Hydraulic oil filtration on barbot pumps


The main problems encountered were leaks, due to wear caused by contaminants and excess particulates, which cause problems in the gear pump, valves, seal ring assemblies, cylinder liner and filter clogging.

Due to the need of companies to reduce expenses and increase diesel production machine productivity, the study is based on analyzing the effectiveness of the use of filter pumps to improve the useful life of parts, components and hydraulic fluids of application in industrial slip pumps. Samples of the hydraulic oil used in the process were collected, studied and analyzed in order to demonstrate the cost benefit of the application of filter pumps. Through the experiments performed comparative analyzes were performed between the lubricants without the filtration and with the application of the filtration process, observing the results showed the efficiency of the applied process. Based on the studies carried out, the advantages of hydraulic oil filtration in slip pumps were evident, as it allowed a longer time for equipment operation, reduced downtime, reduced maintenance costs and reduced environmental impact. The methods used to improve the system consisted of the filtration of the oil, using a filter pump to retain the wastes that contaminate the hydraulic system, thus reducing the maintenance time and stops of the atomizers, increasing the mass production. The results obtained demonstrate that the filtration did not completely eliminate the contaminations but reduced significantly. The company spends about R$ 12.040,00 (twelve thousand and forty reais) per year for the recovery of each slip pump, with 14 pumps in total. However, by filtering, this value could be reduced, because the contaminants contained in the lubricating oil showed a reduction of 82%, increasing the useful life of the oil and equipment. The main problems encountered were leaks, due to wear caused by contaminants and excess particulates, which cause problems in the gear pump, valves, seal ring assemblies, cylinder liner and filter clogging.
