than 1000L/min. The manufacturers of submersible pump now have many in market not only home brand but exported brand. As their structure and performance vary largely, the handbook will not introduce them one by one. Some failure and trouble occurred during operation should be solved in accordance with the maintenance explanation provided by manufacturer. In order to ensure operation security difficult problem occurred should be inspected and repaired by the professional technician experienced or maintenance artificer sent by manufacturer in case of bringing accident. Article II Vapor Separator The main function of vapor separator is segregated vapor from oil and discharge so as to ensure accuracy of measure transducer under no foam condition. The principal technical indicator guideline of vapor separator is the capacity to segregate vapor and keep stability. 1-Upper cover 2-Exhaust valve seat fuel dispenser 3-Exhaust pipe 4-Float 5-Fuel return valve 6-Frame 7-Ball-float 8-Strainer 9-Spring seat 10-Check valve 11-Check valve seat 12\13-Outlet pipe 14-Gas outlet valve Diagram 2-12: Structure cutaway view of vapor separator Check valve should be installed between vapor separator and measure transducer. Some manufacturers mount check valve in the pipeline of vapor separator and transducer, but others install check valve in the inner of vapor separator. Check valve has the function of preventing oil flow backward. The segregated capacity is the major technical parameter of vapor separator. Under low pressure and high temperature a little of gas dissolved in oil is easily separated out. The vapor should be divided out before flow fuel dispenser ing into measure transducer so as to keep the accuracy of fuel dispenser in the scope stipulated by national standards. Stability is another key parameter of vapor separator. In case that the design and manufacture sector of pump and vapor separator exist unstable elements, the pressure pulse fluctuation of fuel dispenser’s hydraulic system will increase, even affecting the measur fuel dispenser

side (mainly by Americans), told with candour, humour and insight. Compared with the mainly Sunni Arab provinces north and west of Baghdad, Mr Stewart s mainly Shia area in Maysan was mild. But he makes it plain, without wringing his hands or denigrating the locals, that the culture of violence along with tribal and religious intrigue make it unthinkable for Western democratic values to take root any time soon. He sought to appoint provincial councils, governors and police chiefs, but most of his constituents had no concept of democratic procedure. “If they make any trouble,� explained one leading politician of a rival group, “we together will kill them.�“If you put my cousin on the provincial council,�explained another local bigwig, “I will slit his throat.�“Seyyid Rory, you don t understand,�complained another. “How do you make a prisoner talk if you don t torture him?�Though in no way f fuel dispenser lippant or sneering, Mr Stewart makes it plain that the neo-conservative agenda in such areas is absurd. Messrs Stewart and Ajami make glum reading. By contrast, a slim volume by one of Britain s leading diplomatic Arabists, Mark Allen, is an amiable and in many ways more useful guide. Knighted for—among other things—his apparently key part in persuading Libya s Muammar Qaddafi to give up his programme to build nuclear weapons, Sir Mark, a long-serving member of MI6, Britain s external intelligence service, offers a thoughtful potpourri of observations on the Arab psyche and identity. Acknowledging that “a systematic technique for dealing with contradictions and dissent�is woefully lacking in the Arab world, he also str fuel dispenser esses that the old-fashioned bonds of blood, tribe, religion and pan-Arab identity tend to govern behaviour and can, if subtly addressed, be woven to good effect. Politics is still necessarily personal and clan-based; antipathy to fitnah (social discord and strife) makes it hard to envisage a peaceful institutionalisation of adversarial politics.
