Abstract

"MéTODO PARA BOMBEAR LìQUIDO E VAPOR CRIOGêNICOS A PARTIR DE UM TANQUE DE ARMAZENAMENTO E MéTODO E APARELHO PARA BOMBEAR UM FLUIDO CRIOGêNICO A PARTIR DE UM TANQUE DE ARMAZENAMENTO". No presente método e aparelho, líquido e vapor criogênico são bombeados de um tanque de armazenamento e a proporção de líquido e vapor é controlada de modo a influenciar a vazão através do aparelho. Em um curso de indução, o pistão de uma bomba de pistão é retraído e fluido criogênico é aspirado do tanque de armazenamento para o interior de uma câmara de pistão associada com o pistão. A vazão é controlada através do aparelho controlando a proporção de líquido e vapor fornecido à bomba durante o curso de indução fornecendo substancialmente somente vapor à bomba durante uma parte do curso de indução. Em um curso de compressão, a bomba comprime e condensa vapor em líquido e a seguir comprime qualquer líquido no interior da câmara de pistão; fluido criogênico comprimido é finalmente descarregado pela bomba. O aparelho de preferência inclui uma bomba com uma linha adutora de líquido conectando uma entrada da bomba com um tanque de armazenamento, uma linha adutora de vapor contendo um espaço disponível com uma entrada da bomba, uma válvula automaticamente acionada que abre e fecha para controlar o fluxo de vapor para a entrada da bomba, e um controlador que controla a válvula ara realizar uma vazão desejada.
