Comparison of school hot water vacuum boiler price failure rate and safety between boiler failure rate: 1, degree of vacuum in the vacuum boiler furnace boiler * important indicator of stable stable operation of the four main factors often influence the degree of vacuum: 1) boiler and valves, The instrument has no leak points, including the inlet valve and instrument currently can not guarantee no leakage occurs within 3 years. 2) whether the control section failure, the boiler controller and negative pressure controller also fails in operation is inevitable, such as the failure rate even higher internal controller 3) a vacuum pump, if the three-way electromagnetic valve normal, due to the vacuum pump, three-way solenoid valve is not run frequently, imported and seizure operation also prone to failure. 4) Load not have mutations, altered boiler load is normal to the boiler, the boiler can meet generally 30% -100% of the load adjustment. Above failure will cause the boiler to change the degree of vacuum, should check the airtightness of the boiler, the control section is normal, the vacuum pump, the three-way solenoid valve is normal, check load changes, if the check is normal and negative pressure controller setting, after everything is normal vacuum level recovery boiler can also normal use, or to repair a comprehensive inspection shutdown. The actual operation of the vacuum boiler breakdown maintenance rate is higher than the pressurized steam boiler, a steam boiler control requirements than. 2, pressure boilers including a boiler only basic time, temperature, level control, controller selects imported hot water boiler, as compared to a lower failure rate. No need to maintain the degree of vacuum control equipment, no complicated control equipment, personnel operating requirements simpler than vacuum boiler, the less chance down for maintenance, the actual running hot water boiler to be much more stable. Compare the safety of boiler: 1, vacuum boiler if for the above four factors the degree of vacuum boiler is not guaranteed, it may cause a rapid rise in boiler pressure, boiler is a closed structure, if careless operator, it is possible to be there dangerous pressure steam boiler, vacuum boilers run more negative safety is based on the premise degree of vacuum boiler must not be problems. 2, atmospheric pressure hot water boiler boiler-through the atmosphere, as simple as boiling water, any failure will not cause pressurized boiler, boiler more secure, truly without any danger.
Steam electric school hot water vacuum boiler price maintenance and fast boiler pump classification Henan Xiao Bian told you about the company's steam boiler maintenance and electrical vacuum pump steam boiler maintenance classification should pay attention to 1, boiler maintenance, 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. The vacuum pump is divided according to use: a roughing pump starts to decrease from atmospheric pressure to a vacuum pump system to work the other pumping systems. 2. High vacuum pump operating in a high vacuum range. 3. The main pump in the vacuum system, the vacuum pump used to obtain the desired degree of vacuum. 4. foreline pump foreline pressure is maintained for a further vacuum pump in which a pressure below the critical backing. 5. coarse / low pressure pump starts from the atmosphere and for obtaining a low degree of vacuum of the vacuum pump. 6. The booster vacuum pump is mounted between the low and high vacuum systems to improve the efficiency or reduce the vacuum foreline pump capacity requirements. 7. The ultra-high vacuum pump works in the ultra high vacuum range. 8. A pump is maintained in a vacuum system, when the gas amount is small, can not be effectively utilized master, before the pump, In this case, with a smaller capacity auxiliary backing pump to maintain the main pump containers or maintain a desired degree of vacuum . 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!
