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 ...

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...

This article continues to introduce the calculation method of impulse current for parallel operation of diesel generators. The expression of the transient inrush current during the no - load connection of a doubly - fed induction generator is derived. The influence of the voltage amplitude difference and the phase difference on the inrush current is analyzed, and corresponding measures to suppress the inrush current are proposed. When a three - phase synchronous generator operates symmetrically, the effect of a single - phase can be equivalently considered. Through the finite - element modeling of a single - phase generator, it is verified that the frequency difference has little influence on the inrush current. The closing operation for paralleling does not select the moment when the frequency between the generator and the system is the same. A slight frequency difference makes it easier for the main generator to pull the generator to be paralleled into synchronization. Therefore, the...

 In today's electrified era, power generation equipment is widely used. The fluctuation of the load leads to changes in the number of operating generators in the power system. The parallel operation of diesel generators (including grid - connected operation of generators) is a frequent and important operation. The parallel operation of generators has numerous application fields, such as ships, mines, and power plants, and plays a significant supplementary role in the national production and people's lives. As the single - unit capacity of synchronous generators continues to increase, when the two - phase circuits are connected at the moment of paralleling, appropriate paralleling conditions can enable a smooth transition from the original two stable operating states to one stable operating state. Improper operation will generate a harmful inrush current, which may cause electrical damage to the windings of the generator set and even produce a large electromagnetic torque, resu...

In various modern application scenarios, diesel generator sets serve as critical power backup equipment, and their stable operation is essential for maintaining the normal production and daily life. However, diesel generators may encounter various faults during operation. Knowing how to quickly identify and resolve these issues is key to ensuring efficient and reliable performance. Today, Dingbo Power will share some practical maintenance tips to help users better identify and resolve a few common diesel genset faults.   Before discussing maintenance techniques, it is essential to understand the basic structure and working principle of a diesel generator set. A diesel generator set mainly consists of a diesel engine, an alternator, a control system, and auxiliary equipment. The diesel engine generates power by burning diesel, which drives the alternator to rotate, converting mechanical energy into electrical energy. The control system monitors the operational status of ...

Globally, the situation of environmental pollution remains grim. Problems such as soil pollution, smog, black and odorous urban river water, garbage - surrounded cities, plastic waste, and rural environmental pollution are prominent. The task of pollution control is arduous. The call for the rapid, continuous, and healthy development of the environmental protection industry and the fight against pollution are crucial tasks for humanity. However, ignorance and greed have left terrible consequences. All these remind us that environmental protection is extremely urgent! The well - known environmental pollution incidents around the world have sounded the alarm for us. For example, in the London Smog Incident in the UK, many people felt discomfort such as chest tightness and suffocation. According to official UK statistics, more than 5,000 people died during the 5 - day period of the heavy fog, and over 8,000 people died in the two months after the fog dissipated. How terrifying it is! Co...

With the increasing power demand and rising stability requirements, generator sets, as critical backup power equipment, make their manual starting function particularly important. It is not only the cornerstone for ensuring continuous power supply to critical loads but also serves as the direct means for operators to restore power when automation systems encounter difficulties. Below are the safety guideline for manual starting and stopping of generator sets. I. Necessary preparations before manual starting generator set 1. Safety check and system status confirmation First, perform a safety check. Ensure there are no flammable materials around the generator set, ventilation is adequate, and the exhaust pipeline is unobstructed. Carefully inspect the genset's exterior for any damage and check the control panel for any illuminated alarm indicators. Meanwhile, confirm that safety equipment such as the emergency stop button and protective covers are in proper working condition. Next, c...

As a backup or main power source, the stability and reliability of diesel generator sets are directly crucial to the proper operation of electrical equipment. However, long-term idling operation (i.e., the genset running at low speed for extended periods under no load or low load conditions) can cause significant damage to its performance, lifespan, and operational efficiency. This mode of operation not only contradicts the design intent of diesel engines but may also trigger a series of chain reactions leading to faults, increasing maintenance costs and the risk of downtime. Potential risks of long-time idling of diesel generators   1. Thermal stress damage: Component overheating leading to cracks or seizure   Cooling system failure After the diesel generator set is shut down, the circulation of cooling water stops immediately, and the heat dissipation capacity drops sharply. At this point, heated components such as the cylinder head, cylinder liner, and...
