This device often is installed on check valve, hose pipeline also release certain hydraulic pressure. Pipe Resonance Apart from hydraulic stock, other hydraulic components also cause a certain degree of noise in pipeline, such as vane pump, overflow valve, vapor separator, measurement transducer, solenoid valve and nozzle. Sometime pipe resonance will be generated if the inherent frequency of pipe equivalent to hydraulic pulse resulted from hydraulic components of fuel dispenser. At that time, the normal working state will be affected, which is harmful to staff’s health due to intensive noise. In order to explain this problem, the inherent frequency of pipe is introduced here. Pipe inherent frequency is: ω0 = kπ/2 l2 ·EJgGd+Gj (2-14) In the above formula: ω0 ── inherent frequency of pipe l ── supporting point distance E ── elastic modulus of pipe material J ── inertial moment of pipe section g� fuel dispenser �─ acceleration of gravity Gd── weight of pipe per meter Gj──liquid weight in per meter of pipe K── modifying coefficient K= 1-pA+mv/2π2EJA/l2 (2-15) In above formula: A ──pipe section m ──liquid weight in per meter of pipe v ──velocity of flow of liquid in pipe Several relative parameters affect the inherent frequency of pipe in Formula 2-14. Therefore, most manufacturers pay much attention to these elements that affect pipe inherent frequency and pulse frequency of hydraulic components in the design and manufacture of fuel dispenser, making the two frequencies as much different as possible so as to appear pipe resonance in fuel dispenser. 3. Hose used for fuel dispenser There are two kinds of hose used in fuel dispenser. one is made according to GB/T10543 Rubber Hose Used for Refueling and Discharge of Airplane, connected oil indicator with nozzle; the other kind of hose is used in fuel dispenser with vapor recovery device, not only connecting oil indicator with nozzle, fuel dispenser fuel dispenser

explain and return donations. The danger is that, as with the cronyism exposed by Hurricane Katrina, Mr Bush and his lieutenants will claim this as a case of a few bad apples. In fact, the Abramoff affair is a case study of how the conservative movement has gone wrong. Mr Abramoff originally arrived in Washington as one of the young conservative idealists who wanted to shrink government and drain the Washington swamp. He supported Newt Gingrich s crusade to get rid of the ruling Democrats “culture of corruption�? Nowadays, Mr Abramoff, like so many other Gingrich revolutionaries, has been engaged in influence-peddling on an epic scale. Rather than trying to cleanse K Street, the capital s lobbying centre, the Republicans had a “K Street project�?to conservatise the industry. This has produced millions for the Republican Party. But much has been lost in the process. Gone is the enthusiasm on the American right for slimming government. fuel dispenser Under the free-spending Mr Bush, everybody has become a “big- government conservative�? Gone, too, is any enthusiasm for term limits; indeed, most Republicans spend their time trying to gerrymander districts to keep them there for life. And there is little willingness to change. You might have imagined, for instance, that the fury about money going to build two “bridges to nowhere�?in Alaska in the wake of Katrina would have scuttled the projects. But the bridges are going ahead. For the Republican establishment, Mr Abramoff s plea is a final warning to clean house. In Mr Bush s case this means not just purging the White House of cronies (he has less sway in Congress), but also vetoing spending bills. The number of “pork-barrel projects”—ones that get round normal budget rules—increased from 2,000 in 1998 to 14,000 last year. The political cost of inaction could be high. Most Americans long ago made up their mind on the Iraq war and they actually agree with Mr Bush on the wiretapping fuss. But there is no surer way of losing electio fuel dispenser fuel dispenser
