Due to the low external environment temperature of the diesel generator set, when the water temperature drops after 15 minutes of shutdown, the cooling water should be discharged, but not immediately. Otherwise, due to the large temperature difference between the body and the external environment, some components of the   diesel generator set engine   will deform, which will affect the performance of the diesel generator set engine (such as cylinder head deformation). When draining water, it is not advisable to turn on the drain switch to ensure that everything is in order. It is also important to observe the specific condition of the water flow to see if it is smooth and if there are any signs of water flow decreasing or slowing down. If these situations occur, it indicates that the cooling water contains impurities that hinder the normal flow of water. At this time, it is advisable to remove the drain switch and allow the cooling water to flow directly out of the body. If the water f

Today, we will briefly introduce the common faults of regulators in   Volvo diesel generator sets . If you have any further information, please feel free to visit our Dingbo website. Next, we will introduce relevant materials to you. The repair method for contact burning is to use a fine file, platinum sand strip, and "00" sandpaper for grinding when the contact burning is not severe. When using a filing knife for grinding, the filing knife should be flat to avoid filing the contact points diagonally. When applying sand strips or sandpaper for grinding, it should be inserted into the fusion surface of the two contacts, and a slight amount of working pressure should be applied to the moving contacts. Then, the sand strips or sandpaper should be pulled out repeatedly, and the contacts can be ground off. After grinding, the contact points should be pulled and ground using "00" sandpaper in the above way, and then wiped clean with a clean strip of paper. If the contact

The fuel injection pump of a diesel generator set is an important component of the diesel engine fuel supply system, which increases oil pressure, controls fuel injection time and quantity. Its working condition directly affects the power, economy, and reliability of the   diesel engine . The fuel injection pump is driven by the engine crankshaft gear to rotate the camshaft to complete the fuel injection function. The fuel injection pump is usually equipped with a speed controller to ensure the low-speed operation of the diesel engine and limit the maximum speed, ensuring a certain relationship between the injection amount and the speed. There are five measures to prevent internal leakage in the fuel injection pump of diesel generator sets: (1) Ensure the cleanliness of diesel fuel. The characteristics of the diesel engine fuel supply system and the formation method of the combustible mixture determine that the filtering requirements for diesel in diesel generators are much higher than

The high efficiency and energy-saving of diesel generators have made the diesel engine of automobiles increasingly apparent. The electronic fuel injection system is currently the main development feature of   diesel engines   and a powerful means to meet stricter emission regulations. With the implementation of Euro III and IV emission standards, it is required to increase the pump end pressure of the distribution pump to over 100MPa. The original mechanical structure of the distribution pump can no longer meet the above requirements, and the mechanical structure of the distribution pump is facing new changes. A new type of VP44 internal cam electronic control distribution pump has been developed on the market. It adopts an internal cam, radial opposed plunger oil supply, and a distribution rotor rotating distribution structure. Using high-speed solenoid valves to directly control the high-pressure fuel supply. The pump end pressure is 100MPa, and by utilizing the pressure wave effect

The formation of fuel mixture in diesel generator sets is carried out in the combustion chamber of the diesel engine. The diesel generator is high-pressure injected into the combustion chamber, and after compression ignition, it undergoes a diffusion combustion method of simultaneous injection and combustion. This working mode determines that the mixture of diesel and air is uneven, inevitably leading to local hypoxia or oxygen enrichment. The surplus air is prone to producing exhaust emissions such as CO2, CO, HC (hydrocarbons), PM (particulate matter), etc. under high temperature conditions. In this article, let's learn about the types of exhaust emissions from   diesel generators   together. 1. C02 (carbon dioxide) is produced by burning substances containing carbon elements. Since the beginning of the 21st century, with the significant consumption of fossil fuels such as oil and the extensive deforestation of tropical rainforests as absorption sources, the CO2 content in the at
