How to deal with water entering the mobile generator
Although hydrogen enters the generator through the dryer, there will bealways a certain amount of humidity, so the generator is mandatory The temperature of the cold water used must be higher than the temperature of the hydrogen, otherwise the hydrogen will condense when it is cold, because the water does not is not allowed in the generator.
Generators are mechanical devices that convert other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other electrical machines to convert water flow, air flow. , fuel combustion or atomic nuclei The energy produced by fission is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.
What should I do if water leaks from the tankof water from the diesel generator when the water flows out of the body?
1. When it turns out that water has entered the generator, close it. immediately turn off the generator if it is running. Allow startup.
2. Support one side of the mobile generator set with a hard object and lift it so that the oil drain part of the engine oil pan is in the lowest position, unscrew the oil drain plug, remove it. oil dipstick, and the water inside drains out by itself. When the oil is about to drain, let the oil and water drain for a while, then tighten the oil drain plug.
3. Remove the air filter, replace the new filter element and soak it in oil.
4. Remove the intake and exhaust pipes and muffler, and remove any water from the pipes. Turn on the decompression, start the diesel engine to produce electricitycited and observe if water flows from the inlet and exhaust ports. If there is water drained, continue to rotate the crankshaft until all the water in the cylinder is drained. Install the intake and exhaust pipes and mufflers, add a little engine oil to the air inlet, crank the crankshaft a few times, then install the air filter.
5. Remove the fuel tank, drain all oil and water from it, check for water in the fuel system and drain it.
6. Release the waste water into the water tank and water channels, clean the water channels and add clean river water or boiled well water until the water float mounted. Turn on the throttle switch and start the diesel engine. After starting the diesel engine, pay attention to the engine oil indicator rising and listen for any abnormal noise coming from the diesel engine. After checkingIf all parts are normal, run the diesel engine. The operating sequence is first at idle, then medium speed, then high speed. The running time is 5 minutes each. After break-in, stop the engine and drain the engine oil. Fill with new oil, start the diesel engine and run it at medium speed for 5 minutes, then it can be used normally.
7. Disassemble the generator, check the stator and rotor inside the generator, then dry them before assembly.
Users of mobile generator sets should pay attention to protecting the unit after the unit is wet and in humid environments, to ensure the normal operation of the generator set.

The correct method and precautions for using water in diesel generators
Since the external ambient temperature of the diesel generator set is too low, the cooling water should be drained after 15 minutes of shutdown when the water temperature has dropped, but not immediately, otherwise the temperature difference between the fuselage and the external environment will increase. too large, causing the diesel generator set to malfunction. Some parts of the engine are deformed, which in turn affects the performance of the diesel engine (such as cylinder head deformation, etc.).
When draining water, you can't turn on the water release switch and everything will be fine. You also need to pay attention to the specific water flow conditions to see if the water flow is smooth and the water is good. the flow becomes smaller or faster and slower. If these conditions occur, it means that the cooling water contains impurities that impede the normal flow of the water.'water. At this point, it is best to remove the water drain switch and let the cooling water flow directly from the body. If the water flow is still not smooth, use hard, thin steel objects such as wire to dredge it until the water flow is smooth.
When the cooling water stops flowing, it is best to shake the diesel generator several times. At that time, the remaining cooling water that is not easy to flow will flow out because of the cooling water. vibration of the diesel engine, thereby preventing the water plug on the cylinder head from being frozen and the cooling water flowing into the oil pan in the future. The operator should also note that if the water drain switch is not removed, the water drain switch must be in the open state after water draining is completed to avoid the remaining cooling water cannottemporarily flow for various reasons and it freezes. the corresponding parts of the diesel engine.
Confirmation and repair of radiator leaks:
1. Block the inlet and outlet of the radiator, install a gasket from the overflow pipe or drain plug and drive 0.15 to 0.3 kgf/cm² of compressed air. Place the heater in the pool. If there are bubbles, it's a leak.
2. Check with water. When inspecting, block the water inlet and outlet of the radiator. After filling the inlet with water, observe for water leaks. To make it easier to discover small cracks, you can apply some pressure to the radiator or vibrate the radiator. lightly, then observe carefully, water flows from the leak. Radiator Welding Repair Radiator welding repair generally uses the brazing method. Before welding, wipe off the oil at the welding place, then useUse a scraper to scrape off the new metal layer, then heat it appropriately. Once the soldering iron is heated, dip it into the zinc oxide solution, then apply solder. After bonding, smooth the solder and use hot water to clean the zinc oxide around the solder to avoid corrosion.
3. Welding repair of upper and lower water chambers. When the leak in the upper and lower water chambers is not large, you can directly use solder to repair it. Repair with purple steel skin. When repairing by welding, first apply a layer of solder to one side of the steel skin and the leak area, place the steel skin on the leak area, and then use a soldering iron to heat the outside in order to melt the solder and weld the surrounding area. firmly.
The correct use of the water tank of the electro groupdiesel gene
The water tank of the diesel generator set plays an important role in the whole body of the generator set. Improper use of water tanks will damage the diesel engine and generator and in severe cases may result in scrapping of the diesel engine. So it is very important to use the water tank of the diesel generator correctly.
1: Choose clean, soft water
Soft water generally includes rainwater, snow water, river water, etc. This water contains few minerals and is suitable for engine use. Well water, spring water and tap water contain high mineral content. These minerals are easily deposited on the water tank wall, water jacket and water channel wall when heated to form scale and rust, which deteriorates the heat dissipation ability of the motor and easily causes the motor. overheat.The added water must be clean. Impurities in the water will block the water channels and worsen the wear of the water pump impeller and other components. If hard water is used, it must be softened first. Softening methods typically include heating and adding lye (usually caustic soda).
