Desenvolvimento do duto de ar TDF<\/strong><\/li>\n<\/ul>\n\n\n\nDeveloped countries such as the United States and Europe have adopted common-plate flange air ducts since the late 1980s. Now, this process has been widely used in various ventilation and air-conditioning projects. China only began to introduce this process technology at the end of the nineties. At that time, due to the lack of supporting equipment for the processing of common-plate flange ducts, and the lack of approval by national regulations, it was not promoted and applied. With the continuous revision of national regulations and the recognition of the common-plate flange connection method, the domestic application of common-plate flange ducts is becoming more and more popular. <\/p>\n\n\n\n
Especially since entering the 1990s, the country has developed faster and faster, and various commercial buildings, subways, stadiums, exhibition venues, theme parks, etc. have sprung up. Therefore, the amount of air ducts used as an important part of air conditioning and ventilation systems is increasing every year, and the requirements for them are also getting higher and higher. TDF flange air duct<\/p>\n\n\n\n
Chinese scientific and technical personnel and engineers from air duct processing plants have successively developed domestically-made common plate flange duct processing equipment through the introduction and absorption of common plate flange processing machinery. From the initial single piece of equipment to the now popular three-line, Four-wire equipment, and then to more advanced five-wire and six-wire equipment. Due to the popularization of processing equipment, the widespread application of common-plate flange ducts has been accelerated. TDF flange air duct<\/p>\n\n\n\n
At present, the production line of common-plate flange duct has become necessary equipment for large-scale construction and installation enterprises. At the same time, the ability to produce common-plate flange ducts has become an important factor affecting the undertaking of key HVAC projects. So its development prospects are getting better and better.

There is no need for heat preservation on site. When the air conditioning system is running It achieves the same thermal insulation effect as the external insulation of the air duct.

When laying insulation cotton, the inner surface of the air duct should be clean and flat, free of oil and dust. The inner surface of the glue should be evenly painted, and the brushing rate should be greater than or equal to 90%. TDF flange air duct<\/li>\n\n\n\n The glue used for pasting thermal insulation cotton must meet environmental protection requirements, and no toxic or harmful glue should be used. TDF flange air duct<\/li>\n\n\n\n The thermal insulation cotton must be clean, free of pollution and dust, and must not use deformed and squeezed thermal insulation cotton. Insulation cotton should be made of non-combustible materials, environmentally friendly, and non-toxic. TDF flange air duct<\/li>\n\n\n\n The thermal insulation cotton should be unpacked as soon as it is used to ensure that the thermal insulation cotton is flat and free of wrinkles, moisture, and dust on the surface. TDF flange air duct<\/li>\n\n\n\n When the thermal insulation cotton is glued to pave the thermal insulation nails, the machine will automatically nail the nails (the nail spacing can be adjusted), and it must be carried out in strict accordance with the size requirements of the specification, and no missing or under-driving is allowed. TDF flange air duct<\/li>\n\n\n\n When laying the thermal insulation cotton, there should be no joints in the horizontal direction, to avoid blowing the thermal insulation cotton joints apart when the air duct is running, which may cause hidden quality hazards. TDF flange air duct<\/li>\n\n\n\n Quando o tubo de ar \u00e9 atingido com pregos de isolamento, a densidade deve ser distribu\u00edda uniformemente, n\u00e3o menos que 16 por metro quadrado, e o mesmo se aplica a cotovelos, t\u00eas e tubos redutores.<\/li>\n\n\n\n When processing pipe fittings (tees, elbows, reducing diameters), you must pay attention to the leaks at the corners. Should be the mainly mechanical seal, supplemented by sealant treatment. After each pipe is processed and formed, quality inspection is required (light leakage inspection if necessary, and insulation cotton will be laid after it is qualified).

