发电机定子线棒主绝缘高压水剥除工艺及性能研究OA

Regarding the low efficiency and high labor intensity of the traditional manual stripping of the main insulation of wire rods,high-pressure water jet stripping is adopted and the process is optimized.The performance of the stripped electromagnetic wires is characterized using a metallographic microscope,Brinell hardness tester,XRD,etc.The surface resistance of the electromagnetic wire is tested,and the quality of the filtered medium water and the size of solid suspended particles are analyzed.The results show that the optimal process parameters for stripping the main insulation of the wire rod with high-pressure water are a jet angle of 30°～60°,a standoff distance of less than 30 cm,and a pressure of 20～30 MPa.There is no significant difference in the surface morphology,copper phase composition,surface hardness,and surface resistance of the electromagnetic wire surface compared to the electromagnetic wire obtained by manual stripping method.The medium water used can be directly discharged or reused after being filtered through a 1200-mesh filter cloth.The overall process is safe and reliable,and this method has good promotion and application value.