2. Do not start the machine first and then add water.
Some users, in order to facilitate starting in winter, or because the water source is far away, often adopt this method. start the machine first and then add water. This method is very harmful. After the engine is started dry, because there is no cooling water in the body, the engine parts heat up quickly, especially the cylinder head and the water jacket outside the injector of the diesel motor. If cooling water is added at this time, the cylinder head. and the water shirt will do it. It is easy to crack or deform due to sudden cooling. When the engine temperature is too high, the engine load should first be removed and then idle at low speed. When the water temperature is normal, add cooling water.
3. When "opening the pot", avoid burns.
After the water tank is "boiled", do not blindly open the water tank cover to avoid burns. The correct approach is: first let the engine idle for a while, then turn off the generator. Wait for the generator temperature to drop and the pressure in the water tank to drop before unscrewing the water tank cover. When unscrewing, cover the lid with a towel or car rag to prevent hot water and steam from being splashed on your face and body. Never point your head directlytowards the water tank and look down. Quickly remove your hands after unscrewing it. When there is no heat or steam, remove the water tank cover to avoid burns.
4. Water heating in winter
In cold winter, it is difficult to start the generator if you add cold water before starting, it will easily not start in time during or. after adding water. When the water tank drain chamber and water inlet pipe are likely to freeze, water cannot flow and the water tank may even burst. Adding hot water can, on the one hand, increase the engine temperature to make starting easier, on the other hand, it can try to avoid the freezing phenomenon mentioned above.
5. Antifreeze must be of high quality
The quality of antifreezes currently on the market varies and many of them are of poor quality. If the antifreeze does not contain conservatives, it will seriously corrode the engine cylinder head, water jacket, radiator, water blocking ring, rubber parts and other components. At the same time, a large amount of scale will be produced, resulting in poor quality. heat dissipation of the motor and cause motor overheating. So you have to chooseUse products from regular manufacturers.
6. Refill the fresh water in time
After filling the water tank with antifreeze, if you find that the liquid level in the water tank has dropped, you only need to add clean fresh water. water assuming no leaks (distilled water is better), because the boiling point of commonly used ethylene glycol antifreeze is high and this evaporates, it is the water contained in the antifreeze. but only fresh water. It’s worth mentioning: never add unsoftened hard water.
7. Drain the antifreezel in time to reduce corrosion
Whether it is ordinary antifreeze or long-life antifreeze, when the temperature becomes high, it should be released in time, so as to prevent Increase corrosion of mechanical parts. Because the preservatives added to antifreeze will gradually decrease or become invalid as the use time increases, and even worse, some simply do not add preservatives, which will have a strong corrosive effect on mechanical parts, so it should release the antifreeze in time according to the temperature conditions, and the cooling pipeline should be carefully cleaned after releasing the antifreeze.
8. Change the water regularly and clean the pipes.
It is not recommended to change the cooling water frequently, because after a period of use, the minerals in the cooling water have precipitate. , unless the water is very oldborn. If the cooling water is dirty, it can block the pipes and radiator. Do not replace it easily, because even though the newly replaced cooling water has been softened, it still contains some minerals. settle in the water jacket and other places to form scale. The more frequently the water is replaced, the more minerals precipitate and the thicker the scale becomes. Therefore, the cooling water should be replaced regularly according to the actual situation. The cooling pipe must be cleaned when replacing. The cleaning solution can be prepared with caustic soda, kerosene and water. At the same time, maintain each drain switch, especially before winter. Replace damaged switches in time. Do not replace them with bolts, wooden sticks, rags, etc.
9. Open the water tank cover when draining the water
If you do notDo not open the water tank cover when draining the water, although some of the cooling water may flow out, because the The amount of water in the radiator decreases, the water tank If the water is turned off, it will produce a certain degree of vacuum, which will slow or stop the flow of water. In winter, the rooms will be frozen due to the discharge of impure water.
10. It is not advisable to drain the water immediately when the temperature is high.
Before the engine stalls, if the engine temperature is very high, do not stop the engine immediately to drain the water. You must first remove the load and let it run at idle until the water temperature drops. Do not release water before it reaches 40-50°C to avoid the temperature of the outer surface of the cylinder, cylinder head and water. the shirt in contact with water does not suddenly fall off due to the sudden release of water and shrinkquote not abruptly. However, the temperature inside the cylinder is still very high, the shrinkage is small, and it is easy to cause cracks in the cylinder block and cylinder. head due to the excessive temperature difference between inside and outside.
11. Run the engine at idle speed after draining the water in cold winter.
In cold winter, after draining the cooling water from the engine, you should start the engine and let it idle for a few minutes. This is mainly due to the fact that the water pump after draining the water, moisture may remain in the machine parts. After restarting, the body temperature can dry the residual moisture in the water pump and other places to ensure that there is. No water in the engine. Add antifreeze in time and drain the coolant to prevent the water pump from freezing and cracks.indicate water leaks.
There are several common reasons for abnormal noise after a vehicle wades through water:
1. If the brakes make an abnormal noise while driving right after wading through water, it is due to moisture or foreign objects present in the brake disc. If there are no foreign objects, the abnormal noise will disappear as the water dries;
2. After wading for a while and driving, the chassis makes an abnormal noise and the cause of the abnormal tire noise. was eliminated. It is very common for the vehicle's bearings to make an abnormal noise due to lack of lubrication after floundering for a while, if the gearbox makes an abnormal noise when idling or while driving; to water entering the transmission. Insufficient lubrication behind the gearbox causes abnormal noise in the internal bearings;
4. After wading for un some time, if there is an abnormal noise from the front of the engine while idling or when driving, it is due to water entering the generator belt tensioner. Insufficient lubrication can occur due to insufficient lubrication of the internal bearings of the compressor or generator.