Colocar materiais de isolamento na f\u00e1brica, a qualidade \u00e9 f\u00e1cil de controlar; os pregos de isolamento s\u00e3o soldados, o que \u00e9 firme e confi\u00e1vel; economize o tempo de instala\u00e7\u00e3o e encurte o per\u00edodo de constru\u00e7\u00e3o do duto de ar no local; o mais importante \u00e9 que, ap\u00f3s a instala\u00e7\u00e3o do duto de ar, o formato \u00e9 bom, bonito e organizado, e a apar\u00eancia geral \u00e9 boa.<\/p>\n\n\n\n
\nVantagens da instala\u00e7\u00e3o no local<\/strong><\/li>\n<\/ul>\n\n\n\nComo n\u00e3o requer isolamento externo, \u00e9 especialmente adequado para instala\u00e7\u00e3o em espa\u00e7os pequenos e instala\u00e7\u00f5es de uma etapa. \u00c9 especialmente adequado para o sistema de ventila\u00e7\u00e3o e ar condicionado de grandes parques tem\u00e1ticos. Porque a maior caracter\u00edstica dos parques tem\u00e1ticos \u00e9 a altura de instala\u00e7\u00e3o elevada de muitos parques infantis, revis\u00e3o das condi\u00e7\u00f5es mais baixas e muitas fun\u00e7\u00f5es O espa\u00e7o da sala \u00e9 pequeno. Uma vez que a tubula\u00e7\u00e3o integrada \u00e9 instalada (especialmente a instala\u00e7\u00e3o do duto de ar), \u00e9 dif\u00edcil ter espa\u00e7o suficiente para trabalhar. A instala\u00e7\u00e3o s\u00f3 pode ser instalada em uma etapa. Como n\u00e3o precisa ser isolado externamente, ele economiza espa\u00e7o de instala\u00e7\u00e3o, economiza tempo de instala\u00e7\u00e3o, encurta o per\u00edodo de constru\u00e7\u00e3o e reduz os custos de engenharia.<\/p>\n\n\n\n

Al\u00e9m disso, devido ao uso de linhas de produ\u00e7\u00e3o autom\u00e1ticas, a precis\u00e3o e a qualidade da produ\u00e7\u00e3o s\u00e3o mais f\u00e1ceis de controlar. Tamb\u00e9m reduz a quantidade de engenharia anticorrosiva da cantoneira de a\u00e7o, o que reduz a polui\u00e7\u00e3o da pintura para o meio ambiente, e reduz a polui\u00e7\u00e3o sonora causada pela montagem e batimento da cantoneira flange.<\/p>\n\n\n\n<\/figcaption><\/figure>\n\n\n\n\u00c2mbito de aplica\u00e7\u00e3o<\/h2>\n\n\n\n O duto de ar flange TDF com isolamento interno \u00e9 adequado apenas para a produ\u00e7\u00e3o e instala\u00e7\u00e3o de dutos de ar de sistemas de ar condicionado de baixa e m\u00e9dia press\u00e3o, exceto para sistemas de ar condicionado de purifica\u00e7\u00e3o e preven\u00e7\u00e3o e exaust\u00e3o de fuma\u00e7a. <\/p>\n\n\n\n
Com a crescente mecaniza\u00e7\u00e3o da constru\u00e7\u00e3o de engenharia, o duto de ar com flange TDF \u00e9 adequado para a produ\u00e7\u00e3o de linhas de produ\u00e7\u00e3o totalmente autom\u00e1ticas. Para acelerar o andamento da constru\u00e7\u00e3o e melhorar a qualidade do projeto, o duto de ar de flange TDF \u00e9 cada vez mais utilizado. Ent\u00e3o, quais s\u00e3o o processo tecnol\u00f3gico e as precau\u00e7\u00f5es de instala\u00e7\u00e3o do duto de flange TDF? Vamos olhar juntos.<\/p>\n\n\n\n
\nProcesso Tecnol\u00f3gico<\/strong><\/li>\n<\/ul>\n\n\n\nA produ\u00e7\u00e3o de se\u00e7\u00f5es retas de tubo de duto de ar geralmente adota o seguinte processo: sele\u00e7\u00e3o e reinspe\u00e7\u00e3o da chapa de a\u00e7o galvanizado \u2192 Refor\u00e7o da prensa na linha de produ\u00e7\u00e3o (comprimento lateral maior que 630 mm) \u2192 loft de computador \u2192 Corte de canto e cisalhamento \u2192 Dobramento de borda \u2192 Conforma\u00e7\u00e3o de flange TDF feita \u00e0 m\u00e1quina \u2192 Dobra \u2192 Produtos semiacabados transportados para o canteiro de obras \u2192 Forma\u00e7\u00e3o de bretamento \u2192 Instala\u00e7\u00e3o de conectores de flange de conex\u00e3o (conforma\u00e7\u00e3o de duto reto) \u2192 Confec\u00e7\u00e3o de selante e gaxetas \u2192 Conjunto de duto de ar \u2192 Instala\u00e7\u00e3o de grampos de mola \u2192 Enforma\u00e7\u00e3o de refor\u00e7o \u2192 Inspe\u00e7\u00e3o de qualidade.<\/p>\n\n\n\n
