary pressure regulating valve (the driving gas pressure is generally at 2-8bar).
5.进行压力调节时，首先要缓慢进行，应注意观察高压气体增压泵系统的压力表的显示压力，不要超压
5. when carrying out pressure regulation, first of all, we must proceed slowly. We should pay attention to the pressure of the pressure gauge of the high-pressure gas booster pump system, not overpressure.
