Analyze why Baudouin diesel generator sets are prone to failure?
1. Properties of materials and oil
In the design and manufacturing process, materials should be correctly selected according to the working nature and characteristics of the generator set parts. Improper selection of materials The main reasons for the wear, rotting, deformation, fatigue damage, cracking and aging of parts are the non-compliance of materials and the selection of inappropriate substitutes.
A. The structural characteristics of the machine parts
Each system component of an internal combustion engine has its own characteristics in terms of structure. At work, external factors often act through these characteristics, causing the related parts to fail.
Due to the structural characteristics of the engine water jacket, under the action of high temperature, the cooling water is likely to form scale on the outer wall of the cylinder liner, which affects the cooling effect of the cylinder liner.
B, the working characteristics of accessories
Wear between parts that are in direct contact and have relative motion due to friction.
The piston ring of the internal combustion engine is in direct contact with the cylinder. During the working process, the piston ring performs a high-speed reciprocating linear motion in the cylinder, which causes the cylinder to wear.
2. Improper use
The user does not use the machine in accordance with the operating rules, such as often running at low speed, rapidly increasing the load without warming up the machine, and low oil pressure, which will accelerate the wear of the machine parts.
Excessive working hours, excessive load changes, and long-term overload operation will also cause premature failure of parts.
A. Poor maintenance
When maintaining the machine, the work was not completed in strict accordance with the specified technical requirements, or the wrong operation method was adopted, causing human failure, etc. In the usual maintenance, it is necessary to change the oil in time, and regularly clean the air filter and the scale of the water tank. Routine maintenance of the machine and 1 2 3 as required
level maintenance.
B, the repair quality is not high
In the repair process, if the processing is improper and the repair technical requirements are not met, such as improper fitting clearance of each part, insufficient surface roughness, and unclean assembly cleaning, the unit will fail during use.
The mutual positional accuracy between the parts in the assembly process is also very important. If the requirements are not met, additional stress will be caused, resulting in unpredictable consequences and accelerated mechanical failure.
In the process of using the Baudouin diesel generator set, it is necessary to establish a reasonable maintenance system, and strictly implement the technical maintenance and operating procedures of the generator set, so as to ensure the reliable operation of the generator set and increase its service life.
