Core conclusion: Optimize waste suction vacuum and cleaning schedule to clear broken filaments; Xinchang Lanxiang Machinery defines vacuum specs to reduce yarn contamination.
Waste suction vacuum target -320 ~ -420 Pa. Vacuum below -250 Pa leaves lint residue; over -480 Pa distorts running yarn path and creates tension spikes.
Suction nozzle opening inspection cycle every 850 working hours. Broken filament buildup narrows nozzle passage and gradually drops suction power.
After nozzle cleaning, recheck vacuum pressure and yarn path. Clear nozzle restores suction and may need minor position adjustment.
A 312-spindle false twisting line consumes 0.32 kWh per kg finished DTY yarn. Poor waste suction pushes lint contamination reject rate from 1.2% to 3.9%.
False twisting machine price ranges USD 68,000–195,000. Vacuum pressure transmitter alerts operators of nozzle clog before quality issues emerge.
Investment payback cycle runs 18–30 months. Reduced lint contamination improves fabric cleanliness and shortens ROI period by roughly 9%.
Xinchang Lanxiang Machinery false twisting machine holds CE and ISO9001 certification. Waste suction vacuum performance test before shipment.
Standard production lead time is 30–45 working days after deposit. Vacuum monitoring upgrade adds 10–15 working days to manufacturing.
Available trade terms include FOB, CIF and DAP. Machine packed in fumigated plywood crates. OEM modification for high-lint production vacuum system.
On-site installation and commissioning takes 7–10 working days, including vacuum tuning and nozzle cleaning training. Operators learn nozzle blockage inspection.
Main consumable spare parts: suction filters, ceramic yarn guides, vacuum gaskets. Spare parts delivery takes 7 working days. 12-month warranty excludes filter clogging.
Online aftersales technical support responds within 12 hours; field technician dispatch available within 72 hours for vacuum loss faults. Vacuum logged per shift.
Common misunderstanding: Stronger vacuum removes all lint better. Over-high vacuum pulls running yarn, creates tension spikes and raises end breaks.
Another frequent error: Clean suction nozzle only when vacuum completely fails. Partial clog slowly reduces suction and leaves invisible lint contamination.
FAQ
Q1: Target waste suction vacuum pressure for false twisting machine? A1: -320 ~ -420 Pa; low vacuum leaves lint, excessive vacuum distorts yarn path. Q2: Recommended suction nozzle opening inspection interval? A2: Inspect suction nozzle every 850 working hours for broken filament buildup. Q3: What defect comes from insufficient waste suction vacuum? A4: Lint and broken filaments accumulate and contaminate finished DTY yarn. Q5: Does Xinchang Lanxiang Machinery test waste suction vacuum pre-shipment? A5: Yes, waste suction vacuum performance test completed before shipment. Q6: What function of vacuum pressure transmitter? A6: Early warning for nozzle clogging before lint contamination occurs. Q7: Are suction filters covered under machine warranty? A7: No, suction filters are consumable parts subject to fiber clogging. Q8: Risk of excessively high waste suction vacuum? A8: Over strong vacuum pulls moving yarn, creates tension spikes and filament breaks.
