What is the difference between a high power diesel generator portfolio brand and a domestic assembly

Comparison of imported and domestic.

1. Quality: The characteristics of the domestic machine are durable and can adapt to the use of the harsh environment, while the imported diesel engine has higher requirements for working conditions, and is generally used as a fire backup and other use environments are better, and it is more suitable to purchase when the number of uses is less.

2. Noise: The nominal value of the decibel of the imported machine is pressed"≥"calculated, while the decibel nominal value of the domestic generator set is pressed"≤"Calculation, this is the reason why the imported machine is much lower than the domestic machine when we look at the technical parameters. In fact, the decibel level of the imported machine is only slightly lower than that of the domestic machine.

3. Maintenance and accessories: domestic machine maintenance is more convenient, especially accessories, many diesel engine accessories can be bought in domestic county-level cities. The characteristics of imported diesel engines are relatively small and there are fewer problems, but it is more difficult to purchase when there is a little failure to replace parts, which affects the work of the enterprise, and is high.

4. Fuel consumption: the same as noise: the imported machine is pressed"≥"calculated, while the domestic machine is pressed"≤"Calculation, the general domestic engine fuel consumption is about 209 grams to 230 grams per kilowatt per hour under full load use, while the imported machine is about 201 grams to 220 grams per kilowatt per hour under full load use.

5. **: In fact, the cost of imported machines is not much higher than that of domestic machines in the case of tariffs, or equivalent to the same model in China, but the sales are much higher than those of domestic generator sets.

6. Base with fuel tank: some imported diesel generator set fuel tanks are equipped at the bottom, with a good overall feeling, compact structure and beautiful appearance. But there are drawbacks:

The bottom fuel tank is usually made of organic synthetic plastic, which is easy to mist with diesel fuel, and domestic diesel contains more organic debris and moisture, which catalyzes this gluing, and the mixture formed by the gluing of this diesel fuel tank will block the oil inlet pipe, resulting in the oil circuit is not smooth and causes the generator set to start difficult, unstable speed after starting, and shutdown for no reason. 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 fuel tank is imported as a random group of unit options, which is higher.

Therefore, it is better for users to use an external fuel tank, which is easy to maintain and maintain, and can also increase the oil inlet pressure. If the bottom tank is already equipped, it is best to raise the unit or set up a sewage pipe to facilitate cleaning and maintenance.

1. Reasonable selection of diesel engine operating conditions.

2. Improve the running-in quality of diesel engine.

3. Select the fuel and lubricating oil suitable for the working needs of the engine.

4. Improve the level of operation technology and carry out maintenance in time.

Reasonable design of the structure and the adoption of necessary technological measures can improve the working performance of the parts and reduce wear. For example, the use of wear-resistant and corrosion-resistant materials to manufacture cylinder liners, the first air ring for porous chrome plating, in addition, the use of high-efficiency air filters, improve the structural performance of the diesel engine cooling system and oil supply system, all of which have a good effect on improving the reliability and service life of Weifang diesel generator sets.

What are you talking about the unit or just the diesel generator, the unit includes a diesel engine and a motor, what brand of diesel engine and motor you want to specify, there is no big difference between joint venture and domestic assembly, but you have to find a good after-sales company.

Domestic assembly machine factories are not authorized to certify OEM technology, may not be able to synchronize after-sales, there will not be too many guarantees.

How to choose a diesel generator set manufacturer.

Diesel generator brands include: Cummins generator set, Fujian Yanan generator set, Yuchai generator set, Weichai generator set, etc.

Many people have no understanding of diesel generator sets before buying diesel generator sets, and only know that they can replace mains. I don't know anything about its production process and various configurations. At this time, the most important point is to choose the right manufacturer, because, because the generator set is a high-tech process product of modern industry, the choice of the manufacturer is quite important.

