Due to remote region and the long distance for power supply transmission line, the construction site needs to be equipped with suitable diesel generator sets to provide power supply.
So what should we pay attention to when purchasing diesel gen-set on the construction site? Since the diesel generator set used on the construction site requires higher electricity consumption than the conventional site, users should be more cautious.
1. Firstly, it is necessary to consider various factors such as the type of electrical equipment, starting method, starting rule, etc. As the power of a single generator is generally very large for the equipment on the construction site, diesel generator sets are required to have excellent starting performance.
2. Diesel generators used in construction sites have a common feature, that is, the starting load is large but the load after operation is small. At present, the starting methods of generator generally include: direct start, self-coupling decompression start, soft start, variable frequency start, star-delta start, etc. Most of the large-capacity generators used on the construction site are rarely started directly. You need to make a comprehensive selection according to your own investment budget, communicate with generator set manufacturers, and select the best and appropriate plan. After selecting the starting mode, calculate the starting current (during the worst working condition) and operating current of all equipment, and finally calculate how much power diesel generator set needs to be configured.
3.Because working environment of the construction site is very harsh, and some places are even in high-altitude areas, and the power carrying capacity of diesel generator sets decreases with the increase in altitude, it is necessary to take the altitude factor into consideration, otherwise it will cause the power output of the purchased diesel generator set does not match the actual operating power.
Which brand of engine for diesel generator set is recommended for construction site to be more durable? Cummins, Deutz, Yuchai, Shangchai and other series are more recommended. If budget is sufficient, the imported brands, such as Volvo, Doosan, MTU, Perkins, etc. could be considered, which are more suitable for use in complex conditions on the construction site.
