These gauges are used in a wide range of industrial and medical applications to control the use of oxygen within a usable range. In fact, the installation and use of oxygen pressure gauges has the corresponding skills.
Oxygen pressure gauge installation and use
1、Check carefully before installation whether the parts are fastened,
whether there are traces of damage and destruction in appearance, and all loose
parts should be intact.
2、Connect the oxygen filler with oxygen pressure reducing valve with
oxygen filling conduit and tighten all nuts, do not loose slip.
3, open the oxygen cylinder valve, adjust
the pressure reducing valve, so that the output oxygen pressure table shows
2.8-3.0MPa, at this time the whole gas circuit should be no leakage, otherwise
it should be checked until normal.
4, test oxygen experiment, at this time
should not leak and operate freely, the oxygenator on the pressure gauge should
be consistent with the output table pressure on the pressure reducing valve.
5, open the total valve of the oxygen
cylinder, put the oxygen bomb on the oxygenator positioning seat, align the
oxygen bullet head with the oxygenator gas nozzle, press down the oxygenation
handle, in 2.8-3.0MPa pressure oxygenation 15 to 25s and then slowly release the
handle to remove the oxygen bomb.
The difference between oxygen pressure
gauge and general pressure gauge
The main difference between oxygen pressure
gauge and general pressure gauge is that oxygen gauge is forbidden oil gauge,
that is to say, in the final calibration of the assembly pressure gauge is
through gas or water to calibrate the pressure of the instrument, while the
general pressure gauge is through oil to calibrate, because oxygen can not be
spontaneous combustion but he can help combustion, so to forbid oil.
Structure.
The structure of oxygen pressure gauge and general pressure gauge is basically the same
Function.
Oxygen gauge is to measure the oxygen, the
proportion in the air is expressed in numbers!!!!
General pressure gauge is to measure the
pressure, atmospheric pressure, pipeline (liquid gas) pressure!!!!
The difference: the oxygen meter above the
O2 logo, and the pressure gauge only numbers!!!!
Switching direction.
Oxygen pressure gauge and general pressure gauge switch direction is not the same, oxygen pressure gauge is clockwise direction, while the combustible gas pressure gauge is counterclockwise direction, mainly to prevent misoperation.
Simply put, the oxygen pressure gauge
knowledge an auxiliary tool, basically when leaving the subject, then the value
of this pressure gauge will be completely lost, there is no longer much use.
Similarly, the accuracy of the pressure gauge for our actual work will still
have a relatively large impact
