润滑油及大粘度液体定量输出机构是连杆活塞机构，采用步进电机为动力并与偏心轴相联，偏心轴推动多根互成固定角度连杆、活塞在油缸内往复运动，实现对大粘度液体进行连续定量机械式挤压实现定量输出。
Lube oil and large viscosity liquid quantitative output mechanism is a connecting rod piston mechanism, the use of stepper motor as the power and associated with the eccentric shaft, the eccentric shaft to promote multi-root mutual fixed-angle linkage, reciprocating piston in the cylinder, to achieve large Viscosity liquid continuous quantitative mechanical extrusion to achieve quantitative output.
