Diesel Generator Tech

This article continues to introduce the repair procedure for 700kw diesel generator components. Crankshaft and Flywheel Assembly The main damages to the crankshaft include: journal wear, cracks and fractures of the crankshaft, and ablation caused by bearing burnout. If the out - of - roundness of the crankshaft journal exceeds 0.05mm, the crankshaft journal needs to be ground. For a crankshaft with severe bearing burnout, since its metallographic structure has changed, it is generally not recommended to use it again. A crankshaft with cracks must be scrapped; otherwise, it may break. Warning: The installation of the crankshaft and flywheel assembly must be carried out personally by the engineering director, following the correct torque and correct steps. The main bearing cap screws must be re - checked.   Cylinder Head and Valve Train 1.Cylinder Head Cracks are likely to occur at the joint plane between the cylinder head and the cylinder block, the valve guide holes, the val...

Repairing a 700kW diesel generator follows certain procedures. How can you quickly and accurately locate the generator's faults? You need professional and systematic knowledge of generator repair. Today, the author will popularize relevant content for you. Cylinder Block 1.Damage to the Cylinder Block Common damages to the cylinder block include bearing burnout, deformation of the main bearing holes, cracks, breakage, corrosion of the water port, and wear of the mating surfaces. During visual inspection, there should be no cracks or damages. If any damage that causes water leakage, oil leakage, or air leakage is found, it must be repaired or replaced. Special attention should be paid to checking for cavitation and corrosion at the sealing ring area where the cylinder block contacts the cylinder liner. 2.Main Bearing Holes For cylinder blocks with bearing burnout, the diameter of the main bearing holes must be measured, and non - standard main bearing holes must be corrected. ...

 Diesel generator sets can be widely used in various types of enterprises in different industries such as communications, power, petroleum and petrochemical, civil aviation, expressways, ports, ships, national defense, nuclear industry, energy, radio and television, metallurgy, construction, and postal services. It is particularly important for users to have a good understanding of professional knowledge about generator sets. Just as the saying goes, "Know yourself and your enemy, and you can fight a hundred battles with no danger of defeat." Mastering certain professional knowledge about the 700kW Shangchai generator set can help solve problems efficiently and quickly when encountering faults later. Dingbo Power's Generator Knowledge Mini - Course is sharing knowledge about generator set paralleling today, hoping to help everyone solve their problems. What are the conditions for parallel operation of generator sets? The whole process of putting a generator set into par...
