Abstract

The invention belongs to the technical field of mechanical loading devices, and particularly relates to an electromagnetism dynamic loading device to solve the problem that according to a method for eliminating or balancing parallel axial force of axes in the prior art, the dynamic axial force cannot be balanced or exerted or offset. The electromagnetism dynamic loading device comprises an annular electromagnetic end cover and a flange connected with the electromagnetic end cover. An annular coil groove is formed in the electromagnetic end cover and internally provided with a wire ring, and direct current flows through the wire ring. An electromagnetic iron core is fixedly connected to the inner side of the electromagnetic end cover. The electromagnetism dynamic loading device overcomes the defects that according to the existing axial force balancing equipment and device, the dynamic axial force cannot be rapidly, effectively, easily and conveniently balanced, and the manufacturing process is simple and easy to perform; the structure of the electromagnetism dynamic loading device is optimized, and the effect of balancing or exerting or offsetting the large axial force can be achieved. The electromagnetism dynamic loading device has high engineering value in preventing dynamic axial force produced in operation of turbo machines and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical loading devices, and in particular relates to an electromagnetic dynamic loading device. Background technique [0002] When most impeller machines are running, due to the asymmetric pressure distribution of the fluid on the impeller, the rotating parts will be subjected to an axial force parallel to the axis. In order to ensure the normal operation of this type of equipment, measures must be taken to eliminate or balance the axial force. At present, there are many techniques for balancing the static axial force, while the balance of the dynamic axial force and comprehensive consideration of other constraints (including bearings and machinery) Sealing) and other issues are less studied; no relevant patented technology and equipment research. [0003] The main implementation methods and characteristics of static axial force balance are summarized as follows: [0004] 1) Thrust bearings are used...
