菏澤電動扶梯為您解答扶手為何總比梯級快？

2021-12-09 11:14:03

站在自動扶梯上扶著扶手，不一會兒你就會發(fā)現(xiàn)自己的手先跑前面去了。這種現(xiàn)象在有的自動扶梯上明顯，有的不明顯，你甚至還或許遇到過反過來的狀況。是自動扶梯出問題了嗎？菏澤電動扶梯接下來為您解答。

菏澤電動扶梯告訴您自動扶梯的梯級和扶手分別是由不同的傳動系統(tǒng)控制的。根據(jù)國家標(biāo)準(zhǔn)（GB16899-2011）對自動扶梯的要求：“每一扶手裝置的頂部應(yīng)裝有運(yùn)轉(zhuǎn)的扶手帶，其運(yùn)轉(zhuǎn)方向應(yīng)與梯級、踏板或膠帶相同。在正常運(yùn)轉(zhuǎn)條件下，扶手帶的運(yùn)轉(zhuǎn)速度相對于梯級、踏板或膠帶實(shí)踐速度的允差為0%～+2%?！?這就意味著扶手帶只能與梯級完全同步，或許略快一點(diǎn)，快2%。理想的作用當(dāng)然是完全同步，可是機(jī)器不免呈現(xiàn)損耗。驅(qū)動系統(tǒng)中扶手帶的磨損、張緊彈簧的壓力形變、以及乘客對扶手帶的壓力等因素都會影響扶手的運(yùn)轉(zhuǎn)速率。

菏澤電動扶梯也提示各位隨著扶手傳動裝置的老化，扶手的速度會變得越來越慢。為了補(bǔ)償這一點(diǎn)，新扶梯一般規(guī)劃得比梯級略快，之后就會漸漸同步。不過，再往后扶手就或許比梯級更慢。這種狀況比扶手快一步更風(fēng)險(xiǎn)，因?yàn)槿说纳眢w中心會被往后帶，導(dǎo)致后仰跌倒，所以自動扶梯還得定期保護(hù)。
