Inspection and treatment methods: (1) First observe whether the float and the inner tube of the oxygen flow meters are blocked at the gas outlet. The float of the flow regulating valve does not move.
Replace the original display tube with the same model.Ģ. This situation is mostly caused by the mismatch in the geometry of the cone surface of the replacement display tube after the display tube ruptures. The general reasons for this situation are: (1) the front end of the flow adjustment rod is poorly sealed, which is caused by the wear or aging of the seal ring for a long time, as long as the seal ring of the same type is replaced, the fault can be eliminated (2) The glass display tube is not suitable. Turn the flow adjustment knob, the float changes not linearly but suddenly increases or decreases. The pressure action changes from the original high-pressure oxygen to low-pressure oxygen, and after the flow is regulated by the oxygen flow meters, it can be output by the output nozzle at a constant flow value.ġ. The working principle is that the oxygen in the bottle (oxygen source) is reduced by the pressure reducer. The other is an oxygen meter with a flow meter humidifier bottle. One type of oxygen flow meter is an oxygen meter decompressor and a flow meter humidifier bottle. The main structure is composed of two parts: flow regulator and pressure reducer.Īt present, there are two main ways for the hospital to provide oxygen: one is oxygen flowmeter regulator, one is the wall pipe oxygen supply. Oxygen flow meters are mainly used in medical units for oxygen inhalation for patients. Failure analysis and solution of oxygen flow meter 2020 / 02 / 20