Se estiver perto da f\u00e1brica de processamento ou se o custo de transporte for pequeno, a mordida do tubo de ar e o flange de conex\u00e3o podem ser instalados diretamente na f\u00e1brica. Geralmente, considerando o problema de custo de computa\u00e7\u00e3o, produtos semiacabados s\u00e3o usados para processamento, e a mordida e a instala\u00e7\u00e3o do flange de conex\u00e3o s\u00e3o conclu\u00eddas no local. Tubos de formato especial geralmente usam lofting e mordedura no local. O processo de instala\u00e7\u00e3o do tubo de ar n\u00e3o \u00e9 muito diferente daquele do tubo de ar com flange de a\u00e7o angular, portanto, n\u00e3o o repetirei. <\/p>\n\n\n\n
A produ\u00e7\u00e3o de dutos de ar pode ser customizada na planta de beneficiamento. Durante a produ\u00e7\u00e3o de dutos de ar, o ambiente \u00e9 limpo, lofting por computador, corte a laser, baixa perda, podem formar uma opera\u00e7\u00e3o simplificada. O duto de ar formado tem \u00e2ngulos retos de dobra, largura de dobra uniforme e arco uniforme, sem orif\u00edcios, mordidas e defeitos de rachadura. Os dutos de ar s\u00e3o refor\u00e7ados de forma confi\u00e1vel, com espa\u00e7amento adequado e simetria uniforme.<\/p>\n\n\n\n
\nPrecau\u00e7\u00f5es de instala\u00e7\u00e3o<\/strong><\/li>\n<\/ul>\n\n\n\nO duto de ar de flange TDF tem sido amplamente utilizado gradualmente. O desempenho do duto de flange TDF foi reconhecido por muitos usu\u00e1rios, mas h\u00e1 algumas coisas a serem observadas ao instalar o duto de flange TDF, ent\u00e3o vamos apresent\u00e1-lo. Problemas que devem ser observados ao instalar o duto de flange TDF.<\/p>\n\n\n\n
As faces do flange das duas se\u00e7\u00f5es do tubo de ar do flange TDF devem ser coladas com selante antes de conectar os parafusos em cada um dos quatro cantos fortes. Depois disso, os \u00e2ngulos de cisalhamento das quatro faces do flange em ambas as extremidades do duto do flange TDF devem ser precisos, caso contr\u00e1rio, as quatro faces do flange ser\u00e3o desiguais ap\u00f3s o processamento, o que far\u00e1 com que o duto do flange TDF seja torcido e irregular.<\/p>\n\n\n\n
A superf\u00edcie do flange do tubo de ar deve se manter em um \u00e2ngulo reto de 90 graus durante o processo de usinagem. Muito grande ou muito pequeno afetar\u00e1 a qualidade do flange do tubo de ar, como a tor\u00e7\u00e3o e o deslocamento do tubo de ar e os inconvenientes de instala\u00e7\u00e3o e conex\u00e3o. Em seguida, use uma m\u00e1quina dobradeira de flange manual ou uma m\u00e1quina dobradeira hidr\u00e1ulica de chapa met\u00e1lica que corresponda \u00e0 superf\u00edcie do flange do tubo de ar de flange comum, e moldes superiores e inferiores especiais s\u00e3o usados para dobrar a superf\u00edcie de conex\u00e3o do tubo de ar e o flange, caso contr\u00e1rio, afetar\u00e1 a qualidade da superf\u00edcie do flange, como danos na superf\u00edcie do flange e distor\u00e7\u00e3o desigual. <\/p>\n\n\n\n
Os itens acima s\u00e3o os assuntos que precisam de aten\u00e7\u00e3o ao instalar o duto de flange TDF. Ao instalar, certifique-se de seguir as instru\u00e7\u00f5es corretamente para garantir que o desempenho do duto de flange TDF possa ser totalmente demonstrado.<\/p>\n\n\n\n<\/figcaption><\/figure>\n\n\n\nEm resumo, o flange TDF de isolamento t\u00e9rmico interno ducto de ar<\/a> tem grandes vantagens tanto no processamento quanto na instala\u00e7\u00e3o. \u00c9 adequado para sistemas civis de ar condicionado central em grande escala (como est\u00e1dios, centros de exposi\u00e7\u00f5es, centros comerciais, edif\u00edcios comerciais, etc.) e parques tem\u00e1ticos.
