the product vary largely and different performance and failure as well. The following just introduce some general methods to solve troubles. 3.1. Inefficient performance The bad separate capacity present as: large foam appears in oil indicator as refueling, accuracy is affected. Maintenance methods and procedure as followed. Firstly to check the nut and plug on strainer whether loose, whether leakage at joint face as stopping operation. If failure is still exists after solve the sealing problem of strainer cover, conduct next progress. Check whether pipeline leakage between tank and fuel dispensers. The check method is to disconnect the end cover of strainer, and to find whether exist oil in low pressure chamber; if no oil or oil level go down slowly, there is some leaking places in pipeline or bottom valve. Inspect exhausting valve seat. Open upper cover and inspect the small hole at exhausting valve seat whether stuck. If the hole is stuck or narrowed by waste, oil indicator would appear much foam due to air leaking into vapor separate chamber. The method to solve trouble is that dredge hole and clean groove, making enough area. Note that the area should don’t too large, large room easily causes leaking oil at exhausting pipe. Check vapor separate chamber. Under normal condition oil level in the chamber should keep a half capacity so that ensure air can’t reach into low pressu fuel dispenser re chamber. (Different products with various oil level). If there is no oil or low level in vapor separate chamber, the tap fuel dispenser er valve would not plug the hole of return oil valve seat, so as air reaching into low pressure chamber via taper valve and returned oil valve. The solution is that inspecting the axis of returned valve and the hole of returned oil valve seat. Reassembling them after solve problems. 3.2. Exhaust pipe leakage When tan fuel dispenser k position is higher than that of fuel dispenser, exhausting pipe will leak oil. Plugging exhausting pipe could solve leakage phenomenon. If found leakage on tank the following procedure

affected their adoption of open-source software. But they probably would be leery if, over time, the code could not be vouched for. In response, big open- source projects such as Linux, Apache and Mozilla have implemented rigid procedures so that they can attest to the origins of the code. In other words, the openness of open source does not necessarily mean it is anonymous. Strikingly, even more monitoring of operations is required in open source than in other sorts of businesses. Openness has been both the making of, and a curse to, Wikipedia. In January 2001 Jimmy Wales s plan for an online encyclopedia written entirely by volunteers over the net was foundering. It was called “Nupedia�and contributions were supposed to go through a rigorous editing process by experts. However, after a year only two dozen articles were in. After Mr Wales and the project s co-ordinator, Larry Sanger, heard about so-called “wiki� software—which makes it easy for people jointly to compose and edit web pages—they changed course. Wikipedia was born and opened to anyone. To welcome the masses, the first entry on its “rules to consider�page was “ignore all rules� People did. Yet two seemingly contradictory things happened chaos reigned, and an encyclopedia emerged. So-called “edit wars�dominated the online discussions, biases were legitimised as “another point of view� and specialists op fuel dispenser enly sneered. Many contributors were driven away by the fractious atmosphere (including Mr Sanger, who went on to pen ess fuel dispenser ays predicting Wikipedia s vulnerability to abuse). Still, the power of decentralised collaboration astounded everyone. After 20 days, the site had over 600 articles; six months later, it had 6,000; by year s end, it totalled 20,000 articles in a plethora of languages (see chart 2). As problems of vandalism, prejud fuel dispenser ice and inaccuracy ensued, Mr Wales was reluctant to clamp down. In the end, he had to. The site has set down policies to mediate debates; it has banished unco-
