    ine bad effects of accuracy. 2. Pipeline noise Noise and tremble are not generated by pipe itself but hydraulic shock, pipe resonance and pressure pulse. Here explain, combining operation and maintenance of fuel dispense, these reason for noise and tremble 2.1 Hydraulic collision Hydraulic collision refers to the phenomenon in which oil pressure in pipeline is increased quickly as pipe switch op fuel dispenser en or close or liquid changing flow direction. Hydraulic collision could lead to pipeline noise, which are result from piston changing direction of measurement transducer and witching on or off pipe valve.

They also explain that slowly switch on and off nozzle generating less collision pressure than that of rapidly under a certain parameter of pipeline system of fuel dispenser. Similarly, it is applicable to stock noise. Therefore, user shall slowly turn on and off nozzle in operation so as to reduce hydraulic stock and noise, and prolong fuel life service of fuel dispenser. Most of manufacturers of fuel dispensers have mounted anti fuel dispenser hydraulic stock device in hydraulic system in order to abate the effects to fuel dispensers.

    with exactly the same tools as they used in 2004 administrative controls to curb excessive investment in specific industries, overlaid with a sporadic tightening of monetary policy. Spending restrictions have already been tightened in industries such as aluminium, steel and cement. And last week Wen Jiabao, the prime minister, warned local governments and banks to stop financing so many constructi fuel dispenser on projects. On June 16th the central bank, having raised its lending rates by 0.27 percentage points in April, demanded that commercial banks increase the ratio of reserves they deposit in its vaults by half a percentage point. Jun Ma, an economist at Deutsche Bank, expects policy to be tightened further, possibly through another rise in interest rates, in coming months. Would that be enough? The measured response of the authorities two years ago was hailed as a success at the time. With hindsight, it appears too lax, given that the same problems have resurfaced so rapidly. Stephen Roach, chief global economist at Morgan Stanley, argues that China s economy is now simply too large—having grown so rapidly in the past couple of years—for microeconomic measures such as investment restrictions in specific industries to work. Instead, the authorities should use the macroeconomic levers at fuel dispenser their disposal to slow growth, possibly by tightening fiscal policy or by allowing the yuan to strengthen. The Communist Party s fear of undermining its hard-won legitimacy by choking off growth is understandable. Yet unless it avoids what Mr Roach calls “the pitfalls of incrementalism? the likelier it is that China s economy will face a hard landing in the future. China s excessive growth is not only of domestic concern. With much of the world increasingly worried about inflation, questions arise about what an overheating Chinese economy could do to global prices. I fuel dispenser t seems strange to worry about China exporting inflation—as Mervyn King, governor of the Bank of England, did recently—when the country s
