Common Issues in Generator Maintenance Practices 1

In the production and operation of enterprises, generator maintenance is a crucial part to ensure the normal power supply and safe operation of the unit. There are many technical problems in repair and maintenance. If not handled properly, it will lead to low quality of mechanical equipment repair and maintenance, poor equipment reliability, and even serious equipment accidents. The problems existing in equipment repair methods are as follows:

1. The phenomenon of blindly dismantling equipment without correctly judging and analyzing faults is common.

When a mechanical failure occurs, it is necessary to use testing equipment for detection; if there is no testing equipment, traditional fault judgment methods and means such as "asking, looking, checking, and testing" can be used, combined with the structure and working principle of the equipment, to confirm the most likely location of the fault. Some maintenance personnel, due to unclear understanding of the mechanical structure and principle of the equipment, do not carefully analyze the cause of the fault, cannot accurately judge the fault location, and blindly dismantle the equipment based on the "approximate, almost" thinking. As a result, not only the original fault is not eliminated, but also new problems arise due to poor maintenance skills and technology.

2. There are quite a few cases of not paying attention to checking the fit clearance of parts.

In common diesel generator maintenance, the fit clearance between piston and cylinder liner, the "three clearances" of piston rings, piston top clearance, valve clearance, plunger clearance, brake shoe clearance, meshing clearance of driving and driven gears, axial and radial clearance of bearings, fit clearance between valve stem and valve guide, etc., all have strict requirements for various models, which must be measured during maintenance, and parts that do not meet the clearance requirements should be adjusted or replaced. In actual maintenance work, there are quite a few cases of blindly installing parts without measuring the fit clearance, leading to early wear or ablation of bearings, diesel engine burning oil, difficulty in starting or detonation, piston ring breakage, mechanical impact, oil leakage, air leakage and other faults. Sometimes, even serious mechanical damage accidents may occur due to improper fit clearance of parts.
