Huaihua City gas china electric heating vacuum hot water boiler vertical type vacuum pick our vacuum boiler selection process, you will encounter many questions. Here, the authors elaborate on with the public. Vacuum boiler cost is the cost of the host vacuum boiler, burner costs and accessories (water supply pump, control panel, valves) the cost thereof. The root causes affecting the boiler cost vacuum, bear with: Gap brand, manufacturer, production capacity skills, inspection, planning, selection and other steel products. Inside, a very important root causes such as the following: a, gas steam boiler manufacturers of the strength of the manufacturers of the strength is likely to affect, the quality of the product. Because, for a powerful companies, not only to capture the market weight more weight, occupy the right amount of experience. Moreover, Moreover, the level of professional design products. Planning levels will directly impact on the quality of the product is enormous. Affected, with the fluency of the following products, energy-saving, reliable nature, extent, and convenience. Second, the choice of good or bad metric steel, steel is the cornerstone of production capacity. Professional formal standard steel, sealed vacuum boiler is to ensure a smooth and effective. Many second-tier brands with the use of substandard or not up to standard steel, there will be a vacuum boiler products, poor fluency, large operating costs, while there reliable fault for the user to say, even when the purchase cost less, but Suizhudanque. Third, when the degree of production automation equipment vacuum boiler production capacity in the manufacturing, cutting, coil, fuse, very important skill. These three skills, both compared to the former workers through manipulation, automated production equipment, the advantage is very obvious. Due to automated manufacturing, it would be more accurate, less deviation. This also big brand vacuum boiler products, superior brand of small important thing because. Due to its production capacity in return, more then fit the planning level, to achieve the best use of formal standards. d, the step of detecting some domestic manufacturers, there is no vacuum boiler through rigorous product, manufactured assessment evaluation. Stress test ended, as professional products. Here is the working methods irresponsible. Professional checking step comprising at least: Stress test test test inert gas, welding gap inspection, inspection of the seals, and factory test run. Indispensable, even-handed. Only so, only to grasp the professional user to ensure delivery of products, allows users to use the time following, reduce non-compliant products have caused, directly affect the user's normal production activities. 5, a large part of the sale of second-tier brands, good or bad, there is no after-sales. Full service entrusted to the agents responsible. But a majority of the dealer, not a professional team of professionals. After the cause does not meet the standards will result in non-stop prevaricating, or simply can not be achieved with the consequences. The above is a vacuum boiler costs, direct influence of roots. Normally, good, excellent vacuum boiler product costs, plus a host vacuum boiler burner, in almost every 700KW, pick up million and about.

Large bath, bath with hot water china electric heating vacuum hot water boiler as what are the problems, baths and bath are all civilian areas, mainly by providing heating and hot water to the majority of people take a bath for heating, under normal circumstances, there are three main ways of heating their Zhang situations: 1, the traditional coal-fired steam boilers coupled with heat exchangers this method has also been widely used before the second five, but as residents increasingly high demand for this piece environment has gradually withdraw from the stage of history coal-fired boiler currently in the State Department regulations already belong to one of the forced removal and renovation projects, so this method is not suitable for urban populations. 2, the use of biomass pressure hot water boiler utilizing biomass energy field is currently the best known way, the low cost of the boiler, the fuel in the fuel cost is lowest of all, but because of the limitations of raw materials must be equipped with fuel special fireman job, and because biomass fuels, after all, just a lot of places can not be fully developed so popular is the future direction of development. 3, gas-fired hot water boiler vacuum vacuum hot water boiler is the new trend in hotels heating sector. Vacuum hot water boiler's heat exchanger is built, it can be directly required hot water temperature. So vacuum boiler for heating and sanitary hot water are no secondary heat exchanger. If for sanitary hot water, then only need to install a hot water tank, and then directly set the heating water temperature can be directly used for water heating. Vacuum hot water boiler for heating and advantages of the hotel Hotel sanitary hot water supply are: ① security: Vacuum negative pressure boiler operation, there is no risk of explosion, very safe, is expressly provided free national supervisory inspection of boilers. ② system is simple: direct water, and heat exchangers can be built multiple, simultaneous heating and sanitary hot water supply. Efficient ③: a high thermal efficiency, thermal efficiency is generally over 94%.

