Cooling Options for Emergency Backup Diesel Generators

As the temperature rises slowly, the heat dissipation and noise reduction of diesel generator sets become the focus of attention. What are the precautions for reducing noise and heat dissipation in diesel generator room? First of all, in the design of emergency diesel generator room noise reduction, we should consider the ventilation of the engine room. The volume of ventilation is calculated on the basis of the amount of air needed for engine combustion and the amount of air exchange required for the heat dissipation of the generator set. The sum of gas and air exchange is the ventilation of the engine room. This is a change value, which is the temperature rise of random rooms. When considering the noise reduction in the computer room, the ventilation rate of the computer room should be strictly according to the standard, that is, the temperature rise of the engine room should be controlled within 5 ℃ , and the ventilation required by the unit is the largest. Se...

How to Buy a Used Diesel Generator Set

Buying a new diesel generator set requires only a good brand and manufacturer. Generally, there is no problem, but some customers will purchase a second-hand diesel generator set as a backup power source for the purpose of saving production costs. Be more careful when you choose. When purchasing a second-hand diesel generator set, you should pay attention to these aspects: Some customers tend to consider buying diesel generator sets  in order to save costs. There are many places to identify when purchasing a second-hand diesel generator set. If you are not an expert, it is difficult to buy a second-hand unit with practical value. So what issues should you pay attention to when buying a second-hand generator set? 1. Need to know the purchase time, use and reasons for the sale of used diesel generator sets, ask about the past maintenance situation, change the important parts, ask what problems in the use, in order to have a more comprehensive system of second...

Location and Drainage of Silent Type Diesel Generator

The choice of silent type diesel generator  room is always a problem encountered by customers. It is very important to select a good installation position of diesel generator set, which is related to the future use and maintenance of the generator set. So how to select the location of silent diesel generator room? 1. The location of diesel generator room takes into account the intake of diesel generator, smoke exhaust and so on. If conditions are available, the genset room is best located on the first floor. However, high rise buildings are expensive, especially the first floor usually used for external business. As a result, generator rooms are generally located in the basement. As the basement is not suitable for entry and exit and the natural ventilation condition is poor, it brings a series of unfavorable factors to the design of the genset room, which should be handled well in the design. Attention should be paid to the following points when sele...

Balance the Power Distribution of Parallel GenSet

Parallel connection of diesel generator sets should first meet the requirements of even power distribution. The even distribution of power includes both active power and reactive power. The so-called uniform distribution means that the active power and reactive power of each generator should be proportional to their rated power. There are clear requirements for the power distribution of parallel-operated generator sets in China, when the alternator sets are operated in parallel. When the load changes within the range of 20% to 100% of the total rated power, it should be able to operate stably, and its power distribution error should meet the following requirements. 1. The difference between the actual active power of each generator and the calculated value according to the rated power ratio shall not exceed ± 10% of the rated active power of the generator when the rated power of the generator is the same; when the rated power of the generator is different, Should...
