Anti-Entrapment and Anti-Deadhead Function
In accordance with one aspect, the present disclosure provides for systems and methods for controlling a pumping system for at least one aquatic application. The pumping system can include a pump, a motor coupled to the pump, an interface associated with the pump designed to receive input instructions from a user, and a controller in communication with the motor. The controller determines a blockage condition based on a power consumption value of the motor, and can further include an auto-restart function that is designed to allow the pump to automatically restart after detection of the blockage.
Fan motor controller for use in an air conditioning system
One aspect provides an air conditioning system that includes a compressor housing, a motor having fan blades rotatably coupled thereto and located within the compressor housing. The motor has a rotation sensor associated with it that is configured to sense a rotation of the fan blades. This embodiment further comprises a controller coupled to the motor and is configured to increase a torque of the motor when the rotation sensor indicates that the fan blades are not rotating after an on command signal is received by the motor.
Detecting and utilizing a rise rate for sump pump system control
A sump pump system detects backflow from an outlet pipe in a sump pump system and implements control of the sump pump in light of the detected backflow (or lack thereof). The sump pump system may detect the backflow (or lack thereof) by detecting and comparing water rise rates in a sump basin before activation or engagement of the sump pump (e.g., immediately before the pump starts pumping) and after the pump has disengaged or deactivated (e.g., immediately after the pump stops pumping). The rises rates may be detected via sensors configured to detect motion or acceleration (e.g., accelerometers, inertial measurement units, or force acceleration sensors) placed in the sump basin such that detect motion of water in the basin corresponding to changing water levels.
Determining and utilizing a desired frequency for a mechanical shaker for a sump pump system
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.
PUMP DEVICE HAVING A DETECTION DEVICE
The invention relates to a pump device having a pump (8) and an energy supply device (5, 18), wherein the pump has a conveying element (9, 11) which conveys a fluid by means of supplied energy, wherein the pump has a transport state and an operating state, and wherein at least one first element (9, 9a, 10, 10, 11) of the pump has a different shape and/or size in the transport state than in the operating state. The operating safety of such a pump device is increased by a detection device (12, 20, 21, 22, 23, 24, 25, 27, 28, 29) which detects whether at least the first element is in the operating state with respect to shape and/or size by means of a sensor.
Method of controlling a pump and motor
Embodiments of the invention provide a variable frequency drive system and a method of controlling a pump driven by a motor with the pump in fluid communication with a fluid system. The drive system and method can provide one or more of the following: a sleep mode, pipe break detection, a line fill mode, an automatic start mode, dry run protection, an electromagnetic interference filter compatible with a ground fault circuit interrupter, two-wire and three-wire and three-phase motor compatibility, a simple start-up process, automatic password protection, a pump out mode, digital input/output terminals, and removable input and output power terminal blocks.
Anti-entrapment and anti-dead head function
In accordance with one aspect, the present invention provides a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, an interface associated with the pump designed to receive input instructions from a user, and a controller in communication with the motor. The controller determines a blockage condition based on a power consumption value of the motor, and further includes an auto-restart function that is designed to allow the pump to automatically restart after detection of the blockage.
SUMP PUMP SMART HOME INTEGRATION
Described methods and systems user to manually activate or engage the pump from a remote location and/or to monitor the state of the sump pump (e.g., the water level, the pump condition, pipe conditions, etc.) when located at a remote location relative to the sump pump. A sump pump system may implement sensors configured to detect motion or acceleration of a sensor disposed in water in the sump basin or disposed on a sump pump or pipe. The sump pump system may analyze data from these sensors to identify diagnostic metrics or values that are transmitted to a user's user interface device, thereby notifying a user of conditions such as a stuck impeller, a blocked pipe, a dry pumping pump, etc.
DETECTING AND UTILIZING WATER VIBRATIONS IN SUMP PUMP SYSTEM CONTROL
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.
PUMP DEVICE HAVING A DETECTION DEVICE
The invention relates to a pump device having a pump and an energy supply device, wherein the pump has a conveying element which conveys a fluid by means of supplied energy, wherein the pump has a transport state and an operating state, and wherein at least one first element of the pump has a different shape and/or size in the transport state than in the operating state. The operating safety of such a pump device is increased by a detection device which detects whether at least the first element is in the operating state with respect to shape and/or size by means of a sensor.
