Repair of reciprocating compressor crankshaft, diameter 350mm, length 7m, weight 7~8 tons
Crankshaft repair? How do you want to fix it? Is the crankshaft strained or worn? Previously, our crankshafts were generally repaired based on the minimum wear dimension; after such repairs, the manufacturer would have to produce corresponding thicker bearing shells for use with them.
For wear repair, it is best to restore it to its original dimensions after spraying
You can ask the person in charge of the lathe to take a look and see if it can be repaired. Generally, the worn areas are welded back together, and then the part is pulled to one side on the lathe; of course, the material has to be the same, haha
It is recommended to send it to a manufacturer capable of producing reciprocating compressors, as the repair of the worn parts requires machining on a crankshaft lathe; companies such as Shengyu and Dachuan are good options!
There are professionals in Yantai, Shandong who specialize in grinding crankshafts. You can also turn to Jiangyan Huayu to have aluminum alloy bearings fabricated; just provide the basic dimensions, and the bearings can be produced quickly
Thank you. Could you please provide your contact information?
Laser cladding technology is already a mature technology that has been in use for many years. The ones with the most cooperation are: Yueyang Mainland
The big bearing of a reciprocating machine burned out, so the crankshaft was taken to Guangzhou for processing of the journal area, which cost 2 million yuan
Recommended manufacturer: Shenyang Yuanda Compressor Factory； Shenyang Blower Factory
Let me give you a summary of the crankshaft repair manufacturers: Shenyang Steam Turbine Group, Shenyang Yuanda (whose owner used to work at Shenyang Steam Turbine Group before leaving), and Sichuan Jianyang Dachuan Compressors. All three of these companies are capable of repairing the crankshaft in question.
