PERENCANAAN SISTEM PERAWATAN MESIN DUST COLLECTOR PECS ID FAN MENGGUNAKAN METODE RELIABILITY CENTERED MAINTENANCE

Dust Collector PECS ID Fan adalah fasilitas penyaring debu yang berfungsi sebagai penampung serta penyaring debu dan uap panas yang dihasilkan dari proses pembakaran produk kokas batubara. Kerusakan PECS ID Fan dapat menyebabkan mesin trip, temperatur bearing tinggi dan terjadi kebocoran media filter pada unit Dust Collector. Penelitian ini bertujuan mengetahui penyebab abnormal operation dan merancang sistem perawatan pada mesin PECS ID Fan. Penelitian ini menggunakan tahapan Reliability Centered Maintenance untuk mendapatkan model perawatan yang efektif pada PECS ID Fan. Hasil penelitian menunjukkan penyebab abnormal operation disebabkan kurangnya penerapan perawatan yang terencana. Sistem perawatan dengan menggunakan Reliability Centered Maintenance memperoleh hasil perawatan pada komponen Chamber (Cage dan Membrane Filter), Air Compressor (Pulsing Pipe) dan Cyclone Dust (Venturi Valve) mengimplementasikan tindakan Failure Finding (FF), komponen ID Fan (Motor, Coupling, Impeller dan Bearing) menerapkan tindakan Condition Direct (CD) dan sub-komponen Screw dari komponen Rotary Lock menerapkan tindakan perawatan Time Directed (TD). Reliability Centered Maintenance dapat mampu merencanakan sistem perawatan komponen peralatan berdasarkan tingkat kerusakan dan pengaruh terhadap operasi.

Over time, performance of tubular backpulse pressure filters in kraft mills deteriorates, even with regular acid washing. Unscheduled filter replacement due to filter plugging results in significant costs and may result in mill downtime. We identified acid-insoluble filter-plugging materials by scanning electron microscope/energy-dispersion X-ray spectroscopy (SEM/EDS) and X-ray diffraction (XRD) analysis in both polypropylene and Gore-Tex™ membrane filter socks. The major filter-plugging components were calcium sulfate (gypsum), calcium phosphate (hydroxylapatite), aluminosilicate clays, metal sulfides, and carbon. We carried out detailed sample analysis of both the standard acid-washing procedure and a modified procedure. Filter plugging by gypsum and metal sulfides appeared to occur because of the acid-washing procedure. Gypsum formation on the filter resulted from significant hydrolysis of sulfamic acid solution at temperatures greater than 130°F. Modification of the acid-washing procedure greatly reduced the amount of gypsum and addition of a surfactant to the acid reduced wash time and mobilized some of the carbon from the filter. With surfactant, acid washing was 95% complete after 40 min.
