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 fuel dispenser and tremble 2.1 Hydraulic collision 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 ── diffused 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 pipeline system of fuel dispenser. Similarly, it is applicable to stock no fuel dispenser ise. 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. fuel dispenser

went on a Grand Tour of Europe to further their education. Nowadays even moderately well-off students often take a break between school and university to go round the world. Some teach in Thailand, others trek in Tanzania. Most combine fun with s fuel dispenser ome sort of do-gooding. The advent of higher tuition fees seemed likely to put paid to this fine British tradition. Students were expected to eschew backpacking in 2005 to avoid the higher annual fees of £3,000 due to come into effect this year. Later generations would scramble to get their degrees and into the job market to repay their debts. But that has not proved the case. In 2005, according to the Universities and College Admissions Service, 31,059 students accepted by universities deferred taking up their places—more than the 28,435 who did so in 2004. Some were able to lock in lower fees by stating their intention in good time, but many were not. On early estimates, deferred places this year may be running at nearly the 2004 level. The true number of gap-year students is far higher, however, for more are choosing not to seek a university place until after their break. Tom Griffiths, founder of the website www.gapyear.com, says that as many as 50,000-60,000 young people—equal to more than a tenth of those entering university—are currently taking time out each year. He expects the figure to rise to 100,000 over the next three years. But gap years now involve more work and less play. According to NatWest, a bank, students starting university this year will graduate with an average debt of £14,779. Such sobering forecasts create an incentive for them to build up savings ahead fuel dispenser of time and improve their chances of getting a good job when they graduate. The work-experience gap year meets both these requirements, and Mr Griffiths says it is one of the fastest growing gap-year options. Schemes such as The Year In Industry offer business experience and a fair salary. William Jackson, a 19-year-old student, has just completed a 12-mont fuel dispenser
