Abstract
PT.Pupuk kujang is a company engaged in the field of petrochemicals, with the processing of certain raw materials into basic materials required in the manufacture of fertilizers, especially urea and other chemicals, as well as the basic material processing into various types of fertilizers and materials results other chemicals, in the production of fertilizer is often under constraints on the production machine, such as centrifugal pumps overhang W-GA 1033A which are in the company PT.Pupuk kujang. Centrifugal pumps included into the dynamic type pump impeller pump which has the functions convert mechanical energy into energy from the pump speed. In operation of centrifugal pumps overhang W-GA 1033A often suffer damage to its components, component damage that often occurs in centrifugal pumps overhang WGA 1033A is bearing components, bearing that is used is the type of deep groove ball bearing. According to visual inspection of bearing damage that occurs in centrifugal pumps W-GA 1033A overhang caused by wear and tear gland packing which resulted into a leaking pump, and the water leaked into the bearing housing and cause the bearing to be damaged. According to historical data residing in PT Pupuk Kujang Cikampek damage to the components bearing centrifugal pump overhang W-GA 1033A occurred on 30 June 2014. To determine the level of vibrations that occur in centrifugal pumps overhang W-GA 1033A conducted to collect data by using a measuring instrument Machinery Health Analyzer at points A, B (electric motor), C, D (pump) with the vertical direction, horizontal and axial. After that the measurement data is transferred to a computer for analysis using software which will generate data in the form of spectrum. Where on the spectrum there is the output of a number of them: overall = 13.55 PEAK = 9.6 RMS, frequency = 58.75 CPM to the high velocity of 6 mm / s and is based on the condition of the pump spectrum in danger (that are in the red zone) as seen in table severity charts ISO 10816-3. To find out the defects that occur in the bearing calculation frequency bearing element which is obtained: BPFI = 298.1 Hz, BPFO = 192.9 Hz, BSF = 10.71 Hz, FTF = 19.3 Hz. Once it is done bearing design calculations to compare the age of bearing on the calculation and the actual bearing age. Where the calculation results obtained bearing age = 24383.5 million operations and actual bearing age = 3600 hours of operation. This occurs due to the increase in vibration that occurs in centrifugal pump caused by local problems (problems at the pump component) that the packing gland component experiencing wear and tear that causes the bearing to be damaged
