|3 Pneumatic System
In this Automatic Injection Blow Molding Machine, pneumatic system (shown in Fig.7) has been provided for air blowing, air exhausting, and products taking out unit. All the pneumatic drive valves are mounted in the inner frame of the Automatic Injection Blow Molding Machine.
The compressed air with moisture first enters a water segregator to separate the moisture from it. After the water was filtered, the dry compressed air is turned into pressure adjusting valve, the pressure of compressed air in the loop should be regulated as required, the default pressure is 8 bars or so. The oil mist lubricator between the pressure adjusting valve and the loop is used for lubrication of pneumatic components. A small quantity of high quality lubricating oil (about one-third of the cup) should remain in the cup of the oil mist lubricator.
