electric water boiler thermostat
Henan newly installed gas boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.
Due to increase market demand for air conditioning, we increased the number of production lines, faced with the urgent need of a steam boiler problems. Emergence of fast boiler is time for us to solve this problem. From the start of contract manufacturing to transportation to our company for installation and operation, Fang fast only 35 days to solve our urgent needs. --customer feedback
1 electric steam boiler maintenance, maintenance when the boiler must be cut off and must relief. 2, the burner every two months to be removed from the boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. 5, the boiler stops longer running time, cut off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, slow fire the pot with a burner after drying (burn time not too long, to avoid damage to the boiler), then drain all of the gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve.
Security issues should be noted that the use of hot water boiler Xiao Bian below to explain the precautions electric boiler Henan fast boiler hot water boiler for you, especially in a hot water boiler should note that there are a lot of security risks in the application process, the application process in security Council should pay attention to some key points. Gas hot water boiler with environmental protection, energy saving, safety, distinctive features automatic operation, it is very convenient application, and the other, since the operation of the tertiary industry, the New Deal judiciary incentive, gas hot water boiler increasingly suffer Everybody close friends. Gas steam boiler combustion method underlying the choice of machine, two round configuration, sufficient to ignite fuel, and the smooth operation of the boiler occupies less space, with the spoiler inserted smoke tube, ease exhaust rate, change to enhance calorie, high calorific value furnace, reduce the cost of customer application processing computer parts hot water boiler type boiling furnace control panel, all of the action is stored on a smart chip, to maintain the automation, intelligence, intelligent, personalized furnace, furnace temperature Zidongkongzhi, exceeds the temperature was warmed automatic termination; display font sizes that vary depending on temperature, boiler water temperature straightforward. In the operation of the hot water boiler, be sure to comply with the dress shirt, carefully every part of the furnace system, such as the barometer, valves for respiratory notes, such as water level, then work can be done again. When irrigation, while irrigation water to the requirements, be sure to pay attention do not have one-handed operation, one hand open irrigation machine valve, turn off the water valve before the first turn off the water valve. Such order is not inverted, turned off when the steam valve, not towards the river surface. Avoid splashing hurt face. When the furnace had work to do, be sure to many people at all times to guard the water and barometer, never allow dereliction of duty. When do you work late, you make sure good rest at noon, as you doze off at night is not easy. Because if what was forgetful, they would generate security events. Furnace must exclude every night, every night the water level gauge must be removed. Motors and other industrial equipment should be regular maintenance, if it is found everything is not normal, you should check. Each week, check the safety factor of the valve.
