    erally is mounted centrifugal pump installed in tank. The inlet pressure of fuel dispenser with submersible pump is higher than atmospheric pressure. Submersible pump consists of pump, connecting pipeline and controller. The appearance of submersible pump and its position in tank is showed in diagram 2-10. Diagram 2-10: Submersible pump position and figure Submersible pump is composed of motor and centrifugal pump. Pump motor includes electromotor, wiring panel, overheat protector and pipeline; centrifugal pump has the elements of filter, anti-static subassembly, impeller and pump axis. Diagram 2-11: Main structure of submersible pump Connecting pipeline has two types of fixed and stretched. The former type consists of oil pipe, vapor-recovery pipe, lead pipe and wire. The later type is formed by oil pipe, vapor-recovery pipe, adjusting nut, lead pipe and motor wire. Controller is divided as two parts, upper and lower. Upper part have these components junction box, electric bridge, capacitor, exhausting plug, check valve, pressure adjustor, testing interface of exhaustion and pressure, leakage monitor of pipe. However, lower part is constituted by pipe jointer, lead terminals, pump holder, etc. By function, submersible pump is classified as four categories, namely, standard type, enhanced type, changing-frequency type and large flow type. The standar fuel dispenser d type access to general requirements, but the enhanced type not only increase flux than standard type, but also available to mix fuel dispenser liquid of gasoline with alcohol. The changing- frequency submersible pump adopt pipe pressure to judge flux. Given a situation in inefficient flux and low pressure the electric frequency of motor would tune high through computer, so as to elevate rotate speed and increase flux. Contrarily, to reduce electric fre fuel dispenser quency and rotate speed as pipe pressure being low, adjusting appropriate flowage. The large flow type is adapted in filing station in where needs quickly operation. Some submersible pump has the flow speed of more

    ve to pay back the money. Nor are the current arrangements in the long-term interest of America s economy. By buying dollar assets, Asian central banks are subsidising American consumers, encouraging too little saving, too much spending and excessive investment in housing. Asia s central banks have turned off the usual market signal of rising bond yields which should be telling America to put its house in order. As long as America can get cheap money from abroad, it has little incentive to rebalance its economy. When global imbalances are eventually unwound, the process will hurt even more. Unless America reduces its deficit before emerging economies lose interest in accumulating reserves, the dollar, Treasury bonds and the whole American economy are likely to suffer a hard landing. © 2006 .
