Diesel Generator Tech

  The function of diesel generator set coolant is to dissipate a large amount of heat generated during unit operation, in order to ensure the normal use of the unit. So how to use diesel generator set coolant? What details do you need to pay attention to? This article is briefly introduced by Guangxi Dingbo Power Equipment Manufacturing Co., Ltd., a professional generator manufacturer. 1. Choose clean soft water Soft water usually includes rainwater, snow water, and river water, which contain few minerals and are suitable for use in  diesel engines . The mineral content in well water, spring water, and tap water is high, and these minerals are prone to deposit on the radiator wall, water jacket, and water channel wall when heated, forming scale and rust, which reduces the heat dissipation ability of the generator set and easily leads to overheating of the engine. The added water must be clean, as impurities in the water can clog waterways and exacerbate the wear of components ...

The previous article has already shared with you the four major details that need to be paid attention to during the use of diesel generator coolant: selecting clean soft water, not starting without cooling water, not letting the generator set discharge water at high temperatures, and "boiling" to prevent burns. In this article, Dingbo Power Equipment will continue to share with you other details about the use of   diesel generator   coolant. 1. The water discharge is about to be completed, and the diesel engine will rotate several times in time and space When the cooling water stops flowing out, it indicates that the drainage work is about to be completed. The diesel engine starting motor should be used to idle the diesel generator set for a few revolutions, so that the remaining water inside and the water that is not easy to flow out can flow clean due to the vibration of the diesel engine. After the water is drained, the drain switch should be in an open position to preven...

The installation of the electrical system of diesel generator sets needs to consider factors such as the cable laying method, the selection of cable laying path, and the general requirements for cable laying. This article shares the installation methods for the electrical system of diesel generator sets with Dingbo Power Equipment. 1. Cable laying method for  diesel generator set There are several ways to lay cables, including direct burial, using cable trenches, and laying along walls. 2. Selection of cable laying path for diesel generator sets When selecting the cable laying path for the generator set, users should consider the following principles: (1) The shortest power path with the least number of turns; (2) Minimize damage to cables due to mechanical, chemical, and ground current factors as much as possible; (3) Good heat dissipation conditions; (4) Try to avoid crossing with other pipelines; (5) Areas that require excavation in the plan should be avoided. 3. General require...

The fuel pipeline of the diesel generator set should be made of carbon steel or stainless steel seamless steel pipes instead of galvanized pipes. The direction of the oil pipe should be as much as possible to avoid the influence of excessive fuel heat dissipation by the engine. Today, a professional   generator manufacturer , Dingbo Power, will introduce the installation method of oil pipes for generator sets. The fuel pipeline of the generator set not only has an inlet pipe, but also a return pipe. The diameter of the fuel inlet pipe depends on the inlet diameter of the fuel pump, which should be at least the same as the inner diameter of the intake duct; If the distance is too long, the diameter of the fuel pipe should be appropriately increased. When selecting oil pipes, attention should also be paid to the initial freezing point and freezing point of diesel. When the temperature of diesel approaches these two values, it will become viscous and the diameter of the pipeline shoul...

  The speed regulation methods of diesel generators include electric injection and electric regulation. Both belong to electronic speed regulation, and the difference lies in the control method of mechanical speed regulation. Below, the professional diesel generator manufacturer - Dingbo Power will introduce the difference in speed regulation control execution and fuel injection control between   diesel generator   electromechanical injection and electric governor. 1. Speed control execution method: The electric speed controller is a speed controller that is fed back by a speed sensor to the machine's speed signal. The speed controller converts the difference into a speed control signal by comparing the pre-set speed value to drive the actuator to control the oil supply rack or sliding sleeve to achieve speed control. The oil supply signal only relies on the speed signal, and the oil supply adjustment is achieved by the mechanical action of the actuator. The electronic fu...

IP21 generator, generally referring to land use; IP26 generator, generally used in ships; IP44 water-cooled generator, generally used in ships. So what is the classification and definition of   generator   protection level (first digit)? 1. No protection or specialized protection. 2. Protecting solids larger than 50mm can prevent solid foreign objects with a diameter greater than 50mm from entering the shell. It can prevent a large area of the human body (such as the hand) from accidentally or accidentally touching the charged or moving parts inside the shell, but it cannot prevent conscious access to these parts. 3. Protecting solids larger than 12mm can prevent solid foreign objects with a diameter greater than 12mm from entering the shell. It can prevent fingers from touching live or moving parts inside the shell. 4. Protection against solids larger than 2.5mm can prevent solid foreign objects with a diameter greater than 2.5mm from entering the shell. It can prevent tools,...

If the speed of the Cummins diesel generator set is unstable, the first thing to observe is whether there is any leakage at the interfaces of the fuel system. If there is no leakage, loosen the bleed screw of the fuel injection pump and press the hand pump to remove air from the low-pressure oil circuit. If there is no air inside the low-pressure oil circuit, the inlet filter screen of the fuel transfer pump should be removed for inspection. If the oil inlet filter screen of the fuel transfer pump is not blocked, the diesel filter or oil tank inlet pipe should be checked for blockage, air leakage, etc. If the unstable speed still occurs, the following checks and adjustments should be carried out in sequence based on actual usage: 1. Check if the connecting parts are loose, if the pipes are broken, and if the filters are not tightened, and correct them one by one; Check for wear, replace and adjust the transmission rod. 2. Reassemble and adjust the idle spring, readjust the speed limite...
