Steam revolution: pre-visit exhibition slideshow Presentation Transcript

  • 1. Pre-visit exhibition walkthrough The steam revolution
  • 2. This exhibition walkthrough provides an overview of the: • Physical layout and exhibition sections • Key objects • Audiovisuals and interactives • Relevant online teaching and learning resources Exhibition entrance The steam revolution
  • 3. Go on a journey to discover the development of steam technology — from the scientific experiments of the 1600s to the steam turbines that power electricity generators today.
  • 4. Original engine room The Steam Revolution gallery was the original engine room of the Ultimo Power House, which generated power for Sydney’s electric trams. The engine room was completed in 1899 and remained in use till 1963.
  • 5. The steam revolution exhibition floor plan
  • 6. Section 1: Introduction Section 2: Steps towards steam Section 4: Steam goes bush Section 3: Turn on the tap Section 5: Designed for power Section 6: Steam on the move Section 7: All work … no play
  • 7. Section 8: Roll up! Roll up! Section 9: Designed for speed Section 10: The city electric Section 11: The Earl Spencer’s cargo Section 1: Introduction Section 7: All work … no play
  • 8. See how traditional methods of work changed after the arrival of steam power about 300 years ago. The video shows a sawmill engine working at a relentless pace. Section 1: Introduction
  • 9. Section 2: Steps towards steam 1 This section covers the scientific discoveries about air pressure and the nature of steam that led to the invention of the Boulton and Watt rotative steam engine Interactive: Feel the weight of air Scientific discoveries about air pressure and the nature of steam Video: Boulton and Watt – how their engines work (2 min) Interactive: Boulton and Watt engine model
  • 10. Interactive: Feel the weight of air Find out what makes the piston lift the weight. Step 1: Turn the red handle to pump air out of the cylinder below the piston. What happens to the weight? Step 2: Pull the yellow handle down. Can you feel the air pushing down on the piston? Step 3: Press the air valve lever on your right to let air back in the cylinder. What happens? Some early scientific discoveries: 1654: Otto von Guericke – What did he demonstrate? 1690: Denis Papin – What did he invent and what did he use to move a piston inside a cylinder? 1698: Thomas Savory – What did he invent? 1712: Thomas Newcomen – What was his steam engine able to do?
  • 11. Interactive: Working model of our Boulton and Watt engine Touch the button to bring the model to life. This model reveals the separate condenser which improved the engine efficiency at least threefold. This is a scale model of the engine upstairs. Video: Boulton and Watt – how their engines work (2 min)Interactive: Put steam to work [This interactive is to be replaced]
  • 12. Section 3: Turning on the tap Follow the development of Sydney’s water supply and look at the huge cylinder from Botany Pumping Station. Compare it with the cylinder of the engine behind you and imagine how big the Botany engine was. These mechanical parts ensured that steam entered the cylinder above and then below the piston, over and over. Cylinder with timber insulation
  • 13. Stone water filter Section of wooden pipe that formed part of Busby’s Bore Bucket Basin and ewer Until the 1850s, few people in Sydney had taps in their houses. Most had to pump water by hand from public pumps and wells and then carry it home, walking up to half a kilometre each way.
  • 14. Interactive: Pump some water Get an idea of the effort involved in using a hand pump Audio: ‘Not a drop fit to drink’ Hear what people thought about Sydney’s water supply in the 1800s (3 min)
  • 15. Section 4: Steam goes bush This section is set around a Maudslay steam engine. Brought to Australia in 1837 along with two boilers, it drove a brewery and flour mill at Goulburn. Maudslay steam engine Wagon boiler Boiler tools
  • 16. The story of Henry Maudslay and his team of engineers is told here. They brought new levels of accuracy and standardisation to manufacturing.
  • 17. Section 5: Designed for power Compare these high-pressure steam engines developed in the 1800s. They could fit into confined spaces in factories or boats. Find each engine’s cylinder. One (compound) engine has two cylinders to make better use of steam. Table engine Inverted vertical engine Horizontal engine Video: Simple and compound engines [behind the plinth]
  • 18. Section 6: All work … no play This section looks at the large steam engines that drove factory machinery all around the world before World War II. The relentless pace of the machines made work monotonous as well as noisy, dangerous and dirty. Marshall compound steam engine Printing press Interactive: Corliss mill engine model Weaving loom Pulleys to transmit energy from engine to machinery
  • 19. Horse-drawn fire engine Portable steam engine AV: … making steam move (3 min) AV: Fire! Fire! (4 min) [behind the engine] Section 7: Steam on the move This section displays ‘portable engines’, which could be moved from place to place to do their work. These high-pressure engines were compact and light enough for horses to pull. Does this make them early hybrid vehicles?
  • 20. Hard work before steam Hand tools like these were used on farms in Australia and Britain before mechanisation. Great skill and strength were needed to get results. Model plough Shearers with hand shears
  • 21. Steam on the farm Farm workers saw mechanisation as a mixed blessing. It made some jobs easier, but people struggled to keep up with the relentless pace of machines. Many people had to move to cities because there were fewer jobs on farms.
  • 22. The first fire brigades In the days before governments employed fire-fighters, fire brigades were owned by insurance companies. These brigades would only put out fire in buildings insured by their own company.
  • 23. The Fire King Merryweather, the maker of our horse-drawn steam fire pump, was so successful that he was nicknamed the Fire King. The engine was made at Greenwich in England.
  • 24. Section 8: Roll up! Roll up! In this section you’ll find out about fairgrounds and their steam-powered entertainments. Tangye engine that powers two carousel horses Interactive: View a fairground Interactive: Stereoscopic photographs
  • 25. Roll up! Roll up! Travelling fairs brought a splash of gaiety and colour to people whose lives were spent in industrial surroundings.
  • 26. Section 9: Designed for speed This engine ran at the high speed needed to turn an electricity generator. The engine-generator set supplied electricity to machinery in the Uncle Toby’s Oats factory at Lane Cove in Sydney. Belliss and Morcom two cylinder engine Exciter to start the generator The switchboard that controlled electricity supply to the factory is displayed to the right Peebles generator
  • 27. Section 10: The city electric This section looks at the spread of electricity and the turbines that generated it. AV: Metropolis (2 min) Interactive: Light up Sydney Parsons turbines
  • 28. Interactive: Light up SydneyCity lights See how electricity produced by steam turbines transformed the way people worked and lived. Spin the generator to light the Imperial Arcade model. How many rooms can you light up?
  • 29. Interactive: Make power by impulse Interactive: Make power by reaction Cream separator made by turbine pioneer De Laval Interactives explaining two basic types of turbine
  • 30. Fantasies and failures Steam power inspired many inventors in the 1800s. Here are two experimental models made by Lawrence Hargrave. End of the line Turbines and petrol engines began to take over in most fields after 1900. Stirling class locomotive model Triple expansion (compound) engine modelSteam turbineAircraft model engine
  • 31. Parsons turbines Parsons turbines worked because they had many small blades to spin a shaft very fast. We have lifted up part of the turbine so you can see them. Earlier turbine designers used a single blade, which in some cases self-destructed at high speed. Video: A simple turbine – how it works [behind the plinth]
  • 32. Interactive: The electric rollercoaster - See how ‘electricity demand’ changes from hour to hour and season to season
  • 33. Section 11: The Earl Spencer’s cargo This display looks at the arrival of the first steam engine in Sydney in 1813 and early use of steam in the colony. The main object is a large broken boiler. Day Street boiler The site where this boiler was found was once John Struth’s engineering works. The boiler might have exploded, or it could have been taken there to be broken up and melted down.
