causing noise and abnormal vibration is many, either because of fuel dispenser�or exterior elements (pipe trouble). Therefore, it is first to exclude exterior reason of fuel dispenser, then interior one when overcome the above situation. After that, examine strainer and clean dirty. Next parts being checked is overflow valve. Tight spring will stick valve core and generate large noise and vibration. In addition, don’t pursue large flow rate through adjusting spring extensively, since that will shorten the service life of fuel dispenser due to large system pressure. If noise is still large after the above maintenance, pump should be disassembled so as to examine vane and spri fuel dispenser ng whether broken. If these parts are broken the outlet flow fluctuation of pump would be enhanced, as well as noise and vibration. The solution method is to change a new vane and spring. Leakage Leakage is fuel dispenser divided as two categories, namely, inner leakage and outer leakage. Under the high oil pressure in hydraulic system oil is leak from high pressure area to low area, which is called inner leakage. The abrasion of vane, rotor and frame result in extensive inner leakage so as to reduce delivery volume of fuel dispenser. The outer leakage is the one oil le fuel dispenser ak from inner hydraulic system into outer, which increase unsafe environmental elements except from affecting the normal working performance of pump. To change a new oil seal when find a leakage coming from the root of pump axis. Be sure that don’t make a mistake in installing oil seal. Diagram 2-7 show the correct position ----- the labium of oil seal should face to inner chamber. In addition, tight V wheel also hurts the surface of oil seal next to pump axis so that its capacity is invalid. Diagram 2-7 The most leaking sections are the connecting face---- between pump cover and pump frame, between pump frame and vapor separator, place of cap nut of overflow valve. All of reasons are damaged seal loop or seal gasket, thus change new sealed components as soon as quickly.

d the NYSE with Archipelago, an electronic- trading exchange partly owned by Goldman. The deal benefited the investment bank in so many different ways that some Wall Street wags joked how Mr Thain had not left the firm after all. Apparently in part to silence such critics, Mr Thain has chosen Citigroup, not Goldman, as the NYSE s adviser for the Euronext deal. Another attraction of Euronext to the NYSE is that it caters for trading in both shares and derivatives, something the London exchange cannot offer. One way to maximise the value of a trading platform is to push more transactions through it, and although it is hard to invent new shares to trade, dreaming up new der fuel dispenser ivatives is a piece of cake. Above all, through a European merger Mr Thain may hope to regain access to the new-listing business. This is clearly a goal of NASDAQ, too. In 2000 nine out of every ten dollar fuel dispenser s in the world s initial public offerings were raised in America. Last year nine out of every ten dollars were raised outside America—which Mr Thain bemoaned at a dinner last month with Silicon Valley luminaries. The flight of initial offerings, notably to the LSE s Alternative Investment Market, has been blamed on America s costly Sarbanes-Oxley law fuel dispenser , introduced after the collapse of Enron. One of the biggest fears of investors in London is that if NASDAQ buys the LSE, it will bring with it the dead hand of Sarbanes-Oxley. “Whatever happens, the regulatory domicile must stay in London. Apart from that, we have no particular prejudice who owns the exchange,�says Peter Montagnon, of the Association of British Insurers, whose members control about one-sixth of the shares on the LSE. “What makes London attractive is its regulation. One of the things we regulate well is listings.�Although regulatory arbitrage may now be its main goal, NASDAQ has a long history of overseas expansion, little of it happy—a lesson worth pondering during today s merger frenzy. In the late 1990s the exchange struggled in both Europe a
