    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 col fuel dispenser lision Hydraulic collision refers to the phenomenon in which oil pressure in pipeline is increased quickly as pipe switch open 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. Δρ= 12lv11+EoE·dδ (v2=0,t≤T) (2-10) Δρ= 12lv11+EoE·dδ ·Tt (v2=0,t≤T) (2-11) Δρ= 12lv11+EoE·dδ ( partial v2?,t≤T) (2-12) Δρ= 12lv11+EoE·dδ ·Tt (partial v2?,t≤T) (2-13) In above formulae: Δρ── increasing pressure value; υ1── previous velocity of flow υ2── latter velocity of flow T ── time that start from collision to reflect T=2la T ── changing time of velocity of flow fromυtoυ2 E0 ── elastic volume of fluid cubage E ── elastic modulus of pipeline d ── inner diameter of pipe δ── pipe thickness l ── diffused distance of shock wave a ── d fuel dispenser iffused speed of shock wave The above formulae illustrate four kinds of stock pressure on pipe in corresponding operations in which switching on or off nozzle quickly or slowly. They also explain that slowly switch on and off nozzle generating less collision pressure than that of rapidly under a certain parameter of pipelin fuel dispenser e 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 hydraulic stock device in hydraulic system in order to abate the effects to fuel dispensers.

    ck exchanges around the world are listless, share prices in Hong Kong are up by 17%. In mainland China, they have risen by even more. Comfortingly, profitability is rising even faster than share prices. After a nasty bear market, prices are now close to their 2000 peaks. Hav fuel dispenser ing shaken off a sense of gloom, Hong Kong s retail investors now seem to have forgotten things can ever go wrong. They believe the Chinese government is bound to price the deals so share values rise afterwards, in as much as a flop would undermine future privatisations. That may be too optimistic; if the companies were sold too cheaply, the government would be accused of a giveaway. Still, the consensus is that shares in a newly offered company will tick up by 10-15%. Local banks appear to share the confidence, extending margin loans for up to 90% of the initial share price. Allocations may be tiny, but the return on investment can be huge. Large blocks are reserved for Hong Kong tycoons, who in return agree not to flip their shares. Occasionally there are complaints of favouritism. But at least it is clear where the smart money is going. Bankers wanted, Mandarin useful The extraordinary pace of deals should continue for a bit longer but the nature of the offerings w fuel dispenser ill soon change, if only because the largest companies, such as the state-owned banks, will have been sold. Some predict that the value of public offerings could drop by one-third next year. That, of course, would still leave plenty of business, which is why investment banks continue to hire at a frenetic pace. It has nev fuel dispenser er been a better time to be able to read Mandarin and a financial statement. But with the completion of the ICBC offering, probably in November, a different type of state-owned asset will come up for auction. Companies in all sorts of industries will be on offer—metals and mining, coal, rail, steel and ports—as well as smaller banks (though by any ordinary standard, not that small). As the type of companies changes, the offe
