1）What is the most effective way to reduce spinning costs?
Answer: Raw materials, labor, and energy consumption are the main factor?to?control of spinning costs.
- Reasonable cotton blending is the first hurdle in cost control, and selecting raw materials according to customer requirements is the primary task in cost reduction.
- Reasonably adjust the spinning process, while meeting the requirements of yarn quality, and control the cotton drop during cleaning, carding, and combing.
- Reduce production waste and improve production efficiency.
- Strictly control labor employment, adopt mature automation equipment, and reduce labor.
- Improve employee operational skills and increase grandstand capacity.
- Adopt Advanced and mature energy-saving equipment to reduce energy consumption. Variable frequency control should be used for air conditioning fans and water pumps.
- Improving equipment capacity is also an effective way to reduce energy consumption per unit of product.
- The front spinning adopts a large quantity and the coarse yarn has a high twist; Fine yarn uses small spindle diameter spindles and spindle wharve.
2） How to prevent the phenomenon of people leaving the workshop without turning off the lighting?
Answer: Management is inspection, and inspection should be implemented in assessment
- Establish systems and standardize assessments.
- Arrange a duty roster, with someone responsible for checking and implementing responsibilities every day.
- Each shift duty personnel shall inspect and assess.
- Training and learning will be emphasized repeatedly before and after work to strengthen employees’ awareness of energy conservation.
- A combination of voice control or timed switches can be used.
3- There is a lot of noise during equipment operation. What are the effective methods to check the leakage points of compressed air?
Answer: The most effective method is still parking inspection. For example, during National Day or Spring Festival holidays, the sound of air leakage points is very clear. If there is no time to park,? soap water or detergent can be applied to the possible leak points. If there is a phenomenon of blowing bubbles, it is a leak point. Yhere is a large amount of air leakage, to fell by hand.
The frequency converter has power supply, but the display is not showing, usually due to an internal problem with the frequency converter?
Answer: There are roughly three possible projects:
- If the indicator light of the frequency converter is on, it means there is a fault in the switch power supply part;
- ?If the indicator light is not on, check the power input part;
- Another issue is poor contact or malfunction of the frequency converter display panel.
Will adding a frequency converter to the fine yarn motor save electricity?
- After installing a frequency converter on the fine yarn, it is convenient to control the motor to run at multiple speeds, which improves quality, reduces breakage, increases unit production capacity, and reduces unit energy consumption.
- Adjusting the spindle speed of the spinning machine does not require replacing the pulley, greatly reducing the workload of maintenance workers.
- Reduce the consumption of pulleys, belts, and other accessories.
- At present, frequency converters are basically standard on fine yarn machines.
- The more advanced spinning machines are multi motor drives, with independent drives for stretching, twisting, winding, and forming.
