Rolling shutter doors must be known to all of you. With the development of the times, rolling shutter doors have appeared in large and small streets, from supermarkets and restaurants in villages and towns to large shopping malls in cities and commercial streets. We can see the figure of rolling shutter doors in commercial streets. We may use them for a long time. A series of failures will occur in the rolling shutter doors, and they will not repair them. It is common to repair rolling shutter doors in Jinan What is the cause of the fault? What is the cause? How to solve it? Let's watch the following to find out!

1、馬達不能動或速度慢。這種常見故障應(yīng)由電路斷路、電機過熱、緊急停止按鈕未復(fù)位以及負載過重的限位開關(guān)引起。解決方法：抽查線路并嘗試連接;拆卸并更換燒毀的電機;更換按鈕或按幾次;撥動限位開關(guān)的滑塊部分，離開微動開關(guān)的接觸位置，同時調(diào)整微動開關(guān)的位置;檢查機械部件有無堵塞，如果有，堵塞并障礙物。

1. The motor doesn't work or is slow. This common fault is caused by open circuit, overheated motor, non reset of emergency stop button and overload limit switch. Solutions: spot check the circuit and try to connect it; dismantle and replace the burned motor; replace the button or press several times; move the slider part of the limit switch to leave the contact position of the microswitch, and adjust the position of the microswitch; check whether the mechanical parts are blocked, if any, remove the blockage and remove the obstacles.

2.控制無效。確定故障的位置和原因：接觸器的觸點被卡住，行程微動開關(guān)無效或接觸板變形，滑塊定位螺釘松動，背板螺釘松動導(dǎo)致背板移位，導(dǎo)致滑塊或螺母不能隨螺桿的轉(zhuǎn)動而移動到相應(yīng)的位置，或限位器的傳動齒輪損壞，按鈕開關(guān)的上下鍵壞死。處理方法：更換接觸器;更換微動開關(guān)或觸點;擰緊滑塊螺釘并復(fù)位支撐板;更換限制器的傳動齒輪;更換按鈕。

2. Ineffective control. Determine the location and cause of the fault: the contact of the contactor is stuck, the travel microswitch is invalid or the contact plate is deformed, the slider positioning screw is loose, and the back plate screw is loose, which causes the back plate to shift, resulting in the slider or nut unable to move to the corresponding position with the screw rotation, or the transmission gear of the limiter is damaged, and the up and down keys of the button switch are necrotic. Treatment methods: replace the contactor; replace the microswitch or contact; tighten the slider screw and reset the support plate; replace the transmission gear of the limiter; replace the button.

3.手拉鏈卡住了。故障原因：圓環(huán)鏈堵塞十字槽;棘爪沒有分離棘輪;壓鏈器卡住了。處理方法：理順圓環(huán)鏈;調(diào)節(jié)棘爪與壓鏈架相對位置;更換或潤滑銷軸。

3. The zipper is stuck. Fault causes: the ring chain blocked the cross groove; the pawl did not separate the ratchet; the chain press was stuck. Treatment method: straighten out the ring chain; adjust the relative position between the pawl and the chain holder; replace or lubricate the pin shaft.

4.電機振動或噪音原因：制動盤安裝不平衡或內(nèi)部斷裂;制動盤緊固不當;沒有軸承潤滑油;齒輪嚙合不良，接觸部位無潤滑油或磨損嚴重;電機電流噪音或振動。處理方法：更換制動盤或重新調(diào)整平衡;擰緊制動盤螺母;更換軸承。修理、潤滑或更換電機軸的輸出齒輪;檢查電機，如果損壞，請更換。

4. Causes of motor vibration or noise: unbalanced installation or internal fracture of brake disc; improper fastening of brake disc; no bearing lubricating oil; poor gear meshing, no lubricating oil or serious wear at contact parts; motor current noise or vibration. Treatment method: replace the brake disc or readjust the balance; tighten the brake disc nut; replace the bearing. Repair, lubricate or replace the output gear of the motor shaft; check the motor and replace if damaged.

5.檢查電動卷簾門的偏移和螺絲緊固度，檢查皮帶的緊固度，通過控制器檢查電機輸出清洗底盤內(nèi)部的油污和灰塵，通過開關(guān)門的寬度、速度和制動等檢查電壓參數(shù)是否正常修復(fù)。

5. Check the offset and screw tightness of the electric rolling shutter door, check the tightness of the belt, check the output of the motor through the controller, clean the oil and dust inside the chassis, and check whether the voltage parameters are normally repaired through the width, speed and braking of the door opening and closing.

大家要應(yīng)該進行定期的維護，這樣可以防止出現(xiàn)故障，以上內(nèi)容就是給大家所分享的濟南卷簾門維修中常見的故障原因及解決方法，如果根據(jù)上述內(nèi)容解決不了，請找維修人員。
