State all the more attention to environmental protection, to provide more excellent atmosphere, we respond positively to the country's environmental protection, promote the electric heating condensing vacuum hot water boiler from coal to gas project. Among the many boiler suppliers, we chose the fast boiler. First, the party quickly done very well in terms of cleaning the boiler, the second is fast side also very comprehensive after-sales involved. The optional gas boiler was used after running fully meet the needs of our pharmaceutical production, both energy-saving and environmental protection, but also a very high thermal efficiency, saved us a lot of fuel costs. --customer feedback

Related problems of electric heating condensing vacuum hot water boiler corrosion deactivated 1, deactivate the boiler corrosion damage to the concept of corrosion occurring at the boiler cold standby, hot standby, or during servicing referred to deactivate corrosion. Disable boiler corrosion, primarily because the metal surface is not completely dried during the shutdown and oxygen in the atmosphere continues to leak into the cause. Although the internal and external boiler heating surface corrosion during shutdown occur simultaneously, but internal corrosion is more serious than external corrosion, so corrosion is mainly refers to disable the internal heating surface corrosion. 2, after the cause of corrosion disable shutdown, with decreasing pressure, temperature, boiler water vapor condenses into water, there will be a vacuum inside the boiler, outside air leakage into the furnace, oxygen and moisture vapor case, it is prone to corrosion of metals. Due to the structure of the boiler, if certain measures are not adopted, disabled corrosion is inevitable. Vertical e.g. superheater is not within the water in the superheater drained. When the internal heating surface metal junction with a water-soluble salt scale, will form a high concentration salt solution when it absorbs moisture, so that increased corrosion disabled, and the formation of ulcers corrosion. In this case the inlet of the superheater is often present. Because of the separated saturated steam is always when entering the superheater with a small amount of boiler water, saturated steam into the superheater absorb heat, water is evaporated into steam oven, and the boiler water containing salt is deposited on the inlet tube wall superheater. 3, disable corrosion prevention, mitigation method (1) In order to prevent or mitigate disabled corrosion protection measures should be adopted shutdown. Many shutdown protection methods, mainly divided into two categories: wet and dry protection protection. Wet disable protection commonly used in the short time, for example within one month. Wet common method is to protect the other peroxygen filled in boiler water, or an aqueous solution of alkali, maintaining a pressure of 0.3 ~ 0.5Mpa, to prevent air from leaking into the. (2) If a longer shutdown, or cold weather, in order to prevent freezing equipment, should be protected by a dry method. The method is: After shutdown, the temperature dropped to 70 ~ 80 ℃, the furnace let go all the water, using the water in the boiler will heat the entire heating surface evaporated to dryness, and dried with compressed air furnace without blowing vapor all off-contained anhydrous calcium chloride and then placed in the drum of the container. Per cubic meter of water volume ratio 0.5 ~ 1.0L of calcium chloride was placed (e.g., with lime according to 2kg / m3 basis), then the manhole is closed, periodically checked and found to be replaced when the desiccant into powder. (3) may be filled with nitrogen or ammonia gas charge protection, their preparation and use as a desiccant. Since ammonia is lighter than air, so protection during charging and ammonia, the ammonia gas should enter the upper exhaust air from the lower portion. Nitrogen is slightly lighter than air, can enter the upper portion of nitrogen from the exhaust air from the lower portion. To prevent air from leaking into, the pressure should be maintained 0.3-0.5Mpa, the pressure reduction should replenish ammonia or nitrogen.

Steam electric electric heating condensing vacuum hot water boiler 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!
