What should I pay attention to when choosing a generator set? Many users will encounter such problems, especially for some new users of generator sets. First of all, to ensure the quality and after-sales service of the selected generator generator set, it is necessary to choose the OEM factory of a well-known diesel engine manufacturer.

Secondly, it is necessary to pay attention to the brand and configuration selection of the unit, as well as the mechanical and electrical performance of the unit, the purpose of the unit, the capacity and range of change of the load, and the automation function.

There is another problem that users are easy to ignore, that is, the freight of the unit, which must be clearly communicated with the manufacturer. The specific matters are not listed one by one. In the process of actually choosing the generator set, the user should choose according to the actual situation!

A diesel generator is a device that converts the bioenergy of diesel into electrical energy, which can be used as a prime power source or as a backup power source. What pitfalls will you encounter when buying a generator set? Hopefully, these will be helpful to the owners who are about to buy generator sets.

The general power of the generator set is from 8 to 2000kw, and the diesel generator brands include Cummins generator, Perkins generator, Volvo generator, Doosan Daewoo generator, Yuchai generator, Weichai generator, Shangchai generator and other brands. Generally, diesel generators include stationary generators, mobile generators, silent generators, containerized generators and other styles.

When the owner chooses the generator set, the reference basis is: the amount and power of the electrical equipment, the environmental requirements for the use of diesel generators, the requirements for the automation level of diesel generators, the owner's budget and so on.

According to the requirements of generator set selection, the owner selects the appropriate generator set, and then selects the appropriate generator set manufacturer according to the production capacity, innovation ability, pre-sale, after-sales service ability and so on.

So what do owners need to pay attention to when buying 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.

To buy a generator set, it is recommended to shop around and visit the generator set manufacturer before deciding.

The purchase of small diesel generators must first have a clear positioning, whether the purchased generator set is standby or commonly used. If the generator you buy takes a lot of time and is more commonly used, it is recommended to buy an imported generator set.

Then according to the size of the load used, the power of the diesel generator set is selected. It is best to use the common load at about 80% of the rated power of the diesel generator set. Because the diesel engine is the most fuel-efficient when the load is 80% of its rated power, it is also a kind of protection for the diesel engine itself.

Finally, it is necessary to pay attention to determine the brand and power size, and it depends on the configuration of the generator set. Just like buying a car, you mainly look at these three parts: the diesel engine, the generator and the control system.

The quality of the generator is related to the stability and service life of the voltage. The control system is preferably computer-controlled, which has a good protection effect on the generator.

The factors that should be considered when purchasing a generator set are mainly the mechanical and electrical properties of the rolling family, the purpose of the unit, the capacity and variation range of the load, and the automation function.

1. The purpose of the generator set. Because the diesel generator set can be used in 3 situations, such as common, standby and emergency. Therefore, the requirements for generator sets are different for different uses.

2. The load capacity of the generator set. The load capacity and load change range should be selected according to different uses, and the single capacity of the power generation unit and the standby diesel generator set capacity should be determined.

3. The environmental conditions for the use of the generator set (mainly referring to the altitude and climatic conditions).

4. The selection of generator bucket preparation group.

5. When purchasing a generator set, pay attention to the generator and excitation mode.

6. The selection of the automation function of the generator set.

Diesel generator set is a diesel generator set fueled by diesel, which is generally composed of diesel engine, generator, control box, fuel tank, starting and control battery, protection device and other components.

When users buy diesel generators, they only pay attention to their performance, generators, energy consumption is not enough, but also to understand the selection point of diesel generator sets, in this regard, many users are confused, do not know enough about diesel generator sets, and confuse the role of main power in diesel generator sets.

There are 2 kinds of diesel generator sets with common power and standby power, the domestic power is subject to the common power, and the foreign power is subject to the standby power, and the standby power is generally larger than the commonly used power, so the domestic should pay attention to distinguish.

The relationship between the power unit kw and kva of diesel generator set: kw is the unit of power, generally 1kva=, do not confuse kva and kw when purchasing.

