Automobile generators are the main power supply for cars. The function is to supply power to all electrical equipment and charge the battery when the engine is operating normally. Introduction With the advancement of automotive technology, the electricity consumption of cars is getting higher and higher. 20 years ago, the generator output power of intermediate cars was generally only about 500 watts of automobile generators, and now the generators of intermediate cars are generally around 1,000 watts. The increase in generator power increases with the increase in electrical equipment used in the vehicle. Nowadays, generators on cars are air-cooled generators, which are blown into the case by the fan behind the pulleys for cooling. Under the limitations of existing air-cooled power generation mechanisms, the increase in power will inevitably lead to an increase in the generator volume. Functional generators are the main power supply for cars. The function is to supply power to all electrical equipment and charge the battery while the engine is operating normally. Classification of automotive generators can be divided into DC generators and

Some friends reported that the power of the diesel generator set will decrease after working for a period of time. What's going on? Haixing tells you that this has a certain relationship with the environment and climate of the generator set used, and Haixing technicians will give an answer below. copyright by: www.hxdlkj.com/copyright by: www.hxdlkj.com/ From the working process of the diesel engine, it has been known that diesel is injected into the cylinder and mixed with hot air and ignites and burns, resulting in power. Therefore, the horsepower of a diesel engine is naturally related to the amount of air and the amount of diesel that can be burned. In places with high altitudes, due to the decrease in atmospheric pressure, the air density decreases, and the weight of the air inhaled into the cylinder also decreases accordingly, which limits the amount of diesel 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,

For enterprise network promotion, most of them use search engine bidding rankings, or large B2B website members (such as Alibaba), so they ignore the application of industry websites, what companies need, expand sales staff, improve corporate awareness, etc. Although industry websites are a small module, they still play an important role in your industry. Corporate network marketing is a very broad definition. Of course, the application of industry websites is a small aspect, but we also need to use it. The following mainly introduces a few applications of industry websites. 1. Choose a few suitable industry websites. A company has a budget for its promotion and costs every year, and its corporate resources are limited, and there are a large number of industry websites. Of course, it is impossible for our company to do it every company, and even if we have money, we cannot do it that way. At this time, you should choose a few suitable ones. What is appropriate? Regarding online marketing, we have always emphasized the connection, so we are choosing the website

1. Purpose and conditions of use 1. The unit operates continuously for 12 hours at rated power (including 10% overload for 1 hour). When the calibration power is backup power, the unit can only operate continuously for 1 hour at full load and has no overload capacity. 2. The unit is only suitable for use indoors or in situations where it can avoid sun and rain. 2. Introduction to the unit structure The unit consists of a diesel engine, generator, control box, voltage regulator, heat dissipation water tank, coupling and public chassis. All components of the unit are installed on a common chassis to facilitate the movement and installation of the unit. 'Four protection type, self-starting type' unit has a LCD module controlled by a microcomputer. It can automatically measure the operating parameters of the diesel engine speed, water temperature, oil temperature and oil pressure and display it with digital display. It can also be used as a fault protection device for the diesel engine. When the parameters exceed the limit, it can emit an acoustic and light alarm signal, and when the parameters exceed the limit to the extreme value, it can automatically stop emergency.

The friction side effect surface of the main moving parts of the gas generator set engine is lubricated by pressure and splashing. The composition of its circulating oil circuit is as follows: In the actual system oil circuit, only one of them is used. The pressure lubricating oil is provided by a geared oil pump, and after rough filtering and cooling, it enters the friction pairs of each moving part for lubrication. When the splashing lubricant rotates against the crankshaft, the lubricant leaked from the connecting rod bearings will splash to achieve the purpose of lubrication. The lubricating oil circuit of the gas generator set engine has slightly different design and layout depending on the model and purpose. The lubricating oil circuit of the engine has two arrangements:

(1) Coal Mine Technology Research Gas Generator Group Coal Mine Gas Generator Group is composed of a 12V190 gas engine and generator. The main components of the gas engine are developed and developed based on the 12V190 diesel engine used in raw petroleum mining farm machinery, and are also drawn from other gas engine technologies successfully developed by Ding Company in the early stage. The key innovations of the project are: the use of electronically controlled hybrid technology, gas and air mixing and then boosting technology, pre-combustion chamber technology and full electronic control technology. According to the characteristics of flammable and explosive gas in coal mines, from a safety perspective, gas fire arresters are adopted. The failure of the unit itself threatens the gas extraction and discharge system of the entire coal mine. (II) Research on gas conveying technology for coal mines with a methane concentration of 25%, according to coal mine safety production regulations, gas conveying dry and water sealed fire arrester technology is adopted and combined with fine water mist conveying technology. Low

1. What are the conditions for paralleling two generator sets? What are the conditions for paralleling the machine? Answer: The conditions for paralleling the machine are the same voltage, frequency and phase of the two generators at the moment. Generator sets are commonly known as 'three simultaneous'. It is generally recommended to use a dedicated parallel machine device to complete the parallel machine work. It is generally recommended to use a fully automatic parallel machine. Try not to manually parallel machine. Since the success or failure of manual parallel machine depends on human experience. The author boldly stated with more than 20 years of experience in power work, the reliable success rate of manual parallel machine of diesel generator is 0. The concept of manual convergence of the power supply system of the mains power system must not be used to apply a small power system, because the protection levels of the two are completely different. 2. What are the reasons for the high water temperature alarm and shutdown even if it is unable to use? Answer: Water tank leaks or insufficient water volume; water temperature sensor is damaged; water tank water channel dirt is too thick or too much oil stain; fan belt is worn too much, pressure is insufficient; water pump is worn, insufficient pump water volume is insufficient;

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. Daily technical maintenance. 2. Technical maintenance after working for 125 hours. 3. Technical maintenance after working 500 hours. 4. Technical maintenance after working for 1000 hours. (I) Daily technical maintenance 1. Check whether each instrument is normal. 2. Check the oil level of the oil pan and oil injection pump. 3. Check the amount of oil in the fuel tank and check whether there is any accumulation of scale and moisture in the precipitation cup. It needs to be disassembled clearly. 4. Remove dust adhered to the air filter element, cavity channels, etc. 5. Check for possible water leakage, oil leakage, and air leakage. 6. Check whether the connections in various parts of the diesel engine are firm. 7. Sweep the mud on the surface and keep the diesel engine, especially electrical equipment clean. If you rinse with water, be careful not to let the water enter the diesel from the gear cover ventilation port, dipstick seat hole, and air intake pipe hole.
