維護(hù)與檢修 Maintenance and repair
【產(chǎn)品詳情圖片】
1.儲(chǔ)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(shuō)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(chǔ)罐在運(yùn)行過(guò)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(mén)管路是否有泄漏，外部有無(wú)異?，F(xiàn)象，發(fā)現(xiàn)問(wèn)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.

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.

2 儲(chǔ)罐的操作Tank operation
【產(chǎn)品詳情圖片】
儲(chǔ)罐的操作分為充液、貯存、增壓、排液等過(guò)程，每個(gè)過(guò)程必須做到：V6三通截止閥（連接安全閥）和V8液位計(jì)組合閥始終處于全開(kāi)狀態(tài)。罐內(nèi)壓力不應(yīng)高于2.16Mpa，壓力不應(yīng)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.
