摘要:
A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system.

A foot valve assembly for a submergible pump including a substantially open-ended submergible pump housing having an interior volume is disclosed. The foot valve assembly also includes an actuator configured to be operated by pressurized fluid. The foot valve assembly also includes a sealing mechanism positioned at the open end of the submergible pump housing and configured to alter fluid flow into the pump housing. The sealing mechanism is attached to the actuator. The actuator is configured to move the sealing mechanism between a first position and a second position, the first position being a closed position and the second position being an open position.

A modular platen assembly comprises an annular hub, a wiper ring assembly and a coupling ring. The annular hub is for connecting to a ram of an inductor pump. The wiper ring assembly includes an annular wiper for sealing with a container. The coupling ring is independently joined to the hub and the wiper ring assembly at first and second connections, respectively.

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.

The present invention provides a submersible turbine pump (STP) comprising a check valve located within a hydraulics cavity, wherein the STP provides the ability to depressurize the hydraulics cavity by relieving a pressure differential between an inlet side and an outlet side of the check valve. In general, the STP is comprised of a casing body comprising a check valve extraction housing and the hydraulics cavity. The check valve is located within the hydraulics cavity and is comprised of a check valve stem, an inlet side, and an outlet side. The check valve extraction housing comprises a lock-down screw adapted to attach to the check valve stem and apply a force to the check valve to open the check valve, thereby relieving the pressure differential between the inlet side and the outlet side.

A tank mounted discharge conduit assembly for use with a submersible pump unit comprises a base member connected to the tank as well as an upright body having a fluid conduit therein. The base member has an upwardly extending portion which is complementally received within a lower portion of the upright body, in order to provide support against lateral deflection of the body as well as to prohibit the flow of fluids through a lower end of the conduit. The body also integrally includes a pair of upright, spaced, elongated, U-shaped guides which are configured to slidably receive an outlet flange of the pump and shift the latter toward a position of fluid communication between the pump and an opening in the body communicating with the fluid conduit therein. The guides advantageously include yieldable wall portions which accommodate lateral movements of the pump unit to facilitate raising and lowering of the pump by a rope-equipped hoist when the latter is unintentionally vertically misaligned with the center of gravity of the pump unit.

A paint bucket may have a funnel shaped bottom to collect paint into a recess while a powered painting system draws paint from the bucket for application to a surface. The recess may receive an intake nozzle from the powered painting system. An insert may create a funnel shaped bottom and recess in a standard flat bottomed bucket.
