safety. The design of filling station should be accorded with GB 50156-2002 Design and construction regulation of vehicle filling station, fuel dispensers�installation position and distance with building should abide with the relative stipulation in GBJ16-87 Fireproof regulation of Construction Design. Installation and debugging of fuel dispenser are part of filling station business, and affect the normal business and safety of station, which is important sector in preventing accident of filling fuel dispenser station. Due to many models of fuel dispenser exist in domestic market, this chapter only introduce general technology and important notices about installation and debugging of common fuel dispenser. Thereby, the relevant staff also consult User’s handbook to install and debug fuel dispenser. Article I Installation Check and accept after open packing Check certificate of quality and operation instruction Inspect whether exist damaged parts or loose connecting point Check nameplates of fuel dispenser sand explosion-proof motor. Inspect accessories and spare parts whether accord with specs, model and quantity. Fixation of fuel dispenser Fuel dispenser should be installed under awning where preventing rain and sunlight in every season as operation. The height of awning is convenient to entry and exit of large vehicle. Fuel dispenser should be installed on the safety island. There are two reasons for doing that. One is to avoid collision between fuel dispenser and vehicle. The other is to promote the environmental security of fuel dispensers. Being higher than ground, vapor density at the bottom of fuel dispenser is thinner than that of ground, benefiting enhance explosion-proof performance. Fuel dispenser’s pedestal should be installed on the special concrete base, fixed by the ground bolt or expansion bolt. Diagram 7-1 shows the pedestal install fuel dispenser ation drawing of fuel dispenser. Diagram 5-1: Pedestal installation drawing These pipes of delivery (φ38mm), lead, signal and grounding should be fuel dispenser

l median wage of American graduates has fallen by 6% since 2000, a bigger decline than in average wages. In the 1980s and early 1990s, the pay gap between low-paid, low-skilled workers and high-paid, high- skilled workers widened significantly. But since then, according to a study by David Autor, Lawrence Katz and Melissa Kearney, in America, Britain and Germany workers at the bottom as well as at the top have done better than those in the middle-income group. Office cleaning cannot be done fuel dispenser by workers in India. It is the easily standardised skilled jobs in the middle, such as accounting, that are now being squeezed hardest. A study by Bradford Jensen and Lori Kletzer, at the Institute for International Economics in Washington, DC, confirms that workers in tradable services that are exposed to foreign competition tend to be more skilled than workers in non-tradable services and tradable manufacturing industries. Ride on, Ricardo None of this makes a case for protectionism. Offshoring, like trade, is beneficial to developed economies as a whole. The increased mobility of capital and technology does not invalidate the theory of comparative advantage, as some commentators like to argue. China and India cannot have a comparative advantage in everything; they will export some things and import others. Emerging economies comparative advantage will largely remain in labour-intensive industries. A country s trading pattern is determined by its relative capital intensity compared with other economies. Emerging economies still have relatively little capital, so they are unlikely to become significant capital-intensive exporters until their capital-to-labour ratio catches up. That will take time. Developed economies will retain their comparative advantage in knowledge-intensive activities because they have relatively more skilled labour, fuel dispenser but that advantage will be eroded more quickly in future. The developed economies as a whole will still benefit hugely from trade with emerging economies. fuel dispenser
