Chengdu Kangfa Power Equipment specializes in the sale of diesel generator sets, and believes that if there is a gas leak, it is mainly due to the following reasons.
1. Valve leakage: do not open the compression stroke crankshaft to shake under decompression, it can hear the hissing sound at the inlet and exhaust channels. If the incoming and outgoing pipes have been removed, you can hear more clearly the cotton, the feathers on the incoming and outgoing ports can see the cotton, and the feathers are blown out of the air to prove that the valve is leaking.
2. Piston ring leakage: do not shake the crankshaft under decompression, when shaking to half of the compression stroke, after the vibration stops, the crankshaft, 5-10 minutes, will feel a lot of compressive force or compressive force. In addition, the vibration turns the crankshaft and they can hear the leak of oil in Canada, if the spark plug or injector is installed in the cylinder to a small hole in the oil, then the leakage sound will decrease or disappear, and the significant increase in compression force proves the piston ring leakage.
3. Air filter leakage: Check the leakage fabric of the air filter and intake manifold when the first block available enters the trachea ****, see if it is inside the 3-5 flame engine (the engine is operating at low speed), if not, then please pay attention to the air filter leakage.
4. Injector installation hole leakage: Injector installation hole, such as spark plug and preheating screw plug leakage, the location of the leakage will appear soot, and the sound will leak when the leakage phenomenon is serious.

Please ask the question to be more scientific, the diesel generator set is two parts, one is the diesel engine, and the other is the generator (DC AC). The engine powers the generator, which causes the generator wire to cut the magnetic field lines to produce electricity. Generally speaking, there is no problem of air leakage in the generator part, and air leakage should be the diesel engine, the main reason for the leakage of the diesel engine
1.When replacing the high-pressure fuel injector, the sealing copper gasket on the fuel injector is forgotten and not installed and can not play a sealing role to leak air, 2When the high-pressure fuel injector is assembled, the two fixing screws are tied unevenly, so that the sealing ring is deformed and does not seal, resulting in air leakage.
The above two solutions: use the new copper washer supplied with the new high-pressure fuel injector to load it, and tighten the two fixing screws evenly.
3.The air ring or oil ring on the piston is worn too much and leaks, the air ring or oil ring is broken, and the cylinder wall is seriously scratched and leaked, and the cylinder wall has been seriously worn and deformed, so that the gap between the piston ring and the cylinder wall is too large and leaks. Workaround:
If the piston ring is worn, replace it with a new piston ring of the same model. If the piston ring is broken and the cylinder wall is seriously scratched or the cylinder wall is seriously worn and deformed, in addition to replacing the piston ring, the cylinder needs to be respirated if necessary.
4.Cylinder bed quilt"Rush"and damage air leakage. The main reasons for this are:
The water tank is not filled with water when it is turned on; The water in the tank has leaked; The fan belt was broken and the water pump was damaged; The thermostat is damaged and does not open and is blocked, in short, the engine has no cooling water, so that the engine temperature is too high, and the high temperature and high pressure in the cylinder"Rush"Destroyed cylinder bed leakage. Solution: Remove the cylinder head; rocker arm; ejector rod; Cylinder; Cylinder bed, replace the cylinder bed with the same model and specification, tighten the cylinder screws diagonally, restore the push rod, install the rocker arm, adjust the valve clearance and then test the machine, before the test must repair or replace the damaged parts, otherwise, the cylinder head will be damaged again.
During the test run, it should be noted that the maximum water temperature should not exceed 90 degrees, and once it exceeds 90 degrees, it should be stopped immediately to check the reason.
Once a diesel engine leaks, the work efficiency will decrease and the consumption of diesel fuel will increase. It's worth noting.

