Fire pump automatic inspection control cabinet, also known as fire intelligent digital inspection device. This device can prevent faults such as corrosion, humidity, and abnormal pump movement of the fire pump, and indeed achieve the goal of thousands of days. In the construction of Fire protection engineering, fire inspection cabinet plays an important role in ensuring fire safety management and realizing safe operation of * *. So, what is the function of the fire inspection cabinet? 1、 Intelligent fire inspection is necessary. Fire water supply equipment is an important component of the fire protection system, whether it is a fire linkage alarm system or various automatic fire control equipment to judge disasters until they alarm, and ultimately start the fire pump and fire control cabinet as one of the fundamental purposes. There is a common problem with various fire water supply equipment nowadays: in building fires, a considerable number of fire pumps cannot start after receiving a start signal, delaying fire opportunities, causing huge losses to national property and people's safety. The main reason is that the fire pump does not start, and most enterprises purchase fire pumps that are not made of stainless steel material. Over time, in the humid environment of the pump room, the internal pump shaft, impeller, and The phenomenon of shaft sleeve rust death. Given the above situation, it is necessary to conduct regular inspections of the fire pump and control cabinet to maintain the mechanical performance of the fire pump and the performance of the electrical control cabinet, always in good condition. This inspection method can fundamentally solve the serious consequences of rust on the fire pump. To address the implementation of fire water supply equipment and the implementation of fire water supply equipment. According to the Fire Safety Industry Standard GA30.2 "Performance Requirements and Test Methods for Fixed Fire Water Supply Equipment" of the Ministry of Public Security, in order to prevent faults such as corrosion, moisture, and abnormal pump movement of fire water pumps, automatic inspection devices must be installed on fire water pumps. The inspection is a low-frequency inspection, with a motor speed of 300 rpm. The water system is not pressurized and has no starting current, greatly extending the service life of the equipment. This inspection method has high safety, low current, and low power consumption, and is a standard inspection method that meets the requirements of the Ministry of Public Security industry.

Fire pump automatic inspection control cabinet, also known as fire intelligent digital inspection device. This device can prevent faults such as corrosion, moisture, and abnormal pump operation of the fire pump, and has indeed achieved the goal of thousands of days. Intelligent fire inspection cabinets are mainly used in large shopping centers, residential areas, and crowded places. According to relevant national regulations, fire safety facilities and equipment must be installed in crowded areas. The installation of fire inspection cabinets is to prevent sprouts and stories, and truly reflect their role. The following are several issues that should be noted when installing fire inspection cabinets: 1. The equipment should not be installed in damp places, and should be installed in ventilated areas as much as possible, and equipped with fans to help dehumidify. 2. The power supply line should be laid in an empty trunking, which is beneficial for later maintenance. 3. Install by professional installation personnel to avoid product and personnel damage. 4. After equipment installation, check if the circuit is grounded and if lightning protection is in place. 5. Equipment maintenance should be dismantled and replaced under the guidance of professional personnel. Its main product, the fire inspection cabinet, has passed the new national 3C standard certification and test report, ensuring that users are not hindered during the acceptance process. At the same time, it also ensures that our products pass national standards and the quality of our products is more reliable. The fire inspection equipment consists of two parts: main circuit inspection and non pressure inspection of fire equipment, which can complete low-speed automatic inspection of the main control circuit and water pump. When there is no fire command in the system and the switches of each fire control equipment system are in the automatic state, automatic inspection and operation of the fire pump can be carried out. The automatic inspection cycle is optional from several hours to hundreds of hours, and the cycle clock automatically starts the inspection program and has a manual inspection function. The fire intelligent digital inspection equipment outputs inspection instructions to inspect the main circuit one by one, and the inspection return signal is taken from the main auxiliary contacts of each electrical component. The allowable value of feedback signal time shall not exceed 2 seconds. After the main circuit inspection is completed, the inspection controller will send the next inspection command to the pressure free inspection device. After receiving the inspection command, the device will sequentially conduct low speed pressure free inspection on the fire water pump. During the inspection, the motor speed is low and the system does not generate water pressure. During the inspection, the driving power of the fire pump is very small, about one percent of the rated power of the pump motor, so the energy saving is significant. During the entire inspection process, if the equipment receives a fire command, the intelligent inspection controller will immediately issue a command to stop the inspection and start the fire pump to complete the fire task. Only when there are no fire incidents during the next inspection cycle can a new inspection run begin. During inspection, if the water pump malfunctions, a fault alarm message will be given. When input overvoltage, undervoltage, phase loss, output overcurrent, or short circuit occurs, the controller will send an alarm message to the fire center. The results of this automatic inspection can ensure that the fire water pump will not rust or die, making it a reality for the fire water supply equipment to "maintain soldiers for a thousand days, and use them for a while". This equipment also has automatic exchange of main and backup pumps, and when the main pump fails, the backup pump will automatically be put into operation; The main and backup power supplies automatically switch on each other, and when the main power supply fails, the backup power supply will automatically switch on and other functions; The digital intelligent fire inspection and control equipment will provide functions such as data remote transmission, image monitoring, fault alarm, and information printing for all the above functions.

Control method. The fire inspection cabinet automatically starts the fire pump at low speed and without pressure according to the set time cycle, and checks whether the electrical function of the control cabinet is normal. The fire control cabinet is a manual/automatic full power start fire pump, which can be divided into star delta start, direct start, self coupling step-down start, and soft start. In terms of working hours. When a fire does not occur, the fire inspection cabinet belongs to the regular inspection of the working status of the fire pump. Once a fire occurs, the inspection function automatically stops and the fire pump runs at full pressure. When a fire occurs, the fire control cabinet receives a start signal from the fire control center, starts the sprinkler system and the fire pump of the fire hydrant, achieving the goal of eliminating and controlling the fire. That is to say, the fire inspection cabinet is a guarantee for the normal operation of the fire control cabinet, fire prevention and control cabinet, and fire pump, both of which are indispensable. Functionally speaking, the fire inspection cabinet, as the name suggests, is an automatic inspection of the fire equipment - fire pump, which means regularly checking the working status of the fire pump. Once the pump is found to be working abnormally during the inspection process and cannot work properly, an alarm signal is immediately sent to record the type of fault, facilitating maintenance personnel to handle the fault in a timely manner and ensuring that the fire pump plays a role in a fire. The general inspection time can be manually set according to the actual situation. The fire control cabinet is mainly used to control the start and stop of fire pumps and Fire hydrant. In case of fire, receive the fire signal from the fire control center, start the corresponding fire pump and Fire hydrant, and control and eliminate the fire in time.
