ank and fuel dispenser. It is incomprehensive to think that the higher vacuum pressure in inlet the better performance. Here is vacuum pressure of pump inlet formula: PZ = Pa－P1= P gh＋P [(υ1)2/2 ] = P ghf (2-9) PZ ── vacuum pressure of pump inlet Pa── absolute atmospheric pressure P1── absolute pressure of pump inlet g── acceleration of gravity h── height from pump inlet to oil level in tank υ1── velocity of pump inlet hf── energy loss in pipe from tank to pump inlet from formula 2-9, there are three exterior conditions depend vacuum pressure of pump: pressure needed to lift oil, σgh; the pressure that used to increase flow velocity, P [(υ1)2/2 ]; the pressure loss in pipeline, P ghf . Once oil contains fuel dispenser air, along with pressure decrease, more air is separated. So dose that along with inlet vacuum pressure increases. Under there conditions, cavitation would occur in pipeline, causing pump’s normal operation. In order to prevent above disadvantage effects, pay much attentions to installation of pipeline: ①tank should not be burred too deeply, the vertical distance from bottom valve to fuel dispenser no more than 4m, for example, regulated by some manufacturers with the purpose to prevent higher vacuum pressure of pump inlet; �?the diameter of pipe should not too small. As flow velocity correlate to section of pipeline, vacuum pressure at inlet of pump will be increased when high velocity in smaller diameter pipe; adopt as few as elbow in pipeline, preventing the connection with different diameter pi fuel dispenser pe, adopt pipe with smooth pipe wall. Rational installation of pipeline between tank and fuel dispenser benefit avoiding cavition and reduce vacuum pressure of pump inlet, which is also conducive to deduct business cost and power consumption. The unreasonable pipeline installation not only results in suction difficulty but also easily generate no suction in hot whether, increasing power loss. The wrong installation also leads to larg fuel dispenser

Corbis MANKIND S progress in developing new gizmos is often referred to as the “march of technology�? That conjures up images of constant and relentless forward movement orchestrated with military precision. In reality, technological progress is rather less orderly. Some technologies do indeed improve at such a predictable pace that they obey simple formulae such as Moore s law, which acts as a battleplan for the semiconductor industry. Other technologies proceed by painful lurches—think of third-generation mobile phones, or new versions of Microsoft Windows. There are even the occasional backward steps you can skip over the trailers when watching a film on video, but for so fuel dispenser me reason you are not allowed to do so when watching a DVD. And there are some cases, particularly in the developing world, when technological progress takes the form of a leapfrog. Such leapfrogging involves adopting a new technology directly, and skipping over the earlier, inferior versions of it that came before. By far the best-known example is that of mobile phones in the developing world. Fixed-line networks are poor or non-existent in many developing countries, so people have leapfrogged straight to mobile phones instead. The number of mobile phones now far outstrips the number of fixed-line telephones in China, India and sub-Saharan Africa. By their very nature, mobile networks are far easier, faster and cheaper to deploy than fixed-line networks. There are other examples. Incand fuel dispenser escent light bulbs, introduced in the late 1870s, are slowly being displaced in the developed world by more energy-efficient light-emitting diodes (LEDs), in applications from traffic lights to domestic lighting. LEDs could, however, have an even greater impact in parts of the developing world that lack mains power and electric lighting altogether. LEDs greater energy efficiency makes it possible to run them from batteries charged by solar panels dur fuel dispenser