Summary. Precautions for high-speed driving: emergency lane driving. Whenever there is a traffic jam, there are always some cars that drive to the emergency lane, and finally the emergency lane is also blocked. You are not allowed to enter the emergency lane during normal driving, otherwise you will be deducted points.
Hello, I am happy to answer your questions, after inquiry, the diesel engine is slightly leaking, which is completely unusable. It is important that you are aware of the defect. At present, influenza A should take protective measures when going out. I wish you a happy life.
In addition, please pay attention to the following during the return peak of the May Day holiday.
Precautions for high-speed driving: emergency lane driving. Whenever there is a traffic jam that collapses and seeps, there are always some cars that drive to the emergency lane, and finally the emergency lane is also blocked. It is not allowed to enter the spine of the emergency lane during normal driving, otherwise you will be deducted points.
Forced plugging. I believe that all car owners have experienced being plugged, and it is bad for this kind of behavior. It is recommended that all car owners send the driving records of the hungry chabo without a big jam to the online violation platform, and there will be corresponding rewards for success.
Reversing and changing heads. Many friends who run at high speed have encountered the situation of missing the exit due to the noisy slippery hole, and the correct way to do this is to continue to drive in front of the bump instead of reversing backwards. Reversing at high speed is very dangerous, and your driver's license will be deactivated.
Changing the lights with the car and the waiter. It is possible to turn on the high beams at night on the highway road to make noise, but switch to low beams when the distance from the vehicle in front is less than 150 meters.
Drowsy driving. High-speed driving should be rested every two hours of front collapse, and the longest non-silver closure should be driven for four consecutive hours. Long-distance driving is easy to slow down people's reactions, and you must know that if the braking reaction is slow for one second, the car can run 200 meters more, which is enough to lose life.

Hello dear, the diesel engine should not continue to be used if it has a slight air leak. If it is found that there is oil leakage in the diesel engine, it should be stopped immediately for inspection and maintenance to avoid further damage to the machine and cause greater losses of the lead stove. Oil leaks can be caused by a variety of reasons, ranging from aging, damaged, or loose seals to damaged or worn diesel engine parts.
Therefore, it is necessary to find the cause of oil leakage and carry out appropriate maintenance and replacement to ensure the normal operation of the diesel engine.
-
Summary. Dear, air leakage under the diesel engine may cause the machine to run unstable, or even fail to start normally. If the air leak is minor, the diesel engine can still operate normally, but this may accelerate the wear and tear of the machine and affect the life of the machine.
Therefore, if you find that the diesel engine has an air leak, it is recommended to find the cause of the air leak as soon as possible and repair and replace it. Some common causes of under-air leakage include aging gaskets, loose screws, worn oil seals, etc. If you do not know how to repair and replace the relevant parts, it is recommended to consult a professional technician or service center to avoid further damage to the machine due to improper operation.

If the air leak is slight, the diesel engine can still operate normally, but this may accelerate the wear and tear of the machine and affect the life of the machine. Therefore, if you find that the diesel engine has air leakage, it is recommended to find the cause of the air leak as soon as possible and repair and replace it.
Some common causes of under-air leakage include aging gaskets, loose screws, worn oil seals, etc. If you do not know how to repair and replace the relevant parts, it is recommended to consult a professional technician or service center to avoid further damage to the machine due to improper operation.
I'm talking about whether a slight air leak lasts 3-4 months.
Dear, it can be used, but if your diesel engine has been leaking for 3 to 4 months, it is recommended that you find the cause of the leak as soon as possible and repair and replace it. Prolonged air leakage will lead to increased wear and tear of the machine, affect the life of the machine, and also increase the safety risk of use. Some common causes of air leakage include aging of gaskets, loosening of screws, and wear of oil seals.
If you do not know how to repair and replace the relevant parts, it is recommended to consult a professional technician or service center to avoid further damage to the machine due to improper operation. Before repairing and replacing, it is recommended that you suspend the use of diesel engines to avoid more serious failures.

