Introduction of generator inspection content and description of its structure
What is a generator? Presumably we all know very well. Usually during our work, we are troubled by power outages, and the existence of generators has helped us solve this problem. So what else do you do n’t know enough about it? I believe this article will inspire you. The following is the introduction of "introduction of generator inspection content and description of its structure".
[Check and adjust generator clearance]
First, the inspection of the spark plug electrode gap of natural gas generating units:
The spark plug electrode gap is generally 0.40-0.50mm. This gap is generally not adjusted. If the spark plug is not suitable for ignition, check and adjust by:
1. Remove the spark plug;
2. Carefully remove dirt such as carbon deposits between the electrodes;
3. Check and adjust the electrode gap. If the adjustment still does not work, the spark plug should be replaced.
Adjusting the ignition advance angle of natural gas generating units
The ignition advance angle of the engine has been adjusted to a suitable position before leaving the factory, and generally does not need to be adjusted. However, when the difference in gas composition is large or the engine is running for a long time due to vibration and other factors, the ignition advance angle changes and affects normal work. The angle should be adjusted.
When adjusting, loosen the signal generating plate fixing bolt, turn the signal plate clockwise to decrease the ignition advance angle; turn the signal plate counterclockwise to increase the ignition advance angle. After adjustment, tighten the fixing bolts.
The ignition advance angle can also be set by the ignition advance angle adjustment switch on the side of the ignition unit.
[Components of generator]
更换天然气发电机组封水圈。 1 The seal ring of the cylinder liner is damaged and leaks. Replace the seal ring of the natural gas generator set.
检查气缸套肩胛与机体之间的接合面是否平整。 2 Water leakage at the joint between the cylinder liner and the body of the natural gas generator set Check whether the joint between the shoulder of the cylinder liner and the body is flat.
更换新的气缸套。 3The cylinder liner leaks water due to cavitation and perforation. Replace the cylinder liner with a new one.
更换衬垫。 4 The cylinder head gasket is damaged and the gasket is leaking. Replace the gasket.
拆检天然气发电机组机油冷却器芯子或。 5 The oil cooler core of the water-cooled natural gas generator set is damaged, and the cooling water and the oil are mixed to disassemble and inspect the oil cooler core of the natural gas generator set.
天然气发电机组机体水腔壁穴蚀而漏水（特别是靠推杆测气缸壁） 对穴蚀小孔可仔细焊补或闷牢，但不能损伤配合面和变形。 6 Natural gas generating unit body water cavity wall cavitation corrosion and leakage (especially by measuring the cylinder wall with a push rod) can carefully repair or suffocate the cavitation holes, but cannot damage the mating surface and deformation. If the corrosion is serious, the body should be replaced.
Natural gas generating unit body cavity cavitation and leakage of water (especially by measuring the cylinder wall with push rod) can be welded or blocked tightly, but it cannot damage the mating surface and deformation. If the corrosion is serious, the body should be replaced.
The above introductions about "checking and adjusting the generator clearance" and "the components of the generator" hope to help you understand the "introduction of the generator inspection content and the description of the structure".
- In the power generation industry in China, we have been working hard, pursuing the concept of quality and service, and for the sake of customers, the full power generator chooses China and your generator is a professional housekeeper. At present, the diesel generator set maintenance market refers to damage inspection and routine maintenance. Two aspects: after maintenance refers to the failure of the diesel generator, there are problems with various accessories, such as replacing the generator or
- The diesel engine is working normally, but the generator fails to generate electricity or the voltage is very low. This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The rotor's dead center residual magnetism is weakened or declining. It will make the generator unable to generate electricity or the transmission voltage is extremely low. The right to respond is usually: use an appropriate DC voltage and directly connect to the excitation winding according to the polarity Magnetization. Carefully inspect the exciter and the cyclotron rectifier, find abnormal components or windings, and replace them for restoration. The generator's transmission voltage is unstable, and
- Before starting, you should check whether the fuel volume of the fuel tank is rich, and there is no oil leakage in each oil pipe and the discussion area; whether the cooling system water is rich, clean and leak-free, and whether the fan belt is tight or not. The internal combustion engine and generator drive parts should be connected and trusted. The wires of the input line are well-insulated, complete and effective in all aspects. After starting, it should run at low speed for 3 to 5 minutes. After the temperature and oil pressure wheel are normal, the initial work can be done. The generator should be no different in the speed increase. Ring, the slip ring and commutator are well brushed, no jumping and sparking phenomenon. After the operation is stable and the frequency and voltage reach the rated value, power can be supplied to the outside.
- Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the height of the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, replace the component and reduce the clearance. The normal mutual assistance clearance between the two is 0.0
