Application scope and characteristics of liquid oxygen low temperature storage tank
Date: Dec 01, 2019
One cubic meter of liquid oxygen can replace 130 gas cylinders. It can replace the daily round-trip transportation with gas cylinders and save a lot of human and material resources.
Widely used in gas industry, hospital, metal smelting and other users with large gas consumption, it is the best product to achieve centralized gas supply.
The utility model has the advantages of long service life, compact structure, small floor area, centralized control, convenient operation, etc.
Operating procedures for liquid oxygen storage tank
1. Check whether the pressure in the low temperature liquid oxygen storage tank is normal (normal range: 0.45MPa ～ 0.65Mpa) When the pressure of low-temperature storage tank is too high, open the vent valve to depressurize. When the tank pressure is too low, open the booster valve to pressurize.
2. Open the air supply valve behind the vaporizer of liquid oxygen cryogenic storage tank, and the gas station will start to work.
3. The personnel on duty must regularly patrol the liquid oxygen storage tank and record at least twice a day.
4. Personnel on duty must supervise on site during liquid filling, make statistics of liquid filling quantity of low temperature liquid oxygen storage tank and record.
5.The personnel on duty shall pay close attention to the liquid level display of the liquid oxygen storage tank during patrol inspection.When the indication value of the liquid level display of No. 1 storage tank is less than 400mm, it shall be switched to No. 2 storage tank for nitrogen supply in time.
When the indication value of liquid level display of No.2 storage tank is lower than 2500mm, it shall be reported to the team leader in time, and the team leader shall contact the liquid oxygen supplier to supply liquid nitrogen after confirmation.
6. When the vaporizer of liquid oxygen cryogenic storage tank is frosted seriously, defrosting work shall be done in time.
