The structure of today's twin-screw extruder system varies according to the application field and operating characteristics. It is divided into counter-rotating and co-rotating according to steering, and is divided into meshing type and non-intermeshing type according to the meshing form. Divided into fully engaged and partially engaged. The three-headed forward threaded element has a small cross-sectional area zui, which has a strong shearing effect, but has a low conveying capacity for occasions requiring high shear to ensure longitudinal opening. The twin-screw extruder is easy to operate and maintain, and the compressor is highly automated. The operator does not have to go through long-term professional training to achieve unattended operation. Here are some simple safety repairs introduced by Xiaobian.
1. If the steering fullness of the meter and the pointer is found, check whether the contact of the edge such as the thermocouple is good.
2. After a period of use, perform a comprehensive inspection of the extruder to check the tightness of all screws.
3. After 500 hours of use, there will be iron scraps or other impurities from the gears in the gearbox. Therefore, the gears should be cleaned and the gearbox oil should be replaced at the same time.
4. The multi-phase mixed-feed twin-screw extruder compressor actually has a gap between the tooth faces of the rotor, so it can withstand liquid impact, and can be used to pump liquid gas, dust, and easily polymerized gas.
