conducive to the failure that no oil is sucked. Don’t worry about the phenomenon of cavitation because its probability to occur is low, and the method to prevent it appearance would find when pipeline setting and the design and manufacture of pump. At present, manufacturers have achieved great progress in research to prevent cavitation in pump inlet. The phenomenon is avoidable. Stability The stability of pump is more important technical parameter, which is one of major labels measuring the performance of pump. The good stability of pump is low fluctuation in flow and slow increase of pulsant value as working long time. The 13.6 of JJG667-97 Liquid cubage flow meter stipulates that the flow rate fluctuation not exceed 2.5%, which is requirement for pump stability. Under same operating condition a good stability pump reduce the abrasion of hydraulic components so as to lengthen fuel dispenser’s service life. Moreover, it is conducive to reduce leakage of measure transducer and enhance the accuracy fuel dispenser . Noise Noise is also a fuel dispenser symbol of pump’s performance, which relate to fuel dispenser’s noise. The GB/T9081-2001 Fuel dispenser for vehicle stipulates that the noise of fuel dispenser not exceed 80d B and the noise of pump no more than that of fuel dispenser, which is basic requirement for fuel dispenser. Noise is often created from fuel dispenser pump of fuel dispenser, computerized fuel dispenser in particular. The pump noise is largely depended upon its stability, cavitation, partial flow speed and oil abrasion, etc. High noise pollutes environment and wastes electricity so as to increase operation cost of filling station. Usage and maintenance Many domestic component manufacturers now produce vane pump, but their products vary from inner structure, choice of material, suction capacity, stability, service life, noise and so on. Thus failure presents largely different. Vane pump should often be inspected and maintained during the operation progress. Specific procedure is as followed: Often inspect the rotati

. Furthermore, it is a way to defend generous support for the poor—as long as they find work. Another attraction for developed countries as their populations age is that it mobilises more employment to maintain living standards and help pay for the old. And, best of all, it works. © 2006 .  About sponsorship The Democratic Republic of Congo Mending Africa s broken heart Jul 27th 2006 From The Economist print edition The best chance for a generation, unless the world walks away AFP THE Democratic Republic of Congo has been lots of things—impoverished, divided, blood-stained and tyrannised—but never democratic. Plundered for decades by one of the continent s cruellest and most rapacious dictators, President Mobutu Sese Seko, it has been torn apart by civil war since his regime collapsed in 1997. Almost 4m people are reckoned t fuel dispenser o have died—more than in an fuel dispenser y other conflict since the second world war. The term “failed state�could have been invented to describe the place. So the country s first free and fair presidential and parliamentary elections, due on July 30th, will be a landmark (see article). The prospect of the vote has raised expectations among Co fuel dispenser ngolese that their country is at last on the road to recovery. Since a peace agreement was implemented in 2002 between the government and various warring parties, unprecedented efforts have been made at home and abroad to keep the peace and create a rudimentary infrastructure for the election. Registering nearly 26m voters and setting up 53,000 voting stations in a country the size of western Europe, with no good roads in the whole place, has been the most complicated and expensive electoral-assistance mission ever undertaken by the United Nations. And the 17,600-strong peacekeeping force in Congo is the largest the United Nations has ever put together. Congo s
