reclaimed into tank relying on the special device on nozzle and via nozzle and motor. Non-burn system is widely adopted recently, vapor reclaiming in tank. In principle, the proportion of vapor and oil is 1 to 1, namely, each 1L oil decrease correspond to 1L vapor reclaimed to tank. A good capacity vapor recovery device should applicable to various kinds of vehicle inlet. In domestic market vacuum-aid vapor recovery is widely employed recently. Diagram 4-2: Pipeline Installation of Phase I Vapor Recovery Diagram 4-3: Phase II Vapor Recovery System Safety distance of vapor recovery system The safety distance between filling station that installed vapor recovery system and nearby construction and road could reduce by 30% tha fuel dispenser t of non vapor recover system. Equipment deployment of vapor recovery system 4.1 The difference among various brand vapor recovery equipments are dealt method to vapor volume and refuel volume, dividing as the following three types: Adopting adjusting valve to regulate vapor influx: this method utilizes the pressure generated by oil fuel dispenser flow to control air inlet, speed flow large air inlet, vice versa. Adopt electric pulse signal: to control frequency-varying motor through pulse signal, rotation of motor depend upon that of electric pulse. The type also reach 1 to 1 ratio of vapor recovery, mounting computer board. Adopt after-deal system: large amount of vapor fuel dispenser and air is suck to tank using vacuum pump, in tank abundant vapor and air being burn or reclaimed. Main components in vapor recovery system. The system includes vacuum pump, separated jointer, breakaway valve, coaxial hose and nozzle. Vacuum pump: there are two kinds of pumps----- centre-type reclaiming vacuum pump and distributed reclaim vacuum pump. Center-type reclaiming vacuum pump: adopt one or two vacuum pumps reclaiming vapor into tank, including power type and non-power type.
