1. Before starting, check whether the fuel tank is sufficient, and there is no oil leakage at the oil pipes and joints; whether the cooling system is sufficient, clean and free of leakage, and whether the fan belt is tight. 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.

2. After starting, it should run at low speed for 3~5 minutes, and the operation can be started only after the temperature and oil pressure wheel are normal. The generator shall be free of abnormal noise during speed-up, and the brushes on the slip ring and commutator shall be in good contact, without jumping and sparks. After the operation is stable and the frequency and voltage reach the rated value, the power can be supplied to the outside.

3. In case of abnormal noise, peculiar smell, sharp rise in water temperature and sharp drop in oil pressure during operation, stop the machine immediately for inspection and troubleshooting.

4. The generator power factor shall not exceed the late phase (lag) 0.95. The variation range of the frequency value shall not exceed 0.5HZ.

5. Before stopping, cut off the main switch of each power supply shunt, gradually reduce the load, then cut off the main switch of generator power supply, return the excitation rheostat to the maximum resistance position, reduce the voltage to the lowest value, then cut off the excitation switch and neutral grounding switch, and finally stop the operation of the internal combustion engine.

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.

Car fuel injector oil leakage will cause the engine to idle?

Oil leakage from the fuel injector of a car will cause the engine to tremble at idling speed, and the gasoline dripping into the cylinder will make the mixture too rich, and the mixture too rich will cause difficulty in starting the engine. If the fuel injection nozzle carbon deposition is more serious, may lead to a slight drip phenomenon. Car friends can add additives that can remove carbon deposits to the fuel tank when refueling, so that the carbon deposits on the fuel injector can be removed.
