causing noise and abnormal vibration is many, either because of fuel dispenser�or exterior elements (pipe trouble). Therefore, it is first to exclude exterior reason of fuel dispenser, then interior one when overcome the above situation. After that, examine strainer and fuel dispenser clean dirty. Next parts being checked is overflow valve. Tight spring will stick valve core and generate large noise and vibration. In addition, don’t pursue large flow rate through adjusting spring extensively, since that will shorten the service life of fuel dispenser due to large system pressure. If noise is still large after the above maintenance, pump should be disassembled so as to examine vane and spring whether broken. If these parts are broken the outlet flow fluctuation of pump would be enhanced, as well as noise and vibration. The solution method is to change a new vane and spring. Leakage Leakage is divided as two categories, namely, inner leakage and outer leakage. Under the high oil pressure in hydraulic system oil is leak from high pressure area to low area, which is called inner leakage. The abrasion of vane, rotor and frame result in extensive inner leakage so as to reduce delivery volume of fuel dispenser. The outer leakage is the one oil leak from inner hydraulic system into outer, which increase unsafe environmental elements except from affecting the normal working performance of pump. To change a new oil se fuel dispenser al when find a leakage coming from the root of pump axis. Be sure that don’t make a mi fuel dispenser stake in installing oil seal. Diagram 2-7 show the correct position ----- the labium of oil seal should face to inner chamber. In addition, tight V wheel also hurts the surface of oil seal next to pump axis so that its capacity is invalid. Diagram 2-7 The most leaking sections are the connecting face---- between pump cover and pump frame, between pump frame and vapor separator, place of cap nut of overflow valve. All of reasons are damaged seal loop or seal gasket, thus change new sealed components as soon as quickly.

bunch of flowers, a teddy bear and an empty Chivas Regal bottle—in memory of a young murder victim� lie on the street outside the DC Preparatory Academy. This patch of north-east Washington, DC, is not an easy place to live, let alone run a school. fuel dispenser Yet the school itself is an oasis of order. Blue-uniformed nine-year-olds look visitors straight in the eye and proffer handshakes. In one class, a sixth-grader called Prince Taylor solves a ticklish maths problem on the overhead projector. His teacher, Julie O Malley, asks him to explain how he did it. He starts, but she cuts him off because a couple of his classmates are not looking at him. “Remember the rule,�says Ms O Malley. All eyes focus on Prince, who resumes his explanation. Schools in the rougher parts of Washington have long been among America s worst. DC Prep shows they needn t be. Its pupils are all from an ethnic minority, mostly black. Its budget per head is no more than that of other local public schools. It does not select entrants by academic ability. And yet in 2003-04, its first year of operation, its pupils advanced on average 1.7 “grade equivalents�in reading (ie, they learned as much in one year as a child is expected to learn in 1.7 years) and 2.3 in maths. The secret? Nothing fancy just getting the basics right. As a fuel dispenser charter school, publicly-funded but free of bureaucratic control, it can shun tre fuel dispenser ndy educational theories in favour of discipline, phonics and longer school hours. Charter schools now educate over a fifth of the students in DC, up from none in 1996. Washington s mayor, Anthony Williams, has championed the experiment, a stance that has not always made him popular with his fellow- Democrats. “Parents should decide,�he says, adding that competition from charter schools should “force the regular public school bureaucracy to change.� M
