1. Function of installation and management of electromechanical fire fighting equipment

In construction engineering, fire protection system is a necessary functional system. Its function is to ensure the safety of users and building environment and prolong the service life of buildings. Mechanization has become the mainstream trend in the environment of the construction industry. Strengthening the installation of electromechanical equipment of fire protection system can not only comply with the macro development, but also ensure the function of fire protection system and comprehensively and concretely cover the fire protection function. The operation environment of this process is changeable and cumbersome, and there are operation risks. If you want to do a good job in the installation of electromechanical management, you need to implement standardized construction to ensure the quality of the fire protection system. The construction unit shall establish the concept of integrated management, establish the installation content and strengthen the construction control.

2 key points of electromechanical fire protection engineering installation project

2.1 electromechanical fire protection technology of Construction Engineering

The electromechanical fire protection construction of construction engineering is highly professional, has a large practical operation surface, and the construction route is long, which often has tight requirements on the construction period. Moreover, in the specific construction, there are many factors that will affect it, so it is necessary to well coordinate the work between the project participants. Therefore, the quality control is very difficult. The key points of the construction are mainly the automatic fire alarm system engineering, the quality control of the temperature sensing optical fiber fire detection and alarm system engineering, the construction of the water spray fire extinguishing system, the relationship between the fire fighting system in the comprehensive electromechanical engineering, the debugging of the fire fighting system, and the comprehensive debugging of the system.

2.2 fire protection management of building electromechanical engineering construction

In the construction of mechanical and electrical engineering, the key points of fire management are mainly to carry out fire safety education and training for employees. As many employees are migrant workers, they are highly mobile, lack professional training and lack knowledge of fire prevention and self rescue. Therefore, in the fire management, it is necessary to pay attention to the fire safety training of employees, focus on checking the ability and fire awareness of relevant personnel, and ensure that their technical level meets the relevant requirements of the project. For example, during the welder operation, the operation shall be carried out according to the specifications, and the operation safety shall be effectively controlled to avoid fire during construction. At the same time, the self rescue ability of employees shall be improved, and the safety management shall be run through the construction to ensure the implementation of effective fire system management and improve the construction efficiency. In personnel recruitment, we should also strengthen control, strengthen fire safety education and training, establish a clear fire emergency management mechanism and enhance the management effect.

Establish fire and power management specifications to realize standardized management of actual construction, do a good job in fire safety and avoid possible fire accidents. Electric welding, power connection and other operations that need to be carried out during construction are dangerous. Therefore, the hot work approval system shall be strictly implemented and handled by professionals to ensure that the distance between fire source and combustibles is safe enough and completely remove the potential fire hazard. In addition, attention should be paid to the combustibles and building materials on the construction site in its management. The materials with fire risk must be stored and kept separately. At the same time, fire-fighting equipment should be configured, fire hydrants should be set reasonably, and maintenance should be paid to ensure that they can be put out in time after an accidental fire and avoid greater losses.

3 management measures for installation of electromechanical fire protection works

3.1 fundamentally ensure the effective application and benign operation of intelligent automatic control system

In the process of promoting the installation project of electromechanical fire protection engineering, it is necessary to keep pace with the times and further effectively set up the corresponding intelligent automatic control system. Only the stable operation of this automatic and intelligent system can fundamentally ensure the automatic fire alarm, realize the automatic control of fire protection equipment, and make the intelligent system show its due application value. In the specific implementation process, the intelligent automatic control system should be continuously optimized and improved to ensure the normal operation of automatic fire alarm and automatic control system of fire equipment. When optimizing the intelligent automatic control system, relevant influencing factors shall be considered. The intelligent system has integrated wiring, communication, alarm and other related functions. Only by ensuring that the performance of relevant components reaches the optimal standard and meets the most ideal operating conditions, can it have higher sensitivity to temperature and timely and effective induction against fire hazards or potential risks, Send out corresponding alarm and inform residents to evacuate in time and effectively at the first time. After the fire alarm system is networked with the computer system, it can more quickly and effectively transmit relevant information, so as to ensure that relevant firefighters can timely and effectively master the operation of building electromechanical equipment and deal with it at the first time.

