Sales of new Shandong Weichai, Guangxi Yuchai, Shanghai Diesel, Dongfeng Cummins, Chongqing Cummins, and Rolls-Royce diesel generator sets. 3. Sale and recycling of second-hand diesel generator sets ranging from 100KW to 2000KW from various brands.
Selection of emergency generators. It is generally advisable to choose high-speed, supercharged, low fuel consumption, and the same capacity generator sets. High-speed supercharged diesel engines have larger individual capacity and occupy less space; diesel engines should be equipped with electronic or hydraulic speed regulation devices for better speed regulation performance; it is recommended to use synchronous motors with brushless excitation or phase-regenerative excitation devices for generators, which offer greater reliability, lower failure rates, and easier maintenance and repair; when the capacity of a single air conditioner or motor in the primary load is large, it is advisable to select a generator set with three times harmonic excitation; the set should be mounted on a common chassis with shock absorbers; a silencer should be installed at the exhaust pipe outlet to reduce the impact of noise on the surrounding environment.
(1) Determination of Capacity: Emergency generators are used for emergencies, often in standby emergency start-up mode, with a short continuous running time, generally not exceeding 8 hours. Therefore, capacity can be determined based on "standby power." Consider the sum of the capacity of primary loads (excluding reserve capacity), taking into account the adjusted generator capacity, and ensuring it can meet the start-up requirements of one motor in the primary load. Based on this, determine the capacity of the emergency diesel generator set. Emergency generators typically use three-phase AC synchronous generators with a rated output voltage of 400V.
(2) Quantity Determination: Generally, a generator set is selected with 1 unit of automation, speed of 1000-1500 RPM, brushless excitation, 400/230V, three-phase four-wire with control panel, charging/discharging equipment, and a shared base plate. It is possible to request a shared base plate with a daily oil tank to reduce pipeline and area usage. Alternatively, for reliability, two units can be paralleled for power supply. The number of emergency generator sets supplied should generally not exceed 3. When selecting multiple units, the sets should be as similar as possible in model and capacity, with similar voltage regulation and speed regulation characteristics, and the fuel type should be consistent for ease of maintenance and shared spare parts. We promise satisfaction through advanced technology equipment, thorough service, and zero faults in field use. To express our gratitude to our customers, we provide top-quality equipment and dispatch skilled technicians to operate the equipment. Our equipment is all imported or domestically original, including brands such as Cummins, Fengren, Caterpillar, Daewoo, Weichai, and Shangchai, among others.
