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 pi fuel dispenser peline, 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 fuel dispenser 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── 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 hydrauli fuel dispenser c 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,

h Ali Khamenei, who has the final say on anything important, threatened to block oil from leaving the Persian Gulf if Iran felt, in the course of bargaining, that the sticks outweighed the carrots. “In order to th fuel dispenser reaten Iran, you say you can secure energy flows in the region,�?he told the Americans in a speech at the shrine of his revolutionary predecessor, Ayatollah Ruhollah Khomeini. “Beware if you make the slightest mistake over Iran, the energy flow through this region will be seriously in danger.�? Iran s lead fuel dispenser ers have previously hinted that they could counter UN-endorsed economic sanctions on Iran, which the Americans have often recommended, by stopping their oil exports, in an effort to drive oil prices sky-high and harm all the world s economies. Mr Khamenei s comments immediately lifted crude prices by nearly 80 cents a barrel to more than $73, showing just how fast energy markets twitch at the prospect of Iranian oil curbs. After the Iranians then made more conciliatory noises, the oil price fell back again slightly, but remained near the record level it had reached in April. It would certainly rise even higher if Iran carried out its threat to curtail its own production. It exports about 2.8m barrels a day, some 3% of world demand. Since few producers have much spare capacity at the moment, any reduction in supply—be it from Iran, Nigeria or Bolivia—makes prices jump. Iran s output would be hard to replace —but not impossible. Saudi Arabia says it is fuel dispenser not pumping as much oil as it can, for want of buyers, and so should be able to make up for much of any cut in supplies. Furthermore, the Saudis slackening output suggests that the high price is finally beginning to sap demand. But Mr Khamenei did not just threaten to cut Iran s own supplies—he also implied that oil exports from other Gulf countries might be in jeopardy. Iran had already flexed its muscle in April by holding naval manoeuvres in the narrow Strait of Hormuz, which provides the only outlet from t
