防火卷簾門用于建築物之間防火分隔使用。。使用電動電機進行操作卷簾門升降。。可與火災報警控制系統聯動使用。。防火卷簾門配置了煙感和感溫探測器。。當探測器動作時。。自動控制卷簾門下降。。達到防火分隔作用。防火卷簾門由簾板、卷軸、導軌、電動卷門機、限位器、手動速放關閉裝置、控制箱、煙溫感裝置、控制按鈕盒等組成。

電動卷簾門常見故障。。總結為四個方面：不動或轉速慢；=-；=手拉鏈不動；=-；=電機振動或噪聲較大；=-；=控制失效。

1；=-；=電動機不動或轉速慢

故障原因：電動機的線路斷路；=-；=電機燒損；=-；=停止按鈕沒有複位；=-；=限位開關動作；=-；=負載較大等引起；

處理方法：檢查線路並接通；更換燒損電機；更換按鈕或重複按動幾次；撥動限位開關滑塊使它脫離微動開關觸點。。調整開關位置；檢查機械有無卡阻。。若有則消除障礙物；

2；=-；=控制失效

故障原因：觸點粘死；=-；=行程微動開關失效或變形；=-；=滑塊緊定螺釘松；=-；=靠板螺絲松使靠板移位。。使滑塊或螺母不能隨絲杆轉動而移動；=-；=限位器傳動齒輪破損；=-；=按鈕上；=-；=下鍵卡死；

處理方法：更換繼電器；更換微動開關或觸片；緊定滑塊螺釘並使靠板複位；更換限位器傳動齒輪；更換按鈕；

3；=-；=手拉鏈不動

故障原因：環形鏈條堵住十字槽；棘爪無脫離棘輪；壓鏈架卡死；

處理方法：理順環形鏈條；調整棘爪與壓鏈架相對位置；更換或潤滑銷軸；

4；=-；=電機振動或噪聲較大

故障原因：刹車盤不平衡或斷裂；刹車盤無緊固；軸承失油或失效；齒輪齧合不順；=-；=失油或磨損嚴重；電機電流聲或振動；

Fire shutter doors are used for fire separation between buildings.. Use electric motor to operate rolling door lifting.. It can be used in conjunction with fire alarm control system.. The fire shutter door is equipped with smoke detector and temperature detector.. When the detector moves.. Automatic control, rolling door falling.. Fire compartmentation. The fireproof rolling door is composed of a curtain board, a reel, a guide rail, an electric rolling door machine, a spacing device, a manual speed closing device, a control box, a smoke temperature sensing device, a control button box, etc..

Common problems of electric shutter doors.. Summarized into four aspects: real or slow speed; =; = hand = = zipper fixed; motor; vibration or noise; = = failure; control.

= = 1;; real or slow speed motor

Fault: circuit breaker circuit of the motor; =; = = =; electric motor; the stop button does not reset; =; = limit switch; =; = load caused by;

Processing method: check the line and switch on; replace the burning motor; replace the button or repeat it several times; switch the limit switch slider to make it out of the microswitch contact.. Adjust the switch position; check whether the machine is clamped or not.. If so, remove the obstruction;

2 = = failure; control;

Fault: Contact stuck; =; = stroke inching switch failure or deformation; =; = slider locking screws loose; =; = by plate screw loose on board to shift.. The slider or nut does not move with the screw rod to rotate; = = limiter; transmission gear breakage; =; =; = = button; key lock;

Processing method: replace relay; replace micro switch or contact piece; tighten the slider screw and make the backing plate reset; change the spacing device to drive gear; replace the button;
