The application provides a double-suction centrifugal pump with a built-in driving mechanism, and belongs to the field of fluid delivery and special motor combination. The application comprises a split pump shell, an impeller, a pump shaft and a built-in driving mechanism. The pump shaft is fixed inside the pump shell, and two impellers are symmetrically sleeved on the pump shaft and can rotate around the pump shaft. The built-in driving mechanism is an axial flux motor structure, comprising a magnet and an induction coil. The induction coil is fixed on the pump shaft and located between the two impellers, and the magnet is embedded in each of the two impellers. A rotating alternating magnetic field is generated by electrifying the induction coil, which drives the impellers with the magnets on both sides to rotate synchronously around the stationary pump shaft, so as to realize the delivery of fluid. The application realizes the self-balancing of axial magnetic force, significantly reduces the axial load of the water-lubricated bearing, and prolongs the service life of the bearing and the whole machine.

This invention relates to a self-balancing multistage pump with axial force, solving the problems of high energy consumption, short lifespan, and poor operational stability caused by the large axial force generated by the equal outer diameter of the front and rear cover plates and a specific speed (ns>300) in existing technologies. The technical solution includes a pump body, an impeller string housed within the pump body, and several sets of impeller units within the impeller string. The key feature is that each impeller unit includes a guide shroud, an impeller housed in the guide cavity of the guide shroud, and the impeller comprising a front cover plate, a rear cover plate, and blades disposed between the front and rear cover plates. The outer diameter of the front cover plate is larger than that of the rear cover plate. The front cover plate mates with the bottom of the guide cavity and with the open portion of the guide cavity. Its effects are: by using an impeller with a front cover plate area larger than the rear cover plate area, and in conjunction with the guide shroud, self-balancing of the impeller axial force is achieved, making the pump operation more stable and reliable, significantly reducing power consumption, greatly improving social and economic benefits, and achieving the goal of energy conservation and emission reduction.

The invention discloses a capacitor voltage self-balancing method of a three-level dual-active bridge converter. Different from the conventional balance control method, the invention provides an improved switch sequence which realizes the self-balance of the capacitor voltage from the modulation level. In the improved switch sequence, when the polarity of the output voltage of the NPC full bridge is not changed, only a single capacitor is used for energy exchange. The unbalance of the capacitor voltage enables the current of the transformer to be superposed with an asymmetric current component, thereby facilitating the balance of the capacitor voltage. The improved switch sequence does not change the original output voltage characteristics of the NPC full bridge. And meanwhile, additional capacitor voltage balance control is not needed, so that the complexity of a converter control system is greatly reduced, and the robustness of the converter is improved.
