Task 1• Basic Hydraulic PrinciplesA simple hydraulic system consists of the following components• Hydraulic fluid,• Pistons or cylinders,• Cylinders,• Accumulator or oil tank,• Working mechanism and• Safety devices. They control various equipment that transmit the force carried by the hydraulic fluid in a specific environment. In modern systems, hydraulics transfer precise and rapid forces, even in small pipes of any shape and over a long distance. • Pascal's Law: Pascal's law, framed by Blaise Pascal, states that “the pressure applied to any part of a confined fluid is transmitted to every other part without loss. The pressure acts with equal force on all equal areas of the containment walls and perpendicular to the walls. » This is the basic principle of the hydraulic system. • Hydraulic pressure and force: Pressure can be defined as “the force acting on a unit area, applied in a direction perpendicular to the surface of the object”. Pressure = Force/Area. This is stated as the force exerted by a fluid on a unit area, on the surface anywhere in the system. http://www.brighthubengineering.com/hydraulics -génie-civil/43171-quels-sont-les-principes-de-base-de-l'hydraulique/Brake systemThis illustrates Pascal's law in a hydraulic press, and this principle is also used in airplanes to brake. There is a mechanical advantage you can create. where a small force is used to obtain a larger force elsewhere. Directional control valve • Check valve • Directional spool valve • Directional poppet valve Pressure control valve • Control task: variable throttle • Switching task: fixed throttle Electro-hydraulic valve • Servo-hydraulic valves • Hydraulic valve proportionalhttp://www.dta.eu/hydraulics/hydraulic-valvesTask 2Hydraulic fluidThen transmitting the pressure of the fluid used, lubricates the parts of the hydraulic system and also acts as a coolant. The oil used has a low viscosity to facilitate filling of aluminum pipes and all other pipes. As the oil heats, it maintains its properties over a wide temperature range. Three types of hydraulic oil are used: • Vegetable, • Mineral • Synthetic based. Vegetable They are colored blue and made from alcohol and castor oil. They are mainly used in older aircraft where natural rubber seals are used. These vegetable oils can also cause corrosion or sludge. Minerals They are colored red and are based on a widely used kerosene-based petrochemical. They have good lubricating properties which, in small quantities, resist corrosion and foaming. They are stable and have a low viscosity that changes with temperature. Mineral oils are flammable and cannot be used with rubbers. SyntheticsThese are purple in color and are less flammable than mineral oil. They attract water because they are based on synthetic phosphate eaters. They also attack certain paints and plastics.
