Operating Instruction of Pipelines for MY-120/14D Extruder

The piping systems for Muyang-MY120×2/14DTwin-Screw Extruder are divided into two parts, namely water piping and steam piping. The important parts and components in the whole systems are adopted imported products, which are adjusted and controlled by PLC systems. We hope that the customers can read the Operation Manual carefully and then correctly operate and use the equipment, so as to ensure the safety in production; otherwise, the customers should be responsible for any consequence resulted.



Operating instruction:

1. It is required to provide clean tap water for the water box;
2. It is required to provide dry and filtered compressed air with a stable pressure of 0.5 MP for the adjusting valve;
3. First turn on the bypass when trying out the water piping for extruding chamber and conditioner, namely turn on all valves in the water piping (close the ball valves at both sides of the flow meter and adjusting valve);
4. After the water pump is started, adjust t he pressure of pressure reducing valve, so as to make the reading on the manometer is stabilized at a certain value between 0.4~0.6 MP after the pressure is reduced;
5. Close the bypass on the feed extruder, turn on the ball valves at both sides of the flow meter and adjusting valve, so as to allow water pass through the flow meter and adjusting valve, and then carry out adjustment on the operating screen;
6. In normal case, the water in conditioner is sprayed out stably; otherwise, it is necessary to check whether t he pipeline is blocked or not;
7. According to water quality, the filter shall be opened once a month or half a month, to remove impurities from the filter screen;
8. In case of normal work, the brass stop valve is normally opened, while the stop valve at the side of main part of extruder shall be opened each time when the machine is shut down.
