PENGOPTIMALAN PROSES BALANCING PADA BLADE INDUCED DRAFT (ID) FAN(Studi Kasus ID Fan Pabrik Indarung V PT Semen Padang)

Abstract

ABSTRACT

In the prevalent industrial machines with rotary motion (rotating machinery). Each of the machines rotating movement will always experience vibration. ID fan is one example of a rotating machine movement. Vibration is always associated with unbalance. ID fan serves to suck the hot air from the cooler grid is then compressed to heat the raw material mix before entering into high kitchen (kiln). Because the air is sucked by the ID fan mixes with the common attachment material (coating) on the fan impeller ID. The impact of the resulting unbalance attachment and high vibration on the impeller bearing. This study aimed to find a way to manually balance the weight determination which does not require the operation of the equipment so that the risk of error correction mass (mass trial) to ensure the equipment is very small and the method used can be applied in any balancing process. The method used in this study is the method of balancing Static and Dynamic balancing. Based on the results of research conducted on balancing the ID fan speed measurement data obtained in the form of graphs and time waveform measurements were performed radial direction (horizontal and vertical) and the axial direction. Initial vibration on the fan ID is 6.91 mm / s in the direction of the horizontal bearing 2. After static balancing method and followed the method of dynamic balancing of vibration can be reduced to 2.60 mm / s. From these data the vibrations can be categorized into normal vibrations in accordance with ISO 10816-3 (Mobius Institute. 2005) is in Zone B (Unrestricted Long Term Operation). After balancing the balancer weight gain (mass) on each impeller are obtained center of gravity closer to the point of rotation.
