The operation of fire automation installations is understood as their use for detecting or extinguishing fires, as well as their maintenance and repair. When operating AUP, APS, a set of measures is carried out that provide: technically correct use installations, i.e. application when detecting or extinguishing a fire, in extinguishing mode; correct storage; timely and high-quality maintenance in order to maintain the unit in good and efficient condition; timely and high-quality repairs; Maintenance is understood as a set of works that provides control technical condition, extending the service life. Maintenance activities are divided into four groups: preparation of the installation for use after operation or repair, including refueling and loading operations (replacement of triggered or damaged sprinklers, etc.); control of technical condition; prevention; current repairs in order to maintain the reliability and durability of installations. Monitoring of the technical condition is carried out in order to assess the ability of installations to perform specified functions. This ability is evaluated by the values of certain parameters. If the values of these parameters correspond to the rated values, the installation is considered to be in good working order. In case of deviation from the norms, the installation is faulty, because it cannot provide satisfactory performance given functions... Thus, monitoring the state of installations is reduced to compiling true ones, i.e. measured at the installation, values, parameters with their nominal values. As a result of the comparison, a conclusion is made about the technical condition of the installation and the possibility of its further use. Maintenance is divided into daily, monthly, quarterly, and annual. With daily maintenance, the following scope of work is carried out: monitoring the state of the pipeline painting; control over adherence to permissible distances (no more than two meters) from sprinklers to stored materials; external examination of control units (control and launch units, valves); check on pressure gauges above and below the control and launch unit (the difference should not exceed 0.05); operation of pumps, compressor in accordance with the instructions (passports) of the manufacturers. The results of the inspection for each item are recorded in the log book "plant operation". With monthly maintenance, daily maintenance work is carried out, as well as the following operations: inspection and maintenance work related to the electrical equipment of installations; checking the voltage of the main and backup power supplies, inputs to automatic switches, inputs of automatic switches in the signaling circuit; checking the performance of electrical circuits in remote and automatic modes; inspection and preventive work on all communications of installations check of pumps and its fittings, pressure - according to the readings of manometers; check of control and starting devices. Quarterly maintenance includes monthly maintenance operations, in addition, the following works are performed: checking the condition and fastening of the pipeline and sprinklers; checking the work of ЭКМ according to the control pressure gauge; turning the shafts of the electric motors of the pumps by hand. The annual includes measures for quarterly maintenance and in addition to this: tightness test of check valves and gate valves; inspection and examination of instrumentation within the time frame specified in the factory instructions; replacement or repair of worn parts; random check of sprinkler fluid loss; measurement of the resistance of the ground loop. In addition, there are maintenance jobs that must be performed every 3 years. These include: annual maintenance operations; elimination of leaks in the system, repair of equipment fasteners; tinting equipment; repair of grounding devices; measurement of drive insulation of installations; revision of pumps, valves; flushing the system. INSTRUCTIONS FOR USE AUP. GENERAL INSTRUCTIONS Acceptance of AUP into operation should be carried out by representatives of: energy companies (chairman); design, installation and commissioning organizations; state fire supervision. The commission's work program and acceptance certificate must be approved by the chief technical manager of the enterprise. SECURITY MEASURES When operating the technological equipment of water fire extinguishing installations, the personnel of power companies must comply with the relevant safety requirements specified in the PTE, PTB, as well as in the factory passports and operating instructions for specific equipment. During the maintenance and repair of the AUP, when visiting the premises protected by the AUP, the automatic control of a particular distribution pipeline in this direction should be switched to manual (remote) until the last person leaves the room. Pressure testing of pipelines with water should be carried out only according to an approved program, which should include measures to ensure the protection of personnel from a possible rupture of pipelines. Ensure complete removal of air from pipelines. It is prohibited to combine crimping work with other work in the same