Abstract

The invention discloses automatic routing inspection control equipment for a fire pump and an electrical control circuit of the automatic routing inspection control equipment, and belong to the fieldof fire-fighting electrical control devices. The electrical control circuit of the automatic routing inspection control equipment is used for carrying out automatic routing inspection control on the fire pump, and comprise a switching circuit, a main loop, a PLC control loop, a fire-fighting linkage control loop and an indication loop; the main loop is connected with the PLC control loop and the indication loop, and the PLC control loop is connected with the fire-fighting linkage control loop; the automatic fire pump routing inspection control equipment based on the circuit comprises a routinginspection cabinet and a fire-fighting power distribution cabinet which are connected with each other; the PLC control loop controls a working circuit for routing inspection of the main loop and supplies power to the detected fire pump at low frequency, so that the fire pump operates at low speed according to a set period, and automatic routing inspection of the fire pump is realized; and the problems that the control cabinet and the routing inspection cabinet of existing automatic routing inspection control equipment are difficult to realize better electrical interlocking, the control switching is slow, the control circuit is complex, and the control reliability is reduced can be solved.

Description

technical field [0001] The invention belongs to the field of fire-fighting electrical control devices, and relates to a fire-fighting pump automatic inspection control device and an electrical control circuit thereof. Background technique [0002] According to the Ministry of Public Security's fire safety industry standard GA30.2 "Performance Requirements and Test Methods for Fixed Fire Water Supply Equipment", in order to prevent fire pumps from rusting, damp, and abnormal pump actions, it is true that "raise soldiers for thousands of days, use soldiers For the purpose of "temporary", fire pumps must be equipped with automatic inspection devices, especially for fire pumps in the fire system of enterprises and institutions, daily inspections should be done. [0003] Therefore, the daily inspection of the fire pump of the fire protection system is particularly important, but there are still some problems in the current automatic inspection control equipment of the fire pump, ...
