    摘要： A storage tank leak detection and prevention system that detects a breach or leak in the interstitial space of a double-walled fuel storage tank in a service station environment. The interstitial space is placed under a vacuum using a submersible turbine pump that is also used to pump fuel to the fuel dispensers in the service station and therefore a separate vacuum generating source is not required. A sensing unit and/or tank monitor monitors the vacuum level in the interstitial space over time. If a significant vacuum level change occurs in the interstitial space after the interstitial space is placed under a vacuum level, a catastrophic leak detection alarm is generated. If a minor vacuum level change occurs in the interstitial space after the interstitial space is placed under a vacuum, a precision leak detection alarm is generated. Functional tests also ensure that the leak detection system is functioning properly.

    摘要翻译： 一种存储罐泄漏检测和预防系统，其检测在服务站环境中双壁燃料储罐的间隙空间中的泄漏或泄漏。 间隙空间使用潜水涡轮泵在真空下放置，该潜水泵也用于将燃料泵送到维修站中的燃料分配器，因此不需要单独的真空发生源。 感测单元和/或罐监视器随时间监视间隙空间中的真空度。 如果间隙空间置于真空度之后，间隙空间发生显着的真空度变化，就会产生灾难性的泄漏检测报警。 如果在间隙空间置于真空下之后，间隙空间发生微小的真空度变化，就会产生精密的泄漏检测报警。 功能测试还确保泄漏检测系统正常工作。

    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 carbon canister for use with a fuel storage system having a fuel storage tank and a vent line connected thereto. The carbon canister includes an inner container having a first end and a second end, an outer container having a first end and a second end, the outer container being disposed about an outer surface of the inner container such that the outer container and the inner container are concentric. A first end plate is disposed at the first end of the inner container and the first end of the outer container and a second end plate is disposed at the second end of the inner container and the second end of the outer container, such that a first volume is defined by the inner container, the outer container, the first end plate and the second end plate, and hydrocarbon adsorbing activated carbon disposed in the first volume. The vent line of the fuel storage tank is external to the carbon canister and the first volume of the carbon canister is in fluid communication with the fuel storage tank.

    摘要： A carbon canister to adsorb hydrocarbons from a hydrocarbon air mixture in a UST system to prevent fugitive emissions due to overpressurization. The carbon canister has an inlet port at one end coupled to the UST system. An outlet port on the opposite end of the canister is connected to a flow-limiting orifice with a known calibrated flow rate that vents in a controlled fashion to the atmosphere. When UST pressure rises slightly above ambient pressure, fuel vapors and air from the UST system enters, via the inlet port, into the canister, where hydrocarbons are adsorbed onto the surface of the activated carbon. The cleansed air vents through the controlled flow outlet port to atmosphere, thereby preventing excessive positive pressure from occurring in the UST system. The activated carbon is purged of hydrocarbons by means of reverse air flow caused by negative UST pressures that occur during periods of ORVR vehicle refueling.
