What maintenance practices are recommended to extend the lifespan of ECAS solenoid valves?

In order to ensure the long-term stable operation of the ECAS solenoid valve and extend its service life, daily maintenance is indispensable. The working status of the solenoid valve and its related components needs to be checked regularly. When checking, focus on whether the air path connection parts are firm and whether there is air leakage between the air pipe and the joint. Aging of the air pipe or loose joints will cause gas leakage, which will affect the performance of the entire air suspension system. After each inspection, it is recommended to re-reinforce all connection points or replace aging parts to maintain the sealing of the system.
Keeping the solenoid valve and its surrounding environment clean is essential for its normal operation. The ECAS system is usually exposed to the bottom of the vehicle or the external environment, and is susceptible to dust, sand and moisture. If these impurities enter the solenoid valve or the air path, it may cause the valve to be inflexible or completely blocked. Therefore, the outside of the solenoid valve should be cleaned regularly, especially after the vehicle is frequently driven in harsh environments (such as muddy or dusty areas). In addition, if necessary, the air path can be disassembled for internal cleaning to ensure unobstructed airflow.
The maintenance of the electrical connection part should not be ignored. It is recommended to regularly check the cables and connectors of the solenoid valve to ensure that they are not worn, loose or corroded due to long-term use. Corrosion may affect the transmission of electrical signals, causing the solenoid valve to fail to respond to the control system's instructions. When cleaning the electrical connections, use a special cleaning agent to remove oxides, and avoid using tools that are too wet to increase the risk of short circuits.
In order to prevent failures caused by aging of components, regular replacement according to the manufacturer's recommendations is also one of the key measures. The seals, filters and other consumable parts in the solenoid valve usually age or deform after long-term use, which will affect the valve's sealing and response speed. Regular replacement of these key components can effectively prevent system performance degradation or even failure.
It is recommended to conduct a comprehensive inspection of the entire ECAS system regularly to detect potential problems in a timely manner. Professional diagnostic tools can be used to detect the operating status of the solenoid valve, such as whether the response speed is within the normal range or whether the air line pressure is maintained at the recommended level. Timely handling of discovered problems can not only avoid greater damage, but also significantly extend the overall service life of the ECAS system and solenoid valve.