Since the use of advanced technology vacuum school hot water vacuum boiler price control, automatic failure level, low alarm, the system may notify the user and automatically cut off power, to avoid losses due to lack of water. Forming a special design of the structure, it can be a machine. Also provides multi-channel, the temperature difference between the hot water to meet the various needs of users for central air conditioning, heating, sanitary hot water, high-level swimming pools, hotels, hotels and other hot water supply. It can provide process water for all types of industrial and mining enterprises. Imported burner has good insulation effect, applicable to an altitude of 3000 meters below the area. For heating, the heat of the burner indirectly received by the negative pressure steam. Under standard conditions, the vacuum degree of the vacuum chamber with increasing vacuum chamber -76cmHg vapor pressure decreases, the heat medium when the vapor temperature reached 94 deg.] C negative, lowered vacuum degree -15cmHg, start and stop the vacuum switch burner, a heat exchanger with take the heat. Steam temperature and the heat medium decreases, the negative pressure increases to maintain a constant vacuum. Switching cycle start-up burner, so as to achieve the purpose of heating and water heating. Minimal vacuum chamber of the vacuum furnace -15CMHG, up to -76CMHG, negative pressure is always maintained in a state of absolute security, the steam temperature of the vacuum chamber and the vacuum chamber of the heat medium can be increased to 94 deg.] C, the heating and hot water water temperature up to 80 ℃. Boiler body and not subjected to any pressure of the vacuum chamber, the heat exchanger can withstand the pressure. Therefore, no need to check the entire process from commissioning to operation, the boiler does not need permission. Advantages advantages of vacuum hot water boiler vacuum boiler operation is a negative pressure, safe and reliable, no explosion, not subject to supervision and inspection, can be placed on the roof, the basement does not scale, compared to other hot water boiler long life vacuum heat the boiler water pressure and hot water boiler and Comparative residential heating system pressure hot water boiler is mainly used for heating boilers cell. It was heated in two ways: floor heating, a heating radiator. Residential district heating system depends on the height of the floor to decide whether heating alone. Vacuum hot water boiler operating principle is to use the steam generated by the boiling of water at low pressure, water and steam condensation heat transfer and heat output mode. The interior of the apparatus is a closed vacuum chamber. Combustion heat medium boiling water was evaporated in a vacuum chamber to produce a negative pressure steam, steam condensation outside the heat transfer tubes, the inner tube heating cold water supplied to the user, the steam condenses into water droplets return to the heat medium heating evaporation again, completing the cycle.
10th June this year, the provincial government agrees that the ecological environment in Zhejiang Province Office issued the "Notice on the implementation of special emission limits national emission standards of air pollutants" (hereinafter referred to as "notice"), marking the full implementation of Zhejiang Province especially national emission limits of air pollutants.
"Special emission limits" is mainly for land development density is already high, the environment carrying capacity began to weaken, or less atmospheric environmental capacity, ecological environment is fragile, more stringent prone to serious air pollution problems in sensitive areas and set the emission limits. Implementation of the national emission standards for special emission limits, Zhejiang Province in favor of further strict pollution management, reduce pollutant emissions, to further improve air quality, but also help promote the integration of the Yangtze River Delta environmental standards.
In fact, back in 2013, Zhejiang has already begun in some areas particularly the implementation of the national emission standards limit emissions of air pollutants, but was limited to Hangzhou, Ningbo, Huzhou, Jiaxing and Shaoxing, Hangzhou Bay five cities; and this is to expand to the province level. In addition to a wider geographical range, "advertisement" clearer pollutant emissions targets, e.g., volatile organic contaminants not individual indicators, including not only non-methane hydrocarbons, total volatile organic compounds such as benzene, benzene and other pollutants indicators meet the definition of volatile organic compounds should be performed; also more involved in the industry, such as boilers only provides original coal-fired boiler, and "notice" it covers all types of boilers (including oil, gas).
It is reported that, in the national emission standards have been implemented, a total of 25 standards set emission limits of air pollutants in particular; at the same time, the recent ecological Ministry of Environment and the State Administration of market regulation has released three national emission standards of air pollutants, namely, pharmaceuticals, paints, inks and adhesives and volatile organic compounds fugitive emission control standards, and will be from July 1, 2019 implementation. According to "notice" requirement, the province is also involved in the enterprise should implement special emission limits specified in the three standards, the execution time of the emission standards time synchronization. Provincial Department of Atmospheric environment Department official said: "The implementation of the national emission standards for emission limits in particular, help to further strict management of our province pollution, reduce pollutant emissions, to further improve air quality, but also help promote environmental protection in Yangtze River Delta standard integration.
