Yinguang Group Lean Maintenance and Quality Improvement

Recently, Yinguang Group Juyin Co.
, Ltd.
has implemented an innovative technology project for the alignment of large compressor couplings on the TDI production line, which not only improves the alignment accuracy of the compressor, but also optimizes the maintenance standards and extends the service life
.

During the operation of the V3601 four-row symmetrical reciprocating compressor of the hydrogen compressor of the TDI production line, the internal sliding bearing has signs of wear.
As the wear area increases, the gap between the crankshaft and the sliding bearing becomes larger and larger, resulting in an increase in the frequency of failures , The service life of the compressor is shortened
.

In response to the existing problems, Juyin Company communicated with the manufacturer’s technicians and repeatedly studied the equipment manuals and proposed that a jack can be used to forcibly support the crankshaft on the side of the motor during installation, and then the clearance between the bearing and the crankshaft can be adjusted by fine-tuning.

This technological innovation has been promoted to other large-scale compressor maintenance and incorporated into the "Equipment Inspection and Maintenance Regulations", providing technical support for future inspection and maintenance work
