What are the precautions for regular cleaning of automation pneumatic components

In the field of industrial automation, pneumatic components, as core components, play an indispensable role in improving production efficiency and reducing labor costs. These components are driven by compressed air or gas to achieve various precision automated operations. However, in actual operation, pneumatic components are often invaded by pollutants such as dust, oil, and moisture. If they are not cleaned in time, their performance and service life will inevitably be significantly affected. Therefore, regular cleaning of pneumatic components is a key measure to ensure their stability and reliability.

Preparation before cleaning
Before cleaning pneumatic components, safe operation must be ensured. First, cut off the power supply and release the compressed air in the system to prevent accidents during cleaning. Operators need to wear appropriate protective equipment, including protective glasses, gloves and masks, to prevent chemical cleaning agents or high-pressure gases from causing harm to the body. In addition, it is crucial to choose the appropriate cleaning agent. Non-corrosive cleaning agents should be selected according to the material and degree of contamination of the pneumatic components to avoid damage to the components.

Exterior cleaning
When performing external cleaning, first use a soft cloth or brush to gently wipe away dust and oil on the surface of the pneumatic components. Avoid using metal brushes or hard objects to avoid scratching the component surface. For gaps and connections between pneumatic components, it is recommended to use compressed air or special cleaning tools to clean them to ensure there is no residue. Especially when cleaning electrical components, care should be taken to avoid using too much moisture or chemical cleaners to prevent short circuits or corrosion.

Internal cleaning
The nozzles and filters of pneumatic components are high-risk areas for contamination, so these parts should be disassembled and cleaned regularly to ensure the purity and flow of compressed air or gas. Oil dirt and impurities may accumulate inside the cylinder, affecting the movement efficiency of the piston. When cleaning the inside of the cylinder, it is recommended to use a dedicated cylinder cleaner and strictly follow the manufacturer's cleaning guidelines. In addition, check whether the air path of the pneumatic components is smooth and whether there is air leakage. For blocked air paths, compressed air or special tools need to be used to clean them to ensure smooth air paths.

Post-cleaning treatment
After cleaning, make sure all parts are fully dry to avoid corrosion caused by moisture residue. Then, follow the manufacturer's instructions for reassembly of the pneumatic components. After assembly is complete, be sure to perform functional testing to verify the proper operation of the pneumatic components and ensure there are no abnormal noises or vibrations. In addition, record the date of cleaning, the cleaning agents used and problems found during the cleaning process and other information, and feed it back to relevant personnel for subsequent analysis and improvement.
