The Chinese market is flooded with many types of diesel generators. You will have a tough time coming to a decision. You should make a thorough research, know your own requirements and then choose the one that you need. Each individual will have different needs. Some will want a diesel generator for the home as a backup when electricity fails. Others might want it in their offices. Still others might want it for agricultural purposes, factories, warehouses and for use at construction sites. Each use will be different and will require a different type of diesel generator. Each will function differently and will be of a different size.
You should first choose the diesel generator according to the power that is needed for your requirement. If it is for a home, the requirement will be different from that in a factory or an agricultural setting. If you are thinking of a generator to function as a standby for your electricity needs, then you should calculate how much power will be needed to run everything in the house as if the power supply is still on. This is necessary because the diesel supply will tell you how long it will be on and how much power you will need to keep the home having the necessary power, in case of a situation without power supply.
There are many models that you can choose from. You have the silent diesel generator which will not make noise. It will be ideal for you home needs and will be the best thing at night, when the whole place is quiet. When you plan on getting a generator only as a backup or for emergency situations, you can get a second hand diesel generator. This will be cost effective and will function properly.
Choose the model with care. Be sure that you do not buy a heavy duty diesel generator that is used in offices, for the home. The generator should suit the demands that are there for your power needs. The details of the generator will be given by the manufacturer. You will be given the output and the speed. The lowest output would be around 5KVA (kilovolt ampere unit). This will be suitable for home needs. Industrial generators can go up to 2500KVA.
The size of the diesel generator will depend on its capacity to generate power and the model that you have chosen. The model should be one that is most efficient and which functions effectively. Know your requirements, study the different types of generators, go to the internet and see what is available. You can also go to the shops, and physically see all the models, the capacities and the sizes and then come to a decision. If you make a wrong choice, you will not the desired result.
As there are many varieties of diesel generators, choosing the right one will indeed be a difficult task. Armed with thorough knowledge about diesel generators, you will be able to come to a conclusion about the one that best suits your own needs. As each and every place and individual has different needs, it is best to take time and study all the aspects of diesel generators. After this you can at last make the final purchase.
Proper sizing of a diesel power generator involves matching performance specifications against real-world operating constraints. If you don’t take the operating constraints into consideration, you will be more likely to encounter problems like nuisance tripping and shortened generator life, even though the diesel power generator specifications may seem adequate (on paper) to handle the load. To help avoid problems, there are three important criteria to consider:
- Environmental Conditions
- Physical Installation
- Connected Equipment
Environmental Conditions
The environment where the diesel power generator will be operated can severely affect the unit’s performance. As the ambient temperature, altitude and humidity increases, the available power of any engine is reduced. This in turn reduces the output of the generator. Increased ambient air over 104 degrees F will also reduce the power capabilities of the AC generator itself. For most applications, moving to the next larger diesel power generator size will insure that ample power is available for all conditions – but this is not always the case.
Physical Installation
Proper cooling and exhaust air flows are the most critical consideration in the physical installation. Inadequate air flow is the most common cause of poor diesel power generator performance and in some circumstances, it can actually lead to complete generator failure. Uninformed users often make the mistake of inadvertently restricting the amount of air flow into and out of the generator housing in an effort to limit noise. In the process, they end up limiting the performance and capability of the unit. It is very important that the heat from the AC generator and the engine cooling system is removed, and must not be allowed to re-circulate back into the enclosure.
Connected Equipment (Loads)
Examples of typical loads include air conditioning units, refrigerators, lights, battery charges/inverters, audio/video equipment and heaters. Simply adding together all the current ratings from the nameplate of each load is not enough to correctly size the generator. For example, the motor and compressor “starting” current on an air conditioning unit will be much higher that the “run” current. If the “run” current is the only thing considered, the diesel power generator selected may be too small to handle the load. Complex engineering calculations are required to determine the total electrical and mechanical demand that will be required so that all the connected equipment will operate as expected.
In short, any overseas customer outside of China, when she or he imports diesel generator set from China, there are some information, needed to be available for the Chinese exporter. Please kindly check the below.
1). Frequency: 50hz or 60hz
2). Single phase or 3 phase
3). Voltage requirement
4). Open type, Silent type, Trailer type or Container type
5). The capacity of diesel fuel tank: 8 hours, 12 hours or longer time
6). Genset panel: standard, auto-start, ATS, paralleled panel, remote panel by PC/laptop in wired/wireless mode.
7). Other requirements
If you are an end-user of diesel generator set, it is better for you to import the diesel gen-set from a professionally trading company involved into diesel generator sets. Of course, you are the distributor or retailer, still can choose a trading company to cooperate if you don’t want to face many problems directly from the Chinese factories who manufacture diesel generator sets. After all, fake Cummins diesel engines are popular in China these years. Anyway, the final decision is still up to you.
Hope the above advices can be valuable for you, help you a lot when you import diesel generator set from China.
