The pump device has a first inner cavity and a second inner cavity; the pump device has a first housing and a second housing, the first housing partially covers the rotor assembly, the second housing at least partially covers surrounds an outer periphery of the stator assembly; the first housing and the spacer are fixedly connected by means of welding, and the connection position between the first housing and the spacer is sealed; the second housing and the spacer are fixedly connected by means of welding, and the connection position between the second housing and the spacer is sealed; the spacer comprises a first flange portion and a cylinder portion.

Abstract: A charging method can include: obtaining a charging current for each of a plurality of loads, where each load includes a battery; and adjusting a charging voltage received by each load according to a variation of each charging current, in order to control the charging voltage to vary along with a battery voltage with a highest battery voltage of the plurality of loads in real time.

Abstract: A complete set of tension backup device for carbon fiber wire, consisting of a backup tension device, a performed armor rod, a parallel hanging plate, an adapter base, a wire drawing device, a support damper clamp, a U-shaped pulling ring, a triangular hanging plate, and a tensioning device. The backup tension device is a backup strain clamp in a wedge-shaped structure. The support damper clamps are provided on carbon fiber split wires between an original strain clamp and the backup tension device, and arranged at intervals of 3-4 meters.

Abstract: The present disclosure provides a data processing system, method and device. The system includes a control component and a plurality of computing subcomponents coupled to the control component. The plurality of computing subcomponents respectively processes sample subsets of a sample data set under instruction of a processing procedure in the control component. For one of the plurality of computing subcomponents, at least one data element is configured to output the sample subsets of the sample data set in sequence to an embedding element based on the processing procedure in the control component. At least one embedding element is configured to receive a sample subset based on the processing procedure in the control component, map sample data in the sample subset to a multi-dimensional space based on a mapping parameter to obtain a multi-dimensional sample subset, and output the multi-dimensional sample subset to at least one backend element.
