Co2 extraction machine uses supercritical carbon dioxide to extract compounds instead of organic solvents, which has important applications in food and medicine industries.As a common extraction device, understanding the considerations during the operation of co2 extraction machine can reduce operational errors, extend the service life of the instrument, and improve test efficiency. This article mainly introduces what should be noticed when using a co2 extraction machine.
Precautions for the use of co2 extraction machine
Operation requirements of co2 extraction machine
(1)co2 extraction machine is a high-pressure flow device, which can only be operated by operators familiar with the system process.
(2) during the high-pressure operation of co2 extraction machine, the operator shall not leave his/her post. In case of abnormal situation of co2 extraction machine, the operator shall shut down the main power immediately to check.
(3) before starting the co2 extraction machine pump system, check whether the lubrication condition conforms to the instructions. The packing cap should not be too loose or too tight.
(4) the required value should be adjusted in advance before the operation of the electrode point pressure gauge of co2 extraction machine, otherwise the pump will stop automatically or the electrode will fail to exceed the pressure.
(5) the co2 extraction machine adopts R22 freon for refrigeration. Check the refrigerating oil before starting. It has been adjusted under normal conditions.
(6) freon can be recovered without using co2 extraction machine for a long time. The specific operation is: close the supply valve and start for about 5 minutes, and the low-pressure meter can be shut down if it is less than 0.1mpa.
(7) frequently check whether the joints of the co2 extraction machine are loose.
(8) the co2 extraction machine pump shall be replaced with lubricating oil within a certain time.
(1) all types of personnel working in the co2 extraction machine workshop shall strictly comply with this provision.
(2) operators of co2 extraction machine shall have certain theoretical basis and skills of electronic control, mechanical and instrument operation skills, refrigeration and heating knowledge.
(3) the operator of co2 extraction machine shall be familiar with the structural performance of the device, understand the physical and chemical properties of co2, understand the operation process of co2 extraction machine and the auxiliary equipment of the device.
(4) the operator of co2 extraction machine shall be familiar with the relevant provisions of national pressure vessels and the knowledge of pressure vessels and their accessories.
(5) the operators of co2 extraction machine must be trained in the operation of special equipment and hold the special equipment operation license issued by the local competent authority to operate the device.
(6) (1) the environment of co2 extraction machine and articles must be neat and clean, and the safe passage must be free from obstacles.
(7) (2) disassembly of co2 extraction machine power system, control system, electrical components and frequency converter must be approved by the professional and technical personnel.
(8) non-operators or non-commissioning personnel of the workshop are strictly prohibited to operate the co2 extraction machine.
(9) all the equipment and safety facilities in the extraction workshop shall not be dismantled or moved without the permission of relevant departments.
(10) to disassemble and repair co2 extraction machine, it is necessary to pull the brake and power off.
(11) it is strictly prohibited to bring dangerous and inflammable goods into the construction site of co2 extraction machine.
(12) it is strictly prohibited for anyone to open or close the valve, pump and other equipment related to co2 extraction machine at will;The operator shall ensure that each step of the operation of the co2 extraction machine is correct and correct.
(13) the fire fighting and safety facilities in the co2 extraction machine workshop are complete and in effect.
