    be installed in oil; in some regions and mount areas adopts high bracket tank, to refuel through oil gravity. Under these two situations the inlet oil pressure of fuel dispenser is larger than atmospheric pressure. The latter model adopts volume pump --- often gear pump or vane pump, installing inside of fuel dispenser together with motor. A certain vacuum pressure occurs at the inlet of fuel dispenser when fueling. Fuel dispenser mounted submersible pump, its pump bein fuel dispenser g inside of tank with low noise, has large room to facilitate design many nozzles. The negative pressure fuel dispenser, however, has the benefit of convenient maintenance and low price of whole system. At recent, as negative pressure one prevails in market, the article mainly introduce this kind of fuel dispenser. Negative pressure fuel dispenser normally selects a ration cubage pump. In order to ensure adjusting flow rate there is a bypass valve connected with pump in juxtaposition. When refueling fuel dispenser’s discharge capacity is controlled by the return volume of bypass valve that, of course, ensure the hydraulic system security of fuel dispenser. This kind of bypass valve generally is overflow valve that is closed down while fuel dispenser dot work, and always open as fuelling. The return volume of overflow valve is changed by fuel dispenser’s flowage. Pump is a key component. Its performance is measured through the following aspects: suction capacity, reliability, noise and stability. Of date, some manufacturer put pump and oil-air separator into a common frame, but some install these elements respectively. Some people in circle call pump and oil-air as pump source. Pump’s performance only relate to its structure design and manufacturing level, not the connection of components. The handbook, therefore, introduce by fuel dispenser the category of pump, not by the connection of oil-air separator. Vance pump It is also called rolling broad pump.

    than a century, and its people have been citizens since 1917. They do not vote in national elections or pay federal income taxes, but those are not the biggest differences between Puerto Rican residents and their fellow American citizens. The island is distinguished by its poverty and joblessness, which are far worse than in any of the 50 states. The territory s economy, moreover, has fallen further behind the national one over the past three decades. Bad government—n fuel dispenser ot just locally, but also federally—is largely to blame. Yet most Americans are oblivious to the Caribbean island s problems. The place did earn a rare and brief mention in some mainland newspapers earlier this month. Its government had hit a borrowing limit and partly shut down for a couple of weeks, putting 95,000 civil servants out of work. Then leaders in San Juan—the commonwealth s capital—agreed on a budget deal that let the government borrow more and resume paying people. The drama ended, and life there reverted to its depressing former state. Some Puerto Ricans are doing well. Most of Aguadilla s 70,000 people, for example, live in the richer suburbs that surround the city. The area has many of the same fast-food and retail chains that pervade the United States, and companies from the mainland, such as Hewlett-Packard and Micron Technology, have built factories nearby. Much of the island, however, is like Aguadilla s town centre, full of low incomes and idle hands. Puerto Rico s annual income per person was around $12,000 in 2004, less than half that of Mississippi, the poorest state. More than 48% of the island s people live below the federally defined poverty line. That poverty rate is nearly four times the national average, and more than twice as high as in poor states such as Kentucky, Louisiana, fuel dispenser Mississippi and West Virginia. Half the working-age men in Puerto Rico do not work. Officially, only 46% of those who are not pursuing a degree have formal jobs, compared with a United States average of 76%. T fuel dispenser
