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 dia fuel dispenser gram 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 fuel dispenser 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 fuel dispenser 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

atrician, points out that youngsters, many of them barely in their teens, are already having sex and that, not surprisingly, many of them are getting pregnant. According to a 2003 survey, around 15% of all babies in Chile are born to teenage mothers. The proportion ranges from 22% in the poor fuel dispenser est neighbourhood of Santiago to just 1% in the richest. The centre-left coalition, which has governed Chile since 1990, is partly to blame for that glaring difference. For several years now, the private health services, used by better-off Chileans, have been prescribing the morning-after pill to teenagers even without their parents consent, while the national health service, catering for poorer Chileans, is still restricting its use to rape victims. In defiance of the solidly Catholic fuel dispenser Christian Democrat party, the ruling coalition s biggest partner, Ms Bachelet, who is herself an agnostic socialist, has now decided that the national health service should prescribe the morning-after pill to anyone over the age of 14, the legal age of consent, who wants it. In response to protests by horrified parents and opposition politicians, the Santiago Appeals Court issued a temporary injunction on September 13th banning the national health service from prescribing the pill to anyone aged under 19 without their parents consent. But doctors argue that, if parents have a say, teenagers may be put off going to health clinics and end up seeking an illegal and risky backstreet abortion instead. Dr Barría s announcement raised a predictable outcry among conservative opposition politicians and the Catholic Church. The plan “recalls the public policies of totalitarian regimes that wanted to impose state regulation on people s intima fuel dispenser te lives,�thundered the Church. Ms Bachelet insisted that she was not seeking to impose her beliefs on anyone; she was merely offering alternatives. And that, rather than easier access to contraception, is why so many young Chileans are jubilant. For them, the government s morning
