semester 2005-2006
  • S R Kale
  • Lecture

General Arrangement (G.A.) Drawings
2
Background
  • Schematic / PI drawings are available,
    equipment sizing and selection has been done.
  • NEXT Need data on various equipment to integrate
    with one another.
  • What data is needed? gt G.A. drawing.

3
Overall features
  • About the manufacturer gt Title block
  • Name plate rating
  • Model no., Date of manufacture
  • Ratings (capacity, design parameters)
  • Working substance
  • Electrical input/output
  • Terminal points Scope of supply (items included
    or excluded)
  • Related drawings

4
Mechanical dimensions
  • Overall dimensions Maximum, moving dimensions,
    space during operation, space for maintenance,
    clear space,
  • Movement space, rails,
  • Mating pipe flanges locators, size, type
  • Mechanical coupling Shaft locators, diameter,
    keyway size,
  • Mountings flange mounting PCD, thread/hole,
    locator pins,
  • Mounting locations base plate, mounting
    brackets, locations and sizes,

5
Civil dimensions
  • Weights and forces
  • Static loads
  • C.G. locations
  • Dynamic loads
  • Speed
  • Allowance for expansion,
  • Foundation
  • Location of holes for mounting bolts
  • Size of foundation bolts

6
Handling requirements
  • Weights
  • C.G.
  • Lifting points
  • Location of holes
  • Hook size
  • Special devices for lifting
  • DO NOT LIFT from ,

7
Electrical requirements
  • Power requirements V, A, p.f., 1 or 3 phase
  • Earthing requirements
  • Load type reactive,

8
G.A. Drawing of Motor
9
G.A. drawings - Examples
  • Examples of pump, chilled water system, Loco,

10
Slip-up (challenge!)
  • Flanges dont match during erection
  • Foundation bolts are off
  • Piping and cabling become a jungle
  • Inadequate capacity
  • (e.g. HOT crane at Badagrah)
  • Foundation dynamics are poor

11
Lecture summary
  • Make or procure G.A. drawing from the
    manufacturer/supplier, ask for more information
    if not given gt Integrate the information to make
    the plant.
  • NEXT STEP Make plant design, O.K. for
    construction.
