Wear and abrasion by existing particles.Ingression during maintenance and topping of new liquid.There are various sources of contamination: Small particles enter the fluid due to wear of the system and the return line filter takes care of them. The return line filter is located at the end of the return line. Reservoir fluid can get contaminated from small atmospheric dust particles coming from the air breather. A suction line filter is located at the suction side of the pump and prevents the contaminants in the reservoir fluid from entering the hydraulic system. A filter preventsĬontaminants from entering the hydraulic system and ensures satisfactory working with minimum maintenance. Management Componentsįilters are another important component in any hydraulic system. As the pressure increases beyond a certain prescribed limit, the relief valve will bypass the fluid into the tank and maintain the system pressure below the maximum level. The pressure relief valve is an NC (normally closed) safety valve for the hydraulic system. This pump-motor unit together decides the power of the system and its selection limits the maximum pressure and maximum flow rate that can be generated from the system. The most frequently used pumps are reciprocating piston pumps, vane pumps, and gear pumps. It can be one of many different types depending upon the application. The hydraulic pump develops hydraulic energy. The selection of the primary energy source doesn’t affect the performance of the hydraulic system, even though it may affect the weight, vibration, noise and size of the system. This mechanical energy goes into the hydraulic pump to generate hydraulic energy (pressure and flow). The primary energy source converts input energy into mechanical energy. The primary energy source can be either an internal combustion engine (for mobile applications), a DC motor powered by DC batteries (mostly used on ships) or a 3-phase AC motor (for industrial application). The primary energy source is the unit which will supply mechanical energy to the hydraulic pump. The reservoir stores hydraulic fluid and protects it from contamination.
