和一般压力表的区别我们从它的应用范围、结构、作用和开关方向来进行分析。 The difference between an oxygen pressure gauge and a general pressure gauge is analyzed from its application scope, structure, function and switching direction.
The main difference between an oxygen pressure gauge and a general pressure gauge is that the oxygen gauge is an oil-free gauge, that is, the final calibration of the assembled pressure gauge is to verify the instrument pressure by gas or water, and the ordinary pressure gauge is oil. check,
Because oxygen can't ignite spontaneously, but he can fuel all the oils to be banned.
和一般压力表的构造是基本一致的。 The structure of the oxygen pressure gauge and the general pressure gauge are basically the same.
The oxygen meter measures oxygen, and the proportion in the air is expressed by numbers! !! !!
General pressure gauges measure pressure, atmospheric pressure, and pressure inside the pipeline (liquid gas)! !! !!
Difference: The oxygen meter has a 02 sign on it, while the pressure gauge only has numbers! !!
和一般压力表的开关方向不一样，氧气压力表是顺时针方向，而可燃气体压力表是逆时针方向，主要是防止误操作。 The switching direction of the oxygen pressure gauge is not the same as the general pressure gauge. The oxygen pressure gauge is clockwise, while the flammable gas pressure gauge is counterclockwise, which is mainly to prevent misoperation.
