Causes of abnormal noise in generator: ①Generator V-belt slips. ②The generator bearing is damaged. ③ Friction occurs between the rotor and the stator. ④The fan blade collides with the front cover. 1. If abnormal noise occurs intermittently and is severe when the generator speed changes, the deflection of the generator V-belt should be checked and adjusted. 2. If the abnormal noise persists, check if there is friction between the fan blades and the front cover.
What is the reason for the abnormal generator noise?
The reasons for the abnormal noise of the generator: ① The V-belt of the generator slips. ②The generator bearing is damaged. ③ Friction occurs between the rotor and the stator. ④The fan blade collides with the front cover.
1. If abnormal noise occurs intermittently and is severe when the generator speed changesge, the deflection of the generator V-belt should be checked and adjusted. 2. If the abnormal noise persists, check if there is friction between the fan blades and the front cover. Use a stethoscope to listen carefully to the front, middle, and back of the generator. If there is significant noise from the front and rear of the generator, the generator bearings are damaged or poorly lubricated; if the noise is in the middle of the generator and there is a feeling of vibration, it is the friction between the rotor and the rotor; stator. The generator must be disassembled and the corresponding parts must be lubricated or replaced. 3. Abnormal noise occurs when the generator turns once. The fault often occurs in crankshaft related parts, such as pistons, piston pins, piston rings, connecting rod bearings, etc. 4. Abnormal noises continue to appear, and there is some regularity in theabnormal noises. Defective parts mainly appear on rotating parts. For example, continuous knocking noises often appear on parts such as flywheels and timing gears. 5. Abnormal sounds appear intermittently and the noise is irregular. The main cause of the failure is that the generator accessories, such as generator, water pump, air compressor, starter, etc., are installed loosely. , or scrape the inside, etc.
Why is the generator making an abnormal noise?
Abnormal engine noise can be regarded as abnormal engine noise. Sometimes after changing the oil, to be precise, after changing high viscosity oil, you can clearly hear abnormal noises coming from the engine. This abnormal noise is mainly caused by high viscosity and large internal resistance. .What an impact.
However, itThere is a problem with the hydraulic lifter, which often makes a “clicking” sound. The application of hydraulic lifters is to automatically eliminate valve clearance and reduce engine noise. However, once the hydraulic lifter fails, it will cause a serious "clicking" sound in the engine. Sharp knocking noise: The so-called sharp knocking noise, such as a knocking triangle or a click, is mainly due to the engine knocking or knocking noise. Engine knocking is a common occurrence and is not necessarily a fault. This may also indicate that the engine is in poor condition. However, cylinder knocking is mainly caused by faults. Possible reasons for engine cylinder knocking include: advanced ignition angle, premature ignition leads to abnormal piston pressure and causes cylinder knocking. At this time, the ignition angle needs to be adjusted or piston deformation;The cylinder is deformed or pulled; the gap between the piston and the cylinder is too large; inferior engine oil does not cause protective lubricating oil film on machine parts, carbon or sludge deposits inside the engine are extremely serious, etc. We know the engine knock. If the ignition advance angle or compression ratio of the engine is high and the octane rating of the added fuel is too low, the engine will knock easily. Whether it is knocking or tapping on the cylinder, in addition to abnormal knocking noises, this is often accompanied by engine shaking. Abnormal engine noise: Actually, it is better to find the cause of this kind of abnormal engine noise, because abnormal engine noise is mainly caused by the aging of different sets of belts in the engine, or tightening problem wheels, resulting in loose belts. , rubabnormal movements and noises, belt slippage, etc. If there is a "grinding" noise, look for major belt assemblies and tensioners inside the engine, such as engine timing belts, generator belts, circulating water pump belts, air belts, booster pump belts, etc. What causes abnormal generator noise?

The generator will generate a lot of heat when it is running to produce electricity. pass between the stator and the rotor, so the generator There will be fan blades at one end. The high-speed fan blades should blow the cooling air. There should be a grid-like net (mostly circular and closed) on the outside. which is the windshield of the generator, which acts as protection against the bladesof the fan. Protection against falling objects on the fan blades.
