消防通風(fēng)機(jī)在酒店、等公共封閉場(chǎng)所是必不可少的。它是一種用于輸送氣體的機(jī)械。從能量的角度來(lái)看，它是一種將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)化為氣體能的機(jī)械。根據(jù)其結(jié)構(gòu)和工作原理，通風(fēng)機(jī)廣泛應(yīng)用于各個(gè)工業(yè)部門(mén)。一般來(lái)說(shuō)，離心式通風(fēng)機(jī)適用于小流量、高壓力，軸流式通風(fēng)機(jī)常用于大流量、低壓力。

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.

消防通風(fēng)機(jī)是消防系統(tǒng)中的一種防排煙系統(tǒng)。一般與火災(zāi)報(bào)警主機(jī)聯(lián)動(dòng)。

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

所述排煙消防閥設(shè)置在消防風(fēng)機(jī)與排煙管道的連接處，所述排煙閥設(shè)置在排煙管道的末端。需要注意的是，排煙閥和排煙防火閥是完全不同的設(shè)備，具有不同的功能。排煙閥通常關(guān)閉，火災(zāi)時(shí)打開(kāi)，并與報(bào)警主機(jī)聯(lián)動(dòng)。開(kāi)啟條件是自動(dòng)報(bào)警系統(tǒng)有火災(zāi)報(bào)警(探測(cè)器報(bào)警)，火災(zāi)報(bào)警主機(jī)置于自動(dòng)狀態(tài)，排煙閥自動(dòng)打開(kāi)，聯(lián)動(dòng)排煙風(fēng)機(jī)啟動(dòng)。排煙消防閥平時(shí)常開(kāi)，遇火災(zāi)時(shí)也常開(kāi)。但當(dāng)排煙溫度達(dá)到280℃時(shí)，排煙防火閥自動(dòng)關(guān)閉，已開(kāi)啟的已連接風(fēng)機(jī)停止運(yùn)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.

石家莊消防通風(fēng)機(jī)的工作原理基本如下。但消防風(fēng)機(jī)完成上述工作的前提是消防風(fēng)機(jī)的控制箱(機(jī))處于自動(dòng)工作狀態(tài)。當(dāng)消防風(fēng)機(jī)的控制箱(機(jī))置于手動(dòng)狀態(tài)時(shí)，不會(huì)與火災(zāi)報(bào)警系統(tǒng)聯(lián)動(dòng)。

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.

消防通風(fēng)機(jī)的安裝亦須符合下列規(guī)定

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

1.風(fēng)機(jī)試運(yùn)行時(shí)，葉輪按正確方向旋轉(zhuǎn)。運(yùn)行不少于2h后，滑動(dòng)軸承溫升不超過(guò)35℃，溫度不超過(guò)70℃;滾動(dòng)軸承溫升不超過(guò)40℃，溫度不超過(guò)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.離心風(fēng)機(jī)與阻尼臺(tái)緊密接觸，螺栓擰緊，設(shè)有防松裝置

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

3.管路風(fēng)機(jī)安裝減振吊架時(shí)，風(fēng)機(jī)與減振吊架連接緊密，牢固可靠;當(dāng)風(fēng)機(jī)通過(guò)支架和支架安裝時(shí)，風(fēng)機(jī)與減震器、支架、支架緊密連接，穩(wěn)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.
