oil, so as to reduce the volume of drained oil. Turn adjusting bolt clockwise to reduce discharge, anticlockwise to increase discharge. Therefore, changing the position of bolt enable discharge approach academic volume and reach the requirements on measurement transducer of national appraisal regulations. As two regulative bolts access to adjusting piston, the adjusting discharge fuel dispenser i fuel dispenser n a circulation per bolt can be calculated in the following formula: △V = 1/2πd12 nt (2--4 ) △V ── adjusting value in per circulation; D1 ── diameter of regulative piston; n ── turning number of adjusting bolt; t ── screw- pitch of adjusting bolt. There is another metal piston measurement transducer in current market. See the Diagram 2-19. Regulative piston is singularly installed in piston rather than connect with rod in this model. Its adjusting value in terms of per adjusting bolt is: △V = 1/4πd2 nt (2--5 ) Common failure and Troubleshooting Metal piston measurement transducer has the two common failures --- accuracy decline and mechanical trouble. Measure accuracy beyond scope The allowed measurement accuracy of fuel dispenser is ±0.3 %, repeated tolerance no more than 0.15 % according to the stipulation of JJG443-98 Fuel dispenser. The maximum allowed tolerance of min. measured valve don’t exceed ±0.5 %，its repeated tolerance no more than 0.25 %. The ratio of maximum flow (Q max.) to minimum flow (Q min.) is 10 to 1. as fuel dispenser leave factory. The ratio should not be less than 5: 1 in inspecting at operation locale. All of exceeded tolerance is regarded as beyond measurement accuracy. There are many elements and reasons resulting in measurement accuracy beyond scope, including unstable hydraulic system (extensive pressure fluctuation), electric system failure, thick colloid in frictional interface, measurement transducer abrasion, etc. The last two reasons will fuel dispenser mainly be introduced in this article.

o penetrate a little way into rock. The argument is complex. The administration still thinks that bunker-busters would deter proliferators, by making it harder to hide nuclear, chemical or biological weapons. Congress worries that any weapon that can penetrate rock will throw up lots of radioactive fallout. Meanwhile, even just researching such weapons has made it harder for t fuel dispenser h fuel dispenser e administration to argue that North Korea and Iran should halt any weapons-tinkering. David Hobson, chairman of the mild-sounding House energy and water appropriations subcommittee, has led the attack on the bunker-buster. (His problem with it, he once said, is that “some idiot might try to use it.� Instead, he helped vote some $25m for a different project the reliable replacement warhead (RRW). The idea is to redesign new parts for America s ageing stockpile that would make the warheads more reliable, longer-lived and safer to maintain. This sounds like prudent housekeeping; in fact, it could have a much more radical effect than the bunker-buster, whose use was limited. During the cold war, the trick was to get the biggest possible bang into smallish warheads that could be clustered on a missile. That meant pushing the designs and materials used to build the bombs to their limits. As such weapons age, the worry is that they may deteriorate faster. Checking them requires tricky and costly maintenance. Now the idea is to try using different, less toxic materials and to put in extra safety and security features to make sure the warheads work and last longer. Ideally, you might not even have to test them. Already two of America s weapons labs are busy on designs. But RRWs open up plenty of possibilities. Some of them are good. For instance, if warheads are more reliable, safer and easier to maintain, America could get rid of even more of those it holds in reserve in case some weapons develop flaws, and cut back its spending on fuel dispenser the infrastructure for maintaining the stockpile. But more difficult question
