causing noise and abnormal vibration is many, either because of fuel dispenser�or exterior elements (pipe trouble). Therefore, it is first to exclude exterior reason of fuel dispenser, then interior one wh fuel dispenser en overcome the above situation. After that, examine strainer and clean dirty. Next parts being checked is overflow valve. Tight spring will stick valve core and generate large noise and vibration. In addition, don’t pursue large flow rate through adjusting spring extensively, since that will shorten the service life of fuel dispenser due to large system pressure. If noise is still large after the above maintenance, pump should be disassembled so as to examine vane and spring whether broken. If these parts are broken the outlet flow fluctuation of pump would be enhanced, as well as noise and vibration. The solution method is to change a new vane and spring. Leakage Leakage is divided as two categories, namely, inner leakage and outer leakage. Under the high oil pressure in hydraulic system oil is leak from high pressure area to low area, which is called inner leakage. The abrasion of vane, rotor and frame result in extensive inner leakage so as to reduce delivery volume of fuel dispenser. The outer leakage is the one oil leak from inner hydraulic system into outer, which increase unsafe environmental elements except from affecting the normal working performance of pump. To change a new oil seal when find a leakage coming from the root of pump axis. Be sure that don’t make a mistake in installing oil seal. Diagram 2-7 show the correct position ----- the labium of oil seal should face to inner chamber. In addition, tight V wheel also hurts the surface of oil seal fuel dispenser next to pump axis so that its capacity is invalid. Diagram 2-7 The most leaking sections are the connecting face---- between pump cover and pump frame, between pump frame and vapor separator, place of cap nut of overflow valve. All of reasons are damaged seal loop or seal gasket, thus change new sealed components as soon as quickly. fuel dispenser

lyphis, apparently, does not. Like honeybees and ancient mariners, they can navigate by the sun, so they know the general direction in which to travel. But, also like ancient mariners (who knew their latit fuel dispenser ude, but not their longitude), such solar reckoning cannot tell them when to stop. Dr Wittlinger, therefore, decided to investigate a century-old hypothesis that desert ants have internal pedometers—in other words, they count their steps out, and they count them back. When one total matches the other, they are home. To test this idea he trained his ants to walk from their nests to a feeding station through a ten-metre-long channel. When they had picked up the food, he caught them and made them return through a different channel, which also led to the nest. When they made this return journey, they began their characteristic nest-searching behaviour, quartering the ground in detail looking for the entrance, after travelling about ten metres. Once the ants had mastered this trick, the experiment proper began. Some ants, when they arrived at the feeding station, had the ends of their legs amputated, to shorten their stride length. Others were fitted with stilts in the form of pig-bristles glued to their feet. Both lots were then returned to the feeding station, to make the journey home. As predicted, the ants on stilts, whose stride-length meant their internal pedometers had not clicked enough times, walked blithely past their nests, and were left stranded almost five metres on the far side before they started looking for the hole. Meanwhile, the poor stumped ants travelled only about six metres before they started their search. The story, however, fuel dispenser has a happy ending. Having proved his point, Dr Wittlinger returned both stumped and stilted ants to the nest and gave them a few days to recover. Then he let them out for another run. Now that they could re-count their outbound journeys, they were able to calculate the journey home correctly. Ants may not be very bright, but it seems they fuel dispenser
