Diesel Generator Tech

With the increasing demand for electricity, diesel generators play a vital role as a backup power supply in various industries. However, many users don’t fully realize the importance of choosing right generator cables. As a bridge between the generator and the electrical equipment, the quality and performance of cables are directly related to the safety and transmission efficiency of electric power. Using wrong cables can lead to several risks, such as equipment damage and fire hazards. In this article, we’ll explore what you need to consider when choosing cables for your diesel generator sets. Generator cable size Choosing a right cable size for your generator sets is important. The cross-sectional area of the cable should match the amps of the diesel generator, so that it can carry the current of the generator without overheating or damage. An undersize cable will fail to carry the current of the generator. An overloading cable in a power generator installation can cause overheatin...

This article continues to introduce the gas ring function and working principle of the piston ring in diesel generator sets. In order to improve the working conditions of the piston rings and ensure better fit between the piston rings and the cylinder, some piston rings use different cross-sections, and special attention should be paid during installation. The basic cross-sectional shape of an air ring is rectangular. Rectangular rings are easy to manufacture and widely used, but their break in performance is relatively poor and cannot meet the increasingly stringent requirements of engines. This ordinary compression ring can be installed freely in the gas ring groove. Some engines use a conical ring structure. The working surface of this ring is designed with a cone angle of 0.5 ° to 1.5 °, which reduces the contact surface between the working surface of the ring and the cylinder wall, allowing for faster wear in. The cone angle also has the function of scraping oil. But the wear of t...

Electricity supply becomes increasingly important now and diesel generator sets play an indispensable role in various industries as the main power source or a backup power supply. Diesel generators have become the first choice of many enterprises and individuals due to their reliability and excellent performance. However, many users don’t pay attention to the generator maintenance and service, leading to the reduced performance, frequent malfunctions and even premature failures of generator sets. So how to prolong the lifespan of your diesel generator while improving efficiency? Here are several tips for you. 1. Place your diesel generator in a suitable location It’s important to keep your generator in the right place. Diesel generator sets should be placed in a well-ventilated and dry area and be kept away from flammable and explosive materials. Additionally, they should be placed on a solid and level surface to reduce the vibration and noise generated during the operation of the uni...

The repair of the bearing shell of a diesel engine must be carried out after a detailed inspection and restoration of all faults in the cylinder block and crankshaft. Preparation work before repairing and scraping the bearing shell (1) Prepare various tools such as socket wrenches, scrapers, etc. (2) Prepare the cleaning oil and wiping cloth. (3) Prepare the adjusting shims (0.05-0.2mm thick copper shims) for the main bearing and connecting rod bearing. (4) Clean the crankshaft, connecting rod bearing seat, bearing cover, and bearing shell, and block the oil holes on the bearing seat. The purpose of blocking its oil hole is to prevent impurities from leaking into the oil hole on the bearing seat and blocking the lubricating oil passage when scraping the tile. Repair and maintenance of connecting rod bearings Repair method (1) Lift the crankshaft onto a dedicated bracket or stand it on the flywheel. (2) Clean the connecting rod journal and bearing. If there are roughness or s...

Diesel generator sets are designed to provide electricity during power outages or in places without connection to a power grid. They are renowned for their durability, high efficiency, reliability and longevity. As an important part of the power supply system, the stability and safety of diesel generators’ electrical system is directly related to the continuity and reliability of power transmission. In this article, we’ll share several tips on how to maintain the generator’s electrical system. The electrical system of diesel generator set serves as the bridge to connect with mechanical energy and electric energy, and it is the key to ensure the stable transmission of power. However, the electrical system may encounter various problems over time, such as aging, wear and tear and contamination, which will affect its performance and stability. Therefore, the maintenance of diesel generator’s electrical system is essential. The electrical system of diesel generator set is mainly composed...

The working principle of the cooling system of a diesel generator set is heat transfer. Heat always moves from hot objects to cold objects. There are three ways of heat transfer: conduction, convection, and radiation. Conduction refers to the heat transfer between two solid objects. For example, heat is transferred from the valve stem to the valve guide. Due to both objects being solid, heat is transferred from the hot air rod to the cold valve guide through conduction. For example, heat is transferred from the air duct to the cylinder head through conduction. Heat can be transferred through convection. Convection is the heat transfer that occurs through the circulation of heat in a liquid or gas. Through convection, the heat from the hot cylinder body is transferred to the coolant, and when the hot radiator components transfer heat to the surrounding cold air, convection also occurs. Radiation is a way of heat transfer. Radiation is the heat transfer that occurs by converting thermal...

Before purchasing a backup power generator, you need to consider a number of factors, such as your power requirements and fuel source. A right diesel standby generator can provide you with reliable electricity and bring you peace if mind during power outages. However, many people often make the following 5 common mistakes when buying a backup diesel generator. To make sure you buy a right generator for your home or business, you need to avoid these mistakes. Overestimate or underestimate power requirements It’s important to pick a correct size diesel standby generator that can provide the necessary amount of power to run all of the equipment without overloading the generator. If you overestimate or underestimate the power need and select a wrong sized diesel generator set, the generator may be damaged and your business operations may also be affected. Oversizing your generator can lead to inefficient operation and increased fuel consumption, while undersizing may result in power outa...
