bolt is first step as measurement accuracy beyond scope. If it doesn’t work, consider other solutions. Some oil is easily full of colloid due to not in accordance with national standard or exposing to air in long storage. Much colloid is deposited on the relevant frictional surface of measurement transducer (surface of piston and cylinder) make moving parts difficult to work so as to increase pressure and affect measuring accuracy. The inlet pressure of measurement transducer usually is little under small flow rate. However, piston resistance is increased due to extensive colloid, even easily appear the phenomenon of refueling without measurement related. In this case, fuel dispenser delivery more oil fuel dispenser than flow measured. Oil full of colloid is also affected the normal operation of vehicle motor. The cardinal solution to this problem is to control the quality and storage time of oil. Carefully clean the colloid on relative frictional surface of measurement transducer as occur the problem, and especially pay much attention to the friction surface so as not to damage mechanical parts. 1-Outlet elbow 2-End cover 3-Piston 4-Frame 5-Connecting sheet 6-Lower connecting rod 7-Upper connecting rod 8-Cylinder bu fuel dispenser shing 9-Adjusting bolt 10-Cap nut 11-Regualting piston 12-Driving elbow 13-Brass bushing 14-O-ring 15-Output shaft 16-Nylon wheel Diagram 2-19: Structural drawing of another kind of metal piston measurement transducer Accuracy decline and leakage caused by mechanical failure. The extensive mechanical abrasion of relevant friction surface of measurement tra fuel dispenser nsducer is main reason of causing accuracy beyond limitation. These parts abrasion result in accuracy decline, such as connecting board, bushing, small brass bushing used as adjusting piston, regulative piston, nylon wheel, etc. The O-rings between connecting rod and piston and on driving elbow tend to expansion to affect accuracy. Generally, disassemble and inspect all components, problem will be solved by changing extensive abrasion or damaged parts.

bomb-building. There will then be pressure on the Nuclear Suppliers Group (NSG) to carve an India-shaped hole in its global nuclear export restrictions, and on the board of the International Atomic Energy Agency (IAEA) to agree to “India-specific�safeguards on any nuclear materials or technology sold. The Bush administration defends its India deal as good for combating global warming, good for friendship with the world s biggest democracy and good for jobs in America. All that is debatable (see article). But its claim that the nuclear deal will be a net gain in the fight against proliferation is pure nonsense. The controversial deal is already undermining confidence in the world s anti-nuclear fuel dispenser rules. The NPT, which has helped prevent a number of other capable states from going nuclear, and encouraged some which tried (Argentina and Brazil) and others which had succeeded (South Africa) to turn back, rests on a promise that only those that renounce nuclear weapons qualify for civilian nuclear assistance. India deliberately stayed outside the treaty to build its bombs; America is now offering it nuclear help anyway. That won t encourage others to keep their non-nuclear promises. Nor has Ind fuel dispenser ia taken on any meaningful new non-proliferation obligations to lighten the blow to the treaty. The recognised nuclear powers—America, Russia, Britain, France and China—are committed under the NPT to curb their arsenals (four are shrinking, only China s bomb-pile is still growing) on the way to eventual disarmament; the deal with America lets India build as fuel dispenser many bombs as it chooses. The five have at least all signed the treaty banning further nuclear tests and have stopped producing more highly enriched uranium and plutonium for weapons; India flatly refuses to do either. The wrong sort of helping hand By lifting restrictions on India s ability to buy nuclear technology and fuel from abroad, America will be helping it out of a uranium squeeze its usable stocks of the enriched stuff (low
