    layers of oil resistance and erosive resistance. Single thread and aluminum wire are prohibited. Diagram 5-7: Wiring in TN-S Power supply system The connection between fuel dispenser and distributing room adopts bushing-pipe burry, preventing vehicle crush wires. The wire pipe installed at bottom of fuel fuel dispenser dispenser should have downward elbow in case oil pouring into and erode wire. No jointer is set between the pipeline of junction box and wire outlet, in case of sparkle jeopardy. User’s wire should correspond to earthing line and power lines after importing exploision-proof junction box. Tighten nut and clamp wires ensuring the explosion-proof performance. Change one of three wires if motor does not work. If adopting TN-S power supply system, wiring from switchboard are connected as diagram 5-7 illustration. If adopting TN-C-S OR TN-C system, wiring as Diagram 5-8. Grounding of fuel dispenser is in well condition. It is to adopt brass wire with PVC insulting bushing as communicating line between fuel dispensers. Communicating line is buried in galvanized pipe. Diagram 5-8: Wiring in TN-C-S or TN-C Power supply system Fuel dispenser should set single earthing line, with resistance no more than 4Ωto earth, 10 Ωnozzle to earth. User’s wire should adopt copper line with no less than 6mm2 section in single phase motor. Otherwise, there is something wrong with motor, even resulting in electric trouble. Diagram 5-9: Wiring Diagram of fuel dispenser Communicating Box Article II Submersible pump type dispenser and its installation Compared with fuel dispense mounted suction pump, submersible pump fuel dispenser has many merits such as low noise, stable operation, cost-efficient pipeline, and is installed in large station, which is the development direction of fuel dispenser industry. Submersible pump f fuel dispenser uel dispenser consists of main frame, submersible pump and electric control box, which are communicated through electric and signal cable. See Diagram 5-10.

    on their networks. The idea has deep roots it would seem odd, after all, if telephone companies limited whom you could call, or what you could say to them. In the digital era, net neutrality underpins the innovative culture of the internet. The network blindly delivers data packets regardless of what the fuel dispenser y contain, allowing for new applications—such as the web, or internet telephony—without requiring permission from network operators. But now internet firms such as Google and Vonage, plus consumer and internet-advocacy groups, fear that net neutrality could be under threat from America s big telecoms firms, particularly Verizon and AT&T, which this week announced plans to buy BellSouth (see article). Both are building fibre-optic networks over which they plan new services, notably television, to compete with cable operators—themselves moving into telephony. And both firms would like to subsidise the new networks by charging big websites for premium services, such as fast or guaranteed delivery. In effect, they plan “express toll lanes�alongside the internet s existing highways. That would be bad, say proponents of net neutrality, since some data packets—from those agreeing to pay extra� would be favoured over others. Once one music-download service paid up, its rivals would have to do the same. Internet traffic would migrate to the toll roads, enriching operators but limiting choice and innovation. Only laws forcing operato fuel dispenser rs to respect net neutrality can save the internet, say campaigners. It sounds worrying. Yet some packets are already favoured, even on today s internet. Businesses routinely pay a premium for fast, secure “tunnels�through the network. Firewalls and virus filters discriminate against suspicious traffic. Big companies already pay extra for hosting and “conte fuel dispenser nt delivery�services to make their websites download faster. This has not hampered innovation. And telecoms operators insist that they have no intention of blocking or slowing existing traff
