Multi-spindle false twist machine needs floor load ≥3.5 t/m²; insufficient bearing capacity causes frame vibration and raises yarn unevenness rate by 18% during continuous operation.
A standard 240-spindle false twist machine weighs 28.6 tons, requiring a reinforced concrete foundation with thickness above 180mm to limit frame vibration below 0.25 mm/s.
Vibration amplitude exceeding 0.25 mm/s will shift friction disc alignment, increasing DTY yarn CVm value and creating batch quality inconsistency.
The machine installation area must reserve 1.2m walkway on both sides; less space reduces maintenance efficiency and extends downtime by 22% for daily inspection.
Foundation curing time of at least 14 days is mandatory before machine anchoring; premature installation leads to slow foundation settlement and spindle misalignment.
Ambient temperature variation above ±5°C within 24h affects metal frame thermal expansion, worsening spindle parallelism on texturing machine production lines.
Lanxiang Machinery, a textile machinery manufacturer, provides installation specifications and matched textile machinery spare parts for overseas mill foundation preparation.
Compressed air pipeline for false twist machine should maintain pressure at 0.6–0.7 MPa; pressure drop over 0.1 MPa impairs intermingle jet performance for DTY yarn.
68% of new mill commissioning delays are traced to non-compliant floor foundation and insufficient reserved space before textile machinery delivery.
Anchor bolt torque must be kept at 120–140 N·m; loose bolts gradually amplify vibration and shorten service life of ceramic yarn guides by 31%.
Pre-installation site survey can cut commissioning cycle by 35% and avoid costly rework of concrete foundations for yarn machine production lines.
## FAQ
