motor and solenoid valve, with larger power. it also have the type of double-nozzle fuel dispenser mounted with total two sets of system, however, most manufacturers don’t install this type in order to reduce cost. With more than four nozzles, this fuel dispenser is able to be regarded as multi-nozzle type. At recent, mos fuel dispenser t of multi-nozzle fuel dispensers made by domestic manufacturers are rebuilt from double fuel dispenser, which actually mounted two pieces of double fuel dispensers to one frame, in the same way 3 piece to six-nozzle. Therefore, learning the structure of double fuel dispenser is able to know multi-nozzle type. Here main introduce the double-nozzle fuel dispenser. Measuring main board is the core in fuel dispenser’s electric control system, which is reason why some people called this kind as ‘computer fuel dispenser� These operation including starting or stop, calculation, count, data generation and dialogue with machine also are conducted under the control of measuring main board. Display screen, keyboard and fuel dispenser’s switch are the main interface between operator and machine. The staff’s control command to fuel dispenser is mainly conducted through keyboard and nozzle switch, but report information and data are showed in display screen. The function of flow pulse converter, widely called as sensor, is to convert influx into electric pulse so that measuring main board process data. Motor is momentum of rotation of pump; solenoid valve used for presetting filling; power supply board is resource of electric system, which is used for converting alternative current into stable and clean directive current fuel dispenser needed. 2.

Since this “executive force�in its distinctive uniform—green camouflage trousers and black T-shirts under combat webbing� appeared on Gaza s streets, there have been several shootings and killings, played up in fuel dispenser the media as Fatah- Hamas clashes. But locals of all political stripes tend to blame a small and mysterious group of provocateurs that they suspect are from preventive security, the small force that Mr Abu Shbak used to command. Some in Fatah believe that others in Fatah are stirring up trouble in order to put the heat on Hamas. Whatever the truth, the executive force has won Hamas a small public-relations victory. Many of the dozen or so other PA forces, anxious not to look asleep on the job, have deployed too, so that armed men in a panoply of uniforms now stand on the busiest street corners—often alongside members of Hamas s force, chatting happily. Some Gazans are delighted, such as the owner of a busy mobile-phone store who used to take his wares home each night but now has free 24-hour security. Round one, then, to Hamas. But Mr Abbas s ultimatum takes the fight back off the streets and into the political arena. It puts Hamas in a bind, and exposes differences among its multi-headed leadership—the prisoners who signed the proposal, the bosses in Damascus who look dead against it, and the government in the West Bank and Gaza, which seems torn. Hamas members have been publicly trying out various arguments against the referendum it is legally dubious; it is expensive when the PA cannot even pay salaries; it is irrelevant because it hardly differs from Hamas s stance, or because the election was just a few months ago, or because Israel, though busy planning a unilateral withdrawal from much of the West Bank, has no intention of retreating all the way to the pre-1967 border fuel dispenser s anyway. So far, none has really stuck. If the referendum happens and the Palestinians fuel dispenser
