3c消防风机和排风机的区别
The difference between 3C fire fan and exhaust fan

3c消防排烟风机的流量又叫做气体的体积流量，一般表示为气体在单位时间内流过通风机入口截面的体积。
The flow of 3C fire smoke exhaust fan is also called the volume flow of gas, which is generally expressed as the volume of gas flowing through the fan inlet section in unit time.

如果没有特别指出的情况下，流量均指标准状况下的气体体积。由于气体自重很小，所以可以忽略不计。
If not specified, the flow refers to the volume of gas under standard conditions. Since the self weight of gas is very small, it can be ignored.

风机的静压是指标准状况下，单位气体存在的势能，动压是指标准状况下，单位气体存在的动能，通常把气体的全压称为3c消防排烟风机的压力。
The static pressure of fan refers to the potential energy of unit gas under the standard condition, and the dynamic pressure refers to the kinetic energy of unit gas under the standard condition. Generally, the total pressure of gas is called the pressure of 3C fire smoke exhaust fan.



1. 普通的排风机一般应用于日常通风，起到帮助空气流通，使之不断有新鲜空气流入，保证氧气含量的作用。排风机的转速较低，且一般配备有消声器，发出的噪声较小。
1. The common exhaust fan is generally used for daily ventilation to help the air flow, make it continuously have fresh air inflow, and ensure the oxygen content. The speed of exhaust fan is low, and it is generally equipped with muffler, so the noise is small.

2.而3c消防风机属于消防通风设备，平时不开启，当有火情发生时由主机控制启动，起到将火灾现场烟气排除的作用，避免室内人员窒息或吸入过量有毒害气体。3c消防风机对转速要求较高，其必须达到一定的转速水平，因此所产生的噪声也较高。
2.The 3C fire fan belongs to the fire ventilation equipment, which is not opened at ordinary times. When there is a fire, it is controlled and started by the main engine, which plays the role of exhausting the smoke at the scene of the fire, so as to avoid the suffocation of indoor personnel or inhalation of excessive toxic gas. 3C fire-fighting fan has a high speed requirement, which must reach a certain speed level, so the noise generated is also high.



3. 3c消防风机需要具有一定的耐高温水平，其电缆须采用NH型，一般要求需要由双电源供电，如果不具备双电源时要在主机控制柜内加装符合要求的备用蓄电池。
3. 3C fire fan needs to have a certain level of high temperature resistance, and its cable must be NH type. Generally, it needs to be powered by dual power supply. If there is no dual power supply, it is necessary to install a qualified backup battery in the main control cabinet.

4.在有些空间利用要求比较高的场所，可以采用满足通风流量及风压要求的双速消防通风设备，即3c消防风机和排风机使用同一套设备，在日常低速运转做通风换气工作，一旦主机接收到反馈的火灾信号，立即控制风机高速运转，起到消防排烟的效果。
4. In some places with high requirements for space utilization, two speed fire ventilation equipment meeting the requirements of ventilation flow and air pressure can be used, i.e. 3C fire fan and exhaust fan use the same set of equipment to conduct ventilation and air exchange work in daily low-speed operation. Once the main engine receives the feedback fire signal, the high-speed operation of the fan shall be controlled immediately to achieve the effect of fire control and smoke exhaust.
