Diesel Generator Tech

An engine-driven welding generator, also known as a welder generator, is a mobile integrated device combining a generator set and a welding machine. Powered by a gasoline or diesel engine, it is primarily used in scenarios without access to an external power grid, such as municipal engineering, field pipeline construction, power emergency repairs, and mining/industrial construction.   This equipment utilizes high-frequency inverter technology to share power generation and welding functions, significantly reducing size and improving efficiency. It features stable welding current and strong penetration. Its auxiliary power output can support electrical demands like lighting under 5kW.   Gasoline welding generators emphasize portability for short-duration tasks, while diesel welding generators are suited for prolonged continuous operation. Some models support dual-operator welding or gas-shielded welding functions, are compatible with electrodes from ...

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 ...

At present, in an environment where the public power grid cannot guarantee permanent stability in electricity consumption, more and more enterprises, units, and institutions are purchasing diesel generators for emergency needs. Regardless, power outages will have a certain impact on production, operation, and daily electricity consumption.   Diesel generator sets   are currently one of the most popular and reliable backup power sources, widely used in various industries and regions, becoming an indispensable part of equipment, whether it is commercial, industrial, hospital, school, high-rise buildings, military facilities, etc If you are a person who often finds it inconvenient due to power shortages, you would consider purchasing diesel generators to protect your business and economic interests. Now is the time to take action to avoid another power outage.   Nowadays, many people design a diesel generator set, which is only suitable for large-scale industrial application...

A diesel generator set is a power supply equipment that is powered by a diesel engine and drives an AC synchronous generator to generate electricity. In order to meet the higher requirements of modern society for diesel generator sets, what are the performance levels and working conditions of   diesel generator sets ? This article is shared by Dingbo Electric as follows. Four performance levels of diesel generator sets 1. G1 level performance: suitable for connected loads that only require specifying basic voltage and frequency parameters. Mainly used for general purposes, such as lighting and other simple electrical loads. 2. G2 level performance: suitable for loads with the same voltage characteristics as public power systems. When the load changes, temporary but allowable voltage and frequency deviations may occur. For example, lighting systems, fans, and water pumps. 3. G3 level performance: suitable for connecting devices with strict requirements for frequency, voltage, and wa...

The detachment of the gas valve in the Volvo generator set is a serious fault phenomenon, and its consequences are relatively serious. The main reasons for its occurrence are twofold. Next, Dingbo Power Generation Equipment will briefly introduce to you: On the one hand, it is caused by the detachment of the air valve card group. When the phenomenon is severe, it will cause the air valve top rod to bend and deform, increase the gap between the air valve rocker arm and the top rod, and cause obvious bridge jumping. The air valve lock clip will pop out, ultimately leading to detachment. On the other hand, due to damage to other components, the air valve may fall off. For example, the main function of the air valve lock clamp is to fix it. Once it breaks, it will cause the air valve to fall off, and the bridge conduit can also cause this situation. The bridge conduit's main function is to locate it. Once the conduit breaks, it will cause the bridge to malfunction and collide, causing ...

  Today, we will briefly introduce the content that pitting corrosion is an important factor affecting the service life and reliability of Volvo generators. Insufficient oil output from the oil pump: There are two types of oil pumps for  diesel generating sets : gear pump and rotor pump. Some gear pumps have a low roughness of the joint surface between the pump cover and the pump body, and the original design did not add a gasket. If a paper gasket is added during maintenance, it will increase the end clearance of the gear and instead reduce the pump's oil output. But there is a gasket at the interface between the pump and the cylinder block. If it is not installed, the pressure oil from the oil pump will leak outward, causing a decrease in oil pressure. Some rotor pumps have chamfers on one side of the outer rotor and no chamfers on the other side. If installed upside down, the oil output can be reduced by 40-60%. In addition, excessive radial and end face clearance of gears ...

