How to maintain the gasoline generator?
Time : 2019/11/20 15:09:25 Hits : 182
What are the precautions for opening and closing the damper of the oil generator?
Because the engine starts and closes the damper when the engine is cold, the air entering the carburetor is reduced and the concentration of the mixed gas is increased. At this time, the engine is easier to start. If the cooler opens the damper at this time, the mixed gas is likely to be adsorbed on the wall of the air intake duct, resulting in poor atomization, and it is not easy to start.
Because when the engine is started in the hot engine, the damper is opened, so that the proportion of the mixture entering the combustion chamber is normal, and the engine can be easily started. When the damper is closed, the air entering the carburetor is reduced, and the concentration of the mixed gas is greatly increased, which will make it difficult to start.

2. How to keep it when it is not used for a long time (more than three months)?
1.Drain the gasoline in the fuel tank and carburetor;
2.Drain the oil in the crankcase;
3.Fill new oil to the upper limit of the oil dipstick;
4. Close the choke door and pull the starter handle to the place where you feel resistance;
5. Wipe the unit clean and cover it with a cardboard box or plastic cover to prevent dust;

3. Cannot generate electricity:
1.Wiring error; check and correct according to the wiring diagram
2. The excitation winding of the main generator or the exciter is connected incorrectly, resulting in incorrect polarity; it often occurs when the wiring is incorrect after replacing the excitation winding. Should be checked and corrected;
3. The rotating silicon rectifier element is short-circuited, and both forward and reverse are turned on; use a multimeter to check the forward and reverse resistance of the rectifier element and replace the damaged component;
4. The main generator excitation winding is disconnected. Use a multimeter to check and measure the excitation winding of the main generator. The resistance is infinite, and the excitation line should be connected;
5. There is a serious short circuit in the windings of the main generator or the exciter; the armature winding is short-circuited, and generally there is obvious overheating. Replace damaged windings;

Fourth, the no-load voltage is too low (for example: the line voltage is only about 100 volts):
1. The exciter's field winding is broken; check that the exciter's field winding resistance should be infinite. Replace the broken coil or connect the coil circuit;
2. The exciter winding of the main generator is severely short-circuited; the exciter exciter winding has a large current. The excitation winding of the main generator is seriously heated, and the vibration is increased, and the branch current resistance of the excitation winding is much smaller than the normal value. Replace the short-circuit coil;
3. The automatic voltage regulator is malfunctioning. ; At the rated speed, measure whether the output branch current value of the automatic voltage regulator is equal to the factory no-load characteristic of the motor. Overhaul the automatic voltage regulator.
