摘要： A dynamic oil control mechanism for a press including a vacuum inducing ejector or jet-pump to vacuum oil leaking from about an oil seal. The oil seal is located around the drive piston on the press slide to prevent oil migration from the press crown to the die area or slide of the press. A drain port is located about the housing in which the drive piston reciprocates. The ejector maintains a low pressure area within the drain port to pull oil leaking from the seal into the drain port and away from the drive piston. The vacuumed oil is then transferred to an oil reservoir.
摘要翻译： 一种用于压力机的动态油控机构，包括真空诱导喷射器或喷射泵，以从油封上泄漏真空油。 油封位于压机滑块上的驱动活塞周围，以防止油从压力表面移动到模具区域或压机的滑动。 排水口位于驱动活塞往复运动的壳体周围。 喷射器在排水口内保持低压区域，以将油从密封件泄漏到排水口并远离驱动活塞。 然后将抽真空的油转移到储油器。
