. Examine clearance and replace relevant components when necessary. 1.4. Measurement transducer block 1.5. No discharge due to Solenoid valve clo fuel dispenser sed. First check electric wiring, then trouble on component itself (short circuit of winding or block in valve membrane, etc). 1.6. Pipeline and bottom valve failure If continuously exhaust in vapor separator from beginning, disconnect filter cover and take out filter net; pour same kind of oil in it and given see oil level quickly drop, there is leakage occurred in pipeline and bottom valve. 1.7. No discharge caused by nozzle failure Jam in jointer or filter. Unlock strainer or jointer to remove dirt and waste. Nozzle always in auto-shut state, check automatic shut device, mainly inlet vent, spring. 1.8. Bottom valve be stuck in and pipeline is plugged. Exterior reasons for no delivery Oil level is so lower than bottom valve that pump c fuel dispenser an’t suck oil. Some valve(s) is closed in pipeline between tank and fuel dispensers. Air goes into valve(s). Single phase valve is rusted in bottom valve. Incorrect installation of flange causes leakage between inlet pipe and fuel dispenser. Inappropriate oil is refueled. Oil is easy to gasify; water in oil freeze; wax in oil plug pipe. Pipe design is unsuitable. Two fuel dispensers, for example, are connected in same pipeline without valve, or valve can’t shut completely; pipeline has many crooks or too thin. Slow flow rate as starting 3.1. Strainers, including cone-shaped filter net and nozzle filter net, are jammed. 3.2. Large amount of air flow into from broken parts or pipeline, causing much foam in oil indicator. 3.3. Large noise and vibration during operation Vacuum pressure is inadequate. Leakage occurs in overflow valve or pump gasket. Inner leakage in fuel dispenser increase as serious abrasion in pump vane or vane is stuck by waste. Vapor separator trouble Small floater of vapor separator is broken or fall down; insufficient pressure in high pressure chamber as exhausting valve can fuel dispenser

ress rehearsals, including his first book, “The Elusive Quest for Growth� and a fiery exchange in the Washington Post with Jeffrey Sachs, a bold v fuel dispenser isionary at Columbia University s Earth Institute. Mr Sachs was picked by the United Nations almost five years ago to head a team of over 250 experts, which identified 449 aid interventions in Penguin Press; 417 pursuit of eight Millennium Development Goals. Mr Easterly thinks that this pages; $27.95 approach to helping the poor is seductive but dangerously wrong-headed. Buy it at Amazon.com Visionaries, such as Mr Sachs, want to abolish pov fuel dispenser erty. With that as their goal, Amazon.co.uk they then ask “what does the end of poverty require of foreign aid?�But this is to put the question backwards, insists Mr Easterly. The right question is “What can foreign aid do for the poor?�It is fine, he says, to aim to win the Kentucky Derby if you own a racehorse. But the aid industry is not a thoroughbred. It is more like a milk cow. Poverty campaigners should ask themselves what this set of bovine agencies and institutions can actually accomplish, and see that it gets done. Compassion is not enough to guide these efforts, Mr Easterly says. Donors must also be answerable to the people they claim to help. The Samaritan should not cross the road unless the injured traveller by the wayside can hold him to account for dressing his wounds and providing a roof for the night. Otherwise donors offer what they want to give, not what the poor can use, and they have little incentive to follow through on any charitable gesture they might make. The market prov fuel dispenser
