    Solutions to noise reduction of diesel generator set
    Solutions to noise reduction of emergency generator the types of electric power generation is a kind of mechatronics equipment that converts the chemical energy of fuel into electrical energy. Today, with the increasing modernization, especially with the vigorous development of computer networks and communications, the equipment also has requirements for the reliability of power supply. Increasingly, because the UPS power supply has the problem of short power supply time. This makes diesel generator sets have a broad space for development, but while diesel silent generator provide convenience for people, the noise of the generator sets directly affects people's health, work and life. With the gradual improvement of people's environmental requirements, how to solve and overcome the above problems has become the key to the application and development of diesel generator sets. Here we focus on the occurrence and solutions of diesel generator sets. According to the working principle of diesel generator sets, the generation of noise is very complicated, which can be divided into the reasons and locations: 1. Exhaust noise; 2. Mechanical noise; 3. Combustion noise; 4. Cooling fan and exhaust noise; 5 .Inlet wind noise: 6. Generator noise. The following is an explanation of these six parts: 1. Exhaust noise: Exhaust noise is a high-temperature, high-speed pulsating airflow noise, which is the most energy and component part of engine noise. It is much higher than the intake noise and the mechanical noise radiated by the body, and it is the most important part of the total engine noise. Its fundamental frequency is the firing frequency of the engine. The main components of exhaust noise are the following: low-frequency pulsating noise caused by periodic exhaust smoke, air column resonance noise in the exhaust pipe, Helmholtz resonance noise of the cylinder, high-speed airflow through the valve gap and tortuous pipes When the noise, eddy current noise, and the regenerated noise generated by the pressure wave in the exhaust system are excited by the pressure wave in the pipe, the noise frequency increases significantly with the increase of the airflow speed. 2. Mechanical noise: Mechanical noise is mainly caused by the gas Vibration or mutual impact caused by the periodic changes of pressure and motion inertia force, the most serious of which are the following: the noise of the piston crank connecting rod mechanism, the noise of the valve train, the noise of the transmission gear, and the unbalanced inertia Mechanical vibration and noise caused by force. The strong mechanical vibration of the diesel generator set can spread to various places outdoors through the foundation long distance, and then form noise through the radiation of the ground. This kind of structural noise spreads far and attenuates, and once it is formed, it is difficult to isolate it. 3.Combustion noise: Combustion noise is the structural vibration and noise produced by diesel fuel during...

  • Affected By The Epidemic, New Energy Power Generation Project Faces Delays In India
    Affected By The Epidemic, New Energy Power Generation Project Faces Delays In India
    Affected by the epidemic, India's 3000MW new energy power generation project faces delays According to Wood Mackenzie Consulting, India may face delays in 3,000 MW photovoltaic and wind energy projects supplier generator diesel 1500kva selangor due to the impact of the coronavirus epidemic. The research and consulting company pointed out that because the first quarter is usually one of the busiest periods for most efficient diesel generator wind energy project installation. Analysts said that the epidemic will postpone certain projects until the summer. If the epidemic is extended beyond April, the construction of wind farms may be further postponed to the monsoon season, where wind energy installations are usually the lowest during the monsoon season. " As the construction of impotance of power generator set planned to be completed in 2020 exceeds 3 GW, the current epidemic and labor disruption may postpone the 400 MW project to 2021, which is equivalent to a reduction in the construction ratio of 11% in 2020. India's photovoltaic industry is also expected to suffer a heavy blow, because the industry is heavily dependent on the supply of Chinese photovoltaic modules (accounting for 80% of the total). "The current supply and labor disruptions will have a huge negative impact on construction in 2020. The first quarter is expected to be severely affected, compared with about 3GW in the first quarter of 2019, a year-on-year decrease of 1.2GW." Analysts said. As supply and logistics bottlenecks still exist, Wood Mackenzie Consulting remains cautious about the prospects of the Indian photovoltaic industry in the second half of the year. Therefore, its annual decline was 2.9 GW, a decrease of 24.8%. The Indian states with the highest rates of coronavirus infection also correspond to regions that are conducive to the development of wind and solar energy. Gujarat added 58% of wind energy or 1.4 GW of new wind energy to India in 2019. As far as the impact of the coronavirus epidemic is concerned, Gujarat is one of the ten worst-hit states. In terms of solar energy, Karnataka (2.0 GW), Tamil Nadu (1.6 GW) and Rajasthan (1.7 GW) are the top three states, accounting for 55% of solar photovoltaic installed capacity in 2019. Wood Mackenzie Consulting said, "Analysts believe that the current support measures taken by the Indian government to alleviate the economic downturn are necessary, but if the epidemic continues to escalate, it will adversely affect the cash flow of photovoltaic and wind energy companies."
