GENERAL INTRODUCTION TO ASSESSMENT STATEGY

Throughout the module you should do the following.

Study relevant course notes. Study the recommended textbooks. Use the standards publications available in the library. Make use of suitable web sites. Make use of journals on fluid power. Make use of manufacturers catalogues. (RS, NORGREN, REXROTH and so on). Make use of the standard information pack from the British Fluid Power Association.

In the design parts, you should use the computer software PneuSim Pro. The context help contains

diagrams, pictures and symbols.

Your assignment should be structured with headings and subheadings. The work must be your own. Copies

of pages from the internet or from any other source should only be added as reference material. This should

be clearly identified and cross-referenced in your text (e.g. diagram numbers and appendix numbers).

You may use computer packages such as word to produce your work and scan in pictures. You may do the

work in hand writing and paste in pictures and diagrams. What ever method you use, make sure that the work

is identifiable as your own unique style and your research.

ASSIGNMENT DETAILS

1. STANDARDS Compile a li st of the current f lu id power standards (I SO and others) used in the design,

construction, commission ing and operati on of the machine. For each state the purpose. Th is

could be a very large list: i t is up to you how many you can fi nd.

Study the standards to do with ci rcuit drawings and answer the fol lowing questions.How should the symbols be laid out?

How should the symbols be identif ied and numbered?

What are the standard dr awing sizes in the ISO standard?

What other details shou ld be included on a drawing?

Study the standards to do with circuit symbols and answer the fol lowing questions.What kind of l ine shou ld be used to show pilot li nes?

What kind of li ne shou ld be used to show pressur e lines?

How do you indi cate a junction of two li nes?

2. HYDRAULIC CIRCUITAttached is the circuit diagram of a hydraulic machine that was designed and built some time ago and it no

longer conforms to modern standards. The circuit is for a machine to move heavy bars in one direction and

then another. There are two installations.

Study the cir cuit carefull y and then wr ite a report containing the following.

I denti fy the function of each actuator and describe how i t is controlled. I denti fy where the circuit diagram does not conform to current standards. Redraw the circuit to cur rent standards using software such as PneuSim Pro or traditional

draf ting methods.

Your completed drawing must be in A3 size and must include the following.

Al l components must be numbered with text boxes fol lowing the ISO standard. Border Titl e Block correctly fil led in. L ist of components (bil l of material)

IMPORTANT : Consul t with your tu tor to ensure that you understand the work to be done before you

commit yourself to any substantial amoun t of work.
