  螺桿啟閉機(jī)的主要優(yōu)點(diǎn)是,機(jī)體個(gè)小,且封閉,構(gòu)造簡(jiǎn)單,使用起來(lái)牢固可靠,管理與養(yǎng)護(hù)較方便。螺桿和螺母有自鎖作用,閘門能夠停留在任何位置而不自行滑落,所以比較安全。在螺桿長(zhǎng)細(xì)比許可的范圍內(nèi)能夠?qū)﹂l門施加閉門力作用。

啟閉機(jī)

  它的缺點(diǎn)是,由于螺桿式啟閉機(jī)體沒(méi)有減速或減速程序少;因而限制了它的啟閉能力,常用的噸位較小,一般5-10 t左右。螺桿式啟閉機(jī)易因設(shè)計(jì)不周、安裝不準(zhǔn)確或操作不當(dāng)而將螺桿壓彎,影響閘門的啟閉。有時(shí),因機(jī)座及啟閉臺(tái)大梁錨固不牢,在閉門力過(guò)大時(shí),容易將機(jī)體本身甚至將啟閉臺(tái)大梁整個(gè)抬起。