3.2 fundamentally and effectively do a good job in the quality monitoring of temperature sensing optical fiber fire detection and alarm system project

The fire alarm control computer is connected to the fire alarm controller to collect the fire alarm signal. The linear optical fiber temperature detection system is used as the fire detection system in the comprehensive pipe trench. The temperature sensing optical fiber is led out by the system processor and laid on the top of the pipe warehouse of each pipe trench; In the power warehouse, the contact snake is arranged on the power cable tray on each floor. Through this method, if you encounter relevant fire hazards, you can respond at the first time and give an alarm in time, so that you can deal with the fire more timely and effectively, and improve the fire rescue effect most significantly.

3.3 do a good job in the supervision of electromechanical installation and fire protection works

As the linear optical fiber temperature sensing fire detection system has particularly strict requirements for the material quality and installation quality of optical fiber, it is necessary to focus on the control and control of relevant materials, and carry out strict and detailed testing and trial operation to ensure that it can be put into use after it is safe. In the whole process, we should focus on the following aspects: first, we should fundamentally and effectively review the qualification of relevant materials. During the review and control of materials, the quality assurance certificate shall be strictly inspected, and corresponding test reports and quality assurance documents shall be provided. Secondly, the materials must have the manufacturer's batch number and factory certificate, and the sampling inspection shall be carried out according to the regulations. In such a case, the contractor needs to conduct in-depth analysis and research, and take practical measures to deal with them. After the treatment, it can be applied only after passing the verification. Third, for materials with unclear marks or suspected quality problems, and relevant materials with suspected quality assurance data or inconsistent with the provisions of the contract, sampling tests shall be carried out in strict accordance with the relevant proportion. It can only be applied after experimental demonstration. Fourth, the methods of material quality sampling and inspection should fully comply with the relevant national regulations and quality specifications. At the same time, in the process of its application and management, it should also comply with the established processes and standards.

3.4 optimize the water spray fire extinguishing system.

The quality control of water spray fire extinguishing system should be carried out on a single power test run one by one, such as detector, alarm controller, fire alarm device and fire control equipment. (1) Focus on the preparation before commissioning: A. when the commissioning scheme is determined, the corresponding commissioning team shall be established, and the members of the commissioning team mainly include the owner, construction, supervision, fire department, etc. b. The water volume reserved in the fire pool shall meet the corresponding design requirements and ensure the normal power supply. c. The water level and air pressure of pneumatic water supply equipment meet the design requirements. D. water spray system pipe network has been filled with water, valves are not leaking. (2) Do a good job of water source test: during the test, strictly check whether the volume of the fire pool really meets the relevant design requirements and quality specifications, whether the fire water is used for other purposes, whether the relevant technical measures are prepared in place, and whether it is scientific and feasible enough. (3) Commissioning of fire pump: A. start the fire pump automatically or manually, and the pump shall be put into normal operation within 5min. b. When switching with standby power supply, the fire pump shall be put into normal operation within 1.5min. (4) Commissioning of stabilized pressure pump: simulate the design starting conditions, and the stabilized pressure pump shall be started immediately. When the system design pressure is reached, the stabilized pressure pump can automatically stop running at the first time.

3.5 strengthen construction quality control

The construction electromechanical installation and fire protection project itself involves a large workload in the construction process. Therefore, in order to effectively ensure the construction quality, it is necessary to strengthen the comprehensive control of the quality of each process, implement the concept of multi integration, and implement the quality control measures in many links such as supervision, inspection and testing. First of all, the quality management system formulated in advance should be strictly implemented to ensure the effectiveness of supervision. Secondly, during the formal construction, it is often faced with some unexpected accidents that are difficult to achieve prediction. Based on this, the quality control personnel must take scientific and reasonable response measures in advance, update and supplement the quality control standards in combination with the changes of the actual situation, and control the damage caused by safety risks to the project to the greatest extent. At the same time, in the process of construction quality control, we should optimize the selection of technology based on the basic situation of the project, and ensure that the construction technology can meet the standards of quality control. Finally, construction enterprises should optimize and improve the scientificity of their internal structure on the original basis, and actively introduce various advanced quality control concepts and technologies, so as to improve the modernization of engineering construction.
