How to identify illegal operation of overflow dyeing machine

1. Observe the operation status of the equipment
Abnormal noise and vibration
A normally operating overflow dyeing machine usually emits a smooth, regular sound and slight vibration. If you hear abnormal noise, such as sharp friction, impact or roar, and feel obvious strong vibration, it may be a sign of illegal operation.
Abnormal temperature and pressure
Pay close attention to the temperature and pressure display instruments of the overflow dyeing machine. If the temperature is too high or too low, beyond the range required for the normal dyeing process, or the pressure fluctuates abnormally, it may be a manifestation of illegal operation.
Abnormal dye flow
Observe the flow of dye in the equipment. If the dye flow is not smooth, intermittent, too slow or too fast, there may be a problem.
2. Check the operation record and parameter setting
Operation record discrepancy
Check the operation record of the equipment, including the start-up time, dyeing process parameter setting, fabric loading, etc. If it is found that the operation record does not match the actual situation, or there is an incomplete or inaccurate record, there may be illegal operation.
Parameter setting error
Check whether the parameter setting of the overflow dyeing machine is correct. Including parameters such as temperature, pressure, dye flow, time, etc. If the parameter setting exceeds the normal range or does not meet the dyeing process requirements, it may be an illegal operation.
3. Observe the behavior of operators
Untrained employment
Confirm whether the operator has received professional training and has the corresponding operating qualifications. If it is found that untrained personnel are operating the equipment, or the operator is not familiar with the operating procedures and safety precautions of the equipment, illegal operations are likely to occur.
Failure to comply with operating procedures
Observe whether the operator strictly abides by the operating procedures during the operation. For example, whether necessary inspections and preparations are carried out before the equipment is operated, whether the operation is carried out in the prescribed order, and whether the parameters are changed at will during the operation.
If the operator does not wear protective equipment during the operation, leaves the post while the equipment is running, or conducts activities unrelated to the operation, it may also be a manifestation of illegal operation.
4. Compare standard operating procedures with actual conditions
Be familiar with standard operating procedures
Understand the standard operating procedures of overflow dyeing machines, including the specific requirements and precautions for each link of the equipment, such as startup, operation, stop, and maintenance. By comparing with the actual operation situation, illegal operation behaviors can be found.
Regular inspection and evaluation
Regularly inspect and evaluate the operation of the overflow dyeing machine, and compare the actual operation with the standard operating procedures. Inspections can be carried out by on-site observation, checking operation records, and communicating with operators.
Correct and deal with any illegal operation behaviors found in a timely manner, and retrain the operators to ensure the safe and stable operation of the equipment.
In summary, by observing the operating status of the equipment, checking operation records and parameter settings, observing the behavior of operators, and comparing standard operating procedures with actual conditions, the illegal operation behaviors of the overflow dyeing machine can be effectively identified, and timely measures can be taken to correct them to ensure the normal operation of the equipment and production safety.