Maintenance and corrosion protection of a hot water china electric heating vacuum hot water boiler, water supply oxygen due to some timely accumulation of dissolved oxygen corrosion of hot water boiler will result in increased water supply process, therefore, at the same time equipped with the appropriate oxygen equipment should be better the efforts to control the entire water supply. The oxygen present embodiment mainly sodium sulfite chemical reaction oxygen, this effective method of oxygen can fully reduce the overall corrosion to metal. Meanwhile, some capacity is relatively increased water boiler, may also be employed in high vacuum or low oxygen equipment, a reasonable way is to use hot water boiler air evacuated, forming a gas hot water boiler pressure less than atmospheric pressure will reduce air leakage phenomenon occurs, play a good maintenance effect. Second, strict control of the pH of the boiler water in accordance with the regulations of the country, the pH of the boiler water is controlled within a predetermined range, this can be well protected by film formation, avoiding corrosion of the metal walls of the hot water boiler . Case of pH value rises or falls appear outside the furnace, to take timely measures to maintain, when the entire index is below 10, you can put some alkaline agents on the hot boiler to an appropriate increase to a normal pH, can also be run by using trisodium phosphate and sodium hydroxide to adjust the dose to accurately control the pH of the water throughout the furnace, so that, to maintain good control effect, helps to reduce boiler corrosion, build clean and efficient mode. Third, strengthen the maintenance of boilers disabled during shutdown, such protective measures are not taken, the boiler water and steam system of the metal surface corrosion is dissolved oxygen, since the boiler generated during operation is an alkylene iron corrosion products compounds, can become disabled at the time of high iron oxide compound, which makes corrosion process is repeated down the line. And therefore must take appropriate protective measures during boiler shutdown is disabled, avoid and mitigate corrosion of the boiler. Maintenance of two ways: First, dry maintenance, and second, wet maintenance Wet maintenance Currently we have taken as follows: (1) the pot of water after shutdown exhausted, remove scale, impurities and soot. (2) off (or blocked with the blind plate) each of the ducts of valves connected to the boiler. (3) The demineralized water injected into the boiler to a minimum level, with special preparation of a good basic corrosion pump liquid injected into the boiler. (4) When all the injection liquid corrosion boilers, boiler water supply valve is turned on, the boiler filled with demineralised water until the pot of water drained out from the valve, closing the valve and emptying the water supply valve. (5) Open special boiler water circulation pump, so that everywhere in the boiler alkaline solution concentration uniform corrosion. (6) During the maintenance, you should always do external examination, and regularly testing pot with water, and liquid or alkalinity level drops, should identify the reasons for timely processing and additional liquid. (7) periodically open water circulation pump, the liquid concentration consistent throughout. (8) during the wet winter maintenance of the boiler, the boiler temperature must be kept above 5 ℃ and do the following. a. during the entire maintenance, raw Microflame oven regularly in order to maintain the outer surface of the heated drying. b. To start a regular water circulation pump, the concentration of the solution is consistent throughout. c. also regularly take the solution testing, if the alkalinity is reduced, should be supplemented. d. Winter freezing measures to be taken. Conclusion of people using the hot water boiler in the current society continues to increase, for the maintenance and repair of hot water boiler has been people's attention, but at a certain point of view, people are now plagued by the boiler normal use of the main factors that boiler corrosion situation occurs, this corrosion occurs not only will make the life of the boiler there is a certain decrease in the safety of the boiler will make a corresponding reduction, so this needs to boiler rusting conduct a comprehensive analysis, and in accordance with the results of the analysis put forward countermeasures boiler fundamental Rusty effective solution, so that the development of China's water boiler to get some protection.
