2017 auto parts: China turnover contribution will reach 39%
The China Business Industry Research Institute's "Analysis Report on China's Auto Parts Market Potential and Investment Prospects from 2015 to 2020" pointed out that the turnover of China's auto parts market from 2011 to 2015 will grow at a compound annual growth rate of 12.4, and will further grow at a compound annual growth rate of 7.6 from 2015 to 2017, which is higher than the global market growth rate during the relevant period. The competitiveness of China's auto parts in the global market is becoming increasingly strong.

Functional characteristics of the generator
The voltage change rate of the synchronous generator is about 20-40%. General industrial and household loads require that the voltage remain essentially constant. For this reason, as the load current increases, the excitation current must be adjusted accordingly. Although the trend of the adjustment characteristics is the opposite of the external characteristics, it rises for inductive and purely resistive loads, and generally decreases under capacitive loads.

Operating Procedures for Generators
Before starting, check whether the fuel tank is sufficient, and there is no oil leakage at the oil pipes and joints; whether the water in the cooling system is sufficient, clean and free of leakage, and whether the fan belt is properly tightened. Check that the internal combustion engine and the generator drive part should be connected reliably, the wires of the output circuit should be well insulated, and all instruments should be complete and effective.

The working principle of the generator
Whether it is a diesel generator or a gasoline generator, each cylinder performs work in a certain order. The thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. By installing the brushless synchronous alternator coaxially with the crankshaft of the power machine, the rotation of the power machine can be used to drive the rotor of the generator. Using the principle of'electromagnetic induction', the generator will output induced electromotive force, which can be generated through the closed load circuit. current.
