What oil is needed for lubricating the three-piece unit?
1 Answers
For the pneumatic three-piece lubricator, use JIS-K2213 transmission oil (ISO-Vg32 or equivalent). Below is relevant information about the pneumatic three-piece unit: 1. Introduction: In pneumatic technology, the combination of an air filter, pressure reducing valve, and lubricator into one unit is called a pneumatic three-piece unit. It is used to purify and filter the air source entering pneumatic instruments and reduce the pressure to the rated supply pressure for the instruments, functioning similarly to a power transformer in an electrical circuit. 2. Features: The pressure reducing valve stabilizes the air source, keeping it in a constant state, which reduces damage to valves or actuators caused by sudden changes in air pressure. The filter cleans the air source by removing moisture from the compressed air, preventing moisture from entering the device with the gas. The lubricator lubricates moving parts of the mechanism, including components that are difficult to lubricate, significantly extending the service life of the mechanism.
