PSA oxygen concentrator belongs to gas separation equipment, in which the component that controls the airflow in and out is an electromagnetic valve; It is an important component of PSA oxygen concentrators, characterized by compact structure, light weight, low power consumption, and high control accuracy. Therefore, it is widely used in PSA oxygen concentrators.

Structurally, electromagnetic valves are composed of cylinders, valves, and driving devices; By continuously opening and closing, controlling the inlet and outlet and flow direction of gas, the entire oxygen production process can proceed smoothly. The reason why electromagnetic valves are important is because the quality and reliability of electromagnetic valves directly affect the operational efficiency of oxygen production equipment. Therefore, when selecting solenoid valves, manufacturers will strictly test and control their quality to ensure reliable quality and performance.

In general, solenoid valves can perform tens of thousands of switching operations with a lifespan of around 5 years. However, in actual production, electromagnetic valves are often affected by adverse factors such as usage conditions, workload, and usage environment, so their actual service life may vary. Specifically, it includes the following factors;

Working load: When the solenoid valve is in a high load state for a long time, such as frequent switching, high-frequency operation, etc., it will lead to a shortened service life of the solenoid valve.

Environmental temperature: When the working environment temperature is too high or too low, it may have an impact on the internal components and sealing rings of the solenoid valve, leading to the failure of the solenoid valve.

Oil pollution: The solenoid valves in PSA oxygen concentrators usually require lubrication with lubricating oil. If the lubricating oil is contaminated or improperly used, it may reduce the lifespan of the solenoid valves.

Frequent shutdown and startup: The PSA oxygen concentrator is often in a shutdown and startup state, which can shorten the service life of the solenoid valve.

When the aforementioned adverse factors cannot be avoided, regular maintenance and upkeep can only be relied on to extend the service life of the solenoid valve, such as regular cleaning and lubrication of the solenoid valve. In addition, it is also necessary to pay attention to and replace faulty solenoid valves in a timely manner to ensure the normal and efficient operation of the entire system. If more specific information is needed, it is recommended to refer to the product manual and maintenance manual provided by the manufacturer.
