Diesel Generator sets
Diesel engine and parts
Which is better, imported generator set or domestic generator set?
May 17, 2022
There is a big difference between imported generator sets and domestic generator sets, as well as standby generator sets and common generator sets. Compared with domestic generator sets, imported generator sets have their own advantages and disadvantages; The price and brand of diesel generator sets, while the price of imported diesel generator sets is generally higher, and the price of domestic diesel generator sets is slightly lower. JUNVOCH recommends that users should analyze and compare objectively and rationally from the following aspects when purchasing:
1. The quality of diesel generator sets
Most consumers generally believe that the quality of domestic generator sets is not as good as imported generator sets. In fact, the quality of domestic diesel generator sets is already very good. The key is whether it is the original authentic products. The domestic diesel generator sets produced and sold by Dingbo Power are original and authentic generator sets. Guaranteed brand new; if you buy a fake or refurbished unit, the quality is really bad. When refurbished imported diesel generator sets are actually used, many experts are unlikely to distinguish them by appearance, but fake domestic diesel generator sets can easily be identified by experts. The characteristics of domestic diesel generator sets are durable, It can adapt to the use of harsh environments, while imported diesel generator sets have relatively high requirements for working conditions. Generally, they are used as fire protection backup and other use environments.
2. Noise of imported diesel generator sets
Noise of diesel generator sets: The nominal value of decibels of imported diesel generator sets is calculated according to "≥", while the nominal value of decibels of domestic diesel generator sets is calculated according to "≤". This is when we look at the technical parameters of imported diesel power generation. The reason why the unit is much lower in noise than the domestic diesel generator set. In fact, the decibel of the imported machine is only slightly lower than that of the domestic machine. Regardless of whether it is an imported diesel generator set or a domestic diesel generator set, as long as a regular complete set of mufflers is installed, the noise emitted can meet the relevant standards. Moreover, the diesel generator set room can also isolate part of the noise. People don't feel much noise when they are outside.
3. Maintenance and accessories of diesel generator sets
Any equipment used for a long time will inevitably fail, and if there is a problem, it will involve maintenance and accessories. Domestic diesel generator sets are more convenient to maintain, especially accessories. Many diesel generator sets can be purchased in domestic county-level cities. The characteristics of imported diesel generator sets are that there are relatively few problems, but in case of a little failure, the parts need to be replaced, and the price is high. For example: Buying a new oil pump for a domestic diesel engine is only 1/4 to 1/3 of the cost of an imported diesel engine for an oil pump. This is not catastrophic for enterprises. If you want to replace parts, you can only ask the headquarters for goods. , this tossing may take several months, and during this time, the diesel generator is just a pile of scrap iron in the corner, and many work of the enterprise may be stopped.
4. Fuel consumption of diesel generator set
The same as the noise: the imported machine is calculated according to "≥", while the domestic diesel generator set is calculated according to "≤". Generally, the fuel consumption of domestic diesel generator sets is ≤209 grams to 230 grams per kilowatt hour under full load use. , while the imported diesel generator set is ≥201 grams to 220 grams per kilowatt hour under full load use. When purchasing, users can calculate a reasonable purchasing plan from the price difference between the imported diesel generator set and the domestic diesel generator set combined with the actual use time they need.
5. The price of diesel generator set
In fact, the cost of imported diesel generator sets is not much higher than that of domestic diesel generator sets with tariffs included, or is equivalent to the price of the same domestic model, but the sales price is much higher than that of domestic diesel generator sets. This is also the complete set of imported diesel engine manufacturers making full use of the psychology of some Chinese people to make high profits. But now the price of imported diesel generator sets of some brands is much lower than the price of domestic diesel generator sets of the same power.
6. The base of the diesel generator set has a fuel tank
Some imported diesel engine fuel tanks are equipped at the bottom, which has a good overall feeling, compact structure and beautiful appearance. But there are also disadvantages: the bottom fuel tank is usually made of organic synthetic plastic, which is easily compatible with diesel fuel. Domestic diesel contains more organic debris and moisture, which catalyzes this kind of gluing. The mixture formed by the gluing of diesel and fuel tank It will block the oil inlet pipe and cause the oil circuit to be unobstructed, resulting in difficulty in starting the generator set, unstable rotation speed after starting, and shutdown for no reason. The bottom oil tank is not easy to drain and maintain, so that the oil deposits are formed. Therefore, Tingbo Power recommends that users still use an external fuel tank, which is convenient for maintenance and maintenance, and can also increase the oil inlet pressure. If it has been equipped with a bottom fuel tank, it is better to raise the unit or set up a sewage pipeline for easy cleaning and maintenance.
