消防通风机在酒店、等公共封闭场所是必不可少的。它是一种用于输送气体的机械。从能量的角度来看，它是一种将原动机的机械能转化为气体能的机械。根据其结构和工作原理，通风机广泛应用于各个工业部门。一般来说，离心式通风机适用于小流量、高压力，轴流式通风机常用于大流量、低压力。

Fire ventilator is essential in public closed places such as hotels and shopping malls. It is a machine for conveying gas. From the perspective of energy, it is a kind of machinery that converts the mechanical energy of prime mover into gas energy. According to its structure and working principle, fans are widely used in various industrial departments. Generally speaking, centrifugal fans are suitable for small flow and high pressure, and axial fans are commonly used for large flow and low pressure.

消防通风机是消防系统中的一种防排烟系统。一般与火灾报警主机联动。

Fire ventilator is a kind of smoke control system in fire protection system. It is generally linked with the fire alarm host.

所述排烟消防阀设置在消防风机与排烟管道的连接处，所述排烟阀设置在排烟管道的末端。需要注意的是，排烟阀和排烟防火阀是完全不同的设备，具有不同的功能。排烟阀通常关闭，火灾时打开，并与报警主机联动。开启条件是自动报警系统有火灾报警(探测器报警)，火灾报警主机置于自动状态，排烟阀自动打开，联动排烟风机启动。排烟消防阀平时常开，遇火灾时也常开。但当排烟温度达到280℃时，排烟防火阀自动关闭，已开启的已连接风机停止运行。

The smoke exhaust fire valve is arranged at the connection between the fire fan and the smoke exhaust pipe, and the smoke exhaust valve is arranged at the end of the smoke exhaust pipe. It should be noted that smoke exhaust damper and smoke exhaust fire damper are completely different equipment and have different functions. The smoke exhaust valve is usually closed, opened in case of fire, and linked with the alarm host. The opening condition is that the automatic alarm system has fire alarm (detector alarm), the fire alarm host is in automatic state, the smoke exhaust valve is opened automatically, and the linkage smoke exhaust fan is started. The smoke exhaust valve is usually open in case of fire. However, when the smoke exhaust temperature reaches 280 ℃, the smoke exhaust fire damper will automatically close and the opened connected fan will stop running.

石家庄消防通风机的工作原理基本如下。但消防风机完成上述工作的前提是消防风机的控制箱(机)处于自动工作状态。当消防风机的控制箱(机)置于手动状态时，不会与火灾报警系统联动。

The working principle of Shijiazhuang fire ventilator is basically as follows. However, the premise for the fire fan to complete the above work is that the control box (machine) of the fire fan is in automatic working state. When the control box (machine) of the fire fan is in manual state, it will not be linked with the fire alarm system.

消防通风机的安装亦须符合下列规定

The installation of fire ventilator shall also comply with the following requirements

1.风机试运行时，叶轮按正确方向旋转。运行不少于2h后，滑动轴承温升不超过35℃，温度不超过70℃;滚动轴承温升不超过40℃，温度不超过80℃

1. During the trial operation of the fan, the impeller rotates in the correct direction. After running for not less than 2h, the temperature rise of sliding bearing shall not exceed 35 ℃ and the maximum temperature shall not exceed 70 ℃; The temperature rise of rolling bearing shall not exceed 40 ℃, and the maximum temperature shall not exceed 80 ℃

2.离心风机与阻尼台紧密接触，螺栓拧紧，设有防松装置

2. The centrifugal fan is in close contact with the damping table, the bolts are tightened, and an anti loosening device is set

3.管路风机安装减振吊架时，风机与减振吊架连接紧密，牢固可靠;当风机通过支架和支架安装时，风机与减震器、支架、支架紧密连接，稳定可靠。

3. When the pipeline fan is installed with the vibration damping hanger, the fan and the vibration damping hanger are closely connected, firm and reliable; When the fan is installed through the support and bracket, the fan is closely connected with the shock absorber, bracket and bracket, which is stable and reliable.
