The service life of high-speed edgeless twisting machines is affected by equipment brand, maintenance level, and operating conditions. The average service life of standardized models for first tier brands in the industry is 8-12 years, while for second - and third tier brands it is only 3-5 years; If the equipment operates under high load for a long time and is not properly maintained, its lifespan will be directly shortened from 8 years to 5 years, and the maintenance cost will increase by 50% simultaneously.
Core factors affecting service life
Core component wear rate: The spindle speed of high-speed edgeless double twisting machines is generally above 12000 revolutions per minute, and the spindle, dragon belt, and bearing are subjected to high friction for a long time, with a wear rate much higher than that of ordinary double twisting machines. The design service life of spindle bearings usually exceeds 10000 hours.
.Standardization of daily maintenance: Failure to replace spindle oil, clean flying flowers, and inspect gear wear on a regular basis can significantly accelerate component aging. Standardizing maintenance procedures can extend the overall lifespan of equipment by more than 30%.
.Production load intensity: Long term full load 24-hour continuous production and processing of high hardness chemical fiber raw materials will accelerate the loss rate of the transmission system and winding mechanism, further compressing the service life of the equipment.
.Key maintenance points for extending service life
Special maintenance of spindles: replace the 32 # spindle oil every 6 months, monitor the oil level weekly, disassemble and clean the internal cotton wool monthly, which can control the spindle wear within 0.05mm and achieve a stable service life of 8 years.
.Maintenance of transmission system: Apply lithium based grease to the gear meshing area every 3 months, check the tooth thickness with a tooth thickness caliper every 6 months, and replace it in a timely manner when the wear exceeds 0.1mm. This can extend the gear life from 3 years to 5 years.
.Normalized cleaning of the entire machine: Clean the fiber flying flowers in the yarn guide path and winding mechanism after daily production to avoid the accumulation of flying flowers blocking the oil passage and causing electrical short circuits, and reduce unexpected downtime caused by faults.
