POWER MANAGING PUMPING SYSTEM
A pump system comprises a controller operatively connected to an electrical circuit, a first pump and a second pump operatively connected to the controller, an inverter operatively connected to the controller, and a battery operatively connected to the inverter. The pumps can operate individually or simultaneously. One pump operates individually with power supplied by either the electrical circuit or the battery. The pumps operate simultaneously with power supplied to one pump by the electrical circuit and to the other pump by the battery if electrical circuit power is available. The pumps operate simultaneously with power supplied by the battery if electrical circuit power is not available. The pump system protects against at least one of failure of one of the first pump and the second pump, failure of the electrical circuit, and inflow exceeding a capacity of one of the first pump and the second pump.

BACKGROUNDSump and sewage pump systems are used to pump unwanted fluids (e.g., water and waste) out of a tank, sump, or reservoir. Such systems typically implement pump switching devices to activate and deactivate the pump(s) as needed. Typical pump switching devices use sensing methods such as floatation-based switches with tethered float switches, vertical floats guided by rods, or orienting devices to indicate when to activate and deactivate the pump(s).
Failure in sump and sewage pump systems is typically caused by at least one of several reasons including pump failure, loss of power, level sensor failure, and/or inflow rate exceeding pump capacity. Common systems used to help protect against flooding due to failure include pump systems with primary and secondary pumps, battery backup systems with DC pumps, and battery backup systems with inverters.

In one embodiment, a pump system comprises a controller operatively connected to an electrical circuit, a first pump and a second pump operatively connected to the controller, an inverter operatively connected to the controller, and a battery operatively connected to the inverter. The first and second pumps are configured and arranged to operate individually or simultaneously.

Other embodiments and many of the intended advantages of embodiments will be readily appreciated as they become better understood by reference to the following detailed description. In accordance with common practice, the various described features are not drawn to scale but are drawn to emphasize specific features relevant to the present disclosure. Reference characters denote like elements throughout the Figures and the text.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration embodiments in which the disclosure may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” “leading,” “trailing,” etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
It is to be understood that other embodiments may be utilized and mechanical changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense.
Example embodiments of the disclosure generally provide a pump system including first and second pumps operatively connected (e.g., electrically connected) to an electrical circuit (e.g., from main power supply to the building) and a backup battery via a controller. Only a single electrical circuit is needed. An inverter is used to convert direct current (DC) from the battery to alternating current (AC) for use by either or both pumps. The pumps can be operated individually or simultaneously, with power being supplied by the main electrical circuit and/or the battery and the inverter. Therefore, this system can protect against at least one of pump failure, power failure, and inflow exceeding a single pump's capacity.
An example pump system 600, illustrated in
In an example, during normal operation when the main power (incoming power) from outlet 605 to line power input 634 is “on”, the system 600 will operate the first pump 601 through first pump output 650 to maintain sump pit water or waste removal demands along with ensuring that the battery 642 charge is maintained. The charging rate of the battery 642 will vary depending on how much power is being used to operate the first pump 601. When the first pump 601 is running, the charging rate of charging circuit 640 may be reduced or the charging turned off to balance the controller power usage to the available incoming power from outlet 605. When the first pump 601 is not running, the balance will shift so that all available incoming power from outlet 605 will be used to maintain the battery charge. If the incoming water or waste demand exceeds the capacity of the first pump 601, the controller assembly 608 will start the second (backup) pump 602 through second pump output 652, which will be powered by the battery 642 and the inverter 644 while the first pump 601 is powered by the incoming power from outlet 605. Any excess incoming power from outlet 605 may be used to charge and/or maintain the battery 642. Although a first pump 601 and a second pump 602 are shown and described, the controller assembly 608 could be designed for monitoring pump usage and could alternate first usage, when only one pump is used, between the first pump 601 and the second pump 602, so that both pumps accumulate similar use. This is done to prevent one pump from being used more frequently and fail prematurely. It is also done to prevent a pump from being idle for too long and seizing up. The ability to utilize alternating usage of the pumps can assist in maintaining a reliable system and ensure that both pumps are operating optimally.
Although one pump can operate with incoming main power on line power input 634 and one pump can operate with battery 642 and the inverter 644 power at the same time, the controller assembly 608 can be designed to operate one or both pumps on battery power, if needed. In an example, during operation if the incoming power from outlet 605 to the controller assembly 608 is disrupted (e.g., due to power outage, tripped electrical breaker, or accidental unplugging of the controller assembly 608), the controller assembly 608 can switch to battery operation. The system 600 can then be maintained by battery power only using one or both pumps. The system 600 can be designed to ensure it optimizes the use of battery power to run the pump(s) to meet incoming water or waste demands.
Optional features and optional configurations could be used. The pump system could be designed to use various inputs through sensor input(s) 636 to determine the status of water or waste levels in and around the pumping chambers. Examples include, but are not limited to, a float switch 601a, 602a associated with each respective pump 601, 602; a high-level alarm float switch 603; a floor sensor 604; a pressure sensor 606; a conductive probe 607; and a capacitance switch 613. As illustrated in
In another example pump system 700, illustrated in
The controller can operate in different ways to conserve power, which can also reduce heat generation. The battery charger can be turned off when not in use for charging the battery (e.g., when the battery is fully charged). The battery charger can stop charging the battery or charge the battery at a lower level during use of the battery (e.g., while at least one pump is running off the battery). The controller can reduce the charge rate and/or turn off the charger in order to keep the system's AC power consumption within allowable limits. The inverter can be turned off when not in use (e.g., while none of the pumps are running off the battery) to conserve battery power and extend the battery's useful charge. The pump(s) can be used for selected periods of time and then turned off for selected periods of time. There may be other ways power can be conserved and heat generation can be reduced. Some examples are illustrated in Table 1 and