No matter which diesel generator set manufacturer's diesel generator set, there is no unified, and the specific unit is different depending on the brand, configuration and power of the unit (how many kw).

To know the specific information of the unit, it is necessary to understand the basic information of the unit: the brand of the unit, the configuration of the unit, the power of the unit, and whether the unit is a brushed diesel generator set or a brushless diesel generator set.

When purchasing the manufacturer's generator set, the manufacturer will give **, and then choose the right unit according to your needs!

1. First of all, we should pay attention to the selection of diesel generator set manufacturers, and pay attention to the first is the first of the manufacturers' units, whether they are at the average level of the same industry, and you can shop around. The second is the scale of the company, which has a certain scale of factories and is relatively reliable in terms of quality. The third is after-sales service.

Fourth, accessories and consumables, if it is an imported unit, see whether the manufacturer has enough imported accessories and consumables.

2. Pay attention to the relationship between KVA and KW. The relationship between them is ikva=. Imported diesel generator sets generally use KVA to express the power unit, while domestic electrical equipment is generally expressed in KW, so KVA should be converted into KW by 2% when calculating power.

3. The relationship between the long line (rated) power and the backup power, only one "power", and the backup power is sold to customers as the long line power. Actually, backup power = long line power. Moreover, the backup power can only be used for 1 hour of 12 hours of continuous operation.

4. The purpose of the unit. Because the diesel generator set can be used in 3 situations, such as common, standby and emergency. Therefore, the requirements for diesel generator sets for different purposes are different.

5. Load capacity. The load capacity and the load change range should be selected according to different uses, and the single capacity of the diesel generator set and the standby diesel generator set capacity should be determined.

6. The use of environmental conditions of the unit (mainly referring to altitude and climatic conditions) The selection of diesel generators, the selection of generators and excitation methods, and the selection of automation functions of diesel generators.

When buying a generator set, there are the following points that need to be paid more attention to by owners and friends:

1. The owner should understand what the electrical equipment is, what is the power, whether the generator set is used as the main power supply or backup power supply, and then finalize the power of the required generator set.

2. The owner should confirm the use environment of the generator set, whether it is used outdoors or indoors, and whether it needs to be moved frequently. This is used to finalize the style of the generator set.

3. The owner's requirements for the degree of automation of the generator set and cloud services, etc.

4. Finalize the diesel engine and generator brand of the generator set according to the budget.

5. The owner looks for multiple generator set manufacturers on the Internet, and comprehensively compares the manufacturer's production capacity, research and development capabilities, pre-sale, in-sale and after-sales service capabilities to finalize the diesel generator manufacturer.

The choice of generator set manufacturers is, of course, to choose the OEM factory of a well-known diesel engine manufacturer, so that the quality and after-sales service of the unit are excellent.

Users can purchase online or visit the site, but be sure to pay attention to this.

Also pay attention to the choice of unit brand, the following introduction as a reference, normal standby or occasional use, 50-150 is recommended to use Shangchai diesel generator set, 150-300kw is recommended to use Yuchai diesel generator set, 300kw-1200kw is recommended to use Cummins diesel generator set, such a choice is the best choice combined with quality.

The configuration of the unit should be selected according to the needs of the work!

When choosing a generator set, we should first pay attention to the selection of regular manufacturers, the quality and after-sales of regular manufacturers.

1. First of all, you must figure out the type and power of the equipment you buy with the generator, communicate with the dealer, and confirm how much power the generator to buy. In this way, we can avoid the waste of buying a large amount of equipment and the situation that you can't bring the equipment if you buy a small one.

2. Check that the generator set certificate includes the production license, product qualification certificate, trademark registration certificate, and other 'three certificates'.

3. Check whether the information provided is consistent with the actual information. There is a nameplate on the generator, the internal combustion engine, and the whole machine.

4. Choose after-sales service: When buying generators, it is recommended to buy products from well-known brands and regular manufacturers.
