1 前言 Ⅰ号泵是我国生产厂家最多、产量最大、应用最广的柴油机高压油泵。Ⅰ号泵的钢球式(本行业通称T7B)调速器恢复性差、许用转速低、操纵力大、加速慢等缺陷是本行业公认的。有的生产厂家与科研院所或高等院校合作,设计试制Ⅰ号泵新型调速器,但其思路局限于模仿A型泵调速器或测绘国外某种调速器,虽然其试制品得到满意的性能,
1 Introduction Ⅰ pump is the largest manufacturer in China, the largest output, the most widely used diesel engine high pressure pump. Ball pump type Ⅰ (T7B commonly known in the industry) governor recovery is poor, permit the use of low speed, large control, slow acceleration and other defects is recognized in the industry. Some manufacturers and research institutes or institutions of higher learning to design trial-size pump new governor, but the idea is limited to imitate the A-type pump governor or map some foreign governor, although its trial products Satisfactory performance,
