根據(jù)《消防給水及消火栓系統(tǒng)技術(shù)規(guī)范》GB50974-2014標(biāo)準(zhǔn)11.0.12條規(guī)定，本條為強制性條文，壓力啟動、遠(yuǎn)程啟動和硬拉線啟動都是通過繼電器來實現(xiàn)自動啟泵的，若繼電器和弱電信號故障不能自動啟動消防泵時，應(yīng)依靠消防泵控制柜設(shè)置的“機械應(yīng)急啟動裝置”直接啟動消防泵，當(dāng)弱電信號和硬拉線啟泵繼電器故障且消防泵控制柜內(nèi)二次線路故障和電器故障不能使消防泵自動或手動啟動，所以在火警緊急情況下，本條強制規(guī)定只要在正常供電情況下，無論消防泵控制柜內(nèi)控制線路損壞如何，都能強制直接啟泵，以保證火災(zāi)時撲救及時性，該“機械應(yīng)急啟動裝置”是通過機械連鎖裝置直接傳動，來實現(xiàn)直接啟動消防泵的裝置。該裝置可配置星三角啟動和軟啟動啟動兩種方式?！皺C械應(yīng)急啟動裝置”啟動手柄平時處于停止?fàn)顟B(tài)(帶鎖)，緊急火警時必須由被授權(quán)的管理人員操作(機械應(yīng)急啟動裝置帶鎖，平時由有權(quán)限的人保管，且此時從報警到消防泵正常供水的時間不大于5min，這個時間包含了管理人員從控制室到泵房的時間以及包括消防泵從強制啟動到正常供水的時間)。

According to article 11.0.12 of technical code for fire water supply and hydrant system (gb50974-2014, this article is mandatoryPressure start, remote start and hard pull start are all realized by relay. lf the relay and weak curent signal fail to start the fire pumpautomatically, the "mechanical emergency start device" set in the fire pump control cabinet shall be used directly Start the fire pump.When the weak curent signal and the hardwire start-up relay fail, and the secondary circuit and electrical equipment fall in the fire pumpconrol cabinet, the tre pump cannot be started automatically or manualy. Therefore, in case of fire emergency, this article stipulates thathe fire oump can be started direcily under normal power supoly, no malter how the control circuit in the fire pump control cabinet isdamaged, so as to ensure the fire Fire fighting timeliness, the "mechanical emergency starting device’is directly driven by themechanical interlock device to realize the direct start of the fire pump. The device can be configured with star delta star and sot startThe starting handle of 'mechanical emergency starting device"is in the stop state (with lock) at ordinary times. In case of emergency fireit must be operated by the authorized management personnel (mechanical emergency starting device with lock, usually kept by theauthorized person, and the time from the alarm to the normal water supply of the fire pump is not more than 5min, which includes the timerom the control room to the pump room and the time from the management personnel to the pump room as well as the time from the irepump room Time from forced start to normal water supply).
