20.500.12556/RUL-154504 An energy-efficient vacuum system as an alternative to the inefficient use of compressed air for the yarn suction gun The yarn suction gun (YSG) is used to draw the running yarn in the initial phase and when changing the bobbin in a continuous yarn production and is usually operated with compressed air. With a typical overall efficiency of compressed air generation, treatment and delivery, the electrical power requirement increases to over 75 kW just to operate a single YSG. Such high electrical power consumption must be addressed. One of the most effective ways to reduce the cost of compressed air generation and treatment is to replace the existing technology with one that is less energy intensive. Based on centrifugal blowers used in vacuum cleaners, a prototype was built and connected to various mixing chambers. Simulations and measurements were performed to evaluate the tension force acting on the yarn. Research on the use of vacuum for yarn suction is presented. It is estimated that after optimizing the suction by using vacuum, only 20 kW of electrical power will be required for one YSG, halving the cost of the current approach using compressed air generation. vacuum suction supersonic vacuum flow energy efficiency yarn suction gun vakuumsko sesanje nadzvočno polnjenje vakuuma energijski izkoristek pištola za sesanje filamentov true false true Angleški jezik Slovenski jezik Članek v reviji 2024-02-19 10:33:11 2024-02-19 10:33:15 2025-02-11 13:12:02 0000-00-00 00:00:00 2024 0 0 Str. 460-470 iss. 3 Vol. 115 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.521 1754-2340 10.1080/00405000.2023.2195978 148150787 Prezelj_..._An_energy-efficient_vacuum_system_as_an_alternative_to_the_inefficient_use_of_compressed_air_for_the_yarn_suction_gun.pdf Prezelj_..._An_energy-efficient_vacuum_system_as_an_alternative_to_the_inefficient_use_of_compressed_air_for_the_yarn_suction_gun.pdf 1 105BFA210859C49ACDBFFB9B27CA2DBB 224d2ea58538ff7787ef0149e600b3caf1bccebd9a373483c831afdccbd5381a 65dd5b58-cf0a-11ee-9559-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180969 https://www.tandfonline.com/doi/full/10.1080/00405000.2023.2195978 1 e8d03ecc-cf09-11ee-9559-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180968 Fakulteta za strojništvo 0 0 0
