摘要： A submersible turbine pump includes a power head enclosed in a casing. A vacuum source associated with the submersible turbine pump draws a vacuum in the interior space of the casing. A pressure sensor may be used to monitor the vacuum in the interior space to detect a leak in the power head or the casing. If a leak is detected, an alarm may be generated and the submersible turbine pump may be deactivated.

摘要： A pump housing that contains a pump that draws fuel from an underground storage tank containing fuel to deliver to fuel dispensers in a service station environment. The pump is coupled to a double-walled fuel pipe that carries the fuel from the pump to the fuel dispensers. The double-walled fuel piping contains an inner annular space that carries the fuel and an outer annular space that captures any leaked fuel from the inner annular space. The outer annular space is maintained through the fuel piping from the pump to the fuel dispensers so that the outer annular space can be pressurized by a pump to determine if a leak exists in the outer annular space or so that fuel leaked from the inner annular space can be captured by a leak containment chamber in the pump housing.

摘要： A pump housing contains a pump that draws fuel from an underground storage tank to deliver fuel to fuel dispensers in a service station environment. The pump is coupled to a double-walled riser pipe that carries the fuel from the underground storage tank to the pump. The double-walled fuel piping contains an inner space that carries the fuel and an outer annular space that captures any leaked fuel from the inner space. The outer annular space is coupled to a vacuum created by the pump to determine if a leak exists in the outer annular space. An alternate submersible turbine pump has a double-walled housing with a pressure sensor disposed in the interstitial space of the double-walled housing. A vacuum may be created therein to determine if leaks are present in the housing of the submersible turbine pump.

摘要： A vacuum generator that is coupled to a double-walled fuel supply piping internal to a fuel dispenser that carries the fuel from the underground storage tank to the hose and nozzle of the fuel dispenser. The double-walled fuel supply piping contains an inner piping that carries the fuel. An interstitial space is formed by the space between the inner piping and an outer piping that surrounds the inner piping to capture any leaked fuel from the inner piping. The interstitial space is coupled to a vacuum created by the vacuum generator to determine if a leak exists in the interstitial space. The vacuum generator may be a standalone unit or may be a submersible turbine pump that also pumps fuel from the underground storage tank to the fuel dispenser.

摘要： A method and apparatus for monitoring and determining fuel vapor recovery performance is disclosed. The dispensing of liquid fuel into a tank by a conventional gas pump nozzle naturally displaces a mixture of air and fuel ullage vapor in the tank. These displaced vapors may be recovered at the dispensing point nozzle by a vapor recovery system. A properly functioning vapor recovery system recovers approximately one unit volume of vapor for every unit volume of dispensed liquid fuel. The ratio of recovered vapor to dispensed fuel is termed the A/L ratio, which should ideally be approximately equal to one (1). The A/L ratio, and thus the proper functioning of the vapor recovery system, may be determined by measuring liquid fuel flow and return vapor flow (using a vapor flow sensor) on a nozzle-by-nozzle basis. The disclosed methods and apparatus provide for the determination of A/L ratios for individual nozzles using a reduced number of vapor flow sensors. The disclosed methods and apparatus also provide for the determination of fuel dispensing system vapor containment integrity, and the differentiation of true vapor recovery failures as opposed to false failures resulting from the refueling of vehicles provided with onboard vapor recovery systems.
