摘要： A landfill pump cycle counter includes a housing defining an internal passage, a poppet disposed within the internal passage, a magnet disposed within an internal cavity of the poppet, a counter, a seat formed on an inner surface of the housing, and a mating surface formed on the poppet. The landfill pump cycle counter is configured to receive liquid output from a landfill pump. The housing extends along an axis and also defines an inlet and an outlet. The internal passage fluidly connects the inlet to the outlet. The poppet is configured to be moved axially between an open state and a closed state. The counter includes a magnetic sensor configured to detect a poppet cycle. The poppet cycle includes the poppet moving from one of the open state and the closed state to the other of the open state and the closed state.

摘要： The present disclosure relates to a pump system having a pneumatically actuated fluid pump, which makes use of standard cycle counter to assist in determining when an air supply control valve is stuck in an open state after a fluid discharge cycle has completed. The system includes an electronic controller which receives signals from the cycle counter. The signals indicate a position of a sensing element inside the cycle counter. The electronic controller uses the signals to determine if the sensing element is still experiencing a pressurized airflow after a fluid discharge cycle has completed and the air supply control valve has been commanded to close.

摘要： Various embodiments concern a pneumatic landfill pump cycle counter comprising a spring located within a housing passage and a shuttle comprising a shuttle magnet, the shuttle located within the passage. The shuttle can be configured to move axially by the spring within the passage in an upstream direction to a home position, move axially by one or both of air pressure differential and airflow within the passage in a downstream direction away from the home position to a hold position. The cycle counter can further comprise a counter comprising an element responsive to a magnetic field of the shuttle magnet, the counter configured to increment a numeric count for each complete cycle of the shuttle moving from the home position to the hold position and then back to the home position.

摘要： The present disclosure relates to a sampling pump configured for use in a wellbore for pumping liquid collecting in the wellbore. The sampling pump has a pump component including a motor and an outer housing configured to be inserted into the well bore. The outer housing has an inlet and an outlet. A fluid sensor detects when the inlet of the outer housing is positioned in the liquid in the wellbore. A flexible electrical cable assembly supplies power to the motor and the fluid sensor, and also communicates with the motor and the fluid sensor. A user control panel communicates with the flexible electrical cable and enables a user to control on and off operation of the DC motor from the control panel. The user control panel also has a component which is responsive to signals from the fluid sensor to indicate when the inlet is at least partially submerged in the liquid within the wellbore, as the pump is lowered into the wellbore.

摘要： A system for sampling groundwater from a well that includes a pump configured to be at least partially submerged in the groundwater within the well and pump the groundwater out of the well, a sensor configured to output a signal indicative of the depth of the groundwater in the well, and a controller in communication with the sensor. The controller is configured to receive the signal indicative of the depth of the groundwater from the sensor and compensate for groundwater ingress into the well by adjusting a rate of flow of groundwater pumped by the pump based on the signal to stabilize the depth of groundwater in the well while the pump is pumping groundwater from the well.

摘要： The present disclosure relates to a fluid level sensing system for sensing a fluid level in a well. The system has an upper housing in communication with a lower housing, with the lower housing having a first bore in communication with a fluid in the well, and a second bore isolated from the first bore and in communication with at least one of a vacuum gauge or an external vacuum source. The upper and lower housings house a first flexible bag and a second flexible bag, with the first bag housed within the second bag. A portion of the first bag communicates with the first bore and is responsive to a change in pressure within the first bore caused by a changing fluid level in the well. A portion of the second bag communicates with the second bore and exerts a reference pressure on the first bag. A sensing subsystem senses expanding and contracting movement of the bags and generates a signal indicative of a change in a level of the fluid in the well.

摘要： A pneumatically driven fluid pump apparatus is disclosed which includes a pump casing having an inner wall, a pump cap secured at a first end of the pump casing, and a liquid discharge tube in communication with the pump cap and extending at least partially within an interior area of the pump casing toward a second end of the pump casing, and where fluid is admitted into the pump casing at the second end. The pressurized airflow causes a swirling flow of the liquid within the interior area of the pump casing that helps to clean the interior area of the pump casing by liquid scrubbing action to dislodge debris adhered within the interior area of the pump casing and remove the debris up through the liquid discharge tube and out from the fluid pump apparatus during a liquid eject cycle

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.