  What should we do when we find that the diesel generator set engine is slowly stalling? Firstly, check whether there is oil in the fuel tank of the   diesel generator set   and whether the vent valve of the fuel tank cap is unobstructed. Qualified fuel will not contain impurities and moisture when leaving the factory, but will be mixed with dust, dirt, and moisture to some extent during transportation and storage. Loosen the bleed screw of the fuel injection pump, pump oil with a hand pump, and observe the oil flow at the bleed screw. If there is no oil flowing out, it means that the oil circuit is blocked, and it should be checked and eliminated section by section. If diesel is emitted in a spray column, it indicates that the oil circuit is unobstructed. If there are bubbles emerging from the vent screw, it indicates that air has entered the pipeline. It is necessary to check whether the joints of the oil pipe are tightened, whether there are cracks or abrasi...

What are the measures to prevent cylinder gasket burning of Volvo diesel generators? Firstly, improve the maintenance and assembly quality of Volvo diesel generators. Poor repair quality of Volvo diesel generators is the main factor causing cylinder gasket burning. When repairing   Volvo diesel generators   for this purpose, the following points should be taken into account: firstly, the cylinder sleeve should be correctly assembled. Before the cylinder sleeve is inserted into the cylinder, the external surface of the cylinder sleeve, the upper and lower parts of the cylinder block seat holes to the bearing shoulder should be thoroughly cleaned of dirt and rust, and the trial fitting work between the cylinder sleeve and the cylinder block seat holes should be done well. During trial assembly (without installing a water stop ring), the cylinder liner should rotate flexibly in the cylinder block seat hole without jamming, and there should be no obvious gap feeling during radial ...

The parts where cracks occur on Volvo diesel generator sets are often related to their structures. The parts where cracks occur on different types of Volvo diesel generator sets have certain regularity. Generally speaking, there are only three reasons for cracks in Volvo diesel generator sets. The cylinder block of Volvo diesel generator set has complex structure and uneven wall thickness. The rigidity of some weak parts of Volvo diesel generator set is low, and Volvo Diesel generator set is easy to crack. The stress concentration of Volvo diesel generator set occurs at the transition of machined parts, unprocessed parts and wall thickness. When these stresses are superimposed with the residual stress when the construction stops, Volvo diesel generator set is easy to crack. In cold winter, the cooling water in the water jacket of the  Volvo diesel generator set  freezes and cracks, or the hot water bursts in cold winter, because the Volvo diesel generator set does not have ant...

  Today, we will briefly introduce how to fill diesel fuel for Volvo generator sets. The diesel engine is the core component of Volvo generator set and the heart of the whole operation. If there is no oil, it should be refueled in time. But do you know the correct refuelling method? Is it true that diesel fuel will lead to fuel tank? Often these familiar details are the factors that lead to component damage, and even directly affect the service life of Volvo generator unit components and even the entire unit. Volvo generator sets  feel that the fuel supply advance angle should be earlier: some mobile power station operators often prefer to move forward when adjusting the fuel supply advance angle of diesel engines, and some even exceed the specified value by 2-3 degrees. They feel that if the fuel supply advance angle is adjusted forward, the engine will work vigorously. However, they do not know that the premature fuel supply advance angle is equally harmful to the work of th...

  Although the Volvo diesel generator injector is a small part, if it fails, the entire equipment has to be shut down. Therefore, it is necessary to maintain the Volvo diesel generator fuel injector. If the fuel injector is not cleaned for a long time, grease will be produced, which will block the fuel injection nozzle and cause poor fuel injection. First of all, when the technical workers assemble the injector, they must install the assembly standard to prevent the assembly from being in place. Be extra careful when installing the fuel injector heat shield, neither too loose nor too tight, too loose, there is a gap between the fuel injector and the heat shield, the heat insulation effect is greatly reduced, and it is easy to cause the fuel injector And the heat shield burns off. If it is too tight, the injector will feel oppressed. Under the combined action of the thermal alternating load and the high pressure load of fuel injection, the head of the injector will be broken, the ne...
