The motor rotor shaft of the steel industry is worn out
The rotor shaft of a motor in an iron and steel industry is worn out. The specific conditions are as follows: wear position: rolling bearing position and sealing position on the transmission system side; Wear condition: the rolling bearing position is worn 0.5mm, and the total wear width is 75mm. The sealing position is worn like a pipe groove, with a wear of 0.3mm and a total wear width of 30mm; speed ratio: 1495r/min. Because we have used our technology to repair the shaft wear of the continuous casting machine before, and the machine and equipment have been used until now after repair, so please call us to ask if you can repair the shaft wear of the motor.
Solay carbon nano composite material repair technology is the use of raw materials unique physical properties and targeted repair processing technology to repair a variety of shaft wear problems. As for the wear condition of the rotor shaft of the motor, according to the relevant data such as machine control parameters, photos and drawing proportion of parts provided by the company, through careful analysis by the core professional and technical personnel of everyone's planning scheme, we confirmed the successful case of repairing the wear of the rotor shaft of the motor before merging, and confirmed the technical process of this repair. The planning scheme given by everyone can meet the operation regulations of the repaired machine.
In addition, for the repair of motor rotor shaft wear, Solley carbon nanocomposite material has excellent mechanical processing characteristics, to meet the production and processing regulations of turning, milling, planing and grinding, and there is no internal stress hazard in the repair. And high reliability of material performance, can extend the life of weapons and equipment, so that maintenance more peace of mind.
The rotor with large original unbalance will produce unpredictable risks after high-speed operation. The dynamic unbalance of the rotor is produced in the production and processing of the rotor. From the perspective of the rotor manufacturing process, it is an important reason for the dynamic unbalance of the rotor. Generally, what processing process will cause the original unbalance of the rotor to be slightly larger? Let me know about it together with the centralized dynamic balancing machine.
1. Rotor iron core silicon steel sheet and extrusion: sampling inspection of silicon steel sheet thickness, silicon steel sheet burr, extrusion tightness and unbalance. The key is to limit the shaft bending caused by the large unbalance of the iron core according to the quality management of the hardware mold and the operation of silicon steel sheet thickness. The laminated steel plates will be converted into accumulation. For example, the 12-slot rotor will be divided into three stacks, and each stack will rotate 120 degrees.
2, shaft pressing into the rotor core: shaft pressing machine generally adopts pneumatic or hydraulic press, because of the permeability of the production process, it is possible that the pressing force is too large and the shaft is bent. Check the shaft press-in force and give an alarm to avoid shaft bending if the press-in force is too high. When the pulling force of the press presses the shaft, whether the shaft is relatively limited and fixed to prevent verticality deviation after pressing the iron core.
3. Fan blade pressing into shaft: effective design scheme: fan blade pressing into shaft overalls to ensure deformation during pressing
