O que \u00e9 uma torre de resfriamento?<\/h2>\r\n\r\n\r\n\r\n\r\nUma torre de resfriamento \u00e9 um grande recipiente que cont\u00e9m um grande ventilador que sopra ar atrav\u00e9s da unidade. A \u00e1gua, incluindo o excesso de calor do sistema HVAC, entra no topo da torre de resfriamento, onde a \u00e1gua flui por v\u00e1rias placas de fluxo at\u00e9 a bacia da torre de resfriamento. \u00c0 medida que a \u00e1gua passa para o fundo, o ar \u00e9 puxado atrav\u00e9s das placas e sobre a \u00e1gua, e o calor \u00e9 retirado por evapora\u00e7\u00e3o. A partir de ent\u00e3o, a \u00e1gua fria ser\u00e1 bombeada de volta para o sistema HVAC, pronta para coletar mais calor.\r\n\r\n\r\n\r\n\r\n\r\nGrandes torres de resfriamento s\u00e3o normalmente instaladas em usinas de energia e outras instala\u00e7\u00f5es industriais, e vers\u00f5es menores s\u00e3o frequentemente vistas em telhados de shopping centers, hospitais e grandes edif\u00edcios comerciais, fornecendo resfriamento ao sistema HVAC.\r\n\r\n\r\n\r\n\r\n

O que s\u00e3o v\u00e1lvulas de torre de resfriamento?<\/h2>\r\n\r\n\r\n\r\n\r\nAs v\u00e1lvulas da torre de resfriamento s\u00e3o dispositivos projetados para controlar, regular, distribuir e permitir ou impedir a passagem de \u00e1gua atrav\u00e9s de certas partes do sistema da torre de resfriamento. As diferentes v\u00e1lvulas em um sistema de torre de resfriamento desempenham um papel importante em seu desempenho e na opera\u00e7\u00e3o geral de suas instala\u00e7\u00f5es. Os tipos de v\u00e1lvulas necess\u00e1rias depender\u00e3o da capacidade de vaz\u00e3o e do tamanho da tubula\u00e7\u00e3o na torre de resfriamento.

          1. Remove Scale Deposits\r\nBecause cooling towers work using evaporation, there is a build-up of scale deposits, which has to be removed regularly. These deposits are caused by the minerals in the water and can vary in severity according to the minerals that are present in the water you are using. Limescale, for example, can build up and decrease both the efficiency and performance of your system. When left unchecked, it can even lead to the premature deterioration of your system.<\/li>\r\n \t
          2. Keep Air Flow Running\r\nSystem breakdowns are often caused by poor fan performance. Loose parts, improper fan alignment, and lack of gearbox maintenance can all result in poor airflow and air that is not sufficiently cooled. Using a tower vacuum, we can remove the contaminants and help you restore proper air flow to your cooling tower. You can also choose to add a biocide to reduce algae and bacterial growth in the cooling tower.<\/li>\r\n \t
          3. Keep the Tubes Clean\r\nChiller tubes can become contaminated with mud, slime, algae, and scale. This can lead to partially or totally clogged tubes. Your water quality and rate of build-up will determine how often you need to clean your tubes. All units experience build-up, and Cleaning tubes regularly is the most efficient way to remove debris. Chiller tubes play a vital role in overall cooling tower maintenance.<\/li>\r\n \t
          4. Inspect Your Water Pump\r\nYou can save on your monthly energy bills by making the pumping process as efficient as possible. Your pump is essential for moving water back and forth, and a well-maintained one goes a long way toward an optimized and better-performing system. Part of the service may include the lubrication of the pump, motor bearings, and the water seal. Alignment checks are also included.<\/li>\r\n \t
          5. Treat Your Water\r\nWater quality is an important part of maintaining the efficiency of your cooling tower. Quality problems can lead to scum and scale build-up. Test and treat your water to prevent premature system issues. Water treatment is a worthwhile investment, as it will help keep your system running at peak performance levels. Cooling tower maintenance also makes water treatment more effective.<\/li>\r\n<\/ol>\r\n","link":"https:\/\/zecovalve.com\/pt\/tag\/valves-maintenance-for-industrial-cooling-towers","name":"Manuten\u00e7\u00e3o de V\u00e1lvulas para Torres de Resfriamento Industriais","slug":"valves-maintenance-for-industrial-cooling-towers","taxonomy":"post_tag","meta":[],"yoast_head":"\nValves Maintenance for Industrial Cooling Towers - Cooling Tower Valves<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/pt\/tag\/valves-maintenance-for-industrial-cooling-towers\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Valves Maintenance for Industrial Cooling Towers - Cooling Tower Valves\" \/>\n<meta property=\"og:description\" content=\"GET COOLING TOWER VALVE PRICE What is a Cooling Tower? A cooling tower is a big vessel that contains a large fan blowing air through the unit. Water including excess heat from the HVAC system is entered at the top of the cooling tower where the water flows down several flow plates to the cooling tower basin. As the water passes to the bottom, the air is pulled through the plates and over the water, and heat is withdrawn through evaporation. Hereafter the cold water to pumped back to the HVAC system ready to collect more heat. Large cooling towers are typically installed on power plants and other industrial facilities and smaller versions are often seen on rooftops of shopping centers, hospitals, and large commercial buildings providing cooling to the HVAC system. What is Cooling Tower Valves? Cooling tower valves are devices designed to control, regulate, distribute, and allow, or disallow the passage of water through certain parts of the cooling tower\u2019s system. The different valves throughout a cooling tower system play an important role in their performance and the overall operation of your facility. The types of valves needed will depend on the flow capacity and the size of the piping in the cooling tower. Temperature and pressure are also critical considerations when it comes to valve selection. Types of Cooling Tower Valves Cooling Towers with Pressure Independent Control (PICV) The PICV will react to system pressure changes and regulate the flow of water to the required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads. Cooling Towers with Automatic Balancing (ABV) The automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to the required max. flow helping the system to be accurately controlled even with pressure changes. This solution is recommended to be installed with a separate control valve. Features of Cooling Tower Valves Simple and reliable design Low head loss Heavy duty cast iron body and stainless steel valve stem Available in the capacity range from 300 to 2200 CMH Size range 150 NB to 500 NB Special protective coatings available for corrosive atmosphere Valves Maintenance for Industrial Cooling Towers Remove Scale Deposits Because cooling towers work using evaporation, there is a build-up of scale deposits, which has to be removed regularly.
