operate motor. If it still don’t move or slowly run, electric circuit or motor should be inspected. If not the rotor of pump maybe locked. Carefully check and cleanse oil strainer. If failure still exists after the above inspection, overflow valve should be checkup. In case that valve core jam, shut down incompletely or lose in valve seat the oil in high pressure area overflow into negative area, resulting in no delivery or inefficient discharge. Taking out valve core and spring so as to clean dirty, inspect valve seat at same time. If valve seat is loose re-fix it through oil-resistant glue or change a new pump. When find scrap of spring and graphite, washing overflow valve is must, changing broken parts if necessary. If found rotor is stuck there would be several reasons related, such as spring broken, long v fuel dispenser ane, vane segment, lose bolts at top cover, etc. reassembling after overcome these reasons. Some manufacturers adopt new spring material evading broken. The lose match of rotor and axis of pump also result in no delivery or inefficient discharge. This situation will be overcome by changing rotor. After the above check and examine still find any rotor stuck or overflow valve abnormal, it is suggestive that vane abrasion is extensive, broken and spring damaged. Much abrasive vane can not successfully segment high and low pressure area, resulting no delivery or inefficient discharge as the areas exchange. The broken van fuel dispenser e or spring not only cause flow trouble but also increase noise as whole. Furthermore, if they flow into other inner components may result in new failure. The solution to this is to change new vane or spring and clean out broken piece. It is suggestive that change all vanes if fuel dispenser have operated long time. Changing a new pump overcomes too large abrasion between frame and rotor. To check wheth fuel dispenser er a leakage occurred in pine between fuel dispenser and tank, different diameter of pipe connection, bottom valve stuck or leakage.

ed out that India, one of the world s biggest economies in 1700, was impoverished by the time the British left. However mixed empire s legacy in India, imperialism has recently provided a rich feast for economists. Their interest lies not just in totting up the balance sheet of colonial rule—although that can be fascinating. They are after even bigger game an explanation of why some countries grow rich and others do not. Of the many proposed solutions to that riddle (technology, geography, the Protestant ethic) the current favourite is rather bland in the abstract “institutions� In rich economies institutions� meaning the formal laws and unwritten rules that govern society—function rather well on the whole. In poor ones they don t. That much is indisputable. What is tricky is showing that good institut fuel dispenser ions are a cause of economic progress rather than a by- product of it. You cannot run controlled experiments in which a particular institution is randomly imposed on some countries, but not on others, in order to compare how they fare. Or at least economists can t. But perhaps imperialists can. Maybe the colonial adventures of the past provide the natural experiments economists need to put their theories to the test. The imperial powers certainly generated a lot of institutional variety, sprinkling Spanish vassalage, British indirect rule and American paternalism across the globe. But was this variation random? Su fuel dispenser rely not. Imperialists vied to plant their flag in the most lucrative spots, wherever the spices were rich or the sugar cane tall. Thus a conundrum remains if, say, America s former colonies have prospered compared with Spain s, was this because America bequeathed the best institutions, or because it found the most promising areas of the world to colonise? What is ingenious about the recent economi fuel dispenser c studies of empire is how they overcome this problem. Imperial institutions may determine prosperity, but the reverse may also be true. The trick is to find some third
