直流继电电磁液压换向阀,是把直流继电器与直流电磁换向阀结合后派生的新型液压元件,本文中简称“继电电磁阀”。这种阀在我厂设计制造后,成功地用于我厂自制的两工位四轴镗床上。实践证明,此类元件不仅是可行的,而且有益于提高电气——液压控制系统的工作可靠性和自动化程度,并降低成本。特别是由于这种结合,产生了新的特点,为设计新颖的电气——液压控制系统提供了新的途径。 DC relay electromagnetic hydraulic valve, the DC relay and DC electromagnetic valve derived from the combination of new hydraulic components, referred to in this paper referred to as “relay solenoid valve.” This valve in our factory design and manufacture, successfully used in our factory-made two-station four-axis boring machine. Practice has proved that such components are not only feasible, but also to improve the work of the electro-hydraulic control system reliability and automation, and reduce costs. Especially due to this combination, new features have emerged that provide new avenues for designing novel electro-hydraulic control systems.
