Pneumatic triplets need to be refueled.

　　The function of the oil mist precision guide rod cylinder in the pneumatic triplet is to refuel, to lubricate the cylinder actuator, the control element is generally a solenoid valve, which is suitable for the positioner. The specification stipulates that the oil content of the instrument gas should be less than 10mg / m3, which is a general quality requirement for instrument air requires special treatment for different actuators.

　　Pneumatic triple oil feeder uses JIS K2213 oil (ISO Vg32 similar oil). Do fill more than one eighth of the cup. The number 0 is the minimum amount of oil 9 is the top value of the oil amount. It cannot be rotated the 9-0 position must be rotated clockwise.

　The pneumatic triple unit is composed of three parts: a precision guide rod cylinder filter, a pressure reducing valve an oil mist device. The filter is mainly responsible for filtering impurities in the compressed air, the pressure reducing valve is mainly responsible for controlling the system pressure, the oil mist device is responsible for the back end components Oil lubrication. However, now that many products can be lubricated without oil, the frequency of use of the triple-part lubricator is getting lower lower. Now the lubricator is configured mainly for the purpose of replacing the lubricating grease after a few years. Lubricate the oil.  now the filter pressure reducing valve can be integrated into a filter pressure reducing valve, the structure is also optimized. Therefore, the current triplets are no longer traditional triplets. Generally, it is a modular air source treatment element, there are many configurations that can be selected combined as needed.
