What factors should be considered when renting construction site generators?
Generator rentals often require differentiation based on different regions and usage requirements. For small-scale generator rental sites and large-scale generator rental sites, the generators we provide are also different. One of the common locations for generator rentals is construction sites. Today, Shandong Generator Rental analyzes the selection factors to consider when renting generators for construction sites.
Construction Site Generator Rental: How to Choose
(1) Factors to consider include the category of electrical equipment, the main motor's power, starting method, and starting rules, among others. It's important to note that the power of a single motor is extremely high, thus diesel generator sets must have excellent starting performance to avoid increasing the investment budget for the generator sets.
(2) Large motors used on construction sites share a common characteristic: they have a high starting load and a low operating load. Poor calculation or starting mode can lead to significant waste of human, material, and financial resources. Currently, there are several types of motor starting methods: direct starting, autotransformer降压 starting, soft starting, variable frequency starting, and star-delta starting, among others. Motors used on construction sites are mostly large capacity motors, with fewer direct starting applications. Therefore, a comprehensive choice can be made based on one's investment budget, and communication with equipment manufacturers and generator set manufacturers is recommended to select a more suitable solution. After choosing the starting method, calculate the starting current (under poor conditions) and operating current for all equipment, and then determine the amount of power the generator set needs to be configured with.
(3) Due to the extremely harsh operating conditions of the diesel generator sets used at the construction site, some locations are even at high altitudes. As the power capacity of diesel generator sets decreases with increasing altitude, this factor must be taken into account to avoid the drawback of purchasing a power output that does not match the actual operating power.
