Unidades Hidráulicas

Economia e facilidade de implantação

Unidades hidráulicas podem ser entendidas como diversos equipamentos como reservatório de óleo, bombas de deslocamento, válvulas direcionais, válvulas de retenção, atuadores, dentre outros.

A solução WEG de eficiência energética para unidades hidráulicas permite que o motor e a bomba ajustem a rotação conforme a real necessidade da máquina, resultando em economia de energia nos momentos onde o conjunto apenas recircula o fluido hidráulico devido à característica do processo.

A solução consiste na instalação do motor de alta eficiência W22 IR3 Premium ou W22 Super Premium e inversor de frequência CFW11 ou CFW700.

Especificamente para injetoras plásticas, a modulação de velocidade do motor elétrico é realizada através do acesso a um software exclusivo, que pode ser instalado no PLC do inversor de frequência, utilizando os sinais analógicos nativos enviados pelo sistema hidráulico. Nesta condição, a solução de eficiência energética WEG gera economia em praticamente qualquer ciclo de operação, pois em uma máquina desse tipo as exigências do sistema hidráulico variam de acordo com a fase do ciclo (abertura e fechamento de molde, injeção e recalque, resfriamento e dosagem).

 

Benefícios reais da aplicação

  • Economia de energia elétrica de até 60%
  • Fácil implantação com poucos impactos no sistema de produção e na máquina de injeção
  • Replicável a outros sistemas hidráulicos, como prensas, tombadores de caminhão, injetoras de alumínio, etc.
  • Redução da temperatura do fluido hidráulico e consequente menor desgaste dos componentes hidráulicos
