压力表、氧气表两用校验器上有两级隔离器,采用油水隔离的方法检定氧气表。使用时要消耗水量。为避免油进入第二级隔离器内,需要经常观察油杯中油位的高度,并根据油位的下降来判断水的消耗量,以便随时补入清水。加水方法,一般使用金属注射器从氧气表接头处注入。由于金属注射器与氧气表接头无法配合,加水时水经常从接头处溢出,很不方便。为此我制作了一个注水接头,配合金属注射器使用,效果良好。
Pressure gauge, oxygen meter dual checker with two isolators, the use of oil and water isolation test oxygen meter. Use to consume water. In order to avoid the oil entering the second stage isolator, it is necessary to constantly observe the oil level in the oil cup, and determine the water consumption according to the drop of the oil level so as to fill in the fresh water at any time. Water method, the general use of metal syringe injection from the oxygen meter joints. Due to the incompatibility between the metal syringe and the oxygen meter connector, water often overflows from the connector when water is added, which is very inconvenient. To this end I made a water connector, with the use of metal syringes, the effect is good.
