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 spring 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 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 leak from inner hydraulic system into outer, which increase fuel dispenser 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 axi fuel dispenser s 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. fuel dispenser

ure, it is currently the fastest-growing rich-country economy (see article). Before declaring deflation dead, however, policy-makers need to hack through a statistical tangle. According to the Bank of Japan s preferred measure, core consumer prices (which excludes fresh food) showed a year-on-year increase (albeit only 0.1%) in November and December two small nails in deflation s coffin. But Japan s national accountants, who compiled last week s surprising growth figures, have a more dispiriting view of deflation. By their measure, prices appeared to fall by 1.6% in the year to the last quarter the deflationary monster is still alive and well. In fact, both measures are flawed and give a misleading picture of what is really happening in the economy. Japan s core rate overstates inflation, because unlike in other countries, it includes energy prices, which are surging. Equally, in an economy undergoing profound structural change and suffering from deflation, it is a particularly daunting task to know how much of a change in spending is due to a change in real output, as opposed to a change in prices. This is why the only sensible measure of Japan s economic performance is nominal GDP, ie, total national output measured in money not volume terms. When inflation is high, fuel dispenser only changes in real output offer any sensible guidance to how the economy is performing. But in a period of deflation, nominal changes matter much more growing real GDP means little if the economy is contracting in money terms. Between 1997 and 2004 Japan s nominal GDP shrank by 5%, while America s spurted by 42%. The good news is that in the year to the fourth quarter of 2005 Japan s nominal GDP g fuel dispenser rew by 2.6%, its fastest annual growth for almost nine years. (Even so, nominal GDP still remains below its level in 1997.) No nominal matter Shrinking nominal GDP created a vicious circle by causing Japan s huge ratio of government-debt-to-GDP to rise further. Rising nominal GDP will now help to reduce that, and by boo fuel dispenser
