Please receive our sincere thanks for your purchase of our equipments. We manufacture in strict accordance with standards and craftsmanship, but will still cause accidents due to improper installation and use. The safety instructions in this manual are for the purpose of safe and correct use of this equipment, to prevent the harm to you or others from harm or damage, and once the wrong operation method is implemented, all the consequences arising therefrom are safety related. Please accept the instructions in this manual, and note the following:
1本设备属于特种设备，要设专职人员管理与操作，操作人员要经过培训持证上岗，否则由于误操作和使用，会造成危及生命安全的可能。
The equipment belongs to special equipment, which should be managed and operated by full-time personnel. Operators should be trained and certified to be on duty. Otherwise, it will be possible to endanger life safety due to misoperation and use.
2 本设备的安装、使用及维修应符合JB6898-1997《低温液体贮运设备 使用安全规则》的规定。本设备应放在室外、通风良好的场所。CO2有很强的窒息性，会引起窒息危险，甚至危及生命。
the installation, use and maintenance of the equipment shall conform to the provisions of JB6898-1997 "safe rules for the use of cryogenic liquid storage and transportation equipment". The equipment should be placed outdoors and well ventilated. CO2 has a strong asphyxiation, which can cause choking hazards and even life.
3 本设备贮存的是-40℃的低温液体，管道、阀门冻结堵塞时严禁用重物敲击、火烤或冷水喷淋等方法解冻，应用70～80℃干净无油的热空气、热氮气解冻。
this equipment is to 40 ℃ cryogenic liquid storage, pipe, valves, frozen jams it is forbidden to use heavy percussion, fire, or cold water spray method of thawing, application of 70 ~ 80 ℃ clean hot air, hot nitrogen release without oil.

液体的排放 liquid discharge
【产品详情图片】
2.4.1液体二氧化碳的正常排放是在储罐增压后，开启V2排液阀，V3回气阀，液体二氧化碳便流入汽化器汽化，供使用点使用。
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为满足排液过程的稳定压力，应按“储罐的增压”操作方法进行增压。
In order to meet the steady pressure of the drainage process, it should be pressurized according to the method of "pressurized tank".

储罐的增压 Tank pressurization
【产品详情图片】
当储罐向外供液又需要稳定排液压力时，可利用汽化器（另外配备）进行增压。其操作过程如下：
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开启V2排液阀，使液体二氧化碳汽化器汽化，开启V3回气阀（根据用户回气管路的设置，V3回气阀可置于常开状态）从汽化器分流出来的气体返回储罐上部，使储罐内增压。
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当储罐内压力达到2.1Mpa时，可暂时关闭V3回气阀。
When the tank pressure reaches 2.1Mpa, the valve can be temporarily closed V3 return gas valve.
2.3.3排液过程中，可通过控制V3回气阀的开度，使增压能力维持在压力稳定的水平。
During drainage, the degree of pressurization can be maintained at a pressure-stable level by controlling the opening of the V3 return valve.
