Diesel generator set maintenance: generator common parts repair method
July 07, 2022
Any mechanical equipment used for a long time can not avoid maintenance, including diesel generator sets, according to the scope of maintenance operations to divide, diesel generator set maintenance can be divided into: unit overhaul, assembly overhaul, diesel generator set minor repair and parts repair four categories.
Any machinery and equipment used for a long time can not avoid repair, including diesel generator sets, according to the scope of maintenance operations to divide, diesel generator set maintenance can be divided into: unit overhaul, assembly overhaul, diesel generator set repair and parts repair four categories.
1, diesel generator set overhaul: refers to the diesel generator set in operation for a certain period of time, after testing and diagnosis and technical identification, most of the assembly has reached the limit of use, so that a comprehensive restoration of the unit repair.
2, assembly overhaul: in order to restore the technical condition of an assembly, repair or replacement of any parts of the assembly (including the basic parts) repair operation is called assembly overhaul.
3, diesel generator set minor repair: according to the need, repair or replacement of individual parts of the unit repair operation is called diesel generator set minor repair.
4, parts repair: the parts that can not continue to use due to wear, deformation, damage, the use of appropriate processing methods to repair to restore its performance is called parts repair, parts repair should be consistent with the principle of economy.
In the usual unit failure, in fact, the need to do the most is to repair parts of this piece, the following top Bo power for diesel generator set parts repair methods for you to introduce a few common methods:.
There are many ways to repair diesel generator set parts, according to the characteristics of parts defects and repair costing to choose the appropriate repair method. Common parts repair methods are: mechanical processing repair method, pressure processing repair method, welding repair method and bonding repair method.
1, machining repair method: through mechanical processing methods to wear parts to restore the correct geometry and with the characteristics of the repair method is called machining repair method, commonly used to repair the size of the method and set repair method.
Repair size method is to match the worn parts according to the specified repair size to increase or reduce, and then match with another part with the same repair size to restore the matching nature of the repair method.
Set repair method is the parts of the wear parts for mechanical processing after shaping, and then according to the interference with a metal set to restore the basic size of the parts repair method.
2, pressure processing repair method: refers to the external force applied to the parts, the use of plastic deformation of the material to restore the size and shape of the damaged parts of the repair method.
3, welding repair method: the use of electric arc or gas combustion generated by the heat of the parts damage parts local and welding melted and fused to fill the parts wear parts or connect the broken parts repair method.
4, bonding repair method: the use of adhesive adhesion or connection of broken parts repair method.
Diesel generator sets need repair inevitably, in this top Bo power warmly reminded: regular diesel generator set sales will have after-sales warranty period, if your unit failure during this period need repair, please be sure to contact the generator manufacturer door-to-door repair, do not disassemble repair, so as not to be professional enough to cause greater damage to the unit, resulting in unnecessary economic losses.
Diesel generator manufacturers take you to understand what are the reasons that affect the power failure?