room. If the pressure testing is carried out by contractors, then the work is carried out according to the permit. The performance of these works by the operational or repair personnel of the power company is documented in a written order. Before starting work, personnel involved in pressure testing must be instructed in workplace safety. During crimping, no unauthorized persons should be in the room. Pressure testing must be carried out under the supervision of a responsible person. Repair work on the technological equipment should be carried out after the pressure is removed from this equipment and the preparation of the necessary organizational and technical measures established by the existing PTB. PREPARATION FOR WORK AND CHECKING THE TECHNICAL CONDITION FIRE EXTINGUISHING UNITS The foam fire extinguishing installation consists of: a source of foam supply (reservoir); fire pumps (designed for intake and supply of solution to pressure pipelines); suction pipelines (connecting the water source with fire pumps); pressure pipelines (from the pump to the control unit); distribution pipelines (laid within the protected premises); control units installed at the end of pressure pipelines; sprinklers. In addition to the above, based on design solutions, the following can be included in the fire extinguishing installations scheme: a tank with a foam concentrate solution for filling fire pumps; pneumatic tank for maintaining constant pressure in the network of the fire extinguishing installation; a compressor for feeding the pneumatic tank with air; drain taps; check valves; dosage washers; pressure switch; manometers; vacuum gauges; level gauges for measuring the level in tanks and a pneumatic tank; other signaling, control and automation devices. After the completion of the installation work, the suction, pressure and distribution pipelines must be flushed and subjected to hydraulic tests. The results of flushing and pressure testing must be documented. If possible, the effectiveness of the fire extinguishing installation should be checked by organizing the extinguishing of an artificial fire source. When flushing pipelines, water should be supplied from their ends towards the control units (in order to prevent clogging of pipes with a smaller diameter) at a speed 15-20% higher than the solution speed in case of fire (determined by calculation or recommendations of design organizations). Flushing should be continued until clean water is consistently produced. If it is impossible to flush individual sections of pipelines, it is allowed to blow them with dry, clean, compressed air or inert gas. Hydraulic testing of pipelines must be carried out under a pressure equal to 1.25 working pressure (P), but not less than P + 0.3 MPa, for 10 minutes. To disconnect the tested section from the rest of the network, it is necessary to install blind flanges or plugs. It is not allowed to use for this purpose the existing control units, repair valves, etc. After 10 minutes of testing, the pressure should be gradually reduced to working pressure and a thorough inspection of all welded joints and adjacent areas should be performed. The pipeline network is considered to have passed the hydraulic test if no signs of rupture, leaks and drops in welded joints and on the base metal, visible permanent deformations are found. The pressure should be measured with two pressure gauges. Flushing and hydraulic testing of pipelines should be carried out under conditions that exclude their freezing. It is prohibited to backfill open trenches with pipelines exposed to severe frosts, or backfill such trenches with frozen soil. Automatic water fire extinguishing installations must operate in the automatic start mode. For the period when personnel are in cable facilities (bypass, repair work, etc.), the start-up of installations should be switched to manual (remote) switching. MAINTENANCE OF FIRE-FIGHTING UNITS Persons responsible for the operation, overhaul and current repairs of the technological equipment of the fire extinguishing installation are appointed by the head of the energy company, who also approves the schedules for technical supervision and equipment repair. The person responsible for the constant readiness of the technological equipment of the fire extinguishing installation must know well the principle of the device and the procedure for the operation of this equipment, and also have the following documentation: project with changes made during the installation and commissioning of the fire extinguishing installation; factory passports and operating instructions for equipment and devices; this Model Instruction and local operating instructions for process equipment; acts and protocols of installation and commissioning works, as well as testing of technological equipment; schedules of maintenance and repair of technological equipment; "Log book for the maintenance and repair of the fire extinguishing installation." Any deviations from the scheme adopted by the project, replacement of equipment, additional installation of sprinklers or their replacement with sprinklers with a large nozzle diameter must be previously agreed with the design institute - the author of