Diagram 2-7: Installation of framework oil seal Important notices to disassembly and reassembly As pump and motor are the resource of power one should pay much attention to disassembly and reassembly of pump. Be sure that cut power prior to maintenance. Disconnecting V belt in case to cause any accident, prepare a container to collect oil that will pollute environment fuel dispenser . Grind the semicircle keyway on pum fuel dispenser p axis using sand paper before disconnecting pump cover in order not to scratch framework oil-seal by burr. All components should be carefully cleansed prior to reassembly of pump in case dirty substance flow into pump and cause new trouble. Turn rotor and examine the vane working state after installing rotor subassembly and spring in pump chamber. Meanwhile, be sure that the position of vane should higher than rotor, low pump frame even. A little grease should be daubed on the inner of brass bushing and framework oil-seal when installing pump cover. When installing the bolts of pump cover each tension is coherent as the sequence that opposite bolts go first. After reassembly of pump to check inspect the rotation of pump. The seal ring between pump and vapor-recovery should be carefully examined before installing in case of leakage. Be sure that the two V wheels o fuel dispenser f motor and pump in line, having any obvious jump and wave. Internal gear pump Fuel dispenser is mounted now with two types of internal gear pump, namely, involute gear pump and inner cycloidal gear pump. In the former type a piece of crescent clapboard is installed between small gear and inner gear, dividing suction chamber with discharge chamber. However, in the latter type the division is realized through joint between gears, without clapboard. The smaller gear in internal gear pump is driver. Diagram 2-8 illustrate above gear pumps. Internal gear pump characterized that compact, light in weight, low noise and long service life still has disadvantage of complicated gear figure and high cost. Domestic market now has these two kin

America has a huge deficit largely because it saves too little. Politicians, however, prefer to blame China. The final nail in the coffin of Bretton Woods 2 is that the increase in China s external surplus has been much too small to account for America s deficit. Estimates for 2006 suggest that China s current-account surplus has widened by $140 billion since 1997, whe fuel dispenser reas America s deficit has expanded by fuel dispenser $720 billion. By far the largest counterpart to America s deficit today is the group of emerging oil exporters, which have moved from rough balance in 1997 to an estimated surplus of $425 billion this year—much larger than emerging Asia s total surplus of $250 billion. Oil exporters are determined not to repeat their mistakes after previous oil-price jumps. They have been much more cautious in spending their revenues, saving a larger share than in the past. So far, the bulk of petrodollars has probably gone into relatively liquid dollar assets. But these countries have greater reason than Asia to invest in non-dollar currencies, because they trade much less with America. And petrodollars are mostly managed by investment funds that aim to maximise returns, so oil exporters assets are more footloose than those of Asian central banks and could quickly shift out of fuel dispenser the dollar if it starts to slide again. Too much of a good thing Mr Bernanke has argued that America s deficit is the innocent by-product of a saving glut in emerging economies. If the rest of the world saves more than it invests (ie, runs a current-account surplus), then America has to run a deficit. The implication is that America s deficit is more sustainable than generally thought. But this still begs the question of why emerging economies have excess saving when their return on investment is higher than in rich countries. A paper presented by Raghuram Rajan, chief economist of the IMF, at this year s annual symposium of the Federal Reserve Bank of Kansas City offers a tentative explanation. Mr Rajan argues that
