1. Product Overview
Zichai and Jichai gas generator sets drive the engine to work using coalbed methane, coal-to-coal gas, wood-to-furnace gas, blast furnace gas, coking furnace gas, etc. In the utilization of primary energy in today's world, an obvious trend is the gradual development of coal and oil to the greater use of combustible gas. This is because coal and oil are polluted severely and transported large amounts. Our country has rich gas resources. These gas sources can be used by the 300 series gas gas engines after treatment. The 300 series gas gas engine has broad development space.
2. Advantages of products of Zichai and Jichai gas generator sets
Good power generation quality. Since the generator set only rotates when working, the electro-modulation reaction speed is fast and the work is particularly stable. The generator output voltage and frequency are high and the fluctuations are small. When the load is increased or decreased by 50% and 75% of the load, the unit is very stable. Electrical performance indicators that are better than diesel generator sets.
Good startup performance and high startup success rate. The time from the successful start of cold state to full load is only 30 seconds, and the diesel generator is required to be loaded 3 minutes after successful start of cold state. Gas turbine generator sets can ensure success rate of start-up at any ambient temperature and climate.
Low noise and low vibration. Since the fuel turbine is in a high-speed rotation state, its vibration is very small, and the low-frequency noise is better than that of the diesel generator set.
3. Fault analysis
When a fault occurs, pay attention to analyzing the cause of the fault from the fault phenomenon, and analyze the structure based on the principle, from the inside to the inside, it is easy first and then difficult. The following three issues should be considered when a gas generator set of Zichai and Jichai are malfunctioning:
What happens before the failure occurs?
What maintenance and maintenance work were carried out before the failure occurred?
Have you encountered similar situations before? How to deal with it? In addition, when the Zibo and Jichai gas generator sets allow you to determine the problem during operation, you can make a judgment during operation.
