Taboos When Starting Diesel Generator Sets

Sep. 14, 2023

What are the taboos when starting a diesel generator set that you know? Firstly, avoid not supplying oil according to regulations, do not add cooling water to the water tank after starting, and do not pull the engine to start. If the diesel generator set is pulled down to start when the cold engine oil is viscous, it will exacerbate the wear and tear between the moving parts, thereby reducing the service life of the diesel generator set. Avoid changing lubricating oil and fuel on schedule. The temperature in winter and summer is different, and the oil used is also different. In high temperature areas in summer, if lubricating oils with good high-temperature resistance indicators (such as 40, 50, 60, etc.) are not used, the antioxidant stability of the lubricating oil will deteriorate, exacerbating its thermal decomposition, oxidation, and polymerization, and it is easy to deteriorate.

The viscosity of lubricating oil will decrease with the increase of temperature, which can easily cause excessive consumption of lubricating oil; In winter, if low viscosity lubricating oil and low solidification diesel are not replaced in a timely manner, the internal resistance of the diesel engine will be large, making it difficult to start and accelerating the wear of various moving parts. Secondly, avoid using open flames for baking. To prevent a fire, use gentle or coal flames. The oil pan of the diesel generator set must be baked at a certain distance (30cm away), and the oil shaft must be slowly rotated to evenly heat the oil and lubricate all parts. If a fire is ignited at the intake pipe of a diesel generator set, the ash and hard debris generated by material combustion will be sucked into the cylinder, causing the intake and exhaust valves to close loosely and accelerating cylinder wear. The best way is to install a water jacket heater on the diesel generator set to maintain the temperature of the water tank and cylinder body at all times, ensuring that the diesel generator set can be started at any time.


Finally, it is important to avoid directly adding engine oil to the cylinder. Adding engine oil to the cylinder can serve as a seal, boost pressure, and increase temperature, making it easier for the diesel generator set to start cold. However, the engine oil cannot be completely burned, which can easily cause carbon deposition, weaken the elasticity of the piston rings, and decrease the sealing performance of the cylinder. In addition, it will accelerate the wear of the cylinder liner, leading to a decrease in the power of the diesel generator set, making it more difficult to start, so oil cannot be directly added to the cylinder.
