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. Grind the semicircle keyway on pump 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 of motor and fuel dispenser pump in line, having any obvious jump and wave. Internal gear pump Fuel dispenser is mounted now wi fuel dispenser th 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 illustra fuel dispenser te 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

l energy security.� In a liberalised market, private firms should provide storage to take advantage of the difference between summer and winter gas prices. But not everyone is convinced that the market is delivering. Planning problems are one reason worried residents scotched a planned gas store beneath Lancashire earlier this year, and other projects have faced long delays. Mr Darling s new guidelines should make it harder for planners to refuse applications. Economics is another reason. Storing gas is expensive, partly because reservoirs need to be pumped full of unrecoverable “cushion gas�to maintain pressure, and partly because storing gas for the future means giving up the opportunity to sell it today. “When prices are low you don t need storage because gas is abundant,�says Andy Morris of ILEX, an energy consultancy. “When prices are high, and you do need it, it s very expensive to build.�Instead firms, like the government, have relied on new import infrastructure to meet most of the winter demand. After last winter, that looks optimistic. Nevertheless, investment in storage has risen as spreads between summer and winter prices have widened. Ten new projects are planned, which together should double Britain s storage capacity by 2010. But that will be cold comf fuel dispenser ort to firms and consumers anticipating another tight winter in six months time. “The market is too s fuel dispenser low,�says Jonathan Stern, an analyst at the Oxford Institute of Energy Studies. “By the time it was signalling the need for more storage it was too late.� The biggest problem, adds Mr Stern, is that markets find it hard to insure against rare, unpredictable but catastrophic events such as an explosion in a pipeline or a terrorist attack—or the fire that shut down Rough. With that in mind, one question fuel dispenser being considered by the government s energy review is whether the state should step in and set up a “strategic�gas reserve (something similar already exists for oil).
