Problems solved by technology

[0003] As a basic part widely used in high-end equipment, seals have a high wear rate. For worn seals, they are usually removed for replacement or repaired. The existing repair methods for seal wear are easy to repair. Due to data measurement problems, the size of the repaired seal is abnormal and the performance is degraded. Therefore, a repair method for seal wear in high-end equipment remanufacturing is proposed.

Embodiment 1

[0032] see figure 1 , the present invention provides a technical solution: a method for repairing wear and tear of seals for high-end equipment remanufacturing, comprising the following steps:

[0033] S1. Remove the worn seal, place the removed seal on a flat horizontal workbench, align the seal on the workbench to form a circle, and fix it on the workbench;

[0034] S2. Measure the size and wear amount of each part of the seal, respectively measure the overall size and wear amount of the seal, and compare the measured data with the production data of the seal. The measurement error is within 0.1mm as qualified;

[0035] S3. Calculating the processing complement amount of each part of the seal, calculating the processing complement amount of each part of the seal according to the measurement results of the seal and the production data of the seal, and comparing the calculation result with the wear amount;

[0036] S4. Calculate the removal amount of the processed part, and c...

Abstract

The invention discloses a sealing position abrasion repairing method for high-end equipment remanufacturing. The method comprises the following steps that S1, an abraded sealing part is detached; S2,the size and the abrasion loss of each part of the sealing part are measured; S3, the machining complementation amount of each part in the sealing part is calculated; S4, the cutting amount of the machined position is calculated; S5, the complementation position of the sealing part is preheated; S6, hot welding complementation is conducted on the abraded position of the sealing part; S7, redundantportions on the sealing part are cut off; S8, the sealing part is subjected to cooling and standing; S9, the size of the repaired sealing part is detected; and S10, the performance of the repaired sealing part is tested. When the method is used, more accurate data can be measured when the method is used for repairing the sealing part by measuring all the parts of the sealing part, measuring the abrasion loss of the sealing part, measuring the machining complementation amount and the cutting amount of the sealing part and comparing the measurement and calculation result with production data.
