壁挂炉常见解答 采暖炉的维护保养 1. Heating water pressure rise. This is a normal phenomenon, the thermal expansion of water in closed pipeline, pressure will be increased, the water capacity of the pipeline (the room is larger) expansion pressure is, the higher the temperature is, the greater the pressure of expansion, but in the cooling to room temperature, pressure should be restored to 1.2-1.5bar. 2, the cooling pressure is lower than the original water filling pressure. This is a normal phenomenon, the boiler has an automatic running wind (exhaust valve), running in the heating pipeline, and the radiator in the air, will be water to the exhaust valve at the furnace, the air is discharged automatically, so the cooling pressure than the original water pressure is reduced. After many times discharge and water supply, the air in the pipeline can be exhausted. Note that is not running, if the pressure is reduced, then there is leakage, need to be examined. 3, worry about the frequent start of wall hanging furnace, affect the life. Don't worry, whether imported or domestic in the program with a 3 minute delay and cooling delay function, that is to say, to reach the set temperature, must satisfy two conditions, the boiler can restart: the time has been shut down for more than 3 minutes; the lower water temperature above 5 degrees, and two conditions must meet in order to restart. 4 、 after installing the thermostat, what's the button or the button on the wall hanging stove?. The thermostat controls the room temperature, and how much water is used to heat the room temperature or the button on the wall hanging stove. For example, the temperature button on the wall hanging furnace is placed at 9, and the temperature controller is adjusted at 20 degrees centigrade, then the wall hanging furnace will be heated by 85 degrees of hot water, so as to make the room temperature reach as high as 20 degrees Celsius as soon as possible. If the temperature button on the wall hanging furnace is placed at 0 and the room temperature is set at 20 degrees, the wall hanging furnace will be heated by water at 30 degrees centigrade. Obviously, the former indoor heating speed is faster, the latter indoor heating speed is slow. So, you can put a thermostat on the stove The button becomes a temperature control knob. 5, about antifreeze. The original stove shows small umbrella, which is summer model, that is, only for sanitary hot water. Snowman shows winter mode, heating and sanitary hot water two functions are available. Anti freezing is set to show small umbrella, that is only the mode of hot water, when the wall hanging furnace does not run, when the water temperature is lower than 4 degrees, the wall boiler automatically starts to burn water to 42 degrees, so repeatedly (must be connected to ventilation, electricity). If you set the model as "snowman", it's running at low temperature, not antifreeze. Made more detailed: antifreeze function button the hot files, as long as the electricity ventilation, start the pump when the water temperature is below 9 DEG C, and strengthen water circulation, if the water temperature continues to decrease to 5 DEG C, automatic ignition stop heating to 30 DEG C, the other two buttons placed at random. You may as well try to open the balcony window. And in the shutdown state, as long as the power, ventilation, at 5 degrees, will also be forced to start to protect the wall hanging furnace. 6, about wall hanging furnace heating costs. A short period of time does not mean whether it costs or not. It's only the average value of the entire heating season that makes sense. Wall heating must pass the following procedures: first, baking room; second, wall and space endothermic heating; third, the heat balance state, that is, the room lost heat and wall furnace supply heat equal. Procedure is the most costly process. Third, it is the most gas saving process. After entering the normal heating process, it is the state of the third. Therefore, the most solar term is not to turn off the furnace, but to adjust the temperature to the minimum when the heating is not needed, and then to increase the temperature when heating, and to reduce the repetition of procedures and repetitions. Take 100 square meters as an example, a heating Ji Pingjun (including bath, cooking) daily gas consumption 6-8 cubic meters. 7, how to know the insulation condition of the room. For example, the room temperature is 18 degrees, and a thermometer is fixed indoors. After 12 hours (Bai Tian), the thermometer is lowered by 1-2 degrees, and the temperature is reduced by 4-5 degrees at night There is an air leak, which needs careful inspection. 8, how to solve the cold water before bath. First, calculate the amount of waste water, 8-15 seconds before bathing, there is no heated cold water outflow, that is, 0.16 liters / sec x 15=2.4 liters, 10 times a day for 24 liters, a year wasted water for 8760 liters, 9 cubic meters, 30 yuan. Saving method: 1. Use basin to do other things. The minimum start-up flow rate of sanitary hot water for hanging wall furnace is 2.5 liters / min. when using sanitary hot water, first open small flow, then open immediately after hot water. 