    erally is mounted centrifugal pump installed in tank. The inlet pressure of fuel dispenser with submersible pump is high fuel dispenser er 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 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

    swer to global warming and fossil-fuel dependence; most oppose it as the most dangerous fuel of all. Some think “clean fuel dispenser coal�technology is a potential breakthrough, but West Virginia s Friends of the Mountains has “reservations about a technology that sweeps CO2 under the rug for our descendants to deal with.�There are also rows within organisations—such as the battle within the Sierra Club about whether to oppose immigration on the grounds that greater numbers hurt the environment. Even consensus on principle—such as over the need to promote alternative energy—often breaks down in practice. For instance, to its supporters, a proposal to build 130 giant windmills off Cape Cod will help battle global warming. Robert Kennedy at the NRDC disagrees; the wind farm will be bad for local fishermen, migratory birds and the horizon, and will be “financially feasible only because the federal and state governments have promised $241m in subsidies.�But then other greens claim his motives are not so pure. They say that Mr Kennedy, like his uncle Ted, is interested only in protecting the view from the family compound at Hyannis Port. And so the row blows on, green against green. Mr Kennedy sees the diversity of the environmental movement “as an emblem of its health� He compares it to the civil-rights movement, where Malcolm X and Martin Luther King “seldom co- ordinated efforts as they marched toward a common goal.�Messrs Schellenberger and Nordhaus view the diversity as fatal incoherence, hence their call for environmentalists to unite around the Apollo Alliance, founded three years ago to give the green movement its equivalent of President Kennedy s pledge to send man to the moon. The problem is the alliance s similarity to motherhood and apple pie. Apollo s mission involves investing in technology to create an economy that runs on clean and sustainable energy, creates millions of jobs and demonstrates that a “just, environmentally balanced and economically prospe fuel dispenser fuel dispenser
