Embodiment Construction

[0011] Such as figure 1 The structure of the simple bracket used in the method of the present invention is to include a mounting platform 2 provided with legs 3, and a V-shaped groove is provided on the upper surface of the mounting platform 2, and the two slopes in the V-shaped groove are respectively along the axis A cylinder 1 is placed in the direction, and the rotor to be repaired is placed on the two cylinders 1.

[0012] The field maintenance method of the present invention is implemented according to the following steps:

[0013] Step 1. After repairing the wear-resistant layer of the rotor to be repaired, place the rotor on two simple axially aligned supports. The rotor shaft 4 and the two cylinders 1 are kept in tangential contact with each other for static Balance test, rotate the rotor that needs to be repaired, repair the counterweight according to the static balance test results, until it reaches the static balance requirement of 10-20 grams;

[0014] Step 2. Put the ...

Abstract

The invention discloses an on-site repairing method for an SJ type air-intake sintering system. The on-site repairing method comprises the following steps of: 1) after additionally welding a wear-resisting layer of a to-be-repaired roller, placing the roller on two simple brackets with aligned axial directions, performing a static balance test, additionally welding a counterweight block according to a result of the static balance test, till meeting 10-20g static balance demand; and 2) assembling the roller meeting the static balance demand on a host machine, starting the host machine, utilizing a portable dynamic balancing instrument to detect a numerical value of the dynamic balance of the roller, and adjusting the counterweight block till being within a dynamic balance scope meeting technical demands. According to the on-site repairing method provided by the invention, the on-site repairing is realized; the method is simple; less equipment is used; the repairing efficiency is high; a set of rollers can be used for 60-70 months, after the wear-resisting layer is additionally welded for three times, the blade is replaced for three times and the impeller is finally replaced; the repairing cost of a user is greatly saved; and the use efficiency of the equipment is increased.

Description

Technical field [0001] The invention belongs to the technical field of mechanical maintenance, is mainly aimed at the SJ type series sintered air compressor, and relates to an on-site maintenance method of the SJ type air intake winding system. Background technique [0002] SJ series sintering air compressors are widely used in the smelting industry. Due to the different effects of air intake, the wear of the rotor wear layer generally needs to be repaired once in 3-4 months. Damage may cause damage to the entire unit and cause major accidents. [0003] The existing repair method is to remove the rotor and transport it back to the manufacturer for repair, which will cause long turnaround time for the user, packaging and transportation back and forth, time-consuming, laborious and costly; or some users simply replace it when it is not in compliance with the regulations. The rotor causes unnecessary waste. Summary of the invention [0004] The purpose of the present invention is to ...
