    ection is small, pump suction is large; vice versa, large returned oil low suction distance. Diagram 2-5: Suction flow of vane pump Suction capacity of pump is restricted not o fuel dispenser nly by its structure but also by the oil physical trait and pipeline. Under a certain temperature, air pocket phenomenon of oil will generated when vacuum reaching a given degree, so that the pump can’t suck oil normally. At high oil level, large resistance from pipeline, much higher vacuum pressure occurs at the inlet of pump; the higher temperature the more likely create air pocket. The phenomenon is likely to appear given the oil is gasoline. The phenomenon of cavitation is generated when partial pressure at inlet of pump is low than air pressure, the dissolved gas in oil begin separate out, and oil start gasifying vigorously as pressure getting down, reaching saturation pressure. The normal working of pump is affected due to a great of foam damaging the continuity of liquid flow. Fuel dispenser is likely come out any oil or work with large noise as the cavitation is severe. Components will be damaged in this long phenomenon. At same time, oil vibration is increased so that the accuracy become down, as well as shorting service life of hydraulic components. The correlation between liquid saturation and gas pressure is illustrated in diagram 2-6. Diagram 2-6: Relations among temperature, steam pressure and liquid saturation Diagram 2-6 shows gasoline more likely to Air area than water and coal oil under the same pressure along with temperature increasing; under the same temperature the more vacuum pressure the earlier in air-area. There are two aspects that should be considered to prevent cavitation in pump inlet. One is that the design parameter of pump should be rational. The other is that pipeline should be installed scientifically. The effect of hydraulic pipe to fuel dispenser’s suction capacity will be introduced in detail. To understand the principle of cavitation and causation of affecting pump suction capacity is fuel dispenser fuel dispenser

But Egypt s initiati fuel dispenser ve was meant to send a message in another direction, too. Like other Arab states, it has grown impatient over the West s perceived double standards regarding Israel s monopoly of nuclear weapons in the region. At a little-reported session of the International Atomic Energy Agency last week, America and its allies joined together to block an Arab-Iranian resolution calling for Israel to join the NPT, and for the Middle East to be declared a nuclear-free zone. Egypt s foreign minister, Ahmed Abul Gheit, riposted “For developing and Arab countries to comprehend the concern Western powers express over the Iranian nuclear issue, these Western powers have to convince everyone that they adhere to all that is lawful, and not pick sides.? © 2006 . About sponsorship Tanzania Bye-bye poverty Sep 28th 2006 | DAR ES SALAAM From The Economist print edition An African country that deserves the money it gets DEVELOPMENT economists use it as a measure. If Tanzania can haul itself out of poverty, others can too. But if it cannot, there will have to be another rethink about the way that aid money is spent. For the moment, Tanzania is one of east Africa s few good-news stories. That isn t saying much. The country remains wretchedly poor, inefficient, with little medical care in its remote areas, few roads and with frequent power cuts, even in Dar es Salaam, the largest city. But donors, disillusioned by the corruption and or brutality that goes on elsewhere, are happy to pour money into somewhere that is, at least, both peaceful and stable. And in Jakaya Kikwete, Tanzania has found a president committed to doing his best to cut poverty. A long-serving former foreign minister, Mr Kikwete was elected in December with 80% of the vote.
