ispenser is operated simply, putting down nozzle to start system, and nozzle automatically closed when tank is full. Other operation can be conducted on the operating keyboard, such as presetting, starting, close, inquiry and various denotations. Main components and functions Main components A fuel dispenser composed of pump, oil-air separator, flow meter (measurement transducer and counter display part), nozzle, electric system (control, transmission, operation, and display system), electric section, pipeline, oil indicator, bracket, covering, etc. Need to special explanation that f fuel dispenser uel dispenser is a kind of delivery equipment used in flammable and combustible circumstance, thus, the electric fuel dispenser and electrical components and their connection should be manufactured and certificated in conformance with the national explosion-proof standards so as to ensure the product security. In addition, China had stipulated that from February, 1990 that the commercial fuel dispenser should have the function of tax-supervision, in accordance with the national taxation requirement so as to safeguard the reliability and security of taxation data. The key components and main principle of fuel dispenser as followed: 1-Motor 2-Pump 3-Vappor separator 4-Measurement transducer 5-Sensor 6-Mechanicle/electronic counter device 7-Oil indicator 8-Nozzle Diagram 1- 20: Major components and working flow of fuel dispenser 2.2 Main components functions When the fuel dispenser’s starting component work (e.g. take off nozzle or push starting button) motor is operated and drive pump. fuel dispenser The oil is sucked into pump chamber from underground tank, being be pressured in pump body, and flow into oil-air separator in where air was segregated from oil. The air-free oil flow into measurement transducer and impel the calculating piston move, the position movement of output axis sign corresponding to fuel filled was transmitted and converted into electric pulse sign through sensor. The pulse sign transmit to electrical counter device that r

einforcing Afghanistan AP A meeting of NATO at Mons, in Belgium, failed to produce offers of fresh troops to reinforce the security force in Afghanistan. Condoleezza Rice, America s secretary of state, had given warning that Afghanistan risked becoming a dangerous failed state, a markedly more downbeat assessment than before. Poland later offered to send 1,000 extra troops to Afghanistan, but not until February. Police in India said they were exploring the possibility of a lin fuel dispenser k between last week s bomb attacks in the western town of Malegaon, which killed 32 people, and July s bombing fuel dispenser s in Mumbai. The latest attacks came before this week s expected meeting in Havana, Cuba, between India s prime minister, Manmohan Singh, and Pakistan s president, Pervez Musharraf. See article China announced a new, more restrictive system of controls on the reporting of court cases. Leaks from anyone other than authorised spokesmen will be punished. The echo of a dirty war Ubiratan Guimarães, Brazil s former chief of police, who was held responsible for the deaths of 111 prisoners in a riot in a São Paulo jail in 1992, was found shot dead at his home. Although the target of frequent death threats, police believe his murder to have been a crime of passion. See article An American court ruled that Luis Posada Carriles, a Cuban former CIA agent, should be released from an immigration centre. He is wanted by Cuba and Venezuela in connection with the 1 fuel dispenser 976 bombing of a Cuban plane that killed 73 people and a plot to kill Fidel Castro. The Americans refuse to deport him, believing he could be tortured. Making up Hamas, which runs the Palestinian Authority, and Fatah, which used to, agreed to form a national unity government. Ismail Haniyeh, a Hamas leader, is expected to stay on as prime minister. Mahmoud Abbas, the Palestinian president, will be in charge of negotiations with Israel.
