Many users in the purchase of diesel generator set, the brand choice of diesel generator set is more difficult, do not know what diesel generator set brand quality is good, do not know which is domestic diesel generator set, which is imported diesel generator set. So the difference between imported diesel generator sets and domestic diesel generator sets?
1. Base with fuel tank
Some imported diesel generator tank is equipped at the bottom, the overall sense is better, compact structure, beautiful appearance. However, there are also disadvantages: the bottom tank is usually made of organic synthetic plastic, which is easy to dissolve similar to diesel, domestic diesel contains more organic debris and water, but also catalyzes this bonding, the mixture formed by the bonding of diesel and the fuel tank will block the inlet pipe, resulting in the oil circuit is not smooth and cause the generator set to start difficult, unstable speed after starting, unexplained shutdown and other failures. The oil tank at the bottom of the machine is not easy to drain and maintain, so that the oil is deposited.
In addition, the bottom tank is imported with the diesel generator set as an optional part, and its price is higher. Therefore, it is good for users to use an external fuel tank, which is easy to maintain and maintain, and can also increase the fuel pressure. If it is equipped with a bottom tank, it is good to raise the unit or set up a blowdown pipe for easy cleaning and maintenance.
2. Maintenance and accessories
No matter how good the quality of the diesel generator set is, there can be no fault, and the problem involves maintenance and accessories.
Domestic diesel generator set maintenance is more convenient, especially parts, many diesel engine parts can be bought in the domestic county cities.
Imported diesel engines are characterized by relatively few small problems, but in case of a little failure to replace parts, and the price is higher. Such as: Domestic diesel engine oil pump to buy a new only imported diesel engine school oil pump cost 1/4 to 1/3, which is not disastrous for the enterprise, if you want to change parts can only to the headquarters for goods, this mess may take several months, and during this time the diesel generator set is purely a pile of scrap in the corner, A lot of work in the enterprise may have to stop.
3. Noise
The decibel nominal value of the imported diesel generator set is calculated according to “greater than”, and the decibel nominal value of the domestic machine is calculated according to “less than”, which is why we look at the technical parameters when the imported diesel generator set noise is much lower than the domestic machine. In fact, the decibel of the imported diesel generator set is only slightly lower than that of the domestic machine.
Whether it is an imported machine or a domestic machine, as long as it is equipped with a regular complete set of silencers, the noise emitted can meet the national standard, moreover, the machine room can also isolate part of the noise. People in the outdoor is basically can not feel much noise.
The above is the difference between imported diesel generator sets and domestic diesel generator sets? Hope to help you, more diesel generator information welcome to contact.
