目前,在机床设备中使用的柱塞式润滑油泵,皆在进出口上设置两只单向阀,为阀配油泵,这种泵性能欠佳,制造、维修复杂。为此,我们进行了改进,取消了两只单向阀,效果良好。油泵(图1)由泵体、柱塞、弹簧及安装底座组成。泵体为圆柱形,其正中有一柱塞腔,柱塞在其中滑动,与腔径向对称分布有一进油口和一出油口,可安装管接头。柱塞上有一弹簧孔,内装压
At present, the piston pump used in machine tool equipment, both on the import and export set two check valves for the valve with the pump, poor performance of such pumps, manufacturing, maintenance complex. To this end, we made improvements, canceled two check valves, the effect is good. The pump (Figure 1) consists of a pump body, plunger, spring and mounting base. Cylindrical pump body, the middle of a plunger chamber, the plunger sliding in which, radially symmetrical with the chamber has a fuel inlet and a fuel outlet, the pipe can be installed. The plunger has a spring hole, the internal pressure
