The fault manifestations of the one-step false twisting machine mainly include:
1. Abnormal hot box temperature: The hot box temperature of the false twisting machine may excessively rise, not rise, or have unstable temperature levels. These abnormalities may be caused by damage to the heating elements of the hot box, malfunctions in the heating control system, or poor heat conduction, and require timely repair.
2. Abnormal winding tension: The winding tension of the false twisting machine may be too high or too low. Excessive tension may cause double twist yarn to deform during compression, while insufficient tension may cause yarn to loosen and affect product quality.
3. Abnormal winding speed: The winding speed of the false twisting machine may be too fast or too slow. Too fast speed may cause yarn breakage, while too slow speed may lead to low production efficiency.
4. Abnormal yarn quality: The yarn produced by the false twisting machine may have quality problems, such as yarn breakage, excessive fuzz, and uneven twist. These issues may be caused by malfunctions in the false twister, roller wear, yarn quality issues, and other reasons.
5. Equipment shutdown failure: False twisting machines may experience equipment shutdown failures, such as overheating, power failure, control system failure, etc. These faults may be caused by equipment aging, improper maintenance, environmental factors, and other reasons.
The above are common faults of one-step false twisting machines. If these problems occur, timely troubleshooting and repair are needed to ensure the normal operation of the equipment and product quality.
