A sealing assembly process method for an eddy current brake stator assembly

Abstract

The invention provides a seal assembling technique of an eddy current brake stator assembly. The seal assembling technique of an eddy current brake stator assembly includes the steps: welding and assembling components of the stator assembly part, after welding, cleaning the internal cavity, and adding insulation paste in the bottom layer of the cavity according to the technique configuration demand; waiting until the insulation paste is solidified to 70%, putting a coil in the cavity, filling the cavity with organosilicon gel until the technique demand is satisfied, guaranteeing that the internal and external gaps of the coil at one side are completely filled with the organosilicon gel, then installing the corresponding magnetic pole to weld and assembly, and completing stator assembly. The seal assembling technique of an eddy current brake stator assembly has the advantages of being stable and reliable in technique, reducing the link of the cooling system airtight experiment, reducingthe links of detection and repair, replacing filling of filled mud, being labour saving and time saving, reducing the time of delivery of products, and improving the stability of products.

Description

technical field [0001] The invention belongs to supporting equipment of oil drilling rigs, and relates to a production process of an eddy current braking stator assembly for auxiliary braking of deep sea drilling rigs or land drilling rigs. Background technique [0002] Eddy current brakes are used as auxiliary brakes for deep-sea drilling rigs or land drilling rigs. They can be supplied as a complete set with the winch, or as a separate component for the drilling rigs already used in the mine. The working principle is as follows: [0003] When a moving ferromagnetic body passes through a fixed inhomogeneous magnetic field, a circulating current is induced in the conductor on a plane perpendicular to the direction of the magnetic field, which is called an eddy current, and this eddy current will cause a magnetic field. The polarity of the magnetic field Just opposite to the polarity of the original fixed magnetic field, the two magnetic fields with opposite polarities will r...

AI Technical Summary

Problems solved by technology

However, there are many problems in this method. 1. The main material is a casting. When the compressed air enters the cavity, the pressure is too high and the pores of the casting itself will leak, which will affect the judgment of the leakage point.

2. The weld to be detected is two parallel welds. When observing the leak point, it is impossible to know which weld is leaking, which will affect the repair parameters

3. This method needs to be tested repeatedly, time-consuming and labor-intensive, the effect is poor, and human factors have a great influence

This problem leads to a long and uncontrollable product production cycle, the human factors of the test results are too large, and the accuracy of the test results is poor, which greatly restricts the quality of the product.
