HYDRAULICS AND PNEUMATICS MACHINES

Pneumatic systems are mechanical systems that use compressed gases. They are similar to hydraulic systems which are mechanical systems that use liquids in the transfer of forces. Pneumatic systems are almost everywhere in the modern world. Dentists use pneumatics to operate drills used in removing tooth decay, carpenters use pneumatics to perform drilling operations, and scientists use pneumatics to control the operations of satellite launch vehicles. Pneumatic wrenches are used by automobile mechanics to tighten bolts and nuts, pneumatics hammers are used by construction workers to break up pavement, gas turbines in jet engines and air brakes inject engines and air brakes in heavy trucks and railway trains are operated based on pneumatic principles.

Examples of hydraulic and pneumatic devices are;

  • Air brakes on buses and trucks
  • Hydraulic jacks
  • Simple garden sprinkler
  • Reaction turbine
  • Water wheels
  • Centrifugal pump
  • Pressure sensors
  • Pipe organs
  • Cable jetting
  • Pneumatic bladder
  • A vacuum pump
  • Pneumatic mail system
  • Exercise machine
  • Pressure switches
  • Pneumatic air gum
  • Power wrench

 

COMPONENTS AND MODE OF OPERATION OF THE MACHINE

The air used in pneumatic tools is supplied by an air compressor. This air compressor squeezes the air to a pressure that could be able to drive the tool either in a reciprocating motion that is back and front or in a rotary motion, and circular motion. The compressed air causes the piston in the tool to move back and front inside the cylinder. It is the piston that pushes the striking device of the tool. In an air brake the piston supplies or releases the brake after receiving several blades. The rotor spines as the compressed air is forced against each blade in turn.

USES OF PNEUMATIC MACHINE

  1. It is used in producing rotary motion used in a grinder, power wrenches, power drills
  2. It is used in gear changing
  3. It is used power-assisted steering
  4. It is used in clutch operations.
  5. It is used in operating turbines
