1. Select the appropriate model: the selection of generator sets is very critical. Too large selection will increase the cost, and too small selection cannot meet the electricity requirements.
It is recommended to first calculate the detailed electricity consumption list in detail. For example, the electricity consumption is 80KW. Considering the starting current of the electrical appliance, it is usually calculated as follows: 80KW*1.25=100KW. If the electrical equipment has a large inductive load, its instantaneous starting current should also be considered for selection.
2. Choose the integrity of the enterprise: After the selection is determined, it is very important to choose a company with a good integrity. An enterprise with a good integrity is the most reliable partner. Only honest and trustworthy enterprises can provide you with high-quality products and perfect services. Whether it can create value for customers and win-win with customers, the integrity of an enterprise is very important.
3. Configuration of generator set: The generator set is mainly composed of diesel engine, generator and control system. The level of quality and the level of price are reflected in these three parts.
3.1 The configuration of international high-end brand units is as follows:
Brand products The complete sets of generator sets are international high-end brand products with high price and good performance. The three parts of the generator set are imported.
3.2. The configuration of domestic high-quality brands is as follows:
Diesel engine brands include Shangchai Co., Ltd., Yuchai, etc. It is recommended to use deep sea and other brands for the control system. The generator set configured in this way is more cost-effective and has better service. Compared with high-end products produced internationally, it is a mid-end product.
3.3, low-end models, poor quality and performance, no guarantee of after-sales service, do not recommend customers to choose.
4. Selection of special models
4.1. The automatic model can realize unmanned operation. After the mains power failure, the generator can automatically start and supply power automatically.
4.2. The grid-connected unit can realize the parallel operation of multiple units, the parallel operation of electromechanical and grid power, and the parallel operation of small units to replace large units, which effectively reduces the procurement cost.
4.3. Mobile power station, four-wheel mobile trailer, stable walking, flexible, rain-proof and noise-reduced, suitable for customers who do not have a fixed location for generating sets such as urban field operations.
4.4. The rain cover unit, closed system, large-capacity base-type fuel tank, can reduce part of the noise, prevent rain and dust, reduce the floor space, and replace the generator room. Investment is more convenient to use.
4.5. The low-noise unit can effectively reduce the operating noise of the generator set, reduce urban noise and treat the exhaust gas, eliminate the need to build a generator room, save land area, beautiful appearance, more environmentally friendly, and the location can be moved.
4.6. In addition, low-noise automatic units, mobile low-noise units, mobile automatic units, low-noise grid-connected units and other models are available for customers to choose.
5. Reasonable configuration of the generator set. The industry stipulates that the diesel engine power is greater than or equal to 10% of the rated power of the generator. The reason is that there is mechanical loss. However, some manufacturers in the industry now configure the 1-hour power of the diesel engine and the power of the generator to be the same size in order to reduce costs. The model configured in this way is commonly known as “small horse-drawn cart”, which not only seriously affects the performance and service life of the generator set, but also consumes high fuel, increases the cost of use, and may cause the generator set to be scrapped and serious property damage in an instant.
