Concrete slump detection device
PendingCN121955354Asmall footprintReasonably placedFlow propertiesPreparing sample for investigationStructural engineeringConical cavity
The invention discloses a concrete slump detection device, and relates to the technical field of concrete detection, the concrete slump detection device comprises a cone, a conical cavity is formed in the cone, the conical cavity is filled with a material, and the cone is equally divided into a left part and a right part; the flat plate seals the lower end of the conical cavity; the main beam is used for connecting the vehicle with the cone and can also connect the vehicle with the flat plate; the translation assembly drives the left part and the right part to translate and rotate back to back; the folding assembly drives the flat plate to rotate to save the space occupied by the flat plate. The cement mixer has the beneficial effects that the cone can be divided into two parts to be installed at the tail of the cement mixer under the action of the translation assembly, the flat plate can be installed at the tail of the cement mixer under the action of the folding assembly, the size is reduced, and transportation is convenient.

Induction motor and scroll compressor
ActiveCN121841040Bevenly distributedReduce stray lossesRotary/oscillating piston combinations for elastic fluidsMagnetic circuit rotating partsElectrical conductorElectric machine
This invention provides an induction motor and a scroll compressor, relating to the design and manufacturing of scroll compressors. The induction motor includes a stator core and a rotor core. Multiple turns of circular enameled wire and insulating paper are placed in the first conductor slot of the stator core. The circular enameled wire is composed of insulating enamel, copper, and aluminum. Cast aluminum is placed in the second conductor slot of the rotor core. This invention increases motor efficiency and reduces cost by limiting the relationships between Kq, Ks, Kf, and Kd to 10.216 ≤ [Kf×(1-Kd)+Kq×Ks] / (Kf×Kd) ≤ 16.844. Furthermore, by imposing dimensional constraints on the first conductor slot, the second conductor slot, and the heat dissipation slot, motor efficiency is further increased and motor cost reduced.
