Diesel Generator Tech

As a common backup power supply equipment, diesel generators are widely used in various important places, such as hospitals, data centers, and commercial buildings. In practical use, operating a diesel generator at excessively low loads can negatively impact its performance and service life. What is the minimum load ratio of a diesel generator? Basic principles and load requirements of diesel generators A diesel generator produces electricity by a combination of a diesel engine with an electric generator (commonly known as an alternator). To maintain normal operation, it requires a certain load. Both excessively low and high loads can damage the generator set. The load ratio refers to the proportion of the generator’s output power relative to its rated capacity. For stable operation and extended lifespan, the load ratio of diesel generating sets should ideally be maintained between 60% and 80% of the rated power. Within this range, the power generators can operate efficiently, avoid ...

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. ...

In the petroleum and petrochemical industry, the stability and reliability of power supply are critical. Whether for offshore drilling platforms, refineries, chemical plants, or gas stations, the operation of these facilities depends on a dependable power supply. Therefore, selecting appropriate diesel generator sets is not only vital for enterprises’ daily operations but also crucial for production safety, environmental protection, and economic efficiency. Today, Dingbo Power will explore the key factors when selecting diesel generators in this industry. As a core sector of the energy industry, the petroleum and petrochemical field has diverse and complex power demands. For instance, drilling platforms require auxiliary generator sets to provide power, typically in the 300–500 kW range. Departments such as workover and well testing may need power generators with capacities between 20–300 kW, while LNG terminals and gas stations require emergency backup power to ensure uninterrupted s...

Recently, the Shanghai Municipal Government issued a significant notice, deciding to implement the National VI B emission standard ahead of schedule starting from July 1st this year. Although industry insiders had been prepared, this notice still attracted wide attention. It means that the strictest National VI B emission standard in history has truly arrived. The era mission of winning the "Blue Sky Defense War" has begun. The National VI B emission standard presents both opportunities and challenges for the engine industry. Many large engine manufacturers are sparing no effort to produce engines that are powerful, cost - effective, and can meet the National VI B emission standard.   Today, Dingbo Diesel Generator Manufacturer wants to recommend two super - series engines. Once launched, these engines became industry stars, winning the praise of 99% of industry insiders. They are the R and M series engines produced by Shangchai Power, an engine manufacturing enterprise wi...

Weichai is the earliest enterprise in China to develop and produce generator sets, with a production history of over 60 years. It mainly produces land - based and marine generator sets, including diesel - type and gas - type units. Weichai's M33 series engines include 6M33, 12M33, and 16M33 diesel engines. These are high - power high - speed diesel engines independently developed by Weichai based on the mature product platform of Baudouin's M26 series in France. The development of this series of models fills the gap in Weichai's high - speed diesel engines for power generation in the 500 - 1530kW power range, enabling effective competition with foreign brands.   The M33 series Weichai engines inherit and carry forward the advanced product development and design concepts of the French Baudouin M26. They are benchmarked against international advanced engines, effectively avoiding various design defects. The product development emphasizes high reliability and low emissions....
