1. HYDRAULIC FILTRATION Fleetguard Filters Private Limited Proprietary Information

2. HYDRAULICS Uses principle of the flow and pressure of fluids to do the work. FORCE - F 1 P RESSURE P Pressure applied on a confined fluid is transmitted undiminished in all directions and acts with equal force on equal areas and at right angles to them . BASICS OF HYDRAULICS PASCAL’S LAW Proprietary Information

3. Close loop System Open loop System Oil Flow path: Reservoir Pump – System – Reservoir BASICS OF HYDRAULICS Oil Flow path: Reservoir - Pump – System – Re-circulates to pump. Additional pump is required to replenish the oil in system Proprietary Information

4. Major Components of Hydraulic System Prime mover: Electric Motor / IC Engine Pump : Gear Pump, Vane pump, Piston pump. Control Valves: Direction Control, Flow control, Pressure control Valves Accumulators: Bladder type, Piston type, Diaphragm type. Filters : Pressure line, Off line, Return, Suction filters. Actuators: Cylinders , Hydraulic motors. BASICS OF HYDRAULICS Proprietary Information

5. Looking at the modern machinery requirements, hydraulics play a very active & crucial role in machine drives. As the high-precision machinery uses advanced hydraulic components like axial pumps & proportional valves, maintenance of such elements is the most vital necessity. In hydraulics more than 80% of problems are due to contaminated fluid; so it is important to keep system fluid very clean & free of contaminants. NEED OF HYDRAULIC FILTRATION Proprietary Information

6. Function of Filter : It keeps the oil clean by separating the particulate contaminants, dust and moisture. Types of Hydraulic Filter Suction Strainer/Filter Return Line Filter Pressure-line Filter Breather Filter Hydraulic Filtration : It is the process of separation of contamination ( unwanted/harmful/foreign particles) from the hydraulic oil . Filter is a component of Hydraulic System incorporated to maintain fluid cleanliness as per pre-determined design needs. BASICS of HYDRAULIC FILTRATION Proprietary Information

7. Applications A pplications where contamination is very high and in-built system filters are inadequate to maintain system cleanliness level. Systems with high volume of oil. e.g . Turbine Lube System, Steel Mills, Generator Systems. HYDRAULIC FILTRATION Features: This is independent of the main hydraulic system. The filter elements can be replaced without stopping the main system. Single offline filtration unit can be used in multiple systems. Proprietary Information Off-line Filtration

8. Tank Top Filters To block the system generated contaminants entering into the reservoir. Tank top filters are low pressure & economical . Filters mounted on tank top require less space. In-line Filtration Pressure Line Filters Pressure line filters are used in the hydraulic system to protect critical components e.g. proportional valves and servo valves . These filters are used for the pressure range from 40 bar to 600 bar. HYDRAULIC FILTRATION Proprietary Information

9. Spin on Filters Spin on filters are low pressure hydraulic filters used in return line or as suction line filters in hydraulic systems. These filters are convenient to replace as compare to cartridge type filters. Working pressure up to 30 bar. Air Breathers Breathers prevent particulate contamination present in the air from entering in to the oil tank. These are mounted on hydraulic oil tank. Return Line Filters The systems with variable displacement pumps and hydraulic motors requires return line filters. These filters prevent the particulate contamination from entering the oil tank. The return line filter are low pressure filters. W orking pressure up to 10 bar . HYDRAULIC FILTRATION Proprietary Information
