Industrial Purity of Working Fluid in Machine Lubrication Circulation Systems
Lubricants represent the most important element of mating friction couples, largely determining their reliability and service life. Contamination of the working fluid poses a serious threat to the performance and reliability of the equipment. Mineral or synthetic oil is the most common working fluid in lubrication systems. Cleaning, cooling, and maintaining the required pressure of the working oil are decisive factors for reliable operation of mating friction couples. Industrial purity of the working fluid is one of the most important requirements for circulating lubrication systems. For a circulating lubrication system of machines, this study determines the parameters affecting the industrial purity of the working fluid during operation, as well as identifies the relationship between them. Accordingly, an analytical solution is developed to design a mathematical model that derives the relationship between the main characteristics of the circulating lubrication system, namely industrial purity of the working fluid, rate of contaminant inflow, and cleaning efficiency. Oil purity in the circulating lubrication system is observed to be directly proportional to rate of contaminant inflow and inversely proportional to contaminant removal efficiency. Industrial purity of oil and contaminant inflow into oil are experimentally determined for the circulating lubrication systems of the T-100 TMZ, T-180/210 LMZ, and K-500-240 KhTGZ turbine units. Tp-22S mineral turbine oil is used as the working fluid. Experimental data are obtained confirming the efficiency of using polyamide filter materials in oil tank filters. After upgrading the standard filters of the oil tank of the T-180/210 LMZ turbine unit, the amount of solid particles in the oil decreases by 5.8 times, with the purity corresponding to classes 6 and 7 of GOST 17216–2001.
