1. What is the normal pressure of an oxygen bottle?
Oxygen bottles are pressure vessels that store high-pressure oxygen. Therefore, they are generally equipped with a pressure gauge for measuring and Display the pressure in the oxygen system to ensure the stability and safety of oxygen supply. So what is the normal pressure of the oxygen cylinder?
Generally speaking, the pressure of an oxygen cylinder has nothing to do with the volume of the cylinder. Whether it is a 4-liter, 10-liter or 40-liter cylinder, the pressure is the same when the cylinder is full. The pressure of a conventional oxygen cylinder The upper limit is 15Mp, which is 147 atmospheres when converted to atmospheric pressure. The pressure inside a conventionally filled cylinder should be around 12~15Mp. As the oxygen cylinder is used, the pressure will gradually decrease.
2. The oxygen tank cannot be used if the pressure is lower than the certain value
The pressure in the oxygen tank will decrease with the use of oxygen. Generally, in order to prevent dust from entering, which will affect the next charging. The oxygen in the oxygen bottle will not be used up, so what is the lower pressure of the oxygen bottle before it can be used?
According to the relevant provisions of the “Gas Cylinder Safety Inspection Regulations”, the gas in the oxygen cylinder cannot be exhausted and must have residual pressure or weight. Generally, a residual pressure of no less than 0.1-0.2MP should be retained; If it is an oxygen cylinder used for a long time, it is recommended that the cylinder pressure should not be lower than 0.05Mpa.
3. How to read the oxygen bottle pressure gauge
The pressure gauge of the oxygen bottle indicates the amount of oxygen remaining in the oxygen bottle. The greater the pressure, the greater the oxygen content. When reading, you can know the pressure by looking at the pointer inside: after turning on the main switch of the oxygen bottle, the pointer of the pressure gauge will move clockwise from 0 to a certain position. At this time, the position pointed by the long needle is the current pressure of the oxygen bottle. pressure.
