4results about How to "Uniform loss" patented technology

The system comprises a group control center, a plurality of groups of water chilling units, a plurality of groups of chilled water pumps, a plurality of groups of cooling towers, a plurality of groups of cooling water pumps, a data acquisition module, a data processing module and a control module, the data acquisition module is used for acquiring operation parameters of multiple groups of water chilling units, multiple groups of chilled water pumps, multiple groups of cooling towers and cooling water pumps in real time; and the health degree prediction module is in signal connection with the data acquisition module and is used for receiving the operation parameters of the data acquisition module. Compared with the prior art, the system has the advantages that the health degree loss among similar equipment is balanced through the multi-objective optimization module, premature damage of part of equipment due to long-term high-load operation is avoided, equipment clusters are relatively coordinated, the overall service life is prolonged, in addition, the equipment runs in a high-efficiency interval as much as possible, and the service life is prolonged. And energy waste caused by faults, low-efficiency operation or simultaneous operation of unnecessary equipment is reduced, so that the overall operation energy consumption is reduced.

This invention relates to a polishing device for the outer surface of aluminum alloy profiles, comprising a processing table with several fixed horizontal plates mounted on its top. A first conveyor frame and a second conveyor frame are mounted on the left and right ends of the top of the processing table. Workpieces are placed on the first and second conveyor frames. The invention includes a lifting assembly, a translation assembly, a longitudinal polishing mechanism, and a transverse polishing mechanism. The combined use of the lifting assembly and the longitudinal polishing assembly allows the longitudinal polishing assembly to move up and down. The combined use of the translation assembly and the transverse polishing mechanism allows the transverse polishing assembly to move back and forth horizontally. This avoids excessive localized wear caused by the sisal wheel being in the same position during polishing, resulting in uniform surface wear of the sisal wheel and reducing material loss.

The application discloses a valve grinding device with self-adjusting taper, which comprises a mounting unit, a connecting head arranged at one end of a mounting rod, and a mounting plate arranged at the other end of the mounting rod. The device further comprises an adjusting unit, a nut screw-connected with the mounting rod, and an adjusting assembly rotatably arranged at the bottom surface of the nut. The device further comprises a grinding unit, a swing assembly movably arranged on the mounting plate, a roller pin assembly detachably arranged on the swing assembly, a pushing-out assembly arranged on the swing assembly, a pressing assembly arranged in the swing assembly, and a pushing assembly arranged in the swing assembly. The valve grinding device with self-adjusting taper can change the angle of the swing assembly by rotating the nut and driving the swing assembly through the adjusting assembly, and can change the angles of the multiple grinding units simultaneously. In the rotating grinding state, the roller pin assembly can process and polish surfaces with different angles, and can adapt to valve seats with different angle grinding requirements, and the roller pin assembly can be uniformly worn.

The application relates to the technical field of optical coating, and particularly discloses a kind of depolarization spectrometer prism coating film system, coating film method and application thereof, the film system includes 28 layers of dielectric film layers, and the order from inside to outside is MHML MHMLMHMLMHMHMLMHMLMHMHML, wherein the M layer is Al2O3, the H layer is TiO2, and the L layer is SiO2.The application solves the polarization error caused by the current conventional depolarization spectrometer prism and the problem of uneven energy distribution in the multi-stage light path.In addition, the coating film method realizes high consistency between the actual coating process and the theoretical design by fine control of key process parameters, and ensures that the film system performance is stable and up to standard.
