摘要： A sump pump system enables automatic determination and utilization of frequencies for mechanical shakers for sump pumps. These techniques may be implemented to detect a fault (e.g., a stuck impeller) with a sump pump and to identify a desirable frequency at which a mechanical shaker for the sump pump should vibrate to correct the fault.

摘要： A sump pump system may detect and utilize motion or acceleration of water in sump basins when implementing control of sump pumps. To detect the motion or acceleration, the sump pump system may utilize a sensor that is configured to detect motion or acceleration, such as an accelerometer or gyroscope. The sump pump system may identify a water level in a sump basin based on the detected motion or acceleration, which may be compared to a reading or expected signal from the sump pump system's “typical” sensor (e.g., float switch) that is used to detect one or more water levels. In this manner, the sump pump system may detect a malfunctioning level sensor that is used by the pump to detect high-water and low-water marks at which the sump pump activates and deactivates, respectively.

摘要： A sump pump system may implement adaptive learning and machine learning techniques to facilitate improved control of sump pumps. A sump pump system may implement the described techniques to generate, train, and/or implement a machine learning model that is capable of predicting or estimating one or more conditions of the sump pump system (e.g., water level in the basin, motor malfunction, stuck impeller, geyser effect, blocked outlet pipe, faulty level sensor/switch, faulty bearing, failure to engage pump at high-water mark, etc.) based on one or more detected input variables (e.g., acceleration or vibration patterns detected in water, on a pump, or on a pipe; capacitance values of water; audio signatures; electrical signatures, such as power or current draw; pump motor rotation speed; water pressure signatures or values, such as those detected at the bottom of a sump basin; etc.).

摘要： A method of evaluating a wear state of an assembly of a flow machine, in particular, of a bearing arrangement of a pump or turbine. For determining a wear characteristic, a mechanical query signal having a pre-definable signal shape is generated by a signal generator and a response signal generated from the query signal is detected using a sensor in contact with the assembly. The response signal is varied in dependence on a variation of a physical operating value of the assembly in accordance with a characteristic pattern, the wear characteristic is determined from the variation of the response signal and the wear state is evaluated using the wear characteristic.

摘要： A machine such as a centrifugal pump has a rotating impeller which may get out of alignment if there is bearing wear or if the impeller becomes loose on its supporting axle. A misalignment sensing probe and switch may be installed through the housing of the pump with it probe tip in close proximity to the impeller's face. If the rotating impeller migrates out of alignment it will abrade the tip of the sensing probe. Inside the probe body there is secured a stranded insulated electrical conductor with one of its ends in the tip while the other end extends beyond the other end of the body and is connected into an electrical circuit. Abrasion of the tip will force contact between the stranded electrical conductor wire and the body of the probe. This closing of the switch will activate the electrical circuit which has been designed to shut down the power source and/or activate an alarm and thus avoid destruction of the pump.

The device comprise a rotary shaft of a canned motor driven pump having a hole extending in an axial direction from one end of said rotary shaft; an enlarged chamber formed in said hole at a position distant apart from said one end of said rotary shaft by a given distance and having a diameter larger than that of said hole and forming shoulders at boundaries between said hole and said enlarged chamber; and a hermetically sealed pipe provided at its one end with an enlarged sensitive portion and at another end an indicator; said enlarged sensitive portion being enclosed in said enlarged chamber of said rotary shaft. To the one end of the rotary shaft may be secured an end nut with said hole and said enlarged chamber formed therein. The hermetically sealed pipe may be composed of an indicating part and a detecting part telescopically engaged with each other.

摘要： Example systems and methods for manipulating control of sump pumps in order to extend lifespans of the sump pumps are disclosed. An example method includes activating a sump pump a first time; deactivating the sump pump when a first current water level in a sump basin in which the sump pump is disposed reaches a first low-water mark; and determining, by one or more processors, a time since a last activation of the sump pump wherein the last activation occurred when the sump pump activated the first time. When the time satisfies a threshold, the method activates the sump pump at second time, determines, by one or more processors, a second current water level in the sump basin, and in response to determining that the second current water level in the sump basin is below a second low-water mark corresponding to a bottom of an impeller of the sump pump, deactivates the sump pump.

摘要： A corrosion detector for use with a sealless centrifugal pump. The corrosion detector having a corrosion coupon at one end of the detector. The corrosion coupon being formed of the same material as the pump containment shell and having a thickness approximately two thirds the thickness of the containment shell. The corrosion detector is preferably installed in a bore in the pump discharge flange such that the corrosion coupon is exposed to the velocity of the pumped fluid. A detector is mounted within the corrosion detector to detect any leakage of the pumped fluid through the corrosion coupon. The corrosion coupon is designed so that this leakage will occur before the containment shell has failed or begun leaking due to corrosion.
