充液的操作 filling operation
【标题】
充液分为充液和补充充液。
充液的操作如下:
Filling fluid is divided into the first filling and filling fluid.
The first filling operation is as follows:
2.1.1 储罐吹除置换干净达到要求后,将充液管线与储罐的充液接头连接,液位计组合阀处于平衡状态准备充液。
After the tank blows off to replace the cleanliness meets the requirements, the filling liquid line is connected with the liquid filling joint of the tank, and the liquid level gauge combination valve is in an equilibrium state to be filled.
2.1.2充入与液体二氧化碳纯度相同的气体,使罐内压力达到0.8 Mpa以上,方可进行充液。 filled with the same purity of liquid carbon dioxide gas, the tank pressure reached 0.8 Mpa above, before filling.
2.1.3 将充液管线接通槽车,先开启V5残液阀,排出管线内的杂质气体后,再开启V1进液阀和V7排气阀,V8液位计组合阀处于全开状态,显示液位计读数进行充液。
The filling liquid line connected tanker, first open the V5 raffinate valve, exhaust gas impurities within the pipeline, and then open the V1 inlet valve and V7 exhaust valve, V8 level gauge combination valve is fully open state, Display level meter readings are filled.
2.1.4 在充液过程中,当液位计指示液位接近标定值时,可间断开启V4充满指示阀,如有液体喷出,应立即停止充液,关闭V4充满指示阀。
During the filling process, when the liquid level gauge indicates the liquid level approaches the calibration value, the V4 may be intermittently opened to indicate the valve. If any liquid is ejected, liquid filling should be stopped immediately and the V4 valve should be closed.
2.1.5关闭V1进液阀和V7排气阀,打开V5残液阀,拆下充液管线,充液结束。
补充充液的操作与充液的操作方法相似,不同点是补充充液时一开始就可以大量充液。
Close the V1 inlet valve and the V7 exhaust valve, open the V5 residual valve, remove the filling line, and fill with liquid.
The procedure for replenishing the priming solution is the same as for the first priming procedure, except that the priming solution can be replenished extensively from the beginning.

常见故障的处理 Common fault handling
【产品详情图片】
1.内罐压力异常长高 Inner tank pressure abnormally high
1.1可能是V3回气阀开度过大或阀门失灵,应减小阀门开度或检修阀门。
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安全阀失灵,到启动压力不启动,应检查安全阀。
may be S1, S2 safety valve failure, to start the pressure does not start, check the safety valve.
1.3可能是压力表指示不准确,应校验压力表。
may be pressure gauge indicates inaccurate, should verify the pressure gauge.
2.液位计指示不真实 Level gauge instructions are not true
2.1可能是液位计失灵,应检修液位计。
may be the level gauge failure, should be maintenance level gauge
2.2可能是液位计接头处泄漏,应检修接头连接处,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.蒸发率高,外壳体凝水结霜 High evaporation rate, the outer condensate frost
3.1可能是珠光砂未填实或下沉,应补充珠光砂,重新抽真空。
may be unfilled or sinking of pearl sand, pearl sand should be added and re-evacuated.
3.2可能是真空度恶化,应进行真空检漏,重新抽真空。
may be a deterioration of the vacuum, vacuum leak detection should be carried out, re-vacuum.
4.管道阀门液体流动不畅或堵塞 pipeline valve fluid flow or blocked
可能是液体二氧化碳形成干冰的原因造成,应停止使用,用热空气加温管阀至畅通为止。May be caused by the formation of dry ice, should stop using, with hot air heating pipe valve until smooth.
