維護(hù)與檢修 Maintenance and repair
【產(chǎn)品詳情圖片】
1.儲罐的使用與維護(hù)，應(yīng)按“壓力容器安全技術(shù)監(jiān)察規(guī)程”要求和本說明進(jìn)行。
The use and maintenance of the storage tank shall be carried out according to the requirements of the Pressure Vessel Safety Technical Supervision Regulations and these instructions
2.日常檢查與維護(hù) Daily inspection and maintenance
儲罐在運(yùn)行過程中，要經(jīng)常檢查安全閥、壓力表、液位計(jì)工作是否正常，閥門管路是否有泄漏，外部有無異常現(xiàn)象，發(fā)現(xiàn)問題及時(shí)處理。
During operation of the tank, check the safety valve, pressure gauge and liquid level meter regularly, whether the valve line is leaking, whether there is any abnormal phenomenon outside, and find the problem to be handled in time.
3.定期校驗(yàn) Regular verification
3.1安全閥整定壓力不大于2.27Mpa，每年至少校驗(yàn)一次，并加鉛封，作好記錄。
Safety valve setting pressure is not more than 2.27Mpa, at least once a year, and add seals, make a record.
3.2定期檢查夾層真空度，未裝低溫介質(zhì)的情況下真空度應(yīng)低于65Pa，裝有低溫介質(zhì)的情況下，真空度應(yīng)低于10Pa為合格。
Regularly check the sandwich vacuum, the vacuum should be less then 65Pa without vacuum medium; with a low temperature medium, the vacuum should be less than 10Pa for the pass.

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(jì)、安全閥應(yīng)投入使用外，其他閥門應(yīng)處于關(guān)閉狀態(tài)。當(dāng)儲罐壓力超過2.1Mpa時(shí)，開啟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.
