Diesel Generator Tech

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 ...

If a diesel generator set is connected to an automated control cabinet, the overall unit becomes an automated diesel generator set. Automated diesel generator sets have many benefits. It can achieve fully automatic switching between two power sources, including mains and mains, mains and power generation, or between power generation, to ensure the normal power consumption requirements of users. What are the installation steps for the control box of  Yuchai diesel generator set ? Diesel generator manufacturer Dingbo Electric provides a brief introduction, hoping to be helpful to you. After the diesel generator set is installed directly by the manufacturer, it is shipped to the customer's place of use, and the operation and management personnel only need to understand it.   For power systems with strict requirements for power interruption time in shopping malls, hotels, and factories, a mains/generator automatic switching system should be used. This system can automatically swit...

What is the compression ratio of a diesel engine? Regardless of whether the equipment is equipped with a gasoline or diesel engine, maintaining a stable and appropriate compression ratio is essential to ensure smooth and stable operation of the diesel engine. The compression ratio of a general diesel engine is immutable, as the combustion chamber volume and cylinder working volume are fixed parameters that have been determined in the design. So what will be the impact of a decrease in compression ratio for diesel generators? The compression ratio is the ratio of the total cylinder volume of a diesel generator set to the combustion chamber volume. Its variation not only affects the power and economy of the generator set, but also affects its starting performance. In the design, each diesel generator set is specified with a compression ratio, but in use, due to various related factors, its compression ratio often decreases.  1.The position of the piston at the end of compression is l...

Thirdly, do not extend the s...

This article continues to introduce four parallel solutions for parallel controllers of diesel generator sets. 3. Manual parallel connection with load   1) After manual parallel connection, conduct a load test to observe whether the active and reactive power distribution of each unit is uniform;   2) After manual parallel connection, conduct a soft loading test to observe whether there is significant overshoot or power oscillation during the loading process. If there is, adjust the load slope appropriately:   3) After manual parallel loading, conduct a soft unloading test; Observe whether the unloading of the  generator set  reaches the minimum load percentage set value before opening the circuit breaker;   4) After manual parallel connection, perform load surge and unload tests to observe whether there is power oscillation phenomenon in the unit.   4. Fully automatic parallel connection   When the controller is in automatic mode and the switch in...

When the water temperature of the diesel generator set engine is high, in order to ensure the normal and efficient operation of the diesel generator set within the normal working temperature range, the water pump repeatedly circulates water to reduce the temperature of the engine. The water tank is composed of hollow copper pipes. High temperature water enters the water tank, passes through air cooling, and circulates to the engine cylinder wall to protect the engine. If the water temperature is too low in winter, the water circulation will be stopped to avoid the engine temperature of the diesel generator set being too low. If the radiator is not used properly, it can cause damage to the diesel engine and generator, and in severe cases, it can even lead to the scrapping of the diesel engine. Therefore, users must learn to use the radiator of the diesel generator set correctly. The cooling water tank consists of an upper water tank (chamber), a cooling core, a lower water tank (chamber...

The "three filters" of a diesel generator refer to the air filter, fuel filter, and oil filter. In the maintenance of a diesel generator set, the maintenance of the three filters is very important. The quality of their work directly affects the performance and service life of the diesel generator set. Currently, Dingbo Power has found that some users do not properly maintain the "three filters", resulting in frequent unit failures and premature entry into the maintenance period. It is worth noting that if the "three filters" of a   diesel generator   leak oil or crack due to manufacturing reasons, they can be repaired normally, but damage caused by improper maintenance is not covered by the warranty. Below, Dingbo Electric will introduce the correct maintenance techniques for the "three filters". 1、 Oil filter   Oil filters can be divided into three types: centrifugal oil filters, paper oil filters, and metal slotted filters.   1. Key maintenance...

  Diesel is the main fuel for diesel generator sets. Due to its low ignition point, the ignition form of diesel engines is compression ignition, which not only does not have an ignition system, but the structure of the fuel supply system is also very simple, making it more reliable than many gasoline engines. Therefore, it is widely used in various industries as an emergency backup power source. However, diesel is also an extremely flammable and explosive substance. Therefore,   diesel generator set   users must know the following knowledge about diesel! 1. Under what circumstances will diesel explode?   When the concentration of diesel vapor reaches the explosive limit (concentration of 0.6% -8.0%), it will explode if exposed to open flames or static electricity, which is related to the air pressure, temperature, and atmospheric humidity at that time. Dingbo Electric recommends that the fuel tank should not be filled too full. Oil tank overflow is a very dangerous t...

The starting circuit of the diesel generator has poor contact. Although various instruments are normal, the diesel generator cannot start. Here are some examples: Fault phenomenon: A Deutz F2L513 air-cooled  diesel generator  was originally starting normally, but after a system maintenance work, the diesel engine could not start. Pressing the start switch, the starter basically did not start. Fault diagnosis: It was initially suspected that the battery was out of charge. Due to on-site operations, there was no professional charger available, so power was taken from another device using a grounding method. The power of this device is also a Fl2 port 13 air-cooled diesel engine, which is starting and charging. However, after connecting the wires, the diesel generator still cannot start, and after turning on the start switch, the starter still does not turn. At this point, the operator of the equipment believes that there is a problem with the maintenance personnel's maintenance,...

The requirements for the valve distribution mechanism of diesel generators are that the structural parameters and form are conducive to reducing the intake and exhaust resistance, and the opening time and duration of the intake and exhaust valves are relatively appropriate, so that the intake and exhaust are as sufficient as possible to obtain larger power torque and emission performance. There are three main structural forms of transmission for the valve distribution mechanism of  diesel generators  (gear transmission, chain transmission, and synchronous belt transmission). A brief introduction is as follows: Gear drive 1. Suitable for center and bottom mounted camshafts. 2. The timing gear is a cylindrical helical gear tooth. 3. The material of the crankshaft timing gear is medium carbon steel, which can be directly machined on the crankshaft or embedded in a sleeve. 4. The camshaft timing gears are generally made of cast iron, but there are also rubber wood ones. 5. Gear tr...

Do you know the impact of not cleaning the air filter or replacing the filter element in a timely manner on diesel generators? The air filter is an important component of the diesel engine supply system, which can purify the air entering the trachea. If the air filter is not maintained in a timely manner, it can cause early wear and tear on cylinder liners, piston rings, intake and exhaust valves and other parts, resulting in a decrease in engine power and even shortening the service life of diesel engines. Experiments have shown that   diesel generators   without air filters have an 8-fold increase in cylinder wear, a 9-fold increase in piston ring wear, and increased wear on other components. If the air filter is not maintained in a timely manner or with poor maintenance quality, the effectiveness of the filter will significantly decrease. Some operators, in order to save fuel, do not install an air filter, or do not replace it in a timely manner when the filter is damaged, ...

How should we diagnose any abnormalities or malfunctions when using diesel generator sets? In fact, many times customers can diagnose through some simple methods. This article will introduce Dingbo   Power Generation   Equipment one by one for your reference. 1. Listening method: Use a stethoscope or use a metal rod to listen to the sound of each cylinder exploding near the fuel injector body. The normal sound is similar to the sound of metal tapping "dangdang". If there is only a continuous and non crisp sound of 'ho ho', then the fuel supply to the cylinder is too low or it has not caught fire in a timely manner. If the impact is large, it indicates that the fuel supply of the cylinder is too large or the fuel injection time is too early. 2. Color observation method: The diesel generator set is working normally, and the exhaust gas discharged is light gray with a slightly darker load. If black gas is discharged, it indicates incomplete combustion of combustible gas....
