本发明的活塞式油泵结构简单，稳定性好，安装维护方便。
实施例2：
本实施例公开了实施例1所述的微量润滑连续供液系统的工作方法：
空气通过空气压缩机进入储气罐后进入空气过滤器完成调压过滤后，打开球阀，第一气路通过第二快插接头向宝塔接头与油管之间的空间供气，气体通过气管流入喷嘴的气体喷嘴部内；压缩空气进入第二气路，两个信号发生器分别控制两个二位三通电磁阀实现两个第二气路的通断，当二位三通电磁阀打开时，气流经过第二气路进入第二通道部推动活塞压缩弹簧，将油液压入油管，并经过油管进入喷嘴的润滑油喷嘴部，当二位三通电磁阀关闭时，气路无气流，活塞被弹簧弹回，若使两路信号发生器均工作，并且发送脉冲信号间隔半个周期，则第一活 塞式油泵和第二活塞式油泵进气路会分时段产生脉冲气流，第一活塞式油泵和第二活塞式油泵的活塞一个进给一个回弹，使得至少有一个活塞式油泵处于供油状态，两个活塞式油泵的输出油液汇入一个油管内，实现连续持续供油。冷却润滑效果好，满足了大多数基础的润滑供液需求，适用于多种机加工场合。(调油旋钮通过限制活塞行程来调整单次脉冲供油量)，润滑油喷嘴部内的润滑油和气体喷嘴部内的气体在喷嘴内混合，形成高压油雾由喷嘴喷出，实现了气雾润滑方式，可以深入加工表面，保证冷却润滑的稳定性，提高了加工质量。
上述虽然结合附图对本发明的具体实施方式进行了描述，但并非对本发明保护范围的限制，所属领域技术人员应该明白，在本发明的技术方案的基础上，本领域技术人员不需要付出创造性劳动即可做出的各种修改或变形仍在本发明的保护范围以内。