the project. To monitor the technical condition of the technological equipment of the fire extinguishing installation, a "Register of maintenance and repair of the fire extinguishing installation" should be kept, which should record the date and time of the inspection, who carried out the inspection, the detected faults, their nature and time of their elimination, the time of forced shutdown and activation fire extinguishing installations, carried out by testing the operation of the entire installation or individual equipment. At least once a quarter, the chief technical manager of the enterprise must familiarize himself with the contents of the journal on receipt. To check the readiness and efficiency of the AUVP, a complete audit of the technological equipment of this installation should be carried out once every three years. During the audit, in addition to the main work, pressure testing of the pressure pipeline is carried out and flushing (or purging) and pressure testing of distribution pipelines located in the most aggressive environment (dampness, gas pollution, dust) are carried out in two or three directions. If deficiencies are found, it is necessary to develop measures to ensure their complete elimination in a short time. An automatic fire extinguishing installation in accordance with the schedule approved by the head of the relevant workshop, but at least once every three years, must be tested (tested) according to a specially developed program with the actual start-up of them, provided that this does not entail a shutdown of the technological equipment or all the production process. During testing on the first and last sprinklers, the water pressure and irrigation intensity should be checked. Testing should be carried out with a duration of 1.5-2 minutes with the inclusion of serviceable drainage devices. Based on the results of testing, an act or protocol must be drawn up, and the fact of testing itself must be registered in the "Journal of maintenance and repair of the fire extinguishing installation". Checking the operation of AUVP or certain types of equipment should be carried out during the withdrawal for repair, maintenance of the protected premises and the technological unit. For storage of spare equipment, equipment parts, as well as fixtures, tools, materials, devices necessary for the control and organization of repair work of AUVP, a special room should be allocated. The technical capabilities of AUVP should be included in the operational plan for extinguishing a fire at a given power plant. During firefighting trainings, it is necessary to expand the circle of personnel who know the purpose and device of the AUVP, as well as the procedure for activating it. The personnel servicing the AUVP compressors and pneumatic tanks must be trained and certified in accordance with the requirements of the Gosgortekhnadzor rules. The person responsible for the operation of the technological equipment of the fire extinguishing installation must organize training with personnel assigned to control the operation and maintenance of this equipment. In the room of the AUVP pumping station, the following should be posted: instructions on how to turn on the pumps and open the shut-off valves, as well as basic and technological diagrams. The entrances to the building (room) of the pumping station and the fire extinguishing installation, as well as the approaches to the pumps, pneumatic tank, compressor, control units, pressure gauges and other equipment of the fire extinguishing installation, must always be free. On an operating fire extinguishing installation, the following must be sealed in working position: hatches of reservoirs and tanks for storing water supplies; control units, gate valves and manual cranes; pressure switch; drain taps. After the fire extinguishing installation is triggered, its operability must be fully restored not after 24 hours. Checking the water level in the tank should be carried out daily with registration in the "Log book of maintenance and repair of the fire extinguishing installation." The correct operation of the automatic level gauge in the tank should be checked at least once every three months at positive temperatures, monthly - at negative temperatures and immediately in case of doubts about the correct operation of the level gauge. The tanks must be closed for unauthorized access and sealed, the integrity of the seal is checked during the inspection of the equipment, but at least once a quarter. The water in the tank should not contain mechanical impurities that could clog pipelines, metering washers and sprinklers. To prevent decay and blooming of water, it is recommended to disinfect it with bleach at the rate of 100 g of lime per 1 m of water. Replace the water in the tank annually at autumn time... When changing the water, the bottom and inner walls of the tank are cleaned of dirt and build-up, the damaged paint is restored or completely renewed. Before the onset of frost near buried tanks, the gap between the upper and lower hatch covers must be filled with insulating material. Once a quarter, the condition of the bushings, shut-off valves, measuring instruments and the water intake well is