  1. pneumatic and hydraulic systems.
  2. What are hydraulic systems and how do they work?
  3. Hydraulic systems use liquid under pressure to do work.
  4. It uses the in compressibility of liquids as its advantage.
  5. Multiplying a force is also important to transmit force.
  6. There are several examples of hydraulic systems such as airplanes, breaks,
  7. Jax and more
  8. airplane hydraulics.
  9. The reservoir it holds a hydraulic fluid which is a fuel.
  10. This is the base of the system.
  11. It has a supply and return line which that's
  12. a fluid flow through the entire system repeatedly.
  13. There is also a pressurize er which maintains a positive flow of the system
  14. pumps.
  15. A prompt pressurize is foods at a constant rate
  16. in an airplane, either engine driven pumps or electric pumps are used
  17. just in case these pumps fail in an emergency situation
  18. there's a hand pump,
  19. filters,
  20. a filter removes any impurities in the hydraulic fluid of fuel.
  21. This is so that it doesn't negatively impact the hydraulic system.
  22. There are usually filters on all main parts of the airplane,
  23. such as the supply line and return line
  24. valves. A valve controls the flow of fluids.
  25. There are four types of valves in an airplane which all have different functions.
  26. Firstly, a check valve is a valve that flows one way
  27. which prevents any malfunctions.
  28. Secondly, a shut off valve stops the flow of the fluid
  29. which is used in case of emergencies.
  30. Thirdly,
  31. a pressure reducing valve decreases pressure in
  32. certain areas for the system to function.
  33. Finally, a sector valve changes the direction of pressurized fluids
  34. through the,
  35. through the rotation of the valve.
  36. The acute er
  37. this is where the hydraulic pressure is converted to mechanical action.
  38. The cuter piston
  39. moves from the pressure of the fluid
  40. and the fluid is redistributed back to the reservoir.
  41. This controls the brakes, steering controls and lightning.
  42. The accumulator.
  43. The accumulator holds pressurized fluids
  44. have pressurized water and air.
  45. It can provide pressurized fluids on the actuator needs more pressurized fluid.
  46. This is often used for emergencies,
  47. such as when the pump fails or the pressure of the fluid decreases.
  48. The largest manufacturer of airplane hydraulic systems is a bowling company,
  49. hydraulic brakes.
  50. A car moves when the gas pedal is pressed and the energy is transferred to the engine
  51. and the gas pedal is released.
  52. It slowed this down as there is no force to keep it moving,
  53. it will stop eventually, but there is no way to tell the timing.
  54. This is why brake pedals are used.
  55. When the brake pedal is pressed, a vast hydraulic system begins to stop the car.
  56. The fourth from the brake pedal goes to the
  57. push rod servo and then the master cylinder,
  58. the master cylinder converts the mechanical force
  59. into hydraulic force by using pistons.
  60. This creates pressure in the entire hydraulic system.
  61. The brake fluid goes to all four tires.
  62. When the brake pedal is pressed of force is transmitted
  63. but after it remains there creating no force
  64. this makes the car stop. This is why there is a slight acceleration before breaking
  65. adala jacks.
  66. A hydraulic draft uses liquids to do heavy lifting.
  67. It uses a two main basic principles of levers and multiplying of force
  68. as a small piston and a larger question, which is connected by a tube
  69. due to the rules of force multiplication. A small force on the small piston
  70. results in a larger force on the large piston.
  71. The ability of levers to sustain large loads
  72. allows the hydraulic jack to lift heavy items.
  73. The liquid transferred from the reservoir to both pistons creates the force
  74. they are used for car, horse and elevators.
