Exhaust smoke fan:

排煙風(fēng)機(jī)反轉(zhuǎn)通常會有逆向的風(fēng)。排煙風(fēng)機(jī)反向旋轉(zhuǎn)，使之產(chǎn)生反向的風(fēng)。排煙風(fēng)機(jī)是將廚房中加工食物過程中產(chǎn)生的異味、高溫、油煙氣體迅速排走的機(jī)械。廚房中各種煎、炒、蒸、煮、炸、烤等設(shè)備在加工食物過程中不斷產(chǎn)生各種高溫、潮濕、污染的氣體。累計到一定程度、廚房將不適直繼續(xù)工作.需要使用風(fēng)機(jī)將污染氣體經(jīng)由排煙管道排出廚房。

The reverse direction of the smoke exhaust fan usually results in reverse wind. The smoke exhaust fan rotates in the opposite direction, causing it to generate reverse wind. Smoke exhaust fan is a mechanical device that quickly removes odors, high temperatures, and fumes generated during food processing in the kitchen. Various equipment in the kitchen, such as frying, frying, steaming, boiling, frying, and grilling, constantly produce various high temperature, humid, and polluting gases during the processing of food. If it accumulates to a certain extent, the kitchen will become uncomfortable and continue working. It is necessary to use a fan to exhaust the polluted gas from the kitchen through the exhaust pipe.

消防排煙風(fēng)機(jī)：

Fire exhaust fan:

消防排煙風(fēng)機(jī)主要是指當(dāng)室內(nèi)發(fā)生火災(zāi)的時候，會冒出很多的濃煙，它作用就是將這些濃煙排出室內(nèi)。消防排煙風(fēng)機(jī)有一個排煙閥，排煙閥平時你都是關(guān)著的，當(dāng)火災(zāi)發(fā)生的時候自動開啟，它是與報警主機(jī)連著的，開啟的條件是自動報警系統(tǒng)發(fā)生火警消防報警主機(jī)處于自動狀態(tài)，消防排煙閥自動開啟，聯(lián)動消防排煙風(fēng)機(jī)啟動。消防排煙風(fēng)機(jī)的作用。它主要使用于高層建筑、地下室、大型廚房等等。

The fire exhaust fan mainly refers to the smoke that emits a lot of thick smoke when a fire occurs indoors, and its function is to exhaust these thick smoke indoors. The fire exhaust fan has a smoke exhaust valve, which is usually closed by you. When a fire occurs, it automatically opens and is connected to the alarm host. The opening condition is that the automatic alarm system generates a fire alarm, and the fire alarm host is in an automatic state. The fire exhaust valve automatically opens and the linkage fire exhaust fan starts. The role of fire exhaust fans. It is mainly used in high-rise buildings, basements, large kitchens, and so on.

排油煙風(fēng)機(jī)風(fēng)閥和消防排煙風(fēng)機(jī)風(fēng)閥雖然都是防排煙系統(tǒng)，但它們是完全不同的產(chǎn)品，排煙管道未端設(shè)置排煙閥，排煙風(fēng)機(jī)與排煙管道連接處設(shè)置排煙防火閥。要注意排煙閥與排煙防火閥是功能完全不同的設(shè)備。

Although both the oil smoke exhaust fan and fire smoke exhaust fan are smoke control systems, they are completely different products. Smoke exhaust pipes are not equipped with smoke exhaust valves at the end, and smoke exhaust fire dampers are installed at the connection between the smoke exhaust fan and the smoke exhaust pipe. It should be noted that smoke exhaust valves and smoke fire dampers are devices with completely different functions.

排煙閥平時常關(guān)，火災(zāi)時開，與報警主機(jī)聯(lián)動，開啟條件是自動報警系統(tǒng)發(fā)生火警（探測器報警）消防報警主機(jī)置于自動狀態(tài)，消防排煙閥自動開啟，聯(lián)動消防排煙風(fēng)機(jī)啟動。

The smoke exhaust valve is usually closed and opened in case of a fire. It is linked to the alarm host. The opening condition is that the automatic alarm system generates a fire alarm (detector alarm), and the fire alarm host is in automatic mode. The fire exhaust valve automatically opens, and the linked fire exhaust fan starts.

排煙防火閥是平時常開，火災(zāi)時也是開啟狀態(tài)，但當(dāng)煙氣溫度達(dá)到280℃時，排煙防火閥自動關(guān)閉，聯(lián)動已經(jīng)開啟的風(fēng)機(jī)停止運行，消防報警主機(jī)聯(lián)動的排煙風(fēng)機(jī)在消防系統(tǒng)中都屬于防排煙系統(tǒng)。但消防排煙風(fēng)機(jī)完成上述工作的前提是排煙消防風(fēng)機(jī)控制柜置于自動工作狀態(tài)，消防排煙風(fēng)機(jī)的工作原理大致就這么多。主要是起消防通風(fēng)作用，注意當(dāng)風(fēng)機(jī)控制柜置于手動狀態(tài)時，不會與消防報警系統(tǒng)聯(lián)動.

The smoke exhaust fire damper is usually open, and it is also in the open state during a fire. However, when the smoke temperature reaches 280 ℃, the smoke exhaust fire damper automatically closes, and the fan that has been linked to it stops running. The smoke exhaust fan that is linked to the fire alarm host belongs to the smoke exhaust system in the fire protection system. But the premise for the fire exhaust fan to complete the above work is that the control cabinet of the smoke exhaust fan is placed in automatic operation, and the working principle of the fire exhaust fan is roughly as follows. Mainly used for fire ventilation, please note that when the fan control cabinet is in manual mode, it will not be linked with the fire alarm system