There are several main considerations for choosing a manufacturer:

First, whether it is at the average level of the same industry, you can shop around; If it's too high, it's not good, and if it's too low, it's definitely not okay. The current ** is quite transparent, if the ** is too low, there must be a problem;

The second is the scale of the company, there is a certain scale of the factory, which is relatively reliable in terms of quality, and at the same time can understand the past sales status of the factory, and if necessary, you can ask for some typical customers, and go to the enterprises that have used the company's products to understand the operation of the unit;

The third is after-sales service, the working conditions of the generator set are very harsh, and machine failures are inevitable, therefore, it is very important to understand the after-sales service capabilities of the manufacturer, such as technical equipment, the number of after-sales personnel, after-sales service vehicles, and the service attitude of technical personnel;

Fourth, accessories and consumables, if it is an imported unit, see whether the manufacturer has enough imported accessories and consumables, because some small factories are in the same industry to transfer goods, accessories and consumables are difficult to guarantee; Buyers can choose the right supplier according to these conditions.

There are too many brands of diesel generators, it depends on the purpose and use requirements of the diesel generator you buy! Now the more commonly used diesel generator set brands in China are: Cummins, Perkins, Yanan, Yuchai, Weichai, Shangchai, Volvo, etc.!

Categorized by use.

1) Commonly used units.

This kind of generator set operates all year round, and is generally located in areas far away from the power grid (or mains) or near industrial and mining enterprises to meet the construction, production and living electricity consumption in these places. In areas with relatively rapid economic development, because the construction of the power grid cannot keep up with the needs of users, the common diesel generator sets with short construction period are set up to meet the needs of users. This type of generator set generally has a large capacity, provides continuous power to non-constant loads**, has no limit on the time of continuous operation, and allows 1 hour of overload power supply time every 12 hours, and the overload capacity is 10% of the rated output power.

Due to its long operating time and heavy load, the allowable power of this type of unit is adjusted to a lower point relative to the limit power of the machine.

2) Standby unit.

Under normal circumstances, the power required by the user is supplied by the mains, and when the mains power is curtailed and the power supply is interrupted or other reasons, the generator set is set up to ensure the basic production and life of the user. This kind of generator set is permanently installed in important power consumption units such as telecommunications departments, hospitals, industrial and mining enterprises with tight municipal power supply, airports and television stations. These units are always on standby and can provide continuous power to non-constant loads**.

3) Emergency unit.

For the electrical equipment that will cause large losses or personal accidents due to the sudden interruption of the mains, emergency generator sets are often set up to provide emergency power to these equipment, such as the fire protection system of high-rise buildings, evacuation lighting, elevators, control systems of automated production lines, important communication systems and medical equipment that are performing important surgeries with patients. This kind of unit should be able to start operation quickly when the mains power is suddenly interrupted, and provide stable AC power to the load in the shortest time to ensure timely power supply to the load, and the degree of automation of this kind of unit is relatively high.

With the development of industry, generator sets as emergency backup power supply has become indispensable, what need the owners to pay attention to when purchasing emergency generator sets?

1. The rated power of the generator set is kva and kw, but 1kw =, that is, the power of the 500kva genset is 400kw.

2, to refurbished machine or second-hand pretending to be a new machine, brand diesel engine has a unique serial number in the world, the owner bought the generator set, you can check these serial numbers on the Internet, refurbished machine or second-hand phone will definitely appear use information.

3. The generator set uses inferior or unqualified raw materials.

There are many genset brands, such as Yanan Yanan diesel generator set, users can choose according to their budget. However, the general unit has different uses (as a common power supply or a backup power supply), different use environments and different power of the unit, and the recommended unit brands are different! Users should choose the right unit according to the specific work needs!

Whether the oil generator set is used as the main power supply or standby power supply, it provides great convenience for our production and life, and customers have more or less doubts when purchasing generator sets: which brand of generator sets is reliable?

The power of the generator set is 8-2000kw, according to the appearance style, the generator set has fixed generator set, mobile generator set, silent generator set, container generator set, etc.; According to the automation level, the generator set includes dashboard generator set, four-protection generator set, self-starting generator set, automatic generator set, cloud service generator set, etc.

There are many brands of generator sets, including Yuchai generator sets, Jichai generator sets, Weichai generator sets, Cummins generator sets, Perkins generator sets, Volvo generator sets and other domestic and international brands.

The purchase of generator sets still needs to be taken seriously by the owner, according to the actual situation of the electrical equipment, the location of the generator set, the owner's requirements for the automation level of the generator set, the owner's budget, etc. to determine the style and automation level of the generator set; According to the pre-sale, in-sale and after-sales service of the generator set manufacturer, the production capacity of the manufacturer, the innovation and development of the manufacturer, etc., the generator set manufacturer is determined.
