    Abstract: A process for optimizing the design of a semi-open centrifugal pump impeller involves the steps of, reducing the number of long blades and adding a medium length splitter blade and a short length splitter blade having varying circumferential distances between any two optimized long blades. Each medium length and short length splitter blade have the same outlet position, profile and thickness as the optimized long blade; however, the medium length and short length splitter blades have different inlet positions relative to the optimized long blade. The long blade, medium length splitter blade and short length splitter blade are arranged in circumferential sequence along the direction of rotation of the impeller. This optimization improves various problems arising from the original semi-open centrifugal pumps, including low efficiency, significant loss at the inlet, inlet cavitation, separation of boundary layers at the blade inlets, narrow lift range of the dead point and excessive noise.

    Abstract: The present disclosure provides a two-stage cavitation generator for organic wastewater treatment, including a shrouded impeller, a stator, and a rotor. The shrouded impeller includes a front cover plate, blades, and a rear cover plate. Several blades are evenly distributed between the front cover plate and the rear cover plate. A working surface of the blade is an arc surface, and a back of the blade protrudes locally, so that a flow channel between the back of the blade and a working surface of its adjacent blade is narrowed locally, forming a throat structure. An outlet of the shrouded impeller is provided with the stator and the rotor, and the stator is located at an outer edge of the front cover plate and fixed on an inner wall of a volute. The rotor is mounted on the rear cover plate.

    Abstract: A gear-hydraulic-rhombic pyramid integrated multi-mode hybrid transmission device includes an input assembly, a hydraulic transmission mechanism, a front planetary gear mechanism, a rhombic pyramid-type continuously variable transmission mechanism, a rear planetary gear mechanism, an output assembly, a clutch assembly, and a brake assembly. The clutch assembly connects an output end of the input assembly to an input end of the hydraulic transmission mechanism and an input end of the front planetary gear mechanism. The clutch assembly connects an output end of the hydraulic transmission mechanism to the front planetary gear mechanism and the rear planetary gear mechanism. The clutch assembly connects the front planetary gear mechanism, the rhombic pyramid-type continuously variable transmission mechanism, the rear planetary gear mechanism, and the output assembly in sequence. The clutch assembly and the brake assembly provide a continuous transmission ratio between the input assembly and the output assembly.
