         In two stroke engines having scavenging pump located at the end,the effect of the revolving inertia force of the scavenging pump is sometimes used in conjuction with attached balance weights on the main cranks to balance the centrifugal couple of the engine.Such a method is nothing new and actual examples can be found on engines built by Pyeckuǖ- and Sulzer.But when asked by the students that how should such a problem be tackled in a general way,the author failed to find out any published articl...
            利用端置式扫气泵来平衡二冲程发动机的离心力偶,并不是一个新颖的问题,在苏联及瑞士 Sulzer 等厂所制的一些发动机中很早已经使用.不过,这种平衡法的一般解法如何,在文献中尚少论及.笔者在带领同学实习时,曾经碰到过这个问题,后来经过思索及分析,得到了一些概念,本文所要谈的,就是这种平衡法的一般解法.

         In this paper a mathematical formula for the design of swivel plate of axial plunger pumps with inclined plunger and returning mechanism, is devived. The paper discusses, in terms of the design of the plate, how to select the structural parameters of the pump so as to obtain the optimum design of the returning mechanism. Finally, the paper points out the necessity of making analysis of the error in structural dimensions of the pump.

         This paper theoretically analyzes the hydraulic system of the well-drilling machine and concIudes that the suction head of the muddy pump is used up by the drawdwn of the suction surface inside the drilling pipe due to density difference of the drilling mud with cuttings and the muddy water, the geometric installation height of the pump velocity head difference of drilling mud, and the total pipe losses at the suction side of the pump. This conclusion provides a primary theoretical basis f...
            本文对液力系统进行了理论分析。阐明了泵的吸程消耗在由于泥浆重度差引起的钻杆内吸水面的下降值,泵的几何安装高度,泥浆速度头的差值,泵吸入侧的全部管路损失,从而为液力系统参数的选取及钻进效率的计算提供了初步的理论依据。样机在松散层试验钻深达205米。在200米处的钻进效率为3.3米/小时。在200米内的平均效率为5~6米/小时。实测所得效率曲线是钻头钻取能力与液力系统排渣能力的综合反映。提高钻进效率的措施,在表层主要是加大钻压、增加钻头刀刃的后角,在深层主要是增加泵的吸程、加大钻杆内径。论证了存在管内液流最佳流速的必然性。
