    fuel dispenser Main frame installation The installation method of submersible pump fuel dispenser is similar to that of suction pump fuel dispenser. The horizontal distance from main frame to underground tank is no more than 60m, vertical distance no exceeding 4m, delivering pipe with less 0.2% slant, elbow as few as possible. Power supply lead, control line and communicating cable are installed respectively. Main wire pipe adopts 2’?seamless steel pipe, branch 1 1/2 ‘? Pressure testing of pipe should be conducted strictly in accordance with stipulation of GB50156 because the working pressure of submersible pump is 0.25~~0.3Mpa, even 0.63Mpa in instance. Safety valve should be installed in submersible fuel dispenser pump fuel dispenser, connecting pipe with stainless steel corrugated pipe. It should be installed at the angel iron fixed in concrete, connecting with pipe. (Illustrated in Diagram 5-11) 1.1 Electric installation Electric installation includes power supply installation and connection of fuel dispenser with junction box assembly. 1: Oil filter end 2: Gasket 3: Check valve 4: Pipe 5: Safety valve 6: U-shape bracket 7: Angle iron 8: Upper flange 9: Corrugated pipe 10: Low flange Diagram 5-11: Inlet connection sketc fuel dispenser h map of fuel dispenser Power supply installation (reference to Diagram 5-12): adopting oil-resistance and erosive resistance three threads copper cable, section no less than 1mm2, outside diameter about 8mmm. User’s lines and signal cable are connected into explosion-proof junction box. 1.2 Junction box installation There are many items installed in Junction box, including terminal, power breaker (switchers of power and fuel dispensers), touch-switch, hot protection relay, general relay controlled by low voltage, signal terminal and fuel dispenser control board of submersible pump. Other installations should be conducted strictly in accordance with electric control drawing. 1.3 Submersible pump installation Submersible pump is delivering equipment with positive pressure, which

The Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) protocols are  transport protocols corresponding to O fuel dispenser SI layer 4. Both protocols make use of the Internet Protocol (IP) an OSI layer  3 protocol (the network layer). As well as these three protocols there are two more basic protocols in the TCPIP  suite that extend the IP protocol: ICMP and IGMP. The functionality of these protocols must be implemented in the  layer housing the IP protocol.  ICMP and IGMP stands for Internet Control Message Protocol and Internet Group Management Protocol.  A.2 TCPIP Transmission Control Protocol  Connection-oriented communication can use fuel dispenser reliable communication where the layer 4 protocol sends  acknowledgements of data receipts and requests retransmissions if data is not received or is corrupted.

    ht? Although her security hard-talk provoked much liberal hand-wringing in Paris, it drew applause at a meeting in northern France. A poll in Le Figaro suggested that 66% of the French agreed with her. Many left-leaning voters are fed up with the party s soft approach, which often excuses criminality. Moreover, fears about security are feeding the far right. In one poll, a staggering 31% of voters say they want the National Front s Jean-Marie Le Pen to stand for the presidency. A second element in Ms Royal s strategy is to use her poll ratings to conquer the party, where she lacks a base. A new opinion poll by TNS-Sofres shows her to be France s most popular politician, fully ten points ahead of Mr S fuel dispenser arkozy, and the only candidate on the left who would beat him in a run-off. Thanks to an internet membership drive, the Socialist Party has expanded to over 200,000 members, a jump of almost 60% since March. An internal poll shows that many newcomers have neither belonged to a party before nor set foot in a Socialist meeting. Yet all those registered by June 1st will help to choose the presidential candidate in November. They could be just the sort who are drawn to the novelty and sense of renewal that Ms Royal seems to embody. fuel dispenser All the same, leading Socialists expect Ms Royal to trip up. Their rancour is breathtaking. Many consider her a media creation just waiting to implode. “The media is not interested in competence,?laments one, “only in a beauty contest.?One fear is that the party might pick her as a candidate—only for her to tumble afterwards, wrecking the left s chances next spring. According to one insider, her rival candidates are working towards an informal pact to back each other in the run-off for the party s nomination, in a bid to thwart fuel dispenser Ms Royal. Some are even muttering about bringing back Lionel Jospin, a retired former prime minister. If the presidential election were held tomorrow, “Ségo?and “Sarko?would cruise to the second round.
