The mutual use of fire inspection cabinets and pump startup cabinets

According to the GA30.2 “Requirements and Test Methods for the Performance of Fixed Fire Water Supply Equipment” issued by the Ministry of Public Security’s Fire Safety Standard, in order to prevent the fire pumps from being corroded, dampened, and malfunctioning of the pump, it is true that “one day of military service and one hour of military service For the purpose of fire-fighting pumps, an automatic inspection device must be installed. The patrol inspection is a low-frequency patrol. During the patrol inspection, the motor speed is 300 rpm, the water system is not pressurized and there is no starting current, which greatly prolongs the service life of the equipment. This patrol method has high safety, low current, and low power consumption. It is an inspection method that meets the standards of the Ministry of Public Security.
one. Automatic patrol device control function: complete low-speed and spray pump low-speed self-service inspection control for fire pump, spray pump, inspection cycle 24 hours, each inspection single pump inspection time is 10 minutes, inspection cycle and The inspection time can also be arbitrarily adjusted from minutes to days according to actual requirements. When a fire occurs, the programmable controller will automatically stop the inspection after receiving the fire command, start the fire pump, and the fire end will be manually shut down.
two. The device has sound and light alarms and fault memory function. The operation is easy to understand the Chinese menu, can remember short circuit, phase loss, over current, over voltage, under voltage, communication and other faults to facilitate the operation and maintenance personnel.
III. Performance description of fire intelligent digital inspection device HX-FC fire intelligent digital inspection device is a third-generation fire automatic inspection device independently developed by our company. The equipment has two parts: main circuit inspection and fire-fighting equipment pressureless inspection. The composition can complete the low-frequency automatic inspection of the main control circuit and the water pump, and the system is not pressurized during the inspection. During the inspection, the intelligent inspection controller outputs the instructions, and the intelligent inspection controller outputs inspection instructions to perform inspections on the main loop contactors one by one. The inspection return signal is taken from the main auxiliary contact of the contactor. The allowable value of feedback signal time is not greater than 2S. After the inspection of the main circuit is completed, the inspection controller will generate the next inspection instruction to the non-pressure inspection device. After receiving the inspection instruction, the device will in turn perform the low-speed and pressure-free inspection of the fire pump. During the inspection, the motor speed is low and the system does not generate water pressure. During the entire inspection process, if the equipment receives a fire inspection command, the intelligent inspection controller will immediately issue an order to stop the inspection and instantly start the fire pump to complete the fire protection task. If the movement during the inspection is abnormal, the controller will record the number of the faulted branch and the type of fault, and issue an audible and visual alarm. At the same time complete the upload of the failure (can be transmitted to the fire control room or building control duty room) notify the on-duty personnel to carry out maintenance, to ensure that the fire fighting equipment is foolproof.
Fourth, fire intelligent digital inspection device features
1. During the inspection, the fire will immediately stop the inspection and start the fire pump instantaneously.
2. Complete functions can complete the fire main loop and fire pump low-speed pressure-free inspection.
3. With over-voltage, over-current, short-circuit, missing equal protection.
4. During the inspection, a fault occurs in the automatic inspection device. The sound and light alarm occurs. The data memory function can complete the transient parameter memory during faults, which is convenient for maintenance and analysis.
5. The inspection running parameters can be displayed through the interface. (optional)
6. With superior telephone alarm function. (optional)
7. The RS485 communication interface is reserved for the device, which can complete the remote transmission of the automatic control of the building. (optional)
8. It has fault parameter printing function during inspection. (optional)
