Fire pump controller with fire pump electric control start and mechanical emergent start

Abstract

The invention relates to a fire pump controller with fire pump electric control start and mechanical emergent start. The fire pump controller comprises a control cabinet body; a self-start locking control switch and a remote control locking control switch are arranged in the lower part of the cabinet body; a PLC is arranged in the control cabinet body; two sets of normal-operated star triangle start operation units are additionally arranged in the control cabinet body for respectively controlling two fire pump motors; two sets of emergent start devices are mounted in the control cabinet body for respectively controlling two fire pump motors; correspondingly, unlocking operation handles with quick energy storage mechanisms are arranged on the emergent start devices; and a main stop button is arranged on a cabinet body panel. The fire pump controller can solve the problem of delay of fire rescue due to incapability of starting a traditional fire pump when a control circuit breaks down, can guarantee the emergent start devices to forcedly start the equipment as long as normal power supply of the fire pump is realized under any conditions of the control circuit, and accords with the regulations of GB50974-2014 Fire Water Supply and Hydrant System Technical Specification.

Description

technical field [0001] The invention relates to a water pump controller, more specifically to a fire water pump controller equipped with electric control start and mechanical emergency start of the fire water pump. Background technique [0002] The fire pump is the key link of the fire water fire extinguishing system, and its operation reliability is required to be high. Especially in the past ten years, urban construction has advanced by leaps and bounds, there are more and more super high-rise buildings, and the living masks are becoming more and more compact, which puts forward higher requirements for the reliability of the fire water fire extinguishing system. [0003] At present, the fire-fighting water pumps in the prior art generally adopt electronically controlled starts such as full-voltage start, soft start, star-delta step-down start, auto-coupling step-down start, and the like. There are many nodes in the electric control start control line, and it is inevitable...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to aim at the above-mentioned defects of the prior art, to provide a fire-fighting water pump controller equipped with fire-fighting water pump electric control start and mechanical emergency start-up, which can solve the problem that the fire-fighting water pump cannot start when the control line fails, and delays The difficulty of fire rescue; as long as the power supply of the fire pump is normal, the emergency start device can be guaranteed to start the equipment regardless of the control circuit, which meets the requirements of GB50974→2014 "Technical Specifications for Fire Water Supply and Fire Hydrant Systems"
