Sustainability with strong focus on retrofitting, upgrading and re-use
Rieter’s repair services team helps restore old parts thus improving performance and efficiency of the machines sustainably. At Ramco Group Textile Division (India), Rieter experts identified the following key areas for improvement in compact-spinning machines:
- guiding arm refurbishment,
- ring rail gear box maintenance and
- inverter repair.
After operating for more than 14 years, the pressure hose, top levers and other technological components of the compact-spinning machine showed severe degradation, leading to guiding arm load variation along the machine. As a result, the customer experienced compressed air pressure that was 0.7 bar higher than the specified level of 2.5 bar. Rieter’s repair services team investigated the issue and recommended refurbishing the guiding arm. This refurbishment led to a 28% reduction in compressed air pressure for drafting systems thereby resulting in approximately 0.1 kWh savings per machine. Repairing and replacing worn out and aged parts helped restore the original performance of the drafting system, thus ensuring effective load and consistent drafting and yarn quality.
A clear improvement in terms of load uniformity and performance could be seen after the repair was conducted by Rieter service engineers.
In addition, Ramco Group was experiencing numerous breakdowns on the machine’s inverter. After more than 14 years of continuous operation, inverter breakdowns become more frequent resulting in higher yarn breaks and significant yarn waste. Rieter’s repair services engineers addressed the issue by repairing the inverters and replacing other technology components of the compact-spinning machine. With this Ramco Group was able to increase machine productivity by 10% for yarn counts Ne 60, Ne 80 and Ne 100.
Rieter’s repair solutions, in combination with Rieter OEM spare parts helped Ramco Group reduce their energy consumption by 3 kWh per machine and save raw material by 1.5%. The strong collaboration between Ramco and Rieter repair services resulted in extending the machine lifetime by additional six years. The repairing of the items furthermore reduced electronic waste by 15 000 kg and Rieter ensured the proper recycling of replaced electronical and mechanical parts.
