本文分析了ＴＤＢ径向柱塞泵柱塞副及柱塞内腔无效容积引起的功率损失，导出了柱塞配合间隙及柱塞内腔颈部直径两个基本计算公式，它们为柱塞泵尤其是径向柱塞泵的设计提供了新的内容。图２，参４。
This paper analyzes the power loss caused by the plunger pair of TDB radial piston pump and the ineffective volume of the plunger lumen and deduces two basic formulas of the plunger clearance and the neck diameter of the plunger lumen, It is the new design of radial piston pump.
