First, the need for fire inspection under the provisions of the Ministry of Public Fire Safety industry standard GA30.2 "fixed fire water supply equipment performance requirements and test methods", in order to prevent the fire pump corrosion, moisture, water pump action is not normal fault, really do to the "idea that day, military forces while" purposes, fire pumps must be installed automatic inspection equipment. Inspection for low-inspection, inspection when the motor speed of 300 rev / min, the water system is not pressurized, no start-up current, greatly extending the life of the equipment. This inspection safe mode, low current, low power consumption, is the only way to meet the Ministry of Public Security inspection industry standards. Second, fire inspection equipment performance ☆ has interactive features, dialogue circles for localization, chart a clear and easy to identify, easy to operate. ☆ using computer control technology, leading technology and high security. ☆ can detect power voltage, over-voltage, under-current, over-current, phase. ☆ has overload, short circuit, start abnormal and fault alarm function; ☆ store GA30.2 failure to meet several criteria, can store more than 150 fault information recorded ☆ low frequency low-speed automatic inspection function to ensure the fire pump does not rust.; ☆ received the Fire Patrol command will stop instantly start the fire pump inspection;. ☆ Fire fire pump by way of by-station up and running, each pump running time of less than two minutes ☆ fault should sound patrol found, light alarm. Device with fault memory function, record time fault type and fault occurs, should not less than five fault information, which should be clear and understandable display. ☆ Fire pump frequency inverter run when equipment fails, the fire alarm in case of fire pump shall be automatically transferred into the fire-frequency mode. ☆ inspection period and inspection time can be set as needed, to meet the needs of the site. ☆ equipment should have automatic and manual inspection functions, the automatic inspection period should be set on demand. ☆ meet fire safety requirements, has a complete fire interface. ☆ a host telephone alarm. ☆ equipment earmarked RS485 communication interface, to be completed on the operational status of remote building automation. ☆ a fault parameters when logging printing. . Third, the digital intelligent automatic inspection equipment Features a fire control, fire control cabinet automatic inspection fuzzy logic control program to achieve a unique design approach to automatic inspection, the fire pump running regularly, avoid rust phenomenon. Energy consumption 2, with no low-pressure automatic inspection techniques, fire inspection when not pressurized water distribution network, can be arbitrarily set automatic inspection cycle, from several hours to several hundred hours fire pump inspection, while fire inspection only about 2% of the rated power. Fire inspection control cabinet operates in the fire run mode, with anti-overpressure device, when the fire occurred, fire automatic inspection control cabinet immediately terminate the inspection to the pump frequency start, if the main pump fails, automatically open standby pump. 3, fire inspection control cabinet with the fire center networking, but also realize remote fire inspection data, fire inspection remote control?, Fire inspection can be achieved in hot standby dual control system (optional) or remote system status computer real-time image display. 4, fire inspection counters can simulate the fire to test the water. To achieve the fire test water features, fire pump test water pipes to be installed in charge of the road path, each test water on the road according to the pressure sensor fitted with one or two-way flow transmitter and electric butterfly valve, all of the feedback signal access Patrol cabinet The control unit. When the patrol inspection cabinet pumps, five seconds ahead of each solenoid valve opens, followed by inspection of pumps, when the actual monitoring pipeline pressure and flow. Pump inspection is completed, the solenoid valve closure delayed five seconds. If the overpressure or water pipe inspection process occurs automatically stop the patrol, concurrent sound and light alarm, alarm information timely to reflect on the inspection interface After troubleshooting, pump set time automatic inspection and test water.
