Recently, some customers want to learn about single-cylinder direct-coupled diesel generator sets. For example, the technical parameters, product performance, quality and service of 10kw,12kw and 15kw diesel generators. Generally, if you consult the supplier, they will give reasonable suggestions and configuration parameters according to your actual situation. But for laymen, how to judge the differences, advantages and disadvantages between direct-coupled and belt-driven single-cylinder diesel generators? Let's listen to the following insights.

 

At present, the power of single-cylinder diesel generator sets sold in the market is generally 8KW-24KW, and most products are belt-driven. The main form is that the single-cylinder diesel engine and the generator are fixed through a base, and then generate electricity through belt transmission. It is also the simplest connection method. The single-cylinder direct-coupled diesel generator is directly connected to the generator through the diesel flywheel and various connecting plates to generate electricity.

 

What are the advantages and disadvantages of the two? What are the benefits of this belt-driven diesel generator? As we all know, the general speed of a single-cylinder diesel engine is 2200rpm, while the speed of the generator is generally 1500rpm. By selecting a suitable belt pulley, the speed of the diesel engine and the generator can be better matched. What are the advantages of the newly launched direct-coupled method? It can greatly improve the efficiency of traditional power generation. Because belt transmission has loss or slipping phenomenon. The single-cylinder direct-coupled diesel generator makes up for this shortcoming. It not only has high transmission efficiency, but also high power generation efficiency, which is a worthwhile product to buy.
