我们制作了一个手动润滑油泵(附图),安装在C620车床上。对机床导轨和中拖板进行润滑,效果很好。其动作原理是:泵体2内的润滑油(约400厘米~3,可用一个月);通过阀体13上的两个φ4孔进入阀体内,当扳动手柄4时,则推动活塞10上升,阀体内盛油的体积减小,油压增高,推开两个单向阀3的钢 We made a manual lubrication pump (with photos), installed on the C620 lathe. Lubrication of the machine guide rail and the carriage, the effect is very good. Its operating principle is: the lubricating oil in the pump body 2 (about 400 cm ~ 3, available for one month); enters the valve body through two φ4 holes on the valve body 13; when the handle 4 is pulled, the piston 10 is pushed up , The volume of oil in the valve body is reduced, the oil pressure is increased, and the steel of the two check valves 3 is pushed open
