Bombas de engrenagem para aplica\u00e7\u00f5es de extrus\u00e3o de pol\u00edmeros:\u00a0<\/span><\/p>

  • Medidor de controle para menos de +\/-0.25% (t\u00edpico)!\u00a0\u00a0<\/span>As bombas de engrenagem compensam quase inteiramente os efeitos da varia\u00e7\u00e3o da press\u00e3o da cabe\u00e7a. A efici\u00eancia de bombeamento \u00e9 tipicamente 99.5% ou melhor.<\/li>
  • Redu\u00e7\u00e3o de at\u00e9 50:1 na entrada da matriz p<\/span>balan\u00e7os de seguran\u00e7a!\u00a0<\/span>Dimens\u00f5es precisas e repet\u00edveis em todo o seu perfil por meio de sa\u00edda volum\u00e9trica constante (cc\/rev). As oscila\u00e7\u00f5es de press\u00e3o da matriz s\u00e3o normalmente mantidas em 0,5 -1%. No entanto, sem uma bomba de engrenagem, a extrusora pode gerar oscila\u00e7\u00f5es de press\u00e3o da matriz de 10-15%.\u00a0 \u00a0\u00a0<\/li>
  • Use mais recupera\u00e7\u00e3o \u2013 muito mais.\u00a0<\/span>Bombas de engrenagem PSI flatline\u00a0<\/span>uma grande quantidade de impulso do barril da extrusora, uma vez que assumem a fun\u00e7\u00e3o de constru\u00e7\u00e3o de press\u00e3o para o molde.<\/span><\/li>
  • Aumente a produ\u00e7\u00e3o da sua extrusora \u2013 fornecemos ganhos superiores a 25%!\u00a0<\/span>diminuindo a contrapress\u00e3o da extrusora. Exemplo<\/em>:<\/li><\/ul>

    Se sua m\u00e9dia\u00a0taxa de linha \u00e9\u00a0<\/span>2.000 lbs.\/h., um aumento na produ\u00e7\u00e3o de 10% (nosso ganho m\u00ednimo t\u00edpico<\/em>) rende 200 libras\/h. de produ\u00e7\u00e3o agregada. Mais de 5.000 horas de produ\u00e7\u00e3o por ano, o aumento soma 1.000.000 libras. de produto adicional dispon\u00edvel para venda<\/strong>! Tente multiplicar isso pelo seu lucro por libra!\u00a0<\/span><\/p>

    • Menor custo do produto!<\/span>\u00a0Menos desperd\u00edcio de material devido \u00e0 extrus\u00e3o de toler\u00e2ncia mais apertada.<\/li>
    • Corte a sucata!\u00a0 <\/span>Produ\u00e7\u00e3o consistente e estabilidade dimensional significam produtos mais vend\u00e1veis para manter seus valiosos clientes satisfeitos, menos fora das especifica\u00e7\u00f5es e menos refugo.\u00a0\u00a0<\/li>
    • Aumenta a vida \u00fatil do seu <\/span>componentes da extrusora<\/strong> uma vez que a bomba retira a carga de press\u00e3o da extrusora. Tambores, parafusos, rolamentos, caixas de velocidades duram mais!<\/li>
    • Economiza energia!<\/span>\u00a0A adi\u00e7\u00e3o de uma bomba normalmente reduz toda a carga de amperagem de linha.

            \u201cOperamos um sistema de controle de extrus\u00e3o e adicionamos uma bomba de fus\u00e3o<\/b>.\u00a0<\/p>

              1. Nossas matrizes e materiais criam altas contrapress\u00f5es.

                Pense nisso \u2013 pequenas mudan\u00e7as na densidade de fus\u00e3o de dois fornecedores de materiais diferentes (ou mat\u00e9rias-primas de recupera\u00e7\u00e3o misturadas) com o mesmo \u00edndice de fus\u00e3o podem prejudicar o peso por comprimento em um sistema gravim\u00e9trico.
