二氧化碳儲(chǔ)罐的長處
二氧化碳儲(chǔ)罐是儲(chǔ)存液態(tài)二氧化碳介質(zhì)的儲(chǔ)存壓力容器。
二氧化碳儲(chǔ)罐內(nèi)膽原料選用16MnDR，二氧化碳罐外膽原料為Q245R或者Q345R。
二氧化碳罐選用“組合、安全體系閥”運(yùn)用兩組安全閥一起作業(yè)，在安全閥定時(shí)校驗(yàn)時(shí)可關(guān)閉一側(cè)，另一側(cè)持續(xù)作業(yè)，保證二氧化碳罐的安全運(yùn)轉(zhuǎn)。
二氧化碳罐選用熱態(tài)下的珠光砂為絕熱材料并抽真空，公司以共同的技術(shù)保證質(zhì)量，以達(dá)到絕熱作用。
二氧化碳罐具有運(yùn)用壽命長、構(gòu)造緊湊、占地面積少、集中控制、操作和維修便利等特色。
二氧化碳罐的規(guī)劃壓力為2.2MPa

常見故障的處理 Common fault handling
【產(chǎn)品詳情圖片】
1.內(nèi)罐壓力異常長高 Inner tank pressure abnormally high
1.1可能是V3回氣閥開度過大或閥門失靈，應(yīng)減小閥門開度或檢修閥門。
May be V3 return valve opening is too large or valve failure, should reduce the valve opening or valve repair.
1.2可能是S1、S2安全閥失靈，到啟動(dòng)壓力不啟動(dòng)，應(yīng)檢查安全閥。
may be S1, S2 safety valve failure, to start the pressure does not start, check the safety valve.
1.3可能是壓力表指示不準(zhǔn)確，應(yīng)校驗(yàn)壓力表。
may be pressure gauge indicates inaccurate, should verify the pressure gauge.
2.液位計(jì)指示不真實(shí) Level gauge instructions are not true
2.1可能是液位計(jì)失靈，應(yīng)檢修液位計(jì)。
may be the level gauge failure, should be maintenance level gauge
2.2可能是液位計(jì)接頭處泄漏，應(yīng)檢修接頭連接處，排除泄漏。
It may be a leak at the head of the liquid level gauge. It should repair the connection of the joint and eliminate the leakage
3.蒸發(fā)率高，外殼體凝水結(jié)霜 High evaporation rate, the outer shell condensate frost
3.1可能是珠光砂未填實(shí)或下沉，應(yīng)補(bǔ)充珠光砂，重新抽真空。
may be unfilled or sinking of pearl sand, pearl sand should be added and re-evacuated.
3.2可能是真空度惡化，應(yīng)進(jìn)行真空檢漏，重新抽真空。
may be a deterioration of the vacuum, vacuum leak detection should be carried out, re-vacuum.
4.管道閥門液體流動(dòng)不暢或堵塞 pipeline valve fluid flow or blocked
可能是液體二氧化碳形成干冰的原因造成，應(yīng)停止使用，用熱空氣加溫管閥至?xí)惩橹?。May be caused by the formation of dry ice, should stop using, with hot air heating pipe valve until smooth.

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(chǔ)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(diǎn)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(yīng)按“儲(chǔ)罐的增壓”操作方法進(jìn)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".

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開啟V2排液閥，使液體二氧化碳汽化器汽化，開啟V3回氣閥（根據(jù)用戶回氣管路的設(shè)置，V3回氣閥可置于常開狀態(tài)）從汽化器分流出來的氣體返回儲(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排液過程中，可通過控制V3回氣閥的開度，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.
