Kumaş Polisaj Tezgâhında Gürültü ve Titreşim Azaltım Çalışması

Sanayileşme ile artan gürültü seviyeleri insan sağlığını olumsuz etkilemektedir. Özellikle yüksek gürültülü işyerlerinde çalışanların yüksek gürültüye maruz kalması işçi sağlığını olumsuz etkilemektedir. Bu çalışmada, bir tekstil firmasında dokuma tezgahı türü olarak kullanılan kumaş polisaj tezgahının gürültü ve titreşim problemini azaltmak için bir dizi çalışmalar yapılmıştır. Çalışanların gürültüye maruz kaldıkları çalışma alanında bulunan tezgahlardan kumaş polisaj makinesi, pilot çalışma tezgahı olarak seçildi. Polisaj tezgahı ve çevresinin bazı noktalarından gürültü ve titreşim ölçümleri alınmıştır. Alınan titreşim ve gürültü ölçümleri analiz edilerek polisaj tezgahının gürültü ve titreşim seviyeleri ve karakteristikleri belirlendi. Makinenin gürültü emisyonlarını azaltmak için çeşitli gürültü ve titreşim izolasyon uygulamaları yapılmıştır. Ofis çalışma alanına gürültü iletimini azaltmak için ofisler ile kumaş işleme alanı arasına gürültü duvarı kuruldu. Fan kanalları ise ses yalıtım malzemeleri ile kaplanmıştır. Titreşim kaynaklı gürültüyü azaltmak için tezgah ayaklarının altına titreşim izolasyonlu kauçuk takozlar yerleştirilmiştir. Aynı koşullarda tekrarlanan ölçüm ve analizler sonrasında, polisaj makinesinin gürültü ve titreşim seviyelerinin önemli ölçüde azaldığı görülmüştür.

Noise and Vibration Abatement Study on a Fabric Polishing Machine

Increasing noise levels with industrialization adversely affect human health. Especially in high noisy workplaces, the exposure of workers to high noise negatively affects workers' health. In this study, a series of studies have been carried out to reduce the noise and vibration problem of a polishing bench, which is a type of weaving loom in a textile company. A fabric polishing bench in the working area where workers are exposed to its loud noise was chosen as the pilot fabric machine. Noise and vibration measurements were taken from some points of the polishing bench and its surroundings. By analyzing the vibration and noise measurements taken, the noise and vibration levels and characteristics of the polishing bench were determined. Some noise and vibration isolation applications have been implemented to reduce the noise emission of the bench. In order to reduce noise transmission to the office workplace, a noise wall was set up between offices and the fabric processing area. The fan ducts were covered with sound insulation materials. For reducing vibration-induced noise, vibration isolation rubber pads are placed under the bench legs. After repeated measurements and analyzes under the same conditions, it was observed that the noise and vibration levels of the polishing bench were significantly reduced.
