液體的儲(chǔ)存 liquid storage
液體二氧化碳的儲(chǔ)存屬于帶壓（壓力不低于0.8Mpa）儲(chǔ)存。儲(chǔ)存期間除壓力表、液位計(jì)、安全閥應(yīng)投入使用外，其他閥門(mén)應(yīng)處于關(guān)閉狀態(tài)。當(dāng)儲(chǔ)罐壓力超過(guò)2.1Mpa時(shí)，開(kāi)啟V7排氣閥降壓。但應(yīng)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.

儲(chǔ)罐的增壓 Tank pressurization
【產(chǎn)品詳情圖片】
當(dāng)儲(chǔ)罐向外供液又需要穩(wěn)定排液壓力時(shí)，可利用汽化器（另外配備）進(jìn)行增壓。其操作過(guò)程如下：
The carburetor (available separately) can be used for boosting when the reservoir is supplied externally and requires stable discharge pressure. The operation is as follows:
2.3.1開(kāi)啟V2排液閥，使液體二氧化碳汽化器汽化，開(kāi)啟V3回氣閥（根據(jù)用戶回氣管路的設(shè)置，V3回氣閥可置于常開(kāi)狀態(tài)）從汽化器分流出來(lái)的氣體返回儲(chǔ)罐上部，使儲(chǔ)罐內(nèi)增壓。
Open the V2 drain valve to vaporize the liquid carbon dioxide vaporizer and open the V3 return valve (the V3 return valve can be normally open depending on the return air line of the user). The gas diverted from the vaporizer returns to the upper part of the tank , So that the pressure tank.
2.3.2當(dāng)儲(chǔ)罐內(nèi)壓力達(dá)到2.1Mpa時(shí)，可暫時(shí)關(guān)閉V3回氣閥。
When the tank pressure reaches 2.1Mpa, the valve can be temporarily closed V3 return gas valve.
2.3.3排液過(guò)程中，可通過(guò)控制V3回氣閥的開(kāi)度，使增壓能力維持在壓力穩(wěn)定的水平。
During drainage, the degree of pressurization can be maintained at a pressure-stable level by controlling the opening of the V3 return valve.
