operate motor. If it still don’t move or slowly run, electric circuit or motor should be inspected. If not the rotor of pump maybe locked. Carefully check and cleanse oil strainer. If failure still exists after the above inspection, overflow valve should be checkup. In case that valve core jam, shut down incompletely or lose in valve seat the oil in high pressure area overflow into negative area, resulting in no delivery or inefficient discharge. Taking out valve core and spring so as to clean dirty, inspect valve seat at same time. If valve seat is loose re-fix it through oil-resistant glue or change a new pump. When find scrap of spring and graphite, washing overflow valve is must, changing broken parts if necessary. If found rotor is stuck there would be several reasons related, such as spring broken, long vane, vane segment, lose bolts at top cover, etc. reassembling after overcome these reasons. Some manufacturers adopt new spring material evading broken. The lose match of rotor and axis of pump also result in no delivery or inefficient discharge. This situation will be overcome by changing rotor. After the above check and examine still find any rotor stuck or overflow valve abnormal, it is suggestive that vane abrasion is extensive, broken and spring damaged. Much abrasive vane can not successfully segment high and low pressure area, resulting no delivery or inefficient discharge as the areas exchange. The brok fuel dispenser en vane or spring not only cause flow trouble but also increase noise as whole. Furthermore, if they flow into other inner components may result in new failure. The solution to this is to change new vane or spring and clean out broken piece. It is suggestive that change all vanes if fuel dispenser have operated long time.

omy fuelled could put it in conflict with what America regards as a vital strategic interest keeping the Arab world free of nuclear weapons. Over the past 13 years, China has moved from being a net exporter of oil to become the world s second-biggest importer, relying on foreign sources for 40% of its demand. So Iran, which supplies 11% of China s oil imports, might need special consideration. But China s foot-dragging on Iran could be seen as evidence of the same kind of pragmatism that has dominated the country s relationship with America for most of the period since the end of the cold war. China has advocated persisting with diplomatic efforts. Yet in January, when Russia signalled its willingness to allow Iran s nuclear programme to be referred to the United Nations Security Council, China did not attempt to block the move. China is loth to interfere in other countries affairs because it fears that others might use such a move to justify interfering in China s. It would therefore be remarkable if the country were to vote in favour of sanctions. But it would be no less remarkable if it were to veto sanctions on its own. China s military build-up in the next few years will alarm the Americans, particularly as it becomes clear that its forces would be able to overwhelm Taiwan and inflict enormous losses on the Americans if they chose to intervene. But there are very good reasons why China would be highly unl fuel dispenser ikely to attack Taiwan, even if it had the capability to do so. Such an attack would devastate China s relationship with the West as well as with other Asian countries, and could cripple the economic growth that the party regards as so vital. The trouble is that planners in the Pentagon cannot afford to bet on it. fuel dispenser © 2006 .  About spons fuel dispenser orship No time like the present Mar 23rd 2006 From The Economist print edition If China wants to reform, it should act while the economy is booming
