摘要： The present disclosure relates to a pneumatically driven fluid pump apparatus having an outer pump housing for collecting liquid to be pumped, and a valve assembly in communication with liquid admitted through an inlet end of the outer pump housing and collecting within the outer pump housing. The valve assembly includes a housing assembly and a poppet valve assembly disposed within the housing assembly to act as a one-way check valve when pumping collected liquid out from the outer pump housing. The poppet valve assembly includes a poppet valve component including a relief area that helps to depressurize an interior area of the valve assembly, to facilitate rapid movement of the poppet valve element from an open position toward a closed position, when only a pressurized fluid flow being used to eject the collected liquid is flowing past the poppet valve component.

摘要： A well cap assembly is disclosed which is well suited for use with a wellhead. The well cap assembly has a port component and a cap element. The port component has a bore extending therethrough, an upper neck portion, and an upper threaded portion. The port component further has a lower threaded portion and a barb formed on the upper neck portion. The barb can receive an external flexible tube which is temporarily secured to the port component. The cap element has an internally threaded portion which engages with the upper threaded portion of the upper neck portion and seals the bore of the port component. The cap element also has a tether for securing it to the port component.

摘要： The present disclosure relates to a cycle counter apparatus for use with an air-driven fluid pump. The apparatus may have a main housing having a bore in communication with a pressurized fluid signal being applied to remove a liquid from a location filling with the liquid. A magnet housing may be included which is moveable linearly within the bore of the main housing in response to the pressurized fluid signal entering the bore. A magnet may be secured to the magnet housing. A switch housing may be included which is operably associated with the main housing and which includes first and second longitudinally spaced apart sensing components. The sensing components are used to detect movement of the magnet in response to the pressurized fluid signal.

摘要： A fluid level sensor system is disclosed for sensing a fluid level in a well. The system has a main body and an inlet housing coupled to the main body. The inlet housing has an internal chamber in communication with an ambient environment within the well. A bellows within the main body communicates with the internal chamber of the inlet housing. A movable element is responsive to movement of the bellows. A sensor detects when the movable element moves from a first position, indicating a first fluid level in the well, to a second position indicating a second fluid level within the well. An indicator is operably associated with the movable element and moves into a position to be viewable when the sensing element is moved to the second position, to provide a visual indication that the second fluid level has been reached.

摘要： An air stripper apparatus is disclosed which incorporates a plurality of trays that are removably supported within a cabinet. A plurality of downcomers are also fixedly disposed within the cabinet, rather than on the trays. Removing the downcomer from each tray enables a simpler, lighter and easier to clean tray to be constructed.

摘要： The present disclosure relates to a system for controlling an extraction of landfill gas flow (LFG) from a plurality of wellheads at a landfill. The system has a first wellhead located at the landfill, a first processor having a first rule set, and a first LFG flow control valve controllable by the first processor. A second wellhead is located at the landfill in a vicinity of the first wellhead and has a second processor and a second LFG flow control valve. The second processor has a second rule set and is operable to control the second LFG flow control valve. The first and second processors use their said rule sets to control the first and second LFG flow control valves, respectively, to control an LFG flow through their said first and second wellheads, respectively.