Why does the diesel power generation BAI unit drip oil during operation? The piston-cylinder liner is not well sealed, the oil plate is channeled, enters the combustion chamber for combustion, and the exhaust gas emits blue smoke.
For supercharged diesel engines, due to low load, no load, low boost pressure. It is easy to cause the sealing effect of the oil seal in the supercharger to decrease, and the oil will enter the pressurized chamber and enter the cylinder with the intake air.
A part of the oil that goes up to the cylinder participates in combustion, and a part of the oil cannot be completely burned, forming carbon deposits in the valves, intake tracts, piston tops, piston rings, etc., and some of them are discharged with the exhaust, so that the oil will gradually accumulate in the exhaust tract of the cylinder liner and carbon deposits will also be formed.
Oil in the booster chamber of the supercharger accumulates to a certain extent and leaks out of the joint surface of the supercharger.
Long-term small operation will lead to more serious consequences such as increased wear of moving parts and deterioration of the combustion environment of the engine, which leads to the early overhaul period.

Hello! If BAI is leaking oil, one is the valve du
The oil seal is not well sealed, and the oil will be discharged from the exhaust pipe. Return.
The second is the oil leakage of the supercharger. If the answer is that the diesel fuel is leaking, it means that the fuel injector is stuck and the atomization is not good, resulting in incomplete combustion, and then it is discharged from the exhaust pipe.

There is no such statement.
The purpose of heat preservation of the exhaust pipe is to prevent the heat of the exhaust pipe from being released in the machine room and increase the temperature of the machine room.

The dripping oil in the exhaust pipe of the diesel generator set is mainly caused by the long-term small load operation of the diesel generator set.
Because there are many places in the diesel generator in the form of pressure seals, such as cylinder liner - piston - piston ring, supercharger - supercharger rotor shaft, this seal is generally in the engine has about 1 3 load, only to play a full role, and the load hour may occur slight leakage.
Therefore, users must pay attention to the correct use of the unit in the process of using the diesel generator set, and cannot let the unit run with a small load for a long time, so as not to cause the unit failure.

If the valve mechanism of the diesel generator is worn or the screws are loose. We need to carry out repairs in a timely manner. The maintenance methods include cylinder-by-cylinder adjustment method, two-turn adjustment method, etc. Let's first introduce the most commonly used cylinder-by-cylinder adjustment method:
Rotate the flywheel according to the working steering of the crankshaft, pay attention to observe the push rod of the sixth cylinder intake and exhaust valve close to the flywheel, when it is found that the two push rods move up and down at the same time, it means that the sixth cylinder of the diesel generator set is in the state of the overlapping angle of the intake and exhaust valves, and stops the transfer. At this time, the piston of the first cylinder is in the process of compressing the stroke, and the intake and exhaust valves are closed. You can use the feeler gauge to check and adjust the clearance of the intake and exhaust valves of the first cylinder.
There are two other ways to determine the closed state of the valve:
1. Through the straight groove observation hole on the pump body of the high-pressure fuel injection pump, it can be observed that the plunger or lead cylinder of the oil pump is in the process of tasting the arc and stirring some saturation of the old fat, and the cylinder valve corresponding to the oil pump is in a closed state.
2. The door can be opened to check that the top column roller falls on the cam base circle, and the air valve is in a closed state.

Household diesel generators.
Power generation cannot be connected to the grid. Because private power generation equipment needs to apply to the relevant departments if it wants to be connected to the grid, the power supply company will send someone to test and check whether it meets the grid connection requirements.

Generators are also known as synchronous generators, and the power systems of China and a bunch of countries led by the former Soviet Union are all 50Hz frequency, and 60Hz in Western countries. When you say 1500 rpm, you mean a generator with 2 pairs of poles. The 1500 rpm motor you are talking about is also a synchronous motor, if it is an asynchronous motor, the speed should be about 1480, there is a slip rate, and the asynchronous motor is divided into squirrel cage type (such as Y series) and winding type (such as ZR series). >>>More
