STRUCTURED ANSWER



               QUESTION 1
                    a.     The THREE (3) advantages of pneumatic system are:


                                  has  several  operation  modes;  can  be  fully  automated,

                                   manually operated, and semi-automated mode.
                                  clean and cheap

                                  the accuracy of the end results is moderate.
                                  reduce production time and cost – mass production.



                    b.     The FIVE (5) blocks from diagram of pneumatic system.


                                  COMPRESSOR:  Air  taken  in  atmospheric  pressure  is

                                   compressed  and  delivered  at  a  higher  pressure  to  the
                                   pneumatic system. It thus transforms mechanical energy into

                                   energy.

                                  AIR STORAGE SECTION: stores the compressed air. Its size is

                                   defined by the capacity of the compressor.


                                  AIR CLEANING SECTION: Mainly divided into main line filter,
                                   air dryer and mist separator.


                                  AIR CONDITIONING SECTION: Air conditioning section or air

                                   service unit is a combination filter regulator lubricator and
                                   called a FRL.


                                  CONTROLLING  SECTION:  Converts  energy  stored  in  the

                                   compressed  air  into  mechanical  motion  which  is  used  to
                                   move actuators into various positions.


                                  ACTUATOR:  Transform  the  potential  energy  of  the

                                   compressed  air  into  mechanical  work.  Shown  is  a  linear
                                   cylinder, it can also be a rotary actuator or an air tool etc.
