L 型轴向柱塞泵是各种测井仪器的动力源,也可用于类似工况的液压装置中。该泵体积小、重量轻、结构简单、出口压力高、流量小、性能稳定可靠。其结构示意图如图所示。当带动斜盘5的轴转动时,因缸体6固定,斜盘5便推动三个柱塞2在缸体5内往复运动。每个柱塞上有一个返回弹簧2,以保证滑靴4紧压在斜盘5上。当柱塞向背离油缸方向运动时,液压油通过斜盘上的配油槽进入油缸。当
L-type axial piston pump is the power source of a variety of logging instruments, can also be used in similar conditions of the hydraulic device. The pump is small, light weight, simple structure, high outlet pressure, small flow, stable and reliable performance. The structure diagram as shown. When the shaft that drives the swash plate 5 rotates, the swash plate 5 pushes the three plungers 2 to reciprocate in the cylinder 5 due to the fixing of the cylinder 6. A return spring 2 is provided on each plunger to ensure that the shoe 4 is pressed against the swash plate 5. When the plunger moves away from the cylinder, the hydraulic oil enters the cylinder through the oil distribution groove on the swash plate. when
