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 ── suppo fuel dispenser rting 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 fuel dispenser 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 r fuel dispenser esonance 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 consumer spending, which rose at an annual rate of 2.8%, looked healthier than for a good while. Overall growth was held down by sluggish construction, the result of bad weather, but this promises to rebound in the second quarter. Economists at JPMorgan now think that GDP could grow at a rate of 3% this quarter, and an average of 2.8% in the second half of the year. A recent wave of cheery economic news supports this forecast; indeed, the economy could even surpass it. Business and consumer confidence surveys are roaring ahead. The durability of the recovery will largely depend on whether firms start hiring again. Here the news is promising. Unemployment has fallen by more than expected in both France and Germany in recent months. Germany s jobless rate has fallen from 11.9% to 11% during the past year, and France s from 10.1% fuel dispenser to 9.3%. These rates are still shamefully high, but it is the change in unemployment rather than its level that matters most for shifts in consumer spending. More good news could be in store. Going by the hiring intentions reported in the euro area s purchasing managers index, JPMorgan s David Mackie reckons that employment is growing at an annualised rate of almost 2%, more than twice as fast as last year, and the fastest since 2001. New jobs, rising consumer confidence (which is at a five-year high) and, in some countries, surging hous fuel dispenser e prices (see article) should encourage households to open their wallets. Indeed, euro-zone retail sales rose by a faster- than-expected 2.8% in the year to April. Even German consumer spending is picking up, helped by the World Cup. St fuel dispenser ronger growth allows the ECB to focus more intently on its inflation target namely, holding inflation close to, but below, 2%. The average inflation rate in the euro area rose to 2.5% in May, which was higher than expected, and the European Commission s latest survey showed that inflation expectations are edging up. The IMF warned the ECB this week against raising interest rates too fast.
