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 fuel dispenser , 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 e fuel dispenser xplosion-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 control board of submersible pump. Other installations should be conducted strictly in accordance with electric control drawing. 1.3 Submersible pump fuel dispenser installation Submersible pump is delivering equipment with positive pressure, which

carriers. Meanwhile, a domestic jet-fuel monopoly means fuel accounts for an average of 40% of costs at Chinese airlines, compared with 24% for airlines worldwide. Another issue is rising labour costs due to a lack of qualified fuel dispenser staff. In particular, China will need more than 1,000 pilots a year over the next decade, but with only one state flying school, Guanghan near Chengdu in Sichuan province, it can train 600 at most. Air China admitted this month that its planned introduction of 20-30 new aircraft in 2006 depended on it being able to man them. The suppliers are aware of this problem. Airbus has a training centre in Beijing and is setting up simulators elsewhere—as is Boeing. China is also allowing some private training schools to spring up, while China Southern already has its own training centre in Australia. But the shortage is acute and Chinese airlines are now talking of recruiting, reluctantly, pilots from overseas. Not only do they regard this as a blow to national pride; foreign crews also cost more. Their weak profitability, coupled with ambitious plans to expand capacity, leaves the mainland carriers exposed to even a temporary slowdown in traffic growth. Further consolidation, allowing an attack on their structurally high costs, is one remedy. Another would be to liberalise the market for both fares and fuel. A braver step would be to let in foreign operators to boost competition. Finally, the oft-speculated three-way merger of Hong Kong s Cathay Pacific and Drag fuel dispenser onair with Air China would create a world-class carrier and spread best practice. Whichever route the government chooses, it needs to act rapidly. After all, the industry has been hit by at least one major shock every three years, from terrorist attacks to the SARS virus. After a couple of good years, the next bad one is due some time soon. © 2006 .  About sponsor fuel dispenser ship Time Warner Sweet surrender Feb 23rd 2006 From The Economist print edition
