燃气发电机组出现空气动力噪声表现

返回 2022.05.13 来源:http://bjshhj.com
燃气发电机组由燃气发动机、发电机、控制柜等部件组成。燃气发动机和发电机安装在同一个钢制底盘上。那么你知道燃气发电机组出现空气动力噪声表现是什么吗?
The gas generator set is composed of gas engine, generator, control cabinet and other components. The gas engine and generator are installed on the same steel chassis. So do you know the performance of aerodynamic noise in gas generator set?
燃气发电机组噪声是由多种声源组成的复杂声源。按噪声辐射方式可分为气动噪声、表面辐射噪声和电磁噪声。根据产生的原因,康明斯燃气发电机的表面辐射噪声可分为燃烧噪声和机械噪声。其中,空气动力噪声是主要噪声源。
The noise of gas generator set is a complex sound source composed of many 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 causes, the surface radiation noise of Cummins gas generator can be divided into combustion noise and mechanical noise. Among them, aerodynamic noise is the main noise source.
气动噪声是由于气体的非稳态过程,即气体的扰动和气体与物体的相互作用而引起的。空气动力噪声直接辐射到大气中,包括进气噪声、排气噪声和冷却风扇噪声。
Aerodynamic noise is caused by the unsteady process of gas, that is, the disturbance of gas and the interaction between gas and object. Aerodynamic noise radiates directly into the atmosphere, including intake noise, exhaust noise and cooling fan noise.
燃气发电机组的燃烧噪声和机械噪声很难严格区分。通常,由气缸内燃烧形成的压力波动通过气缸盖、活塞、连杆、曲轴和机体而辐射的噪声称为燃烧噪声。
It is difficult to strictly distinguish the combustion noise and mechanical noise of gas generator set. Generally, the noise radiated by the pressure fluctuation formed by combustion in the cylinder through the cylinder head, piston, connecting rod, crankshaft and body is called combustion noise.
活塞对缸套的冲击以及运动部件的机械冲击和振动所产生的噪声称为机械噪声。一般来说,燃气机的燃烧噪声高于机械噪声,而非直喷燃气机的机械噪声高于燃烧噪声。但低速运行时燃烧噪声高于机械噪声,电磁噪声是燃气发电机组转子在电磁场中高速旋转产生的。
The noise generated by the impact of piston on cylinder liner and the mechanical impact and vibration of moving parts is called mechanical noise. Generally speaking, the combustion noise of gas engine is higher than the mechanical noise, while the mechanical noise of non direct injection gas engine is higher than the combustion noise. However, the combustion noise during low-speed operation is higher than the mechanical noise. The electromagnetic noise is caused by the high-speed rotation of the rotor of the gas generator set in the electromagnetic field.
发电机组的安装和使用,请严格按照说明书的要求进行。请先检查润滑油(油)、冷却液(水箱)、燃油(燃气)油的油位。检查燃气机供油、润滑、冷却等系统的管路和接头是否有漏水、漏油现象,电路有无破皮等漏电隐患;地线等电路是否松动;机组与基础的连接是否牢固。
Please install and use the generator set in strict accordance with the requirements of the manual. Please check the oil level of lubricating oil (oil), coolant (water tank) and fuel (gas) oil first. Check whether the pipelines and joints of fuel supply, lubrication and cooling systems of gas engine have water leakage and oil leakage, and whether the circuit has potential leakage hazards such as skin damage; Whether the ground wire and other circuits are loose; Whether the connection between the unit and the foundation is firm.
燃气发电机组
打开电动开关,按下启动按钮或启动电锁,按住按钮3-5秒。如果启动不成功,请等待大约两分钟后再重试。若三启动不成功,停止启动,排除蓄电池电压或油路等故障因素,再启动。严禁带负载低速启动。
Turn on the electric switch, press the start button or start the electric lock, and press and hold the button for 3-5 seconds. If the startup is not successful, please wait about two minutes and try again. If the third start is unsuccessful, stop the start, eliminate the fault factors such as battery voltage or oil circuit, and then start. It is forbidden to start at low speed with load.
启动时,应观察油压。如果油压不显示或很低,应立即停机检查。机组启动后,检查控制箱模块或仪表参数:油压、水温、电压、频率等。注意机组的连接和牢固性,是否有松动和剧烈振动。
When starting, observe the oil pressure. If the oil pressure does not show or is very low, stop the machine immediately for inspection. After the unit is started, check the control box module or instrument parameters: oil pressure, water temperature, voltage, frequency, etc. Pay attention to the connection and firmness of the unit, and whether there is looseness and violent vibration.
