About Code of Practice Code of Practice for the safe operation of the hot water boiler hot water boiler hot water boiler safe operation because of its specificity required safety practices. Understandable that the normal life and production are inseparable from the use of the hot water boiler. How hot water boiler safety issues need to be protected? 1, carefully check the work before the hot water boiler, drainage, gas pipe fittings, safety valve, pressure gauge, water level, is sensitive so that, after confirming it is safe to operate. 2, with both hands to manipulate when Sheung hand to open the door of water, whereupon the other hand the water injector and valve open, the water naturally into the furnace. When stopped, the steam valve should be closed first, then turn off the water door, switch and valve, the front face must escape to avoid soft drinks out of the accident. 3, hot water boiler in operation, inspection departments to pay attention to observe the pressure and water level. Fireman are not allowed to leave their posts without permission, when night work, avoid dozing off, more sleep deprivation, in order to avoid accidents. Hot water boiler blowdown, must be performed once per shift, adjust the water level in the sewage before, slightly higher 2/3, followed by sewage. 4, the water level table class must be flushed once. When flushing, according to established procedures, the first closure valve and open the drain valve, flush valve steam, steam at this time pay attention to the origin is blocked. Steam valve is then closed, when attention is blocked antecedents water. Flushing valve, until the water becomes steam, some a little longer, in order to guarantee no false water level. Hot water boiler coal must be checked, to prevent coal detonator explosives and other explosives thrown into the furnace, to prevent the risk of explosion. 5, to always check the temperature of the motor housing and the machinery, such as mechanical failure or an electric motor with a fever more than 60 degrees, stop testing immediately. Hot water boiler normal operation, the vapor pressure shall not exceed the operating pressure, the safety valve inspection once a week.
Components of the gas steam boiler There are several both production and life, we often gas steam boiler is used, and therefore the author gave us sort out what the associated structural gas steam boiler. First, the blowing apparatus: the blowing device placed inlet filter, through the use of extraction air blower burner was added to achieve an amount of change fire. Second, the water pump: main condenser is pumped from the water softener is then added to take thermal efficiency steam boiler flue gas emissions caused by water once preheated. Third, the fuel gas system: an interface comprising natural gas, burner, natural gas adjusting means. Fourth, the protection valve: placing a certain pressure value, higher than the preset value independent relief. Fifth, gas steam boiler electric control system and other in front of these two would certainly be an integral component of a gas steam boiler, assumptions made when the boiler water quality standard deviation, is not to turn the boiler, should pay close attention. At the time of manufacture, and should always check the gas steam boiler maintenance, maintenance inspection time for serious recording, only careful and thorough use, unswerving overhaul inspection, to be able to increase production efficiency to a greater extent, not only negative results can occur .
Steam boilers common faults and submersible pumps fast boiler's Henan Xiao Bian introduce a common steam boiler failure problems common faults and submersible pumps steam boiler water level is with you, the causes and solutions to a steam boiler water level is a common problem its reasons: 1, the water level is too low installation; 2, water, a water pipe connected too small; 3 have a water level or a low level display instrument automatically when the water level on only one boiler; 4, drainage water gauge no grounding drain cock; 5, the drum water level is an effective, other water damage; 6, the tap water is screw fixed; 7, the tap water gauge leak, leaking; 8, water gauge false water level on a display; 9, the drum water level in the two water gauge level of inconsistency; water glass is often broken; 11, water glass is no guard; 12, the water level is low level indicating no glass panel represents red; 13, level glass plate is dirty, the water level observation is unclear. The main reason is because of 1-4 above design, installation or alteration of dislocation caused. When the steam boiler with a low water level status is when the drum water level is only one case, because the internal balancer lowland water's leakage short circuit (can not be detected at that time), causing lowland water level is high water level appears ( the so-called full of water), while the water level on the drum have shown that low water levels (and may even see the water level), then the fireman because they can not determine the true level of the boiler will go immediately and check the water level on the drum, it will be very serious water shortage delays container boiler accident occurred. Some even show the water level too low trust level's status, and take a lot of sewage, mistakenly steam boiler water when filled with water incident handling, acceleration accidents, there is precedent for such incidents to be investigated. Then, the above-mentioned reasons for the failure of 5-9 main problem is the boiler running for long periods of time rinse water, a daily maintenance is not carried out, resulting in water cock rust, gas, water and even the block, or insufficient packing or aging deterioration . False water level phenomenon, in addition to gas, water or even the cock pipe is blocked, but also could be vapor, the water pipe connected to the water level due to misalignment connected; steam, water tap handle installed the wrong position resulting cock closed, since there poor water quality, the water level in the boiler and false priming. Water gauge glass is broken mainly steam, water faucet centerline not aligned, the presence of glass bending stress; long glass without expansion gap; water gauge is being cold draft at window glass, and glass pipe quality was poor. Submersible pump is a mechanical and electrical integration of high-tech products. In recent years, due to the submersible pump in a sealed, insulation, cooling and monitoring technologies have made great progress, but also successfully achieved the automatic coupling pumps and water pipes, so that the large diameter submersible pump application significantly faster. Since diving save electric pumping station project investment, quick installation and maintenance, operating conditions greatly improved equipment reliability and service life improved significantly. At present, China is not only the production and installation of large-diameter 900 mm below the axial and mixed-flow pump, can produce diameter 1.4 m and 1.6 m large submersible pumps, has laid a good foundation for the promotion of technical diving electric pump station. Gao dive afraid of flooding, but also has good maneuverability advantages of quick removal and installation, able to cope with the water level soared, chestnut room flooding and other emergencies pieces, large-scale changes asked of submersible pumps. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!
In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process.
