一般要求啟閉機(jī)能在2min內(nèi)將快速閘門(mén)關(guān)閉。同時(shí)為防止閘門(mén)底緣和底檻因猛烈碰撞而損壞，快速卷?yè)P(yáng)啟閉機(jī)應(yīng)設(shè)有限速裝置，將閘門(mén)接近底檻時(shí)的下降速度限制在5m/min以?xún)?nèi)，但下降過(guò)程中的速度并無(wú)限制要求，只要不對(duì)啟閉機(jī)零部件造成損害即可。
Generally, the opening and closing function is required to close the fast gate within 2 minutes. At the same time, to prevent damage to the bottom edge and bottom sill of the gate due to violent collision, the fast winch hoist should be equipped with a speed limiting device to limit the lowering speed of the gate when approaching the bottom sill to within 5m/min. However, there is no limit on the speed during the lowering process, as long as there is no damage to the hoist components.
快速閘門(mén)在正常啟閉時(shí)，對(duì)啟閉速度并無(wú)特殊要求，因此快速卷?yè)P(yáng)式啟閉機(jī)還應(yīng)具備普通卷?yè)P(yáng)機(jī)的功能。快速閘門(mén)啟閉機(jī)，應(yīng)有就地操作和遠(yuǎn)方操作兩套系統(tǒng)，并應(yīng)配有可靠電源。遠(yuǎn)方銹鋼鑄件  螺桿式啟閉機(jī) 保定搬家 電纜掛鉤 沖壓機(jī)  防撞護(hù)欄模具操作系統(tǒng)可用來(lái)操作閘門(mén)的正常閉門(mén)和事故快速閉門(mén)，《鋼閘門(mén)設(shè)計(jì)規(guī)范》（SL74-2013） 規(guī)定。
During normal opening and closing of the fast gate, there is no special requirement for the opening and closing speed, so the fast winch hoist should also have the function of an ordinary winch. The fast gate hoist should have two sets of systems: local operation and remote operation, and should be equipped with a reliable power supply. The remote operating system can be used to operate the normal closing and emergency fast closing of the gate, as stipulated in the "Design Specification for Steel Gates" (SL74-2013).
從安全角度考慮不提倡遠(yuǎn)方啟門(mén)，但有些泵站為了實(shí)現(xiàn)自動(dòng)控制，也具備遠(yuǎn)方啟門(mén)的功能。為保證電源供應(yīng)，遠(yuǎn)方操作系統(tǒng)除采用交流電源控制正常啟閉外，還應(yīng)采用由蓄電池室內(nèi)蓄電池組供應(yīng)的直流電源控制事故快速閉門(mén)；機(jī)組或鋼管發(fā)生事故時(shí)，故障信號(hào)應(yīng)能激發(fā)遠(yuǎn)方操作系統(tǒng)直流電源自動(dòng)控制閘門(mén)快速閉門(mén)。
From a safety perspective, remote door opening is not recommended, but some pumping stations also have the function of remote door opening in order to achieve automatic control. To ensure power supply, in addition to using AC power to control normal opening and closing, the remote operating system should also use DC power supplied by the indoor battery pack to control emergency fast door closing; When an accident occurs in the unit or steel pipe, the fault signal should be able to trigger the remote operating system's DC power supply to automatically control the rapid closing of the gate.
