Responsive To Accumulation Of Pumped Liquid In Receiver Patents (Class 417/36)
  • Patent number: 11168547
    Abstract: A device is provided for pumping fluid from a wellbore up to surface. The device includes a stator unit, a rotor unit run within the stator unit on a rod string, the rotor unit and the stator unit engaging with one another to form an annular space therebetween for passage of fluid. An upstream check valve on the rod string uphole of the rotor unit is moveable from an open position in which fluid is passable through the annular space, and a closed position in which fluid passage through the annular space is prevented. A hollow rod section extends through the rod string in fluid communication with the annular space both downstream and upstream of the upstream check valve, for entry of fluid into a downhole end of the hollow rod section, passage of fluid upstream therefrom and exit of fluids from an uphole end of the hollow rod section, back into the annular space. A method is further provided for pumping fluid from a wellbore after shutdown.

  • Patent number: 10760937
    Abstract: A system includes a container having an inner chamber for storing fluid, at least one measuring probe arranged within the chamber and one ground probe arranged within or near a bottom of the chamber. There is at least one impedance electrically connected with a processor which is electrically connected with the at least one measuring probe. A signal generator has a first voltage terminal electrically connected with the at least one impedance and a second voltage terminal electrically connected with the ground probe. When a signal is sent from the signal generator to the measuring probe, an electrochemical reaction occurs at the measuring probe and ground probe and stores a charge if the measuring probe and/or ground probe are immersed in fluid. The processor measures the voltage, current and power of the signal to calculate the resistance and capacitance of the fluid within the container to determine the level of fluid in the container.

    Abstract: A system is taught for automatically siphoning water out of a sump pit or reservoir that only relies on domestic water as the sole source of motive power to automatically evacuate water from a sump pit. This pump system uses neither electricity nor floats as it mechanically amplifies a small pneumatic pressure signal—a change in air pressure—to turn on and off a higher-pressure hydraulic source such as a domestic water supply having a pressure of approximately 60 psig. The present sump pump system further teaches an eductor Venturi assembly having an annular groove in the fluid outflow conduit that creates pumping suction using the principle of differential pressure created when a fluid transitions from laminar to turbulent flow. This sump pump system operates with or without backpressure unlike some systems of this type.

  • Patent number: 8651824
    Abstract: A condensate pump for an HVAC system includes a reservoir for collecting condensate water, a pump motor connected to an impeller pump for pumping the condensate water out of the reservoir, and a floatless pump control module. The floatless pump's microcontroller detects the water level in the reservoir and, based on the water level in the reservoir, controls the operation of the pump motor, and if necessary, sounds an alarm and shuts down the HVAC system. The floatless pump microcontroller may employ an ultrasonic transducer or capacitance sensors to detect the level of condensate water in the reservoir. The microcontroller implements a variable water lift feature to pump the water using the lowest possible speed for the pump. The microcontroller implements a self-cleaning feature to pump stagnant water out of the reservoir and to pulse water in the drain line and the agitation of the water in the reservoir.

  • Patent number: 8641384
    Abstract: The present invention provides a sump pump control system. The system includes a mounting fixture fabricated from a corrosion resistant material, and an electrical control comprising solid state electrical components supported by the mounting fixture. The sump pump control system also includes a diving bell cover. The diving bell cover has an open bottom, and is dimensioned to cover the electrical components. The diving bell cover is releasably secured to a support surface of the mounting fixture. The electrical control controls the operation of a sump pump. Should water rise to a level of the electrical components due to failure of the sump pump or due to quickly rising water, the diving bell cover will prevent water from contacting the electrical components. A method of removing water from a subterranean vault is also provided herein.

  • Patent number: 8550110
    Abstract: Systems for removing water from an area where water is not desired are discussed and provided. The system can include a dam, a water collection system, and a water removal system. The dam can create a waterproof seal so that the dam is configured to define a reservoir, or retention area, capable of holding water. The water collection system can remove substantially all of the water that collects in the retention area and deposit the water in a reservoir when the water collection system is triggered by a first sensor. The water removal system can move the water collected in the reservoir to an area of safe disposal through a hose or drain when triggered by a second sensor. Other aspects, features, and embodiments of the present invention are claimed and described.

  • Patent number: 8545189
    Abstract: A method and an arrangement for controlling a pump station includes measurement of the surface level of a liquid (465) by means of a sensor (452) and controlling the electric drive (401, 420, 430) of the pump (440) to a predetermined speed of rotation when a specific surface level value has been reached. This predetermined rotation speed value is preferably the rotation speed at which the ratio of the flow rate to the consumed power, i.e. the efficiency, is optimal. The measurement of the surface level and the related data processing for control of the pump are performed in a frequency converter (420) in conjunction with the control.

  • Publication number: 20130115106
    Abstract: A sump water evacuation system that operates automatically without reliance on electricity or floats and without any need for oversight or manual intervention, using domestic water supply as the sole motive force to evacuate sump water either into a washbasin or to the exterior of the building; the system is easily installed for use with Radon remediated sump pits. A pneumatic stagnation pressure automatically signals a rising water level in a sump pit and this signal is communicated to a housing wherein the low-pressure signal is mechanically amplified to activate a tilt valve mechanism, thereby converting the pneumatic signal to a hydraulic force which in turn opens a check valve, allowing a high-pressure domestic water supply to flow through to a commercially available Venturi siphon device, causing the sump water to be suctioned out and expelled into either a washbasin or to the exterior of a building.
