随着机床自动化的不断发展,液压元件的使用日益广泛,对其性能与质量提出了更高的要求。根据1972年8月大连中低压液压元件会议纪要精神和同年中低压液压元件质量评比中发现电磁阀质量存在的问题,对目前生产的电磁阀,进一步提高和改善其性能与加工质量,是非常必要的。提高电磁阀的性能,主要围绕改善其压力损失、换向可靠性和内外泄漏等方面。特别是外泄漏,已成为必须加以特别重视的问题了。
With the continuous development of machine tool automation, the use of hydraulic components is becoming more and more widespread, and their performance and quality are put forward higher requirements. According to the spirit of meeting summary of mid and low pressure hydraulic components in Dalian in August 1972 and the quality problems of solenoid valves found in mid-low pressure hydraulic components in the same year, it is very necessary to improve and improve the performance and processing quality of the present solenoid valve of. Improve the performance of the solenoid valve, mainly around improving its pressure loss, reversing the reliability and internal and external leakage and so on. In particular, external leakage has become a problem that must be given special attention.
