The service life of the solenoid valve in the PSA oxygen generator

The PSA oxygen generator belongs to the gas separation equipment, in which the component that controls the airflow in and out is the solenoid valve; it is an important component of the PSA oxygen generator, with the characteristics of compact structure, light weight, low power consumption, high control accuracy, etc., so it is widely used in the PSA oxygen generator.

Structurally, the solenoid valve consists of a cylinder, a valve, and a drive device; by constantly opening and closing, it controls the in and out and flow direction of the gas, so that the entire oxygen production process can proceed smoothly. The reason why the solenoid valve is important is that the quality and reliability of the solenoid valve will directly affect the operating efficiency of the oxygen production equipment. Therefore, when selecting the solenoid valve, the manufacturer will conduct strict testing and quality control on it to ensure that the quality and performance are reliable.

Under normal circumstances, the solenoid valve can perform tens of thousands of switching operations and has a lifespan of about 5 years. However, in actual production, the solenoid valve is often adversely affected by the use conditions, workload, use environment, etc., so the actual service life will vary. Specifically, the following factors are included;

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

• Ambient temperature: When the working environment temperature is too high or too low, it may affect the internal components and sealing rings of the solenoid valve, resulting in the failure of the solenoid valve.

• Oil pollution: The solenoid valve in the PSA oxygen generator usually needs to be lubricated with lubricating oil. If the lubricating oil is contaminated or used improperly, the life of the solenoid valve may be reduced.

• Frequent shutdown and start-up: The PSA oxygen generator is often in a shutdown and start-up state, which will shorten the service life of the solenoid valve.

When the above unfavorable factors cannot be avoided, the service life of the solenoid valve can only be extended by regular maintenance and care, such as regular cleaning and lubrication of the solenoid valve. In addition, pay attention to and replace the faulty solenoid valve in time to ensure the normal and efficient operation of the entire system. If more specific information is required, it is recommended to refer to the product manual and maintenance manual provided by the manufacturer.
