The car generator is the main power source of the car. Its function is to supply power to all electrical equipment and charge the battery at the same time when the engine is running normally. Introduction With the advancement of automobile technology, the power consumption of automobiles is getting higher and higher. Twenty years ago, the output power of generators for mid-level cars was generally only about 500 watts. Now, the output power of generators for mid-level cars is generally around 1,000 watts. The increase in generator power increases with the increase in electrical equipment on the vehicle. Nowadays, the generators on cars are all air-cooled generators. The fan behind the pulley blows air into the casing for cooling. Under the limitations of the existing air-cooled generator structure, the increase in power will inevitably lead to an increase in the size of the generator. The functional generator is the main power source of the car. Its function is to supply power to all electrical equipment and charge the battery at the same time when the engine is running normally. Classification Automotive generators can be divided into DC generators and

Some friends have reported that the power of the diesel generator set will decrease after working for a period of time. What is going on? Haixing tells you that this has a certain relationship with the environment and climate in which the generator set is used. Haixing technicians give the answer below. copyright by：www.hxdlkj.com/copyright by：www.hxdlkj.com/ It is known from the working process of diesel engine that diesel is injected into the cylinder and mixed with hot air and then ignites and burns to generate power. Therefore, the horsepower of a diesel engine is naturally related to the amount of air and the amount of diesel it can burn. At high altitudes, due to the decrease in atmospheric pressure, the density of the air decreases, and the weight of the air sucked into the cylinder also decreases accordingly. This limits the amount of diesel fuel that can be burned, and the horsepower decreases. For the same reason, high air temperature and high humidity will also reduce the horsepower of the diesel engine. So, whether

The friction side surfaces of the main moving parts of the gas generator engine are lubricated by pressure and splash. The composition of the circulating oil circuit is as follows: The air-cooled oil cooler and water-cooled oil cooler in the picture are in the actual system oil circuit. , only use one of them. Pressure lubricating oil is provided by a gear oil pump. After rough filtering and cooling, it enters the friction pairs of each moving part for lubrication. Splash lubricating oil achieves the purpose of lubrication by splashing the leaking lubricating oil in the connecting rod bearing when the crankshaft rotates. The lubrication oil circuit of the gas generator set engine is slightly different in the design and layout of the oil circuit due to different models and uses. The engine's lubricating oil circuit has the following two layouts:

(1) Coal Mine Technology Research Gas Generator Set The coal mine gas generator set is composed of a 12V190 gas engine and a generator. The main components of the gas engine are developed on the basis of the original 12V190 diesel engine used in petroleum mine machinery, and draw lessons from other gas engine technologies successfully developed by Ding Company in the early stages. The key innovations of this project are: the use of electronically controlled mixing technology, gas and air first mixing and then supercharging technology, pre-combustion chamber technology and fully electronic control technology.

1. What are the conditions for two generator sets to be used in parallel? What device should be used to complete the parallel operation? Answer: The conditions for parallel use are that the instantaneous voltage, frequency and phase of the two generators are the same. The generator set is commonly known as 'three simultaneous' '. Use a special paralleling device to complete the paralleling work. It is generally recommended to use a fully automatic paralleling cabinet. Try not to use manual paralleling. Because the success or failure of manual paralleling depends on human experience. The author boldly speaks out with more than 20 years of experience in electric power work, The reliable success rate of manual paralleling of diesel generators is 0. The concept that a large mains power supply system can be manually paralleled must not be applied to a small power supply system, because the protection levels of the two are completely different. 2. What are the reasons for the high water temperature alarm to shut down and make it unusable? Answer: The water tank is leaking or the water volume is insufficient; the water temperature sensor is damaged; the dirt in the water channel of the water tank is too thick or the heat sink is too oily; the fan belt is too worn and the pressure is insufficient; the water pump is worn , the pump water volume is insufficient; saving

Correct maintenance is an important guarantee to ensure the normal and reliable operation of the diesel engine and extend the service life of the diesel engine. Technical maintenance is divided into the following four categories: 1. Routine technical maintenance. 2. Technical maintenance after 125 working hours. 3. Technical maintenance after 500 working hours. 4. Technical maintenance after 1,000 working hours. (1) Daily technical maintenance 1. Check whether each instrument is normal. 2. Check the oil pan and the oil level of the fuel injection pump. 3. Check the amount of oil in the fuel tank and check whether there is scale and water in the sedimentation cup. It needs to be disassembled and cleaned. 4. Remove dust adhering to the air filter element, inner cavity channels, etc. 5. Check for possible water leaks, oil leaks, and air leaks. 6. Check whether the connections everywhere in the diesel engine are firm. 7. Clean away the mud on the surface and keep the diesel engine, especially the electrical equipment, clean. If flushing with water, be careful not to allow water to enter the diesel engine through the gear cover vent, oil dipstick seat hole, and air intake pipe hole.

Cummins generator sets use Dongfeng Cummins B and C series engines, which have advanced technology and reliable performance. They are equipped with Wuxi New Era Stanford generators that recover quickly in voltage and frequency when subjected to instantaneous loading. Coupled with the uniquely designed built-in multi-level vibration reduction system, they can effectively It eliminates vibration when the unit is running and protects the control system and electrical components; it can also provide very reliable power in extremely harsh environments. Advantages of Cummins generator sets: 1. When several Cummins generator sets are paralleled, it is equivalent to one high-power generator set supplying power to the load. You can decide how many units to operate according to the size of the load (the generator set operates at 75% of the rated load) (lowest fuel consumption), thereby achieving the purpose of saving diesel and reducing the cost of the generator set. Especially now that diesel is in short supply and oil prices are rising rapidly, saving diesel has become very important. 2.
