1\u3001Teste de caracter\u00edstica de fluxo da v\u00e1lvula<\/h2>\n\n\n\n

Instale a v\u00e1lvula de teste na posi\u00e7\u00e3o correspondente da tubula\u00e7\u00e3o de acordo com seu tamanho, inicie o conversor de frequ\u00eancia para aumentar sua frequ\u00eancia de acordo com a taxa especificada, a velocidade da bomba aumenta, a diferen\u00e7a de press\u00e3o em ambos os lados da v\u00e1lvula muda de acordo e obtenha o valor de fluxo correspondente ao mesmo tempo. Quando a diferen\u00e7a de press\u00e3o entre os dois lados da v\u00e1lvula atinge sua diferen\u00e7a de press\u00e3o m\u00e1xima ou a frequ\u00eancia operacional atinge 50 Hz, o conversor de frequ\u00eancia desacelera e para automaticamente. Os dados do sensor de fluxo e do sensor de press\u00e3o diferencial foram registrados, e a curva caracter\u00edstica do fluxo de press\u00e3o diferencial foi desenhada para completar o experimento. FIGO. 1 mostra os resultados do teste da curva caracter\u00edstica de fluxo da v\u00e1lvula de equil\u00edbrio de fluxo.<\/p>\n\n\n\n

2\u3001Teste de caracter\u00edstica de abertura de v\u00e1lvula<\/h2>\n\n\n\n

Instale o regulador com atuador na tubula\u00e7\u00e3o, ajuste a abertura da v\u00e1lvula para ajustar o fluxo e controle a diferen\u00e7a de press\u00e3o entre as duas extremidades da v\u00e1lvula em 100kPa para obter a curva caracter\u00edstica de fluxo aberto. Veja a figura 2.<\/p>\n\n\n\n

3\u3001Coeficiente de fluxo da v\u00e1lvula, teste do coeficiente de resist\u00eancia da v\u00e1lvula<\/h2>\n\n\n\n

A diferen\u00e7a de press\u00e3o entre as duas extremidades da v\u00e1lvula de \u00e1gua \u00e9 controlada em 100kPa, e a vaz\u00e3o da v\u00e1lvula \u00e9 medida neste momento. O coeficiente de vaz\u00e3o pode ser obtido usando a f\u00f3rmula (1), e o coeficiente de resist\u00eancia pode ser calculado pela f\u00f3rmula (2), onde V \u00e9 a vaz\u00e3o da tubula\u00e7\u00e3o da v\u00e1lvula, calculada pela f\u00f3rmula (3), e D \u00e9 o di\u00e2metro nominal da v\u00e1lvula. Ap\u00f3s o procedimento acima entrar na op\u00e7\u00e3o de teste, o relat\u00f3rio \u00e9 gerado automaticamente pelo computador.<\/p>\n\n\n\n

4\u3001Teste de regula\u00e7\u00e3o de press\u00e3o da v\u00e1lvula redutora de press\u00e3o e v\u00e1lvula diferencial de press\u00e3o<\/h2>\n\n\n\n

A bancada de testes pode ser usada para testar a press\u00e3o de sa\u00edda e a curva de fluxo e press\u00e3o de entrada do v\u00e1lvula de redu\u00e7\u00e3o de press\u00e3o<\/a>;A diferen\u00e7a de press\u00e3o entre as duas extremidades da v\u00e1lvula de controle de press\u00e3o diferencial e a curva de varia\u00e7\u00e3o da vaz\u00e3o e press\u00e3o de entrada podem ser medidas usando a tabela experimental.<\/p>","protected":false},"excerpt":{"rendered":"
