消防通風機在酒店、等公共封閉場所是必不可少的。它是一種用于輸送氣體的機械。從能量的角度來看,它是一種將原動機的機械能轉化為氣體能的機械。根據(jù)其結構和工作原理,通風機廣泛應用于各個工業(yè)部門。一般來說,離心式通風機適用于小流量、高壓力,軸流式通風機常用于大流量、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.
消防通風機是消防系統(tǒng)中的一種防排煙系統(tǒng)。一般與火災報警主機聯(lián)動。
Fire ventilator is a kind of smoke control system in fire protection system. It is generally linked with the fire alarm host.
所述排煙消防閥設置在消防風機與排煙管道的連接處,所述排煙閥設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備,具有不同的功能。排煙閥通常關閉,火災時打開,并與報警主機聯(lián)動。開啟條件是自動報警系統(tǒng)有火災報警(探測器報警),火災報警主機置于自動狀態(tài),排煙閥自動打開,聯(lián)動排煙風機啟動。排煙消防閥平時常開,遇火災時也常開。但當排煙溫度達到280℃時,排煙防火閥自動關閉,已開啟的已連接風機停止運行。
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.
石家莊消防通風機的工作原理基本如下。但消防風機完成上述工作的前提是消防風機的控制箱(機)處于自動工作狀態(tài)。當消防風機的控制箱(機)置于手動狀態(tài)時,不會與火災報警系統(tǒng)聯(lián)動。
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.
消防通風機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.風機試運行時,葉輪按正確方向旋轉。運行不少于2h后,滑動軸承溫升不超過35℃,溫度不超過70℃;滾動軸承溫升不超過40℃,溫度不超過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.離心風機與阻尼臺緊密接觸,螺栓擰緊,設有防松裝置
2. The centrifugal fan is in close contact with the damping table, the bolts are tightened, and an anti loosening device is set
3.管路風機安裝減振吊架時,風機與減振吊架連接緊密,牢固可靠;當風機通過支架和支架安裝時,風機與減震器、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.
