I have a few suggestions:
1. When using batteries, you must ensure that the electrical stakes and wire connectors are firmly connected and in good contact. In winter, install an insulation device. on the battery to prevent the temperature from being too low. At the same time, increase the resistance and adjust the specific gravity of the electrolyte as necessary to keep the battery in a fully charged state to prevent the specific gravity of the electrolyte from being damaged by the battery.
2. When using the battery, water evaporation and water electrolysis during charging will cause the liquid level to drop. Therefore, the fluid level should be checked every 5-6 days in summer and daily. 10 to 15 days in winter at height and add distilled water as needed. Except for the drop in fluid level caused by a leak, no electrolytes should be added.added, otherwise battery life will be shortened. The battery fluid level should be 15mm higher than the electrode plate. If the fluid level is too high, it may overflow and corrode surrounding parts. It can also cause conduction of the positive and negative poles, causing self-discharge. The liquid level is too low, the upper part of the electrode plate will be easily exposed. Not only will the battery capacity be reduced, but the exposed plates will be quickly vulcanized.
3. When adding liquid, do not allow other substances to fall into the battery. If substances fall inside, do not use metal objects to collect them. Use dry wooden sticks to remove impurities, such as. like iron wire or copper wire. After removing the hook, the metal molecules will enter the battery under acid corrosionhydrophobic and will form a self-discharge, damaging the battery.
4. During normal driving, you should always check whether the small hole on the battery cover is ventilated. If the small hole on the battery cover is blocked, the hydrogen and oxygen generated cannot be discharged. the electrolyte expands, the battery shell will be stretched and broken.
5. For cars that have not been used for a long time, you should start the car every 25 days or so and run it at medium speed for about 20 minutes, otherwise the car will not start. when you are waiting for the car to be used.

The correct method and precautions of using water in diesel generators
Since the external ambient temperature of the diesel generator set is too low, the cooling water needs to be drainedeated after 15 minutes of stopping when the water temperature has dropped, but not immediately, otherwise the temperature difference between the fuselage and the outside. The environment will be too big. This will cause some parts of the diesel generator set to be deformed, thereby affecting 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 hinder the normal flow of 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 nott still not smooth, use hard and thin steel objects such as iron 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, thus preventing the water plug on the cylinder head from being frozen and the cooling water flowing into the oil pan in the future. mobile phoneIt should also be noted that if the water drain switch is not removed, the water drain switch should be opened after the water drain is completed, to avoid water Remaining cooling water cannot temporarily flow for various reasons and causing unnecessary freezing of the corresponding parts of the diesel engine. Loss.
Confirmation and repair of leaksof the radiator:
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 point, scrape the new metal layer with a scraper, then heat it appropriately. Once the soldering iron is heated, immerse it in the oxide solutionzinc, 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. If the leak in the upper and lower water chambers is small, you can repair it directly with solder. If the leak is large, use a purple steel sheet. to repair it. 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 diesel generator set
The water tank of the diesel generator set plays an important role in the whole body of the generator set. Bad useIoning 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 aggravate the wear of the water pump impeller andother 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 load of theengine must first be removed, then idle at low speed. When the water temperature is normal, then 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 directly at the water tank and look down. Quickly remove your hands after unscrewing it. When there is no heat orsteam, 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 on the market currently varies and many of them are of poor quality. If the antifreeze does not contain preservatives, it will seriously corrode the engine cylinder head, water jacket, radiator, water blocking ring, rubber partsc 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. Therefore, be sure to choose 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 antifreeze in time to reduce corrosion
Whether it is regular antifreeze or long-life antifreeze, when the temperaturebecomes 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 cooling water is very old. If the cooling water is dirty, it can block the pipes and radiator. Don't replace it easily.r 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. Maintain all drain switches at the same time, especially before winter, replace damaged switches in time, cannot be replaced by bolts, wooden sticks, rags, etc.
9. Open the water tank cover when draining water
If you do not open the water tank cover when draining water, although part of the cooled waterflow, as the The amount of water in the radiator decreases, the water tank is closed, this 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 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 does not shrink suddenly. However, the temperature inside the cylinder is still very high, shrinkage is faible 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 causing water leakage.
The principle of a motorcycle generator is not particular, it is just a magnetto general. The rotor with the coil rotates in the magnetic field of the stator and the magnetic lines of force are cut to generate current. The generated current goes through rectification, voltage stabilization, and then to the battery or other power-consuming components. Generally speaking, the battery can be charged normally when the motorcycle's engine speed is close to 1000 rpm. Most current batteries are maintenance-free batteries that do not require adding water. If they are traditional lead-acid batteries, they should be checked frequently and distilled water or light sulfuric acid should be filled in time. To make the motorcycle battery durable, it is best to avoid using horns, lights, etc. when the engine is not running, and always leave the engine running at high RPM for a period of time when the motorcycle is not in use for a period of time.mps. long time, the battery should be removed.
