一般要求啟閉機能在2min內(nèi)將快速閘門關(guān)閉。同時為防止閘門底緣和底檻因猛烈碰撞而損壞，快速卷揚啟閉機應(yīng)設(shè)有限速裝置，將閘門接近底檻時的下降速度限制在5m/min以內(nèi)，但下降過程中的速度并無限制要求，只要不對啟閉機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.
快速閘門在正常啟閉時，對啟閉速度并無特殊要求，因此快速卷揚式啟閉機還應(yīng)具備普通卷揚機的功能?？焖匍l門啟閉機，應(yīng)有就地操作和遠方操作兩套系統(tǒng)，并應(yīng)配有可靠電源。遠方銹鋼鑄件  螺桿式啟閉機 保定搬家 電纜掛鉤 沖壓機  防撞護欄模具操作系統(tǒng)可用來操作閘門的正常閉門和事故快速閉門，《鋼閘門設(shè)計規(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方啟門，但有些泵站為了實現(xiàn)自動控制，也具備遠方啟門的功能。為保證電源供應(yīng)，遠方操作系統(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；機組或鋼管發(fā)生事故時，故障信號應(yīng)能激發(fā)遠方操作系統(tǒng)直流電源自動控制閘門快速閉門。
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.
