因为这个词汇在英语中并没有明确的定义和意思。请提供更多上下文信息，帮助我更好地理解您的需求。

中文翻译：净正吸入头（是指用于泵的吸入头所需的净正吸入头的最小压力，一般用于计算泵的净正吸入高度和排出高度）

读音：nèi pí shè huī

例句：该泵的NPSh值为3米，意味着该泵运行时需要有3米以上的净正吸入高度，否则无法正常工作。

Translation:

Chinese translation: Net Positive Suction Head (refers to the minimum pressure required for the suction head used in a pump, usually used to calculate the net positive suction height and discharge height of the pump)

Pronunciation: nèi pí shè huī

Example sentence: The NPSh value of the pump is 3 meters, which means that the pump needs to have a net positive suction height of more than 3 meters to operate properly.

npsh通常被翻译为"美国标准软管接头与接咀直管螺纹、净正吸入压头"的意思，还经常被翻译为汽蚀余量，在线读音是[npsh]，npsh在英语中经常以名词形式出现，在《新英汉汉英词典》中，共找到16个与npsh相关的例句。

NPSH的翻译

1.美国标准软管接头与接咀直管螺纹

例句:Tank elevation is to be approx. 3 meters above pump suction for NPSH requirements. (为满足净吸入压头的要求，槽的标高应该大约位于泵进水口3米之上。)

2.净正吸入压头

例句:Tank elevation is to be approx. 3 meters above pum suction for NPSH requirements. (为满足NPSH要求，罐的标高应该大约位于泵进水口3米之上。)

3.汽蚀余量

例句:Tank elevation is to be approx. 3 meters above pum suction for NPSH requirements. (为满足NPSH要求，罐的标高应该大约位于泵进水口3米之上。)

4.净正吸升水头、汽蚀余量

例句:NPSHR - pump NPSH, called NPSH required or moving the pump inlet pressure drop, the smaller the better the performance of anti-cavitation; (翻译:NPSHR――泵汽蚀余量，又叫必须的汽蚀余量或泵进口动压降，越小抗汽蚀性能越好；)

用法及短语

npsh一般作为名词使用，如在necessary NPSH(必需汽蚀余量)、required NPSH(所需的净正吸入压头)、minimum npsh requirement(最小净正吸取水落差要求)等常见短语中出现较多。
