二氧化碳儲罐壓力不能低于1.4MPa工作，二氧化碳液體在低于0.7MPa時(shí)會(huì )形成干冰，一旦形成干冰，儲罐就很麻煩了，里面二氧化碳液體凝結成冰，將很難解決。

The pressure of the carbon dioxide storage tank cannot be lower than 1.4MPa. When the pressure of the carbon dioxide liquid is lower than 0.7MPa, dry ice will form. Once dry ice forms, the storage tank will be very troublesome, and the carbon dioxide liquid inside will condense into ice, which will be difficult to solve.

你所說(shuō)的是二氧化碳在使用過(guò)程中壓力不斷降低，為了防止不斷降低壓力，你現在需要增加一套二氧化碳子增壓系統，此系統構成有兩個(gè)部分；

What you are talking about is that the pressure of carbon dioxide continuously decreases during use. In order to prevent continuous pressure reduction, you now need to add a set of carbon dioxide sub pressurization system, which consists of two parts;

1.自增壓器；可以采用空溫式汽化器，汽化量30立方的就可以。

1. Self booster; An air temperature vaporizer can be used, with a vaporization capacity of 30 cubic meters.

2.增壓閥；在增壓器氣體出口安裝一個(gè)增壓閥。

2. Boosting valve; Install a booster valve at the gas outlet of the booster.

3.壓力表

3. Pressure gauge

4.閥

4. Safety valve

連接方式是；由進(jìn)液管路或者出液管路連接一根管，連接外置的增壓器，再依次連接以上的部件，終的閥之后的出氣管，也叫回氣管，連接儲罐的放空管上面，這樣就能解決壓力不夠的問(wèn)題。

What is the connection method; Connect a pipe from the inlet or outlet pipeline to the external booster, and then connect the above components in sequence. After the final safety valve, the outlet pipe, also known as the return pipe, is connected to the vent pipe of the storage tank. This can solve the problem of insufficient pressure.

另外，希望你考慮檢查一下壓力表是不是已經(jīng)壞了。

Also, I hope you first consider checking if the pressure gauge is already broken.

（1）二氧化碳密度比空氣大，所以覆蓋在可燃物表面隔絕了空氣；二是常溫下為氣態(tài)，易揮發(fā)，不污染物體；

(1) Carbon dioxide has a higher density than air, so it covers the surface of combustible materials and isolates the air; Secondly, it is in a gaseous state at room temperature, easily volatile, and does not pollute objects;

（2）二氧化碳既不能燃燒也不支持燃燒，且密度比空氣大，所以覆蓋在可燃物表面隔絕了空氣；

(2) Carbon dioxide neither burns nor supports combustion, and its density is higher than air, so it covers the surface of combustible materials and isolates the air;
