Abstract

Sistem pelumasan merupakan sebuah sistem yang sangat penting dalam menjaga keandalan gearbox main lube oil pump. Fungsinya tidak hanya untuk pelumasan kerja saja, tetapi untuk memindahkan kotoran dan mendinginkan bantalan turbin. Dalam penelitian ini objek yang digunakan adalah Gearbox main lube oil pump PLTGU unit 1.3 pada di PT. PJB UP GRESIK., penelitian dimulai dengan observasi data dan studi beberapa literature terkait, dilanjutkan dengan mentoring bersama teknisi predictive maintenance, kemudian dilakukan pengambilan gambar actual serta data oil used analysis sesuai dengan SOP (Standard Operational Procedure). Pengambilan data dilakukan dengan menggunakan metode oil sampling. Setelah dilakukan pengambilan data maka dilakukan analisa dari data oil used analysis yang didapat berdasarkan standart EPRI (Electric Power Research Institute). Dari hasil penelitian didapatkan bahwa kerusakan gearbox main lube oil pump diakibatkan oleh adanya kerusakan pada gears 4 dan 5 yang mengalami keausan dan patah secara bertahap sehingga mengakibatkan menurunnya efisiensi pada kinerja geabox. Setelah dilakukan perawatan dengan penggantian part gears 4 dan 5 pada gearbox ,uji karakteristik menunjukkan pada kondisi normal dengan ferrous index adalah 73,6 menurun menjadi 0.0 serta nilai kontaminasi yang sebelumnya high fault yaitu 21 turun menjadi normal yaitu 14 "=============================================================================================" Lubrication system is a system that is very important in maintaining the reliability of the main gearbox lube oil pump. Lubrication function is not only to work, but to remove dirt and cool the turbine bearings. In this study the object used is the main gearbox lube oil pump unit PLTGU 1.3 at PT. PJB UP Gresik., The study began with the observation data and studies some related literature, followed by a joint mentoring predictive maintenance technician, then do the actual shooting as well as data analysis of used oil in accordance with SOP (Standard Operating Procedure). Data were collected using sampling oil. After data collection, the analysis of the data analysis of used oil obtained by standard EPRI (Electric Power Research Institute). The result showed that the damage to the main gearbox lube oil pump caused by the damage to the gears 4 and 5 are experiencing gradual wear and fracture which resulted in a decreased efficiency in the performance of geabox. After treatment with replacement parts gears 4 and 5 on the gearbox, the test showed the characteristics under normal conditions with ferrous index was 73.6 decreased to 0.0 and the value of the previously high contamination fault is 21 drops to normal is 14.
