    摘要： A variable speed pumping system including a variable speed pump, a remote user device, and an auxiliary device is provided. The variable speed pump includes a motor, a drive, a housing including a drive cover, and an onboard controller. The onboard controller includes a plurality of buttons formed in the drive cover, a touchscreen interface positioned on the drive cover, a main circuit board including a non-transitory computer readable medium, the main circuit board being electrically coupled to the touchscreen interface, the motor, and the drive, a wireless communication unit electrically coupled to the main circuit board, and a selectively removable IO expansion module. The onboard controller is configured to control one of a flow rate of the pump or a speed of the motor for a period time and actuate the auxiliary device based on input received on one of the onboard controller or the remote user device.

    摘要： Embodiments of this application provide a centrifugal pump. The centrifugal pump includes a pump casing and a first drive mechanism, a second drive mechanism, a pump shaft, and an impeller that are disposed in the pump casing. The pump casing includes a first chamber and a second chamber that are connected. An axis of the pump shaft coincides with axes of the first chamber and the second chamber. An inner diameter of the second chamber is greater than that of the first chamber. The impeller is connected to an end of the pump shaft. The first drive mechanism and the second drive mechanism are connected to the pump shaft and located on a side, away from the impeller, of the pump shaft. The first drive mechanism is configured to drive the pump shaft to rotate. The second drive mechanism is configured to drive the pump shaft to move along the axis. The impeller is driven by the pump shaft to rotate in the first chamber or the second chamber. The centrifugal pump provided in the embodiments of this application can meet requirements of high head and high reliability of a pump at the same time.

    摘要： A canned motor device includes a base (10), a fixed seat (20), a motor unit (30) and a motor cover (40). Each of the base (10) and the fixed seat (20) is formed in a shape of a hollow cylinder that surrounds an axis (L). The base (10) has an inner base surface (14) surrounding the axis (L) and defining an accommodating space (13) . The fixed seat (20) is disposed in the accommodating space (13) and has an inner seat surface (23), an outer seat surface (24), a plurality of recesses (25) and a plurality of first heat-dissipating fins (26) . The recesses (25) are indented from the outer seat surface (24) and extend toward the inner seat surface (23) . Each of the first heat-dissipating fins (26) is located between two adjacent ones of the recesses (25).

    摘要： To provide a rotor for electric water pumps in which a sliding bearing formed of a thermoplastic resin composition can be produced at a low cost and has superior low friction and low wear property, and an inner diameter of the sliding bearing is hardly contracted by the insert-molding. A rotor 1 used for electric water pumps has a main body 2 that supports an impeller of the pump, a sliding bearing 3 that rotatably supports a shaft, and a magnet 4 disposed to face a stator. The sliding bearing 3 is an annealing treated body of a polyphenylene sulfide resin composition. The polyphenylene sulfide resin composition contains 5-30 vol% of carbon fiber, 1-20 vol% of polytetrafluoroethylene resin and 1-30 vol% of graphite relative to the whole volume of the polyphenylene sulfide resin composition. The main body 2 is an injection-molded body disposed by insert-molding a thermoplastic resin composition, which is different from the polyphenylene sulfide resin composition, at an outer diameter side of the sliding bearing 3.
