Why generator manufacturers do not recommend you to run diesel generator sets overload?

Diesel generator set operation process, the general power will be floating up and down, standby power is diesel generator set can reach, but not long-term use of power, when encountering some special circumstances, especially the purchase of diesel generator set power can not reach the requirements, diesel generator set will enter overload operation.

Diesel generator set running process, the general power will be floating up and down, standby power is diesel generator set can reach, but not long-term use of power, when encountering some special circumstances, especially the purchase of diesel generator set power can not meet the requirements, the diesel generator set will enter overload operation. Overload operation will cause some damage to the diesel generator set, so we must do some understanding of the diesel generator set power when we buy a diesel generator set.

 

Diesel generator sets generally have a primary power and standby power. The main power of the diesel generator set is also known as continuous power or long line power, refers to the diesel generator set can be used continuously within 24 hours of the maximum power; and in a certain period of time, the standard is 1 hour within every 12 hours can be based on continuous power overload 10%, this time the unit power is what we usually call the maximum power, that is, standby power. In China, the main power is commonly used to identify the diesel generator set, while in the international are used to identify the standby power, also known as the maximum power to diesel generator set.

 

For example, if you buy the main 400kw unit, then you have 1 hour within 12 hours can run to 440kw, if you buy a standby 400kw unit, if you do not overload the usual 400kw, in fact, the unit has been open in the overload state (because the actual rated power of the unit is only 360KW), which is very detrimental to the unit, will shorten the life of the unit and cause. This will shorten the life of the unit and cause a higher failure rate. This is why generator manufacturers do not recommend you to run diesel generator sets overload, in addition, overload operation will cause the following hazards.

 

(1) when the diesel generator set into overload operation, with four protection diesel generator set will protect themselves and stop the power supply, so that the diesel generator set is not very harmful.

 

(2) diesel generator sets operating in a high-load environment, will make the diesel generator set internal zero flower rapid aging, seriously affect the use of diesel generator sets. And it will generate high temperature and make the parts heat deformation. When beyond the unit's capacity, the diesel engine crankshaft fracture, the diesel engine scrapped.

 

In summary, we recommend that when you purchase a diesel generator set must choose the correct power diesel generator set according to their own use, remember to buy large not small, and at the same time to do a good job of maintenance work on a regular basis, in order to increase the service life of diesel generator sets.
