    . Presetting refuel and non-presetting refuel Fuel dispenser’s hose is full of oil in non-presetting refueling fuel dispenser progress. Due to the function of solenoid valve in presetting refuel progress, hose is not full as that of non-presetting. Only one refuel mode is adapted in appraisal progress because hose cubage directly affect accuracy of fuel dispenser. Oil Volatility The working media of fuel dispenser always is volatile, vehicle gasoline in particular. Oil volatilization inevitably affect the appraisal result, therefore, it is prohibited to conduct test in large wind or high temperature whether. Chapter VII Failure and Troubleshooting Like any other machinery, fuel dispenser u fuel dispenser navoidably appears failure during long time of operation. it is not a simple thing in maintenance progress as judge the trouble part or reason. Since fuel dispenser is composed of varied mechanical, electronic and hydraulic components, a failure maybe caused by diverse reasons or a same reason result in different trouble. In addition, fuel dispenser operates with other exterior devices --- outside power network, tank, delivery pipeline, etc, which also generating abnormal working -- rather than independently. Therefore, fuel dispenser’s functional failure is just phenomenon, mechanical failure is root reason. Only know working principle and structure firstly, can repairer correctly judge failure reason and solve trouble. In order to do that the academic knowledge is needed to support, to learn the relation between causation and phenomenon, and ceaselessly summarize practical experience. In short, as for fuel dispenser’s failure, preventive guideline and strict safety operation regulation, should be carried out, enforcing regulative maintenance and inspection, getting rid of trouble within burgeon state. Owing to various models and structure in domestic fuel dispense market, specific type should be maintained in accordance with the User’s Manual, the handbook only presents the common failure and troubleshooting of genera fuel dispenser

    cobble them together? Of course not, the critic would concede; one buys a whole car. So Mr McNealy won his argumen fuel dispenser ts—but lost his customers, who had come to the conclusion that computers were in fact nothing like cars. Gradually, Mr McNealy came around to the new way of doing things. Always a good sport, he mounted a stage in 2002, dressed as a penguin (the mascot of Linux) to announce that he would offer Linux on Sun servers. He struck a deal with AMD, a chipmaker that is the main rival to Intel, so that Sun could supply computers built around AMD s chips in addition to its own Sparc chips. Mr McNealy bought a company—which had been started by Andy Bechtolsheim, another of Sun s fuel dispenser four founders—that made computers based on industry standards, the antithesis of Sun s approach. He bought a large data-storage company, too. So little time, so many stages To his chagrin, none of these moves won over his critics. So, more stages were mounted. Mr McNealy hugged and swapped hockey jerseys with Steve Ballmer, the boss of Microsoft, a firm he had always loved to hate. He got up on a stage with Eric Schmidt, who used to work for Sun, but is now chief executive of Google, a much sexier technology company that fascinates the press� but it turned out that the two men had nothing in particular to announce. Mr McNealy then made two gestures that he considers shockingly bold. Last year he made Sun s operating system, Solaris, open-source, so that—as with Linux—anybody can in theory use it free (though in practice, customers usually pay service fees for maintenance). Earlier this year Sun went one better and also made the design of its Sparc chip open-source—a rare example of open- source extending to hardware. Surely these two actions proved that Mr McNealy not only preaches the “economics of sharing�but practises it, too? Unfortunately, none of this visionary stuff seems to be helping Sun. All the changes Mr McNealy has made since 2002 have been attempts to convince custome fuel dispenser
