A unidade reguladora de press\u00e3o de GNC \u00e9 um dispositivo especial capaz de reduzir automaticamente a press\u00e3o do g\u00e1s transmitido pela conduta industrial at\u00e9 ao n\u00edvel de press\u00e3o necess\u00e1rio.
\nPode reduzir a press\u00e3o mais elevada do g\u00e1s na entrada do equipamento para o valor de press\u00e3o exigido na sa\u00edda do equipamento e pode integrar fun\u00e7\u00f5es de medi\u00e7\u00e3o e odoriza\u00e7\u00e3o, conforme necess\u00e1rio.
\nIntegra regula\u00e7\u00e3o de press\u00e3o, dosagem, filtragem, corte de emerg\u00eancia e liberta\u00e7\u00e3o de seguran\u00e7a.
\nAdequado para g\u00e1s natural, g\u00e1s artificial, g\u00e1s de coque, g\u00e1s de petr\u00f3leo liquefeito, metano e outros gases.
\nO GNV (g\u00e1s natural veicular) comprimido (abaixo de 25 MPa) passa pelo filtro, pela v\u00e1lvula de esfera de alta press\u00e3o e pela v\u00e1lvula de corte de emerg\u00eancia de alta press\u00e3o, entrando no permutador de calor prim\u00e1rio.
\nNo interior do permutador de calor a g\u00e1s para aquecimento, o g\u00e1s, ap\u00f3s o regulador de press\u00e3o prim\u00e1rio, atinge 0,7 ~ 1,2 MPa; ap\u00f3s o permutador de calor secund\u00e1rio e o regulador de press\u00e3o secund\u00e1rio, atinge 0,2 ~ 0,4 MPa (se a press\u00e3o de sa\u00edda for inferior, ocorre uma descompress\u00e3o na terceira fase), entra no medidor de caudal para o c\u00e1lculo do caudal, com descompress\u00e3o em todos os n\u00edveis de press\u00e3o, controlo de temperatura e v\u00e1lvula de corte de emerg\u00eancia, bem como sistema de controlo de interbloqueio.<\/p>\n\n\n<\/colgroup>\n\n\n\n\n\n\n\n\n\n\n

A PRU de GNC (PRMS) pode ser transportada em contentores padr\u00e3o, 20GP, 40GP e 40HQ, com uma boa prote\u00e7\u00e3o fixa no interior do contentor.
\nEmbalagem:
\nSistema principal: A unidade PRU a GNC montada em skid est\u00e1 fixada numa palete de a\u00e7o com amortecedores antivibra\u00e7\u00e3o para absorver os choques durante o transporte. Est\u00e1 envolvida numa pel\u00edcula \u00e0 prova de humidade e numa lona resistente para prote\u00e7\u00e3o contra a chuva, o p\u00f3 e danos mec\u00e2nicos.
\nComponentes de precis\u00e3o: Os reguladores de press\u00e3o, os medidores de caudal e as interfaces homem-m\u00e1quina (HMI) s\u00e3o embalados em caixas imperme\u00e1veis, forradas a espuma e com etiquetagem clara. Isto evita danos nas pe\u00e7as delicadas e simplifica a identifica\u00e7\u00e3o durante a instala\u00e7\u00e3o.
\nAcess\u00f3rios: As mangueiras de alta press\u00e3o, os filtros e as pe\u00e7as sobressalentes s\u00e3o embalados em caixas separadas e etiquetadas, garantindo que todos os componentes estejam presentes no momento da entrega.
\nM\u00e9todos de envio:
\nTransporte em contentores padr\u00e3o: Utiliza contentores 20GP (20 p\u00e9s de uso geral), 40GP (40 p\u00e9s de uso geral) ou 40HQ (40 p\u00e9s de grande capacidade). Este m\u00e9todo \u00e9 econ\u00f3mico, seguro e adequado tanto para o transporte mar\u00edtimo como para o transporte terrestre.
\nSolu\u00e7\u00f5es de transporte personalizadas: No caso de modelos de grandes dimens\u00f5es (por exemplo, 6000 Nm\u00b3\/h), coordenamos com os nossos parceiros de log\u00edstica a utiliza\u00e7\u00e3o de cami\u00f5es de plataforma ou navios de granel, com refor\u00e7os adicionais para fixar o sistema durante o transporte.
\nCoordena\u00e7\u00e3o log\u00edstica: A nossa equipa fornece documenta\u00e7\u00e3o de envio detalhada (lista de embalagem, certificado de origem, documentos de desalfandegamento) e colabora com o utilizador para confirmar os prazos de entrega. Tamb\u00e9m oferecemos orienta\u00e7\u00e3o no local durante a descarga, para garantir um manuseamento seguro do sistema.<\/p>\n
