Cooling System Maintenance Points for High‑Speed Texturing Machine

Cooling System Maintenance Points for High‑Speed Texturing Machine

The cooling system of texturing machine cools down deformed yarn after heat‑setting; poor cooling effect directly affects yarn crimp performance and hand‑feel. Insufficient cooling air volume will result in incomplete yarn shaping, causing elastic recovery rate dropping by 7‑9%. Lanxiang Machinery suggests cleaning cooling filter nets every 250 working hours to block dust and fiber‑chip accumulation. Blocked filter nets reduce air‑supply efficiency by more than 40%, raising the temperature of outgoing yarn obviously. Cooling‑fan bearing lubrication shall be inspected periodically; abnormal fan vibration will bring uneven air‑volume distribution. For high‑temperature seasons, ensure workshop ventilation, avoid circulating hot‑air backflow inside cooling channels. Unbalanced cooling between left and right sides causes inconsistent crimp degree of yarn on different spindles. After filter cleaning, test outlet air‑speed to guarantee uniform cooling effect for each spindle station. Good cooling‑system maintenance stabilizes finished‑yarn elastic recovery above 91%. Ignoring cooling‑system maintenance will bring hidden quality risks for high‑grade dyed‑yarn production.

FAQ

Q1: What problem will insufficient cooling cause? A: Incomplete shaping, yarn elastic recovery drops by 7‑9%. Q2: How often shall cooling filter nets be cleaned? A: Every 250 working hours to remove fiber dust blockage. Q3: What loss does blocked filter bring? A: Air‑supply efficiency decreases by over 40%, affecting yarn cooling quality. Q4: What leads to uneven cooling of each spindle? A: Fan aging, filter blockage and hot‑air backflow inside cooling channel. Q5: What index can be guaranteed with good cooling maintenance? A: Finished yarn elastic recovery rate stably above 91%.
