引言在火箭推进剂加注过程中,地面设备系统通常很少使用液氢泵输送设备。液氢和液氧不同,绝大部分液氢用挤压的方法从贮存区输送到推进剂贮箱。但是,新的要求促使人们考虑采用增压泵。本文介绍一种液氢输送系统,该系统是以安装在杜瓦瓶内液氢增压泵的设计和研制为基础发展而来的。
INTRODUCTION Ground-based systems often use liquid hydrogen pumping equipment during rocket propellant filling. Liquid hydrogen and liquid oxygen are different, the vast majority of liquid hydrogen by extrusion method from the storage area to the propellant tank. However, new demands have prompted people to consider using booster pumps. This article describes a liquid hydrogen delivery system developed on the basis of the design and development of liquid hydrogen booster pumps installed in dewar.
