Abstract

The invention discloses a high-voltage diesel generating set assembly alignment debugging process. The process can complete surface alignment and hole alignment of a generator and an engine of a high-voltage diesel generating set so as to reduce the vibration of the set.

Description

technical field [0001] The invention relates to a debugging process during assembly and matching of a high-voltage diesel generator. Background technique [0002] When the high-voltage diesel generator set was assembled and used, some customers reported that the vibration of the unit was too large, causing the whole unit to move about 60mm toward the water tank, which seriously affected the use. Improper alignment will cause excessive vibration, shorten the life of bearings and couplings on engines and generators, and often require re-alignment. Good alignment includes proper shims, correct tightening torques for mounting bolts, highly accurate dial indicators, and allowances for bearing play, thermal expansion, and other engine characteristics. [0003] Before any measurement or calibration is made, all surfaces to be measured and mating surfaces must be completely clean of grease, paint, oxides or rust and dirt - all of which can cause inaccurate measurements. [0004] D...
