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 sett fuel dispenser ing 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. Noise Noise is also a 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 pump of fuel fuel dispenser 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 fuel dispenser 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

the president s. “We want a president for the Yemenis instead of Yemenis for the president,�declared Mr bin Shamlan repeatedly, “We don t want a change of personnel, but a change from personal rule to th fuel dispenser e rule of institutions.� The potential for violence is never far from the surface in a country whose 20m citizens are estimated to own some 60m firearms. Hoping to pre-empt trouble, state television mounted a campaign promoting peaceful voting, and the army deployed in force near polling stations. On voting day, megaphones reminded citizens that guns, commonly carried in rural regions, were to be left at home. As if to emphasise the danger, the week before voting was marred by two near-simultaneous terrorist attacks against important oil installations. Luckily, the four suicide bombers, assumed to be linked to al- Qaeda, blew themselves up when confronted by security officers. The police announced the pre-emptive arrest of four other suspected terrorists. These successes form part of a trend that has seen a general waning of the influence that al-Qaeda and its offshoots have in a country that, until five years ago, housed more than a dozen jihadist training camps. The continuing saga of four French tourists, captured by tribesmen and held hostage for the past three weeks in a bid to extract concessions from the government, mi fuel dispenser ght seem to mar the generally improving security picture. But such snatches are a form of traditional tribal bargaining, and tend to end peacefully. Obviously, such antics do little to promote investment. It is desperately needed. The World Ba fuel dispenser nk estimates that 42% of Yemenis live below the poverty line. Economic growth in recent years has not matched population growth, which still runs at more than 3% a year. Oil exports, which now produce 70% of state revenue, are set to decline as reserves dwindle, with some experts predicting they may run out as soon as 2012. Given such burdens, it is not surprising that so many Yemenis wearily admit that Mr Saleh m
