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 comp fuel dispenser osed 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 standard type access to general requirements, but the enhanced type not only increase flux than standard type, but also available to mix 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 frequency 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 fuel dispenser fuel dispenser

to buy cars with diesel engines, which are usually more efficient than Otto-cycle engines. However, the fashion did not last. Diesels disappeared from American cars in the 1980s because they were dirty, dull and unreliable. Two things, however, are reviving interest in them. One is the appearance of cleaner, low-sulphur fuel. This is already commonplace in Japan and Europe, a fuel dispenser nd will be introduced to America in the autumn. It contains a mere 15 parts per million of sulphur, which is less than a thirtieth of the amount tolerated today. Coupled with recent advances in direct injection (“common rail� engines that improve combustion, and durable particulate traps to capture tiny but dangerous particles of soot, this new fuel is cleaning up emissions and transforming the prospects for diesels in America. J.D. Power, a market research firm, forecasts that the share of the market taken by diesel cars will quadruple from today s 3.2% by 2015. At the motor show, Mercedes-Benz, Honda, BMW, Nissan and Chrysler all revealed their intentions to make diesel engines available in their American cars. Volkswagen, which sold about 30,000 diesels in America last year, says it could have flogged twice that number if it had anticipated the rise in demand. Mercedes is promoting its new BLUETEC system—which incorporates oxidising catalytic converters, particulate filters and a new nitrogen-oxide- reducing system that injects the fuel with urea. This chemical grabs oxygen atoms from nitrogen oxides to produce nitrogen gas (which is harmless) and water. BLUETEC will thus meet new, tougher federal rules on nitrogen-oxide pollution that come into force in 2009. Mercedes claims the new diesel engines it intends to put on the American market will also be 20-40% more economical than their petrol equivalents. It quotes estimates by the Department of Energy which say that if only one-third of America s cars and light trucks were diesels, this would save a quantity of oil equivalent to the country s imports fro fuel dispenser fuel dispenser
