1. System composition

　　小型高纯气体增压泵是在一个由控制部分和工作部分组成的两级增压系统中工作的。工作部分可分为:低压工作区、a级高压工作区和两个高压工作区，每个工作区由缸体、缸体腔、活塞和密封件等组成。采用密封装置实现各工位的气密性和自润滑功能。控制部分由加热冷却系统的压缩气体的自动换向机构的一部分,单向空气阀控制高压缸的排气等,主要实现冷却,往复换向,压力控制和超压保护设备,实现设备的安全可靠连续增压。

　　The small high purity gas booster pump works in a two-stage booster system which is composed of a control part and a working part. The working part can be divided into low-pressure working area, A-level high-pressure working area and two high-pressure working areas. Each working area is composed of cylinder body, cylinder cavity, piston and seal. The sealing device is used to realize the air tightness and self lubrication function of each station. The control part is a part of the automatic reversing mechanism of the compressed gas of the heating and cooling system, and the one-way air valve controls the exhaust of the high-pressure cylinder. It mainly realizes the cooling, reciprocating reversing, pressure control and overpressure protection equipment, and realizes the safe, reliable and continuous pressurization of the equipment.

　　2. Process flow

　　(1)阶段增压:增压装置开始工作后,驱动压缩气体通过空气控制阀进入低压缸的气室,并打开排气口左气室的低压缸(此时,气室与大气中)。驱动压缩气体和空气分别作用在低压活塞的两侧，两个活塞之间的压差产生压差。由于驱动压缩气体的压力大于空气的压力，它推动低压活塞在低压缸内向左移动，带动传动轴移动。连接到驱动轴高压活塞向左移动水平的同时,高水平的压力室容积减少,空腔的高纯度气体压力也逐渐增加,当压开云在线官方于设定值时,排气阀打开,压缩高纯度气体进入二次高压气瓶,当低压活塞运行到更左端,增压的水平。换向器工作，启动两级增压。

　　(1) First stage pressurization: after the supercharging device starts to work, the compressed gas is driven to enter the air chamber of the low-pressure cylinder through the air control valve, and the low-pressure cylinder of the left air chamber of the exhaust port is opened (at this time, the air chamber and the atmosphere). The driving compressed gas and air act on both sides of the low-pressure piston respectively, and the pressure difference between the two pistons produces the pressure difference. Because the pressure of driving compressed gas is greater than that of air, it pushes the low-pressure piston to move left in the low-pressure cylinder, and drives the transmission shaft to move. When the high-pressure piston connected to the drive shaft moves to the left, the volume of the high-level pressure chamber decreases, and the pressure of the high-purity gas in the cavity gradually increases. When the pressure is higher than the set value, the exhaust valve opens, and the compressed high-purity gas enters the secondary high-pressure cylinder. When the low-pressure piston moves to the left end, the pressure is increased. The commutator works and starts two-stage pressurization.

　　(2)二级增压:驱动压缩气体的控制下逆转机制自动换向,留给了低压缸腔填充驱动气体,打开低压缸燃烧室出口的同时,适当的工作推动气腔压缩空气后逃离线加热部分的进气口与相应的散热翼,取暖和冷却。低压缸活塞在驱动压缩气体的作用下，带动传动轴向右，启动两级增压。同时打开增压缸的进风口，吸入增压的高纯气体。当低压气缸活塞运行到更右边时，两级增压结束并完成—一个工作循环。

　　(2) Secondary pressurization: under the control of the driving compressed gas, the reversing mechanism automatically reverses, leaving the low-pressure cylinder cavity filled with the driving gas. When opening the combustion chamber outlet of the low-pressure cylinder, the appropriate work pushes the compressed air in the air cavity to escape from the air inlet of the heating part of the line and the corresponding cooling wing for heating and cooling. Under the action of driving compressed gas, the piston of low pressure cylinder drives the transmission shaft to the right and starts two-stage pressurization. At the same time, open the air inlet of the booster cylinder, and inhale the high-purity pressurized gas. When the piston of low-pressure cylinder runs to the far right, the two-stage pressurization is completed and a working cycle is completed.

　　(3)连续函数:在合并后的压缩气体自动换向控制机制和单向空气阀控制高压缸的排气的低压活塞加压设备驱动器驱动轴,从而实现自动换向和连续往复运动,从而实现连续额定的输出高压和高纯度气体来满足用户的需求。

　　(3) Continuous function: the combined compressed gas automatic reversing control mechanism and one-way air valve control the drive shaft of the low-pressure piston pressurization device for the exhaust of the high-pressure cylinder, so as to realize automatic reversing and continuous reciprocating motion, so as to realize the continuous rated output of high-pressure and high-purity gas to meet the needs of users.

　　(4)压力控制和超压保护:设备具有输出气体压力控制和系统超压保护功能。当高压储气罐或其他气体设备的压力达到设定值时，控制二次高压缸排气的单向气阀将切断管道，停止供气。当设备停机时，单向气阀还可以切断管路，防止高压储气罐等气体供应到设备上。当设备系统压力因特殊情况超过规定值时，超压保护装置将关闭空气控制阀，停止驱动输入的压缩气体，防止进一步增压失效和事故。

　　(4) Pressure control and overpressure protection: the equipment has the functions of output gas pressure control and system overpressure protection. When the pressure of the high-pressure air storage tank or other gas equipment reaches the set value, the one-way air valve controlling the exhaust of the secondary high-pressure cylinder will cut off the pipeline and stop the air supply. When the equipment is shut down, the one-way air valve can also cut off the pipeline to prevent the high-pressure air tank and other gases from being supplied to the equipment. When the pressure of the equipment system exceeds the specified value due to special circumstances, the overpressure protection device will close the air control valve and stop driving the input compressed gas to prevent further pressurization failure and accident.