2.5 liters / minute flow of simple judgment is boiled water head to form the thick water column of brush rod can. The most advanced method: using the old electric water heater and wall hanging furnace, forming a hot water center with a water tank, this method is most suitable for the toilet far from the apartment. The sanitary water is heated by the wall hanging furnace, and the water inlet of the electric water heater is connected. The electric water heater only bears the heat preservation function. For example, wall hanging furnace burning 80 liters of hot water gas consumption 0.36 cubic meters, the cost of 0.68 yuan. Electric water heater 80 liters, insulation 24 small power consumption of 1.5 degrees, and gas costs the same, continuous use, less waste, more comfortable. 9, wall hanging furnace smoke exhaust safety. The smoke pipe of the wall hanging furnace is a concentric double tube, the inner pipe is smoke exhaust, the outer pipe is an air inlet, and is communicated with the sealing chamber, and is completely isolated from the indoor. All brands of wall mounted boilers are forced exhaust (fans) balance (wind pressure switch), so smoke exhaust and air intake are outdoors, will not consume indoor air, security is guaranteed. In recent years All the explosion accidents were caused by the leakage of the natural gas hose, but there was no report of the explosion of the furnace. 10, wall hanging stove sanitary hot water change small reason. The filter blocked water tap filter blocked or cold water inlet. Remove the bellows from the cold water inlet. It can be recovered after cleaning. 11. The heating of the wall hung stove is noisy and slow. May be wall mounted boiler heating into the backwater port filter blocked, open the corrugated pipe can be cleaned, or heating pipes blocked. 12, how to drain water when cleaning filter net. The furnace heating water lines. Turn off the cold water inlet valve, open the water filling valve, turn on the faucet of the sanitary hot water, and the heating water in the furnace can be discharged. Reverse operation can re fill water operation. Turn it off. Radiator drainage, can only use the radiator of the wind. 13, changing the height of the wall over the wall of the radiator, there is often water flow in operation. As long as several times in the radiator running air deflated, and then wall furnace filled with water, repeated several times. 14, the reasons for the room temperature does not go as follows: 1, the radiator heat dissipation is not enough, this fault is easy to occur in the replacement of radiator users home. The radiator is changed to small, so that the radiator emits insufficient heat to make up the room heat Loss. 2, wet room is wet, because the wall is wet, the moisture content needs gasification and absorb a lot of heat, so the room temperature does not go, the baking room takes about a week. 3, open and stop, room temperature did not reach the balance, that is, shutdown, and the early heat release due to heat transfer between households by the outside world, so it can not reach the required temperature. 4, not heating up and down, heat loss. 15, the new house for the first time use wall hanging furnace, the more appropriate method is: 1, after the boot, the radiator temperature button is set in the zero file, with the lowest water temperature heating, and do not shut down, slow baking room does not cause wall surface, furniture cracking. 2, not to a higher temperature, is not conducive to the wall moisture evaporation, heat two is due to the heat transfer between the household and the cold gas fee to help a neighbor, not to please, whether three is open to high temperature It doesn't help, just shorten the time of the barn, and the room stays warm or not. With the lowest temperature, about one week after use, you can warm up at will. Low temperature burns about 3-4M3 every day Gas plus bath, cooking 5M3 enough. (due to the more heat needed by the gasification, the curing barn is more expensive). 3, the above four reasons are each residential new residence must face the problem, one need not worry, two do not have to impatient, the situation will be better, the temperature will rise steadily. 