Advantages And Disadvantages Of Imported And Domestic Diesel Generator

For users eager to purchase diesel generator sets, it is a headache to choose imported or domestic ones. When making a purchase, one should objectively analyze its advantages and disadvantages, such as comprehensively measuring quality, price, noise, fuel consumption, etc. Below, the editor of Starlight Power will learn together with everyone.

1. Quality.

Many consumers think that the quality of domestic diesel generator is not as good as that of imported ones. In fact, with the progress of domestic science and technology and the improvement of productivity, domestic diesel generator are also very secure. The key is whether you buy genuine products. For example, the quality of Jiangsu Starlight Power is good. It was founded in 1974. The professional generator and diesel generator manufacturers are also very guaranteed after sales. If you buy fake goods, their quality will naturally be poor. The counterfeiting of imported diesel generator sets is also very serious, and the quality is also poor. When the refurbished imported diesel engine is not actually used, many insiders are unlikely to identify it by its appearance, but the counterfeit domestic diesel generator set can be identified by professionals at will.

To avoid counterfeit products, most brands of imported generators are not of better quality than domestic ones, and even some brands are not as good as some of the domestic brands. The characteristics of domestic engines are durability and adaptability to harsh environments, while imported diesel engines have high requirements for working conditions and are generally used as fire backup in good environments. It is more suitable to purchase them when used less frequently.

2. Price.

In fact, the cost of imported machines, including tariffs, is not much higher than that of domestic machines, or equivalent to the price of the same model in China, but the sales price is much higher than that of domestic generator sets. This is also a complete set of imported diesel engine manufacturers who fully utilize the mentality of Chinese people worshiping foreign countries to earn high profits. But now the prices of imported diesel engines of certain brands are far lower than those of domestic diesel engines of the same power, and the reason for this is not convenient to "speculate" here.

3. Noise.

The nominal decibel value of imported machines is calculated based on "≥", while the nominal decibel value of domestic generator sets is calculated based on "≤". This is why when we look at technical parameters, imported machines have much lower noise than domestic machines. In fact, the decibel of imported machines is only slightly lower than that of domestic machines. Whether it is an imported machine or a domestic machine, as long as it is equipped with a complete set of formal factory matched silencers, the noise emitted can meet national standards. Moreover, the computer room can also isolate a portion of the noise. People can hardly feel much noise outdoors.

4. Fuel consumption.

Same as noise: Imported machines are calculated based on "≥", while domestic machines are calculated based on "≤". Generally, domestic machines consume around 209 to 230 grams of oil per kilowatt hour under full load use, while imported machines consume around 201 to 220 grams per kilowatt hour under full load use. Users can calculate a reasonable purchasing plan based on the price difference between imported and domestic machines, combined with their actual usage time.

5. The base is equipped with an oil tank.

Some imported diesel generator sets are equipped with oil tank at the bottom, which has a good overall feeling, compact structure and beautiful appearance. But there are also drawbacks: the bottom oil tank is usually made of organic synthetic plastic, which is easy to dissolve with diesel. Domestic diesel contains more organic impurities and moisture, which further catalyzes this bonding. The mixture formed by the bonding between diesel and the oil tank can block the oil inlet pipe, causing the oil circuit to be blocked and causing difficulties in starting the generator set, unstable speed after starting, and unexpected shutdown.

6. Maintenance and accessories.

No matter how good the quality of the generator set is, it cannot be without faults. If there are problems, they involve maintenance and accessories. Domestic engine maintenance is relatively convenient, especially for accessories. Many diesel engine accessories can be purchased in county-level cities in China. The characteristic of imported diesel engines is that they have relatively few problems, but in case of any malfunction, parts need to be replaced, and the price and cost are relatively high.

For example, buying a new oil pump for a domestic diesel generator set is only 1/4 to 1/3 of the cost of calibrating the oil pump for an imported diesel engine, which is not disastrous for enterprises. If you want to replace parts, you can only ask the headquarters for goods, which may take several months. During this time, the diesel generator is just a pile of scrap iron in the corner, and many of the enterprise's work may be delayed.

And the bottom oil tank is not easy to drain and maintain, resulting in the formation of oil deposits. In addition, the bottom oil tank, as an optional component of the unit, is randomly imported and has a higher price. Therefore, it is best for users to use an external fuel tank, which is convenient for maintenance and upkeep, and can also increase the inlet pressure. If a bottom oil tank is already equipped, it is best to elevate the unit or set up a sewage pipe for easy cleaning and maintenance.
