    enerates 65”~85”W.C. vacuum pressure as operation, reclaiming vapor through reclaim pipe and nozzle, redundant vapor discharging out of exhaust pipe after vacuum pressure cap automatically open. Diagram 4-10: Built-in pump fuel dispenser with vapor recovery function Built-in pump fuel dispenser with vapor recovery function Showed in Diagram 4-10, this kind of fuel dispenser is mounted a vane pump that connected with the parallel pipes of oil delivery and vapor reclaim, in final connect into tank. At the refueling progress, motor drive vane pump operating and reclaim tank vap fuel dispenser or through nozzle and coaxial hose. System maintenance Nozzle and delivery pipe used in fuel dispenser with vapor recovery function are coaxial and double layers, simultaneously refueling and reclaiming. Paying much attention to nozzle body and delivery hose, in case of waste, bad operation and crush by vehicle. If system alarm, carefully judge the type of alarm of monitor system whether vacuum degree or exhaust pipe pressure. Adjusting and testing vacuum pump and reclaim nozzle in for situation. Inspect air cap in the latter situation. If breakaway is pull down by accident, reinstall spare p fuel dispenser in on upper of valve body. Don’t replace the coaxial and double layers valve with general one. Troubleshooting of vapor recovery equipment Oil spurt from nozzle’s reclaim spout before refueling. Solution methods: Prohibiting force refueling; Wait several seconds to take out nozzle from vehicle tank. Nozzle jump to stop in refueling process Solution methods: Maybe caused by second time operation, it is suggested not to force filing; Wait several seconds to take out nozzle from vehicle tank. Clean waste or deposited oil in air pipe of reclaiming nozzle or inspect O-ring seal. Chapter V Installation & debugging of fuel dispenser The design of fuel dispenser correlates to the correct operation. Fuel dispenser is designed to install outdoor with underground tank, not allowed to be in indoor so as to endure environmental fuel dispenser

The billions and trillions involved in derivatives trading are liable to worry outsiders, though the banks claim to be in control of the situation. True, the net position of a fuel dispenser bank in the derivatives market may not be a very big number by the standards of its balance-sheet totals at any one time.
