What is the appropriate load for diesel generator sets?

The key is to choose the power of the diesel engine first. In the past, there were customers. The Planning Institute gave 100kW, but specifically promoted two centrifugal pumps. In fact, there is no doubt that it is not only 100kW. Therefore, when the customer determined the output power, it was only when professional technicians communicated clearly with your requirements that the necessary output power was determined.

Many diesel generator customers have always regarded their power load as strong when purchasing Guizhou diesel generator set in order to save costs. If your load is more than 200kW, you just want to buy a 200kW diesel generator. This kind of idea is not available. The long-term full load operation of diesel generator will cause great damage to the crankshaft of cylinder engine and reduce the service life of diesel generator.

On the other hand, some customers are always afraid that the power from their diesel generators is insufficient for their own applications, and have always wanted to buy large diesel generator sets. For example, its specific load can only be 30kW, but it is not available to buy a 200kW diesel generator. 1、 Such application will lead to great luxury and waste and increase fuel consumption. 2、 The diesel generator set is in low load operation for a long time, and the ignition of the diesel engine is insufficient. After a long time, the carbon deposition of the diesel generator is relatively serious, which is very harmful to the diesel generator.

The proper selection should be: when the load of diesel generator is 80%, it is suitable, and the generator set can not operate for a long time under the condition of load less than 50%. The key reason is: generally, the specific situation is that when the load is 80%, the fuel consumption is low. If the load of diesel generator is 80% of the rated value, one liter of oil generates 4 degrees of electricity, and if the load is increased, The fuel consumption will rise, which means that the fuel consumption of diesel generator is directly proportional to the load. However, if the load is less than 20%, it will be harmful to the diesel generator, which will not only greatly increase the fuel consumption of the generator set, but also destroy the diesel generator.

Therefore, the output power of the diesel generator should be selected effectively, which can not only save the diesel generator from overweight operation, but also ensure that the diesel generator is not easy to operate under low load for a long time, so as to increase the service life of the diesel generator.
