1、操作前的準備 Preparation before operation
【產(chǎn)品詳情圖片】
1.1 操作者應按本說明書要求及有關文件進行操作。The operator shall follow the instructions and related documents to operate.
1.2正式投入使用前，用干燥的CO2氣體對整個系統(tǒng)進行吹除置換，吹除置換所用的氣體純度不低于充裝介質(zhì)的純度。Formally put into use before the use of dry CO2 gas blowing the entire system replacement, purge replacement gas purity of not less than the purity of the filling

液體的儲存 liquid storage
液體二氧化碳的儲存屬于帶壓（壓力不低于0.8Mpa）儲存。儲存期間除壓力表、液位計、安全閥應投入使用外，其他閥門應處于關閉狀態(tài)。當儲罐壓力超過2.1Mpa時，開啟V7排氣閥降壓。但應注意：內(nèi)罐的壓力不得降至低于0.8Mpa，否則將引起液體二氧化碳轉(zhuǎn)變?yōu)楦杀?br>Liquid carbon dioxide storage with pressure (pressure not less than 0.8Mpa) storage. During the storage, the pressure gauge,level gauge, safety valve should be put into use, the other valves should be closed. When the tank pressure exceeds 2.1Mpa, open the V7 exhaust valve buck. However, it should be noted that the pressure inside the tank must not drop below 0.8Mpa, otherwise liquid carbon dioxide will be converted to dry ice.

2 儲罐的操作Tank operation
【產(chǎn)品詳情圖片】
儲罐的操作分為充液、貯存、增壓、排液等過程，每個過程必須做到：V6三通截止閥（連接安全閥）和V8液位計組合閥始終處于全開狀態(tài)。罐內(nèi)壓力不應高于2.16Mpa，壓力不應低于0.8Mpa .
The operation of the tank is divided into filling, storage, pressurization, drainage and other processes, each process must be: V6 three-way valve (connecting safety valve) and V8 level gauge combination valve is always in the fully open state. Tank maximum pressure should not exceed 2.16Mpa, the minimum pressure should not be less than 0.8Mpa.

液體的排放 liquid discharge
【產(chǎn)品詳情圖片】
2.4.1液體二氧化碳的正常排放是在儲罐增壓后，開啟V2排液閥，V3回氣閥，液體二氧化碳便流入汽化器汽化，供使用點使用。
The normal discharge of liquid carbon dioxide is after pressurization of the tank, open the V2 drain valve, V3 return valve, the liquid carbon dioxide will flow into the vaporizer vaporization for use point.
2.4.2為滿足排液過程的穩(wěn)定壓力，應按“儲罐的增壓”操作方法進行增壓。
In order to meet the steady pressure of the drainage process, it should be pressurized according to the method of "pressurized tank".