16, original wall hanging furnace fault display 28 reasons and repair: The meaning of 28 is: when the wall hanging furnace is heating, the sanitary hot water has flowing phenomenon. Why set this function: when heating, the water temperature is high, in the heat exchanger tube heating and sanitary hot water pipe is arranged in parallel, so the hot water temperature is higher, if the hot water outflow will exceed 60 degrees, to prevent burns, heating, does not allow less than 2.5 liters / minute sanitary hot water outflow. But more than 2.5 L / min, can be converted into hot water by heating. Failure point: (1) water faucet, sanitary hot water pipe and other water point line, there is leakage phenomenon. There are impurities in sanitary hot water flow switch, which affect the normal flow signal indication. Health hot water thermistor has fault. Fault judgment method: after closing the tap water valve, the normal heating. If 28 does not appear, proved to be from the wall to the tap water pipe, there is leakage phenomenon, please check Looking for. If the tap water valve is turned off, the heating is normal. At this time 28 or appear, but for the second, the fault, flushing flow switch or replace thermistor can (need maintenance personnel). When the water (TAP) from the boiler hot water outlet of more than 1 meters, this function can be omitted without. Users and maintenance personnel should pay attention to. Most of the failures are caused by the leakage of water from the hot water outlet of the wall hanging furnace to the faucet (including tap), and the water leakage is not enough to start the wall hanging Furnace (2.5 liters / min), not heating leakage, independent of the hydraulic meter. Objective: in order to ensure the normal operation of the heating furnace, heating furnace after running for a period of time, maintenance should be carried out. The maintenance cycle depends on the working environment of the heating furnace, the use of temperament, etc., usually designated once a year maintenance and cleaning. Time: usually for the heating season or heating season before the start of cleaning. The exact time is April 15th - September 15th. Maintenance includes the following 5 aspects: First, cleaning parts: Clean thermocouple terminal; Brush the heat exchanger to ensure the fin spacing and check the condition of the heat exchanger; Remove fan, clean up coke and dirt; Demolition of the Venturi tube and cleaning; Check the washer at the outlet of fan and replace it if necessary; Check the cleanliness of the inlet pressure pipe of the micro pressure relay and wash it if necessary; Clean the carbon and dust of the coaxial flue, and pay attention to the sealing of the inner and outer flue when installing; Note: in the process of cleaning, if you need to dismantle a part, reinstall the sealing ring should be replaced. Two, check the main function of the heating furnace: through the heating furnace temperature regulator or indoor thermostat to make the heating furnace in the heating state. Check the function of the pump; Check the ignition of burners; Check the operating condition of heating temperature regulator (stop, small amount, atmospheric quantity) Three, check the function of sanitary water, check the sanitary water for the first time, and the heating furnace is in summer function position. Check the ignition condition of burner; The second inspection of sanitary water, heating furnace in winter functional position. Check the ignition condition of burner; To check the sanitary water regulating function of heating furnace; to run the function of sanitary water under the condition of low air inflow; to detect the change of gas volume and the change of water temperature. Four. Inspection of fire safety devices Blowing out open flame, heating furnace should be cut within 45 seconds. Temperature limit protection is 87 degrees centigrade The heating temperature of the heating furnace rises to 87 degrees, and the main burner will be extinguished automatically. When the temperature drops about 10 degrees, the heating furnace will work automatically. power failure The heating furnace is in the state of work, and the heating furnace works automatically after the electric heating. Overheat protection test The heating furnace should stop working when the overheating plug is pulled out and a plug is connected. Heating temperature limiting protection Pull out a temperature limiting protection line, and the main burner should be extinguished immediately. Anti clogging detection Please stop the flue and the main burner should be extinguished immediately. Five. Other detection of the water pressure in the heating cycle The water pressure in the heating cycle should be about 1.5bar, and the water pressure should be higher than 1bar under any circumstances. Sanitary hot water temperature If the sanitary hot water flow is not enough, Check the strainer in the cold water inlet pipe. Heating temperature rise If the temperature rises too fast, check the adjustment of the bypass valve or the filter net at the heating return water. Expansion tank When the heating function is running, if the water pressure rises too fast in the heating circulating water, check the pressure of the expansion tank. In this case, the heating water and the return valve of the connecting plate are closed, and the water in the heating furnace is evacuated through the heating drain valve, and the pressure of the expansion tank is between 0.5-0.6bar.
