Boiler is how the classification? Press export steam parameters of how to classify? Classification of the boiler is very extensive concept from different angles have different classification, can be classified by application area, according to the export media classification, but also by the pressure of the boiler classification. If the classification parameters according to the steam outlet, then find out which parameters steam boiler, wherein the boiler comprises evaporation, steam pressure, steam temperature etc., and is classified according to the main points of the outlet steam pressure: low pressure boiler (P <2.5MPa ), pressure in the boiler (22.5
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!
Hot water boilers are classified according to what conditions according to different hot water boiler fuel can be divided into electric water boilers, hot water boiler fuel, gas hot water boiler, coal-fired hot water boiler; can be divided according to whether atmospheric pressure and two kinds of hot water boiler pressure hot water boilers, hot water boilers we usually call refers to the atmospheric pressure hot water boiler, due to its safe operation, people bathing or heating largely adopted this pressure hot water boiler. 1, the tubular assembly Computerized water boiler controller, all the functions are stored on a smart chip, intelligent, digital boiler, automatic, user-friendly, intelligent control of boiler water, water reaches the automatic stop heating; large-screen font temperature, boiler water temperature at a glance. 2, boiler water temperature can be freely set from 10 deg.] C to 100 deg.] C, the boiler can supply both hot water bath can provide water for drinking, may be a dual oven. 3, the top of the furnace through the air opening is provided, the boiler is in an unpressurised state, there is no danger of explosion, while the machine is equipped with thermal protection (ultra-high-temperature furnace during the heating tube buzzer alarm and automatically stop working, secondary overheat protection (boiler housing temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), anti-dry water protection (when the furnace is less than the water level is very low, the boiler is stopped and an alarm beep), etc. .2 number of security, pot such hot water boiler drum cartridge type hot water boiler, early mostly modified from a steam boiler made, which in the case of boiler water within a boiler of natural circulation. in order to ensure safe and reliable boiler water cycle, the boiler requires to have a certain height, so such larger boiler, steel consumption, and the cost is relatively increased. However, since this type of boiler capacity and can maintain the natural water cycle, when the system pump is suddenly stopped, the pot can be effectively prevented vaporization of water. it is also for this reason natural circulation hot water boiler in our rapid development.

Currently seven injured in hospital emergency treatment, cause of the accident is still under investigation, rehabilitation disposal is also an orderly manner.
Heartbreak is that similar incidents happened from the last time, only 28 days.
At 15:30 on January 2019 May 2009 55 points, Zhangjiakou City Hall Ltd. Hong Mei generating boiler scalding accident, three people were killed and one injured.
Boiler special equipment is clearly defined our country, whether it is manufacturing, purchase, installation, operation or maintenance, have strict operating guidelines. Now many have adopted new boiler intelligent control, operational safety compared to conventional boilers, more convenient; but that does not mean foolproof, vigilant and master the correct method of application, in order to minimize accidents frequency. After all, the cost of each accident are living lives.
