high compression ratio pump

基本解释

• [能源科學技術]高壓縮比泵
• [物理學]高壓縮比泵

英汉例句

雙語例句

• As the Roots pump is a non-vacuum inside the compression, the compression ratio is usually very low, so high, medium and vacuum pumps need to pump before.
  由於羅茨泵是一種無內壓縮的真空泵，通常壓縮比很低，故高、中真空泵需要前級泵。
• But there are some shortage of ordinary single-stage heat pump in low-temperature environment, such as high compression ratio, devoid heating power and low efficiency.
  但普通單級空氣源熱泵熱水器在低溫環境下運行中存在壓縮比過大、制熱量不足和制熱傚率太低等問題。
