A few days ago, it was reported that a mother-in-law and daughter-in-law in a factory in Jiangyin used a small gasoline generator set for lighting and heating in the office due to a power outage after get off work. As a result, a poisoning incident occurred. After on-site inspection by the 120 emergency center ambulance personnel, it was confirmed that the two women were dead. Small generator sets usually generate electricity by burning fuel to generate power. All kinds of fuels are high in carbon content. When the generator is running, it will produce a large amount of exhaust gas containing carbon monoxide, and it will also consume a large amount of oxygen in the environment. Carbon monoxide poisoning from running generators is particularly common in developed countries.

The motor-generator unit is driven by an electric motor to rotate the synchronous motor, and adjusts the output voltage of the generator by adjusting the excitation current of the generator. The advantage of this method is that it can press evenly and accurately. It is not affected by the same voltage fluctuation. The well can supply a sinusoidal voltage transition (Figure 1).

As a technical expert in the generator set industry, Haixing Power Technology often finds that many customers ignore the adjustment of the oil supply process, which is obviously a bad habit. Therefore, Haixing Power Technology summarizes how to adjust the injection advance angle of the generator set?

Haixing Power Technology has created an encyclopedia of technical knowledge about generator sets. Many customers cannot understand the power definition of diesel generator sets. Therefore, our Haixing Power Technology Company will explain it to you. First of all, let’s understand the power standard of the generator set; the main power of the diesel generator set is also called continuous power or long-term power. In China, the main power is generally used to identify the diesel generator set, but internationally it is Standby power, also known as maximum power, is used to identify diesel generator sets. After observation, our Haixing Power Company found that irresponsible manufacturers in the market often use maximum power as continuous power to introduce and sell generator sets, resulting in Many users misunderstand these two concepts. Secondly, regarding the power of the generator set, Haixing Power Technology gave an example. Diesel generator sets in our country are rated by main power, that is, continuous power. The generator set can operate within 24 hours.

How to parallel the generator sets? What are the requirements and conditions for parallel operation? What are the advantages and disadvantages of parallel units? Haixing Power Technology analyzes parallel machine technology for our customers! Usually, the parallel operation of generator sets means that two generator sets are organically combined through a parallel system to achieve a theoretical increase in power generation. Two units running in parallel to generate electricity must meet three conditions: the same voltage, the same frequency, and the same initial phase. Theoretically, units of different types can operate in parallel to generate electricity as long as they have electronic speed control systems.

Many companies are helpless when facing the problem of cylinder failure of generator sets. Therefore, Gu Zhiqing, a technical expert from Haixing Power Technology Co., Ltd., came to solve the problem for the public.

Jiangsu Haixing Power Technology Co., Ltd. has been engaged in the generator set industry for many years and has detailed standards for the performance indicators of diesel generator sets. The performance of the generator set is what enterprises are most concerned about. Only generator sets with excellent performance can provide customers with a complete power supply system. 1. Appearance requirements (1) The boundary dimensions, installation dimensions and connection dimensions of the diesel generator set shall comply with the manufacturer's drawings approved by the prescribed procedures. We at Jiangsu Haixing Power think this is very important. If you don't think about it first, subsequent installation will become a big problem. (2) The welding of the unit should be firm, the welds should be uniform, and there should be no defects such as weld penetration, undercuts, slag inclusions, and pores. The welding slag and flux should be removed cleanly; the paint film should be uniform without obvious cracks and peeling; the coating should be smooth , no missing plating spots, rust, etc.; the fasteners of the unit should not be loose. (3) The electrical installation should comply with the circuit diagram, and the connection points of each wire of the unit should have obvious signs that are not easy to fall off. (4) There should be a well-grounded terminal

Recently, Haixing Power Technology Co., Ltd. communicated with many customers and found that the customers were very troubled by the noise generated by the generator set, so Haixing organized an article based on the customer's questions on how to deal with the noise in the generator room. Question: Where does the noise in the generator room come from? Answer: Jiangsu Haixing Power believes that diesel engine unit noise is a complex sound source composed of multiple sound sources. According to the mode of noise radiation, it can be divided into aerodynamic noise, surface radiation noise and electromagnetic noise. According to the cause of generation, diesel engine surface radiation noise can be divided into combustion noise and mechanical noise. Among them, aerodynamic noise is the main noise source. 1. Aerodynamic noise is caused by the unsteady process of gas, that is, by the disturbance of gas and the interaction between gas and objects. Aerodynamic noise radiated directly to the atmosphere, including intake noise, exhaust noise and cooling fan noise. 2. Combustion noise and mechanical noise

Haixing Power Technology reminds buyers that when purchasing a diesel generator set, they need to analyze many aspects of the unit in order to choose a satisfactory product with excellent performance and environmental suitability. As a professional manufacturer, Haixing Power Technology Co., Ltd. does not regard profit as its foundation. It has a responsible and serious attitude towards customers and helps customers choose the most suitable products. Jiangsu Haixing Power believes that the main factors that should be considered when purchasing a diesel generator set include mechanical and electrical performance, purpose of the unit, load capacity and change range, automation functions, etc. (1) Purpose. Because diesel generator sets can be used in three situations: regular use, backup and emergency. Therefore, different uses have different requirements for diesel generator sets. When purchasing a communication generator set, you must meet the requirements of G3 or G4 in GB2820-1997, as well as the 24 performance index requirements specified in the 'Implementation Rules for Network Quality Certification and Inspection of Communication Diesel Generators'.

Recently, it was reported that many elderly people in the community reported that the generator set was rumbling every day, the windows could not be opened, and the black smoke was choking and making people cough. The reason is that due to the construction of a power plant near a certain community, the black smoke and noise from the diesel generator sets have caused a lot of trouble to the residents of the community. Haixing Power Technology technicians analyzed that: On the one hand, it may be a problem with the quality of the power generation unit itself, which did not meet relevant pollutant and noise emission standards. Haixing recommends repairing or eliminating diesel generator sets that have quality problems as soon as possible; on the other hand, it may be caused by black smoke or noise caused by a failure of the diesel generator set during use. Smoke from the generator set is generally produced when the diesel engine is under heavy load, such as when accelerating, climbing or overloading. It may also be a product of combustion. Under heavy load of the diesel engine, the temperature of the combustion chamber is high and too much fuel is injected. , the mixture is formed unevenly, there is insufficient air during combustion in local areas, and the fuel burns at high
