【 Weak current College 】 heating and gas supply-III heating system maintenance and management

This section includes heating management content, heating systems, water conservation, operation and management of the heating system, heating system common breakdown and exclude, boilers and boiler house of the maintenance and management etc.　　A content managed, heating heating system management including heat management, network management and user management. 1. heat management
Heat management refers to the boiler and its auxiliary facilities of conservation and management, including fuel procurement and transport, slag cleaning, operation and maintenance staff training, etc. 2. heat supply network management
Heat supply network management refers to the community and building heating network for the conservation and management, including the pipeline inspection, maintenance and repair. 3. user management
User management refers to the user running the indoor thermal equipment inspection and maintenance, heating costs for the collection and use of the user's device. 　　Heating user management is heating process management of critical management areas, its main elements are: ① guide users encounter problems with the heating of property management company communication; ② education users how to save energy, reasonable heating; ③ examination room of airtightness and strengthen insulation measures; ④ user home decoration to change the location or type radiator, the required management staff on-site. Second, the heating system of water conservation in non-heating season the system stops running, to reduce pipeline and corrosion of the equipment system, all the hot water, hot water heating system for water conservation, steel radiators more emphasis on water conservation, to extend piping and equipment life. 　　Water conservation is: ① heating season ends, the system stops running, the first conduct a comprehensive inspection and repair, damaged parts or to replace the radiator; ② the system up with water and pressure testing requirements for system testing; ③ the system of water heated to 95 ℃, maintain 1.5h, then stopped; ④ with expansion tank system in non-heating period to keep the water tank with water, lack of water is water.　　III. operational management of the heating system and heating system of water conservation, in heating season ago, system maintenance and water emptying and check all equipment including boilers, piping, valves, meters and radiator, ensure that all equipment functioning, and clean the inside of the pipe and heat sink and the appearance of dust, dirt and then filled with water after processing, in line with the requirements of the water system water quality, and finally to start the heating system. In the heating system is running, the heat of the operator shall, in accordance with changes in the outdoor air temperature heat adjustment, organic changes in flow rate, temperature, pressure and other heating parameters with heating is more rational, economical and practical. In addition, you should always check the following items. ① easy to freeze the heating pipe, insulation and equipment, etc. ② motor, pump is functioning. ③ various instruments (pressure gauge, thermometer, flowmeter) is normal. ④ system all the trap, exhaust equipment, various regulatory and safety devices, etc are good and reliable. 　　⑤ indoor heating temperature and the temperature of the cooling equipment conforms to the requirements.　　For a system of pipes, valves and accessories to periodic maintenance, all systems of decontamination, filters and water at the bottom, and so should periodically clean the filth. 4. heating system common breakdown and solution heating system common breakdown failures cause exclusion () method of heating system and the end radiator does not heat the loop pressure loss ① imbalances or horizontal hydraulic offset ② system with air ① beginning from the system start, order smaller each loop risers or branch pipe on valve ② exclude system air continued heating system common breakdown causes exclusion (handle) for local heat sink is not heat pipe surface had obvious ① difference, pipe blocked ② as a pipe without obvious difference, perhaps radiator air too much or have their import branch pipes should be knocking ① gas slug rapping, if still does not address the need to disassemble the address ② open exhaust air upper radiator does not exclude hot ① may be upper radiator accumulate air ② may be upper radiator water shortage for exhaust processed ① ② to supplementing water layer heat sink overheat, lower the heat sink is not hot upper radiator flow too much, and lower the heat sink flow too little down upper radiator pipes, valves, boilers and boiler house of the maintenance and management 1. boilers and boiler house management requirements ① to boiler room all rules and regulations, including the security operation system, water treatment systems and the swap class system, but also must prepare the operation of the boiler room. ② the strict implementation of the security operation procedures and roving censorship, seriously well run record. ③ According to system design and operational requirements, to make the appropriate adjustment of equipment, boiler and auxiliary equipment maintenance to be carried out regularly, discovery failure to timely maintenance. ④ hold jobs any time shall not be unattended or secretly away. 　　⑤ class at least once flushing water and sewage, and water treatment and water quality analysis. 2. safe operation of the boiler (1) prevent boiler pressure
In the boiler operation process to maintain boiler load stability, prevent sudden decrease load, causing pressure rise; preventing boiler safety valve failure every 1 to 2 days once artificial exhaust, and periodically make automatic exhaust test, if slow, must promptly repair; periodic inspection and, if found to be inaccurate or action is not working properly, you must timely replacement. (2) to prevent overheating
Prevent boiler operating in the water, rinse water table per class, check the water level is correct; periodically clean the faucet and connecting pipe to prevent blockage; periodic maintenance, check the water level alarm and over-temperature alarm equipment, maintain sensitive and reliable; closely monitoring a level, in the event of a serious shortage of water, is absolutely forbidden to boiler water; the correct use of water treatment equipment, maintain boiler water quality standards-compliant; serious surface drainage and sewage operations on a regular basis, periodically clean the scale. (3) to prevent corrosion
According to the boiler water, effective wastewater treatment and oxygen measures to guarantee the water supply and water quality standards; strengthen the boiler maintenance work, timely and clear the soot, brushing antirust paint, maintain furnace drying. (4) to prevent cracking and Groove
　Maintain combustion stability and avoid sudden heat quenching boilers, strengthen head, pull and stress concentration of check, once found cracks and Groove, must be processed in a timely manner. (5) to prevent water hammer
Do not make sudden sharp drop in water level, avoiding the boiler water, lack of water and gas-water free, etc.
