How to Choose Diesel Generator Sets

As a complex large-scale power generation equipment - diesel generator set, we need to consider many factors when purchasing, because the principle of diesel generator set is relatively complex. In addition to the purchase price, we also need to understand the relevant parameters of diesel generator sets. For example, what power, brand and configuration of generator set should we choose? Cummins generator manufacturer Dingbo Power will discuss with you.

1.How to choose the power of the generator set

Some machines have a large starting current, generally 2-3 times, which requires that the proportioned generator set should also be more than 2 times or even 3 times. For example, a 12kw crusher needs to be equipped with a generator set of 2-3 times, so we should choose a 30kw generator set. Of course, not all the sum of machine loads is 2-3 times. If there are technicians operating to start the machines one by one, the main consideration is the load of the first three machines. If simultaneous start is required, it is better to have more than 2 times.

As a manufacturer selling generator sets, Dingbo Power does not recommend this proportion to purchase generator sets based on corresponding industry experience, because the cost performance is not high. The recommended proportion is to start separately according to specific conditions, and then calculate the required power of the generator set.

For example: The total load of equipment in a farm is 53kw, among which the largest loads are 24kw, 12kw, 7.5kw, and the rest are others.

If according to the proportion of more than twice, simultaneous start requires a 120kw generator set to operate normally. The price of generator sets: generally, imported generator sets are assembled machines, but for domestic units, there are integrated units, which are comparable to some imported units in performance and cheaper in price. Therefore, when purchasing, we should fully understand the manufacturers and brands of diesel engines, generators and control cabinets of the units to comprehensively evaluate the grade of the units.

However, some machines do not need to be started at the same time. For example, the breeding equipment mentioned above can be started individually: first start the 24kw machine, then the 12kw, and finally the 7.5kw machine. After the high-power machine is started, start all the remaining ones. In this way, the proportioned power of the unit is 75kw, which can meet the start-up and operation of the unit. Some people may not know how to calculate. It's simple, Dingbo Power generator set manufacturer tells you:

A 75kw generator set needs 2-3 times the current to start the first machine, which is 48kw, meeting the starting demand.

After normal operation, it returns to normal, with 51kw remaining. Then start the 12kw machine, which requires 24kw to start.

After normal operation, it returns to normal, with 39kw remaining. Then start the 7.5kw machine, which requires 15kw to start.

After normal operation, it returns to normal, with 31.5kw remaining. The remaining load of the whole system is 9.5kw, which can also be started.

The above calculated power is based on 2 times the current, but in actual situations, it may be calculated according to 2 times, 2.5 times, or 3 times. The specific situation needs to be determined according to the actual situation! The above analysis is for your reference only. If you need to know more professional content, please call Dingbo Power generator manufacturer's professional technicians, so that you can purchase the appropriate diesel generator power and effectively reduce our costs!

2.How to choose the configuration of the generator set

Farm diesel generator sets are generally backup power sources. Generator manufacturers recommend domestic Shangchai and Yuchai engines; if high brand awareness is required, Cummins engines or imported Volvo and Perkins engines can be configured.

Guangxi Dingbo Generator Set Manufacturing Co.,Ltd. was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to [email protected] we will pay highly attention on your question.
