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 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 sketch 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 fuel dispenser 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 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 fuel dispenser fuel dispenser
