Unidades de energia hidr\u00e1ulica PSI<\/span><\/h1>

A PSI utiliza sistemas hidr\u00e1ulicos para controlar nossos trocadores de tela e v\u00e1lvulas de desvio. O sistema hidr\u00e1ulico emprega fluido fechado para transferir energia da unidade de pot\u00eancia hidr\u00e1ulica para o cilindro hidr\u00e1ulico montado na m\u00e1quina e cria um movimento ou for\u00e7a linear. As unidades de energia hidr\u00e1ulica aplicam a press\u00e3o que impulsiona o movimento dos cilindros hidr\u00e1ulicos. Ao contr\u00e1rio das bombas hidr\u00e1ulicas padr\u00e3o, estas unidades de pot\u00eancia utilizam redes de pressuriza\u00e7\u00e3o de v\u00e1rios est\u00e1gios para movimentar o fluido em diferentes cilindros. Alguns dos fatores importantes que influenciam o desempenho de uma unidade de energia hidr\u00e1ulica s\u00e3o os limites de press\u00e3o, a capacidade de pot\u00eancia e o volume do reservat\u00f3rio. Al\u00e9m disso, as caracter\u00edsticas f\u00edsicas, incluindo tamanho, fonte de alimenta\u00e7\u00e3o e for\u00e7a de bombeamento tamb\u00e9m s\u00e3o considera\u00e7\u00f5es importantes. Para compreender melhor os princ\u00edpios operacionais e as caracter\u00edsticas de projeto de uma unidade de energia hidr\u00e1ulica, pode ser \u00fatil observar os componentes b\u00e1sicos de um modelo padr\u00e3o usado em sistemas hidr\u00e1ulicos industriais.<\/p>

As unidades de energia hidr\u00e1ulica PSI s\u00e3o constru\u00eddas para funcionar em condi\u00e7\u00f5es industriais e possuem caracter\u00edsticas de projeto distintas de um sistema de bombeamento t\u00edpico. Os recursos de design padr\u00e3o incluem:<\/p>

Acumuladores (utilizados para sistemas hidr\u00e1ulicos HSC e CSC-BF):<\/u><\/em>\u00a0<\/em>S\u00e3o vasos acoplados aos atuadores hidr\u00e1ulicos. Eles cont\u00eam nitrog\u00eanio pressurizado para ser liberado quando se pretende uma mudan\u00e7a de cilindro extremamente r\u00e1pida.\u00a0<\/p>

Bombas motorizadas (usadas em todos os sistemas hidr\u00e1ulicos PSI:<\/u><\/em> Uma unidade de energia hidr\u00e1ulica pode ser equipada com uma \u00fanica bomba motorizada ou v\u00e1rios dispositivos, cada um com suas pr\u00f3prias v\u00e1lvulas acumuladoras.\u00a0<\/p>

Tanques:<\/u><\/em> O tanque \u00e9 uma unidade de armazenamento projetada com volume suficiente para que o fluido das tubula\u00e7\u00f5es seja drenado para dentro dele. Eles s\u00e3o usados para TODOS os sistemas hidr\u00e1ulicos.<\/p>

Filtros:<\/u><\/em>\u00a0Um filtro normalmente \u00e9 instalado ao longo da parte superior do tanque na linha de retorno para remover o lixo do sistema. Eles s\u00e3o usados para TODOS os sistemas hidr\u00e1ulicos.<\/p>

Controladores de unidade de energia:<\/u><\/em> A unidade do controlador hidr\u00e1ulico \u00e9 a interface do operador que cont\u00e9m interruptores, displays e recursos de monitoramento. \u00c9 necess\u00e1rio para instalar e integrar uma unidade de pot\u00eancia em nossos sistemas hidr\u00e1ulicos e geralmente pode ser encontrado conectado \u00e0 unidade de pot\u00eancia. A PSI normalmente fornece uma caixa de controle eletromec\u00e2nico (ECB) para atua\u00e7\u00e3o manual ou um controlador l\u00f3gico program\u00e1vel (PLC) para atua\u00e7\u00e3o autom\u00e1tica. Eles s\u00e3o usados para TODOS os sistemas hidr\u00e1ulicos com m\u00faltiplos cilindros ou redes de pressuriza\u00e7\u00e3o de m\u00faltiplos est\u00e1gios.<\/p>

V\u00e1lvulas de controle:<\/u><\/em> Diferentes v\u00e1lvulas de controle s\u00e3o montadas na unidade hidr\u00e1ulica para controlar os cilindros hidr\u00e1ulicos. Para cada cilindro necess\u00e1rio para atua\u00e7\u00e3o, \u00e9 necess\u00e1ria uma v\u00e1lvula de controle de dire\u00e7\u00e3o para operar e enviar fluido da unidade de energia hidr\u00e1ulica para o cilindro. O \u201cControlador da Unidade de Pot\u00eancia\u201d seleciona qual v\u00e1lvula de controle operar e permite que o cilindro se estenda ou retraia, dependendo da dire\u00e7\u00e3o selecionada. Eles s\u00e3o usados para TODOS os sistemas hidr\u00e1ulicos.<\/p>

Quando uma unidade hidr\u00e1ulica come\u00e7a a funcionar, acontece o seguinte:<\/span><\/h4>
  1. A energia est\u00e1 ligada.<\/li>
  2. Para uma unidade de pot\u00eancia hidr\u00e1ulica CSC, uma vez que a unidade de pot\u00eancia hidr\u00e1ulica \u00e9 acionada pelo controlador, a bomba de engrenagens puxa o fluido hidr\u00e1ulico para fora do tanque e o move para o cilindro correspondente.<\/li>
  3. Para uma unidade de energia hidr\u00e1ulica HSC, a bomba de engrenagens puxa o fluido hidr\u00e1ulico para fora do tanque e o move para um acumulador depois que a energia \u00e9 ligada. Este processo continua at\u00e9 que a press\u00e3o dentro do acumulador atinja um n\u00edvel predeterminado.<\/li>
  4. Os pressostatos s\u00e3o usados para regular a press\u00e3o do acumulador.<\/li>
  5. Uma vez atingida a press\u00e3o, a unidade est\u00e1 pronta para atua\u00e7\u00e3o imediata. Uma vez que a unidade de energia hidr\u00e1ulica \u00e9 acionada pelo controlador, o acumulador envia fluido hidr\u00e1ulico para fora do tanque (acumulador... n\u00e3o o tanque) e o move para o cilindro correspondente imediatamente para uma mudan\u00e7a r\u00e1pida.<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
