China has a vast territory, and there are many high - altitude areas in the central and western regions, including Tibet, Qinghai, Yunnan, Guizhou, Sichuan and other places. In the remote areas of these provinces and autonomous regions, it is often difficult for the power supply to reach the load center. Therefore, diesel generator sets need to be purchased as the common power source. In the plateau area, due to the high altitude, the oxygen in the air is relatively thin. People living on the plain usually have altitude sickness when they go there, which is generally manifested as mild headache, insomnia, mild chest tightness, excessive excitement, etc. The working principle of a diesel generator set is to obtain energy through the combustion of diesel. So, will the plateau environment have an impact on the use of diesel generator sets?   Due to the low air pressure and thin air in the plateau area, the oxygen content in the diesel generator set is low, and the ambient temperatu...

Diesel engines of generator sets may develop various faults during operation due to diverse causes. If the root cause is not identified and addressed promptly and you allow the engine to continue operating with faults, it can lead to reduced power, increased fuel consumption, and even catastrophic failures. This article briefly introduces the causes of diesel engine failures and common methods for diagnosing them. Causes of diesel engine failures Diesel engine faults generally fall into two categories: 1. Gradual natural wear: Includes corrosion, fatigue wear, and abrasive wear. This is a normal process that can only be mitigated through proper maintenance and usage to extend the engine’s lifespan. 2. Sudden failures: Caused by improper operation or poor maintenance, such as insufficient oil/water levels, clogged fuel lines, water ingress, dirty filters, or incorrect fuel injection/valve timing. While fault causes vary, systematic analysis based on symptoms can simplify troubleshoo...

Diesel generator sets generate a large amount of heat during operation. For the units used in the engine room, the heat is even more difficult to dissipate. Once the diesel generator set operates in an environment with excessively high temperature, its load - carrying capacity will also decline. There are two cooling methods for diesel generators: air - cooling and water - cooling. When the air - cooling method is adopted, the maximum temperature of the diesel generator room should not exceed 35°C. If there is no condition to build vertical air intake and exhaust ducts in the diesel generator room or the area is insufficient, supply and exhaust fans need to be added to ensure the supply and discharge of air volume, which should be calculated according to the actual situation. When water - cooling is used in the diesel generator room, the air intake volume can be calculated at no less than 20 m³/(kW·h) of the rated power of the diesel engine.   Design of the Diesel Generator Set ...

 According to the specific conditions of the generator's electromechanical equipment and the construction conditions, different methods can be used to install the generator rotor. For most medium - and small - sized generators, the shaft - connecting method is used to install the rotor. As a special tool, the extension (short) shaft for rotor installation is generally supplied by the manufacturer along with the generator. The normal procedure for installing the rotor of a Mercedes - Benz generator set is as follows: 1.Place a 0.8 - 1.0 mm thick cardboard along the entire length of the lower half - arc inside the stator. Move it back and forth at any time during the entire process of rotor installation to check if the rotor collides with the stator. 2.Position 1: The rotor is equipped with a short shaft and a rear bearing seat. The wire rope is hung on the part of the rotor cylinder close to the center for balance, keeping the rotor horizontal. Align it with the center of the sta...

Diesel generator sets are indispensable power generation equipment in modern society. The performance of the diesel engine speed control system determines the overall electrical characteristics of the generator set, such as frequency response, voltage regulation, and load-bearing capacity. As one of the core components of diesel generators, the electronic governor plays a vital role in power regulation and maintaining stable operation. Below is an overview of the working principle, features, and applications of electronic governors for diesel gensets.   Working Principle The electronic governor primarily consists of a controller, actuator, and sensors. It achieves precise engine speed control by receiving and processing electrical signals. Sensors (typically using Hall elements or magnetic induction components) collect engine speed signals. The controller processes these signals, performs calculations, and outputs control commands to the actuator. The actuator then adjusts the f...

Different schools have different numbers of teachers and students, and different quantities and types of teaching equipment. There are many places that need electricity. For example, a university usually consumes more electricity than a high school, including the power used by training equipment, teaching equipment, and scientific research equipment in schools. However, there are a wide variety of brands and models of diesel generator sets on the market currently. Which type and brand are more suitable for schools? Normally, schools get their electricity from the municipal power supply. When the municipal power is rationed, cut off, or interrupted for other reasons, it is necessary to set up standby diesel generator sets to provide continuous power supply and ensure the normal study and life of teachers and students in schools. The types of diesel generator sets suitable for schools are mainly divided into the following categories: imported diesel generator sets, joint - venture diese...

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...
