Reasons for Power Drop of Mine Diesel Generator Sets

Feb. 10, 2022

For the diesel generator set for mining, the diesel engine as the power part is a commonly used power supply equipment. If there is loss during the operation of the diesel generator set, if it is serious, the power of the machine will drop or be abnormally damaged. When the power of the diesel generator set decreases or decreases, it may be that the following problems occur during the operation:

1. If the mining diesel generator set is running and used for a period of time, the power will drop, which is normal. During the operation of the unit, under the condition of high-speed vibration, the parts will inevitably wear due to friction, such as between the cylinder liner and the piston, between the crankshaft and the bearing, etc. Even if these parts are lubricated, the machine will have a certain degree of "natural wear" after long-term use, which will affect the power.


2. The power of the diesel generator set has a certain relationship with the operating environment, such as the amount of air (mainly oxygen content). The most typical example is the power loss in high altitude areas. The reason is that the temperature is low, the air is thin, etc. The amount of diesel that can be burned is reduced, which affects the power of the machine; in addition, in some areas with high humidity, the power may be reduced.


3. Defects in machine maintenance will also reduce the power of the machine. Common maintenance problems include: the oil filter element is blocked; the air filter is too dirty, resulting in insufficient air intake; the fuel filter device is too dirty and the fuel injection volume is insufficient; the ignition time is not Correct; insufficient oil intake to the machine; poor atomization of the fuel injector; blocked piston rings; loose valve closure, etc. When the power of the machine decreases, in addition to the above factors of long-term use and operating environment, the user should consider whether the machine has insufficient inspection and maintenance work. In order to ensure the most efficient operation of the machine, inspection, cleaning, replacement of parts, and maintenance should be done in a timely manner.


Starlight Power Generation Equipment reminds you: the operation of mining diesel generator sets must be carried out in accordance with the relevant instructions for use, and maintenance work should be done regularly. Even the best quality machinery, or the most wear-resistant parts in time, will not have a long service life if it is improperly operated or lacks maintenance. I hope this article is helpful for you to understand the use of diesel generator sets.