checked. Before the onset of frost, the fittings in the water intake well must be inspected, repaired if necessary, and the well must be insulated. Before testing the pumps it is necessary to check: the tightening of the oil seals; the level of lubrication in the bearing tubs; correct tightening of foundation bolts, pump cover nuts and bearings; suction-side piping connections and the pumps themselves. Once a month, pumps and other equipment of the pumping station should be inspected, cleaned of dust and dirt. Each fire pump must be turned on at least twice a month to create the required pressure, which is recorded in the operational log. At least once a month, the reliability of the transfer of all fire pumps to the main and reserve power supply should be checked with the registration of the results in the operational log. If there is a special tank for filling the pumps with water, the latter must be inspected and painted annually. Once every three years, pumps and motors, in accordance with clause 5.1.5 of this Standard Instruction, must undergo an audit, during which all existing deficiencies are eliminated. Repair and replacement of worn out parts, check of oil seals are carried out as necessary. The pumping station must be kept clean. In the absence of duty, it must be locked. One of the spare keys must be kept on the control panel, which must be indicated on the door. Once a quarter, it is necessary to check: absence of leaks and deflections of pipelines; the presence of a constant slope (not less than 0.01 for pipes with a diameter of up to 50 mm and 0.005 for pipes with a diameter of 50 mm and more); condition of pipeline fasteners; lack of contact with electric wires and cables; condition of painting, absence of dirt and dust. Discovered deficiencies that could affect the reliability of the installation should be eliminated immediately. The pressure pipeline must be constantly ready for action, i.e. filled with water and under operating pressure. For AUP of transformers and cable structures in locking and starting devices, steel fittings, electrified valves with automatic start of grade 30s 941nzh should be used; 30s 986nzh; 30s 996nzh with a working pressure of 1.6 MPa, repair valves with manual drive grade 30s 41nzh with a working pressure of 1.6 MPa. The state of the control units and valves, the presence of a seal, the pressure values before and after the control units must be monitored at least once a month. Once every six months, the electrical circuit of the control unit actuation should be checked with its automatic activation from the fire detector when the valve is closed. The installation site of the control unit should be well lit, inscriptions on pipelines or special stencils (unit number, protected area, type of sprinklers and their number) should be made with indelible bright paint and clearly visible. Any damage to valves, valves and non-return valves that could affect the reliability of the fire extinguishing installation must be repaired immediately. As water sprinklers for automatic fire extinguishing of transformers, sprinklers OPDR-15 are used with a working water pressure in front of the sprinklers in the range of 0.2-0.6 MPa; for automatic fire extinguishing of cable structures, sprinklers DV, DVM with a working pressure of 0.2-0.4 MPa are used. When inspecting switchgear equipment, but at least once a month, the sprinklers must be inspected and cleaned of dust and dirt. If a malfunction or corrosion is detected, measures must be taken to eliminate them. During repair work, sprinklers must be protected from plaster and paint (for example, plastic or paper caps, etc.). Traces of paint and mortar found after repair must be removed. It is forbidden to install plugs and plugs instead of faulty sprinklers. To replace faulty or damaged sprinklers, a reserve of 10-15% of the total number of installed sprinklers must be created. The inclusion of the pneumatic tank in operation should be carried out in the following sequence: fill the pneumatic tank with water to about 50% of its volume (control the level on the water gauge glass); turn on the compressor or open the valve on the compressed air line; raise the pressure in the pneumatic tank to the working pressure (controlled by the pressure gauge), then connect the pneumatic tank to the pressure pipeline, creating a working pressure in it. An external inspection of the pneumatic tank should be carried out daily, check the water level and air pressure in the pneumatic tank. When the air pressure drops by 0.05 MPa (in relation to the working one), it is pumped up. The compressor is tested at idle speed once a week. Maintenance of the pneumatic tank and compressor, carried out once a year, includes: emptying, inspection and cleaning of the pneumatic tank; removal and testing of the safety valve at the stand (in case of malfunction, replace with a new one); painting of the surface of the pneumatic tank (indicate the date of repair on the surface); detailed inspection of the compressor (replace worn parts and fittings); fulfillment of all other technical requirements stipulated by the factory passports and operating instructions for the pneumatic tank and compressor.
