Embodiment 1

[0022] Embodiment 1, a method for repairing a large-scale equipment thrust plate on site, comprising the following steps:

[0023] (1) Remove the thrust pad cover and thrust pads on the damaged thrust disc to expose the damaged thrust disc;

[0024] (2) Remove the small drag tool holder on the C630 lathe, fix it to the damaged thrust plate, adjust the position of the small drag frame, and install a suitable turning tool;

[0025] (3) Use the motor to drive the rotor on one side of the damaged thrust disc to rotate, so that the damaged thrust disc rotates, and use the turning tool to perform fine turning on the damaged part of the rotating thrust disc, that is, use the turning tool to perform fine turning on the damaged part of the thrust disc. Turning;

[0026] (4) Apply a layer of lubricating oil to the thrust plate after cutting, and then install the thrust pad shield and thrust pad removed in step (1) on the thrust plate, and then it can be used normally.

Embodiment 2

[0029] Embodiment 2, the same part as embodiment 1 is not repeated, and the difference with embodiment 1 is:

[0030] Described lubricating oil is antirust lubricating oil, and described antirusting lubricating oil is made of the raw material of following parts by weight:

[0031] 120 parts of base oil, 25 parts of hydrogenated palm oil, 8 parts of nonylphenol polyoxyethylene ether, 6 parts of modified ceramic rubber powder, 2.5 parts of aromatic modified terpene resin, 2 parts of triglyceride, 1.5 parts of propolis extract, 0.8 parts of crospovidone, 0.8 parts of dipentaerythritol, 0.5 parts of methyl carbamate, and 1.5 parts of nano titanium dioxide.

[0032] The modified ceramic rubber powder is prepared by modifying ceramic fiber, organosilicon resin, sepiolite fiber powder, and polyurethane emulsion. The modification method is: adding sepiolite fiber powder, organosilicon resin After fully mixing, use microwave reflux with frequency 2250MHz and power 800W for 10-20min, t...

Abstract

The invention discloses an on-site repair method for a thrust disc of large equipment. The on-site repair method comprises the following steps: (1) removing a thrust tile shield and a thrust tile which are arranged on a damaged thrust disc to expose the damaged thrust disc; (2) dismantling a small tool holder on a C630 lathe, fixing the small tool holder to the damaged thrust disc, adjusting the position of the small tool holder, and installing an appropriate turning tool; and (3) utilizing a motor to drive a rotor on one side of the damaged thrust disc to rotate, so that the damaged thrust disc rotates, and the turning tool is utilized to perform fine turning on damaged portions of the rotating thrust disc, namely, turning is performed on the damaged portions of the thrust disc through the turning tool. The design is simple to operate, strong in comprehensive practicability and easy to popularize and use.

Description

Technical field: [0001] The invention relates to a thrust disk repair method, in particular to a large-scale equipment thrust disk repair method on site. Background technique: [0002] The four-in-one unit with an annual output of 150,000 tons of nitric acid broke down due to improper operation during operation. After inspection, it was found that the thrust tile of the nitrogen oxide compressor was damaged, and the upper thrust plate of the rotor was damaged. According to the routine maintenance plan, it is necessary to open the upper cover of the nitrogen oxide compressor, lift out the rotor, and send it to the manufacturer for finishing treatment, which is time-consuming and laborious, which increases the parking time and affects production efficiency. Invention content: [0003] The existing technology is difficult to meet people's needs. In order to solve the above-mentioned existing problems, the present invention proposes a method for on-site repairing of large-scal...
