直流电磁阀是一种连接电气系统和液压系统的电液转换开关式基础件,广泛使用于液压系统中,一般在系统里使用的数量要比其他元件多,特别是自动化程度高的设备更是如此。因此它的性能好坏,寿命长短都直接影响液压系统的可靠性。根据有关规定,要求直流电磁阀除性能可靠外,其寿命在批量产品中要达到800万次以上。目前国内许多液压件制造厂已成批生产的 E_1型干式直流电磁阀,由于结构参数设计和零件制造质量等方面的原因,致使这种元件长期以来存在着漏油、换向可靠性差
DC solenoid valve is a kind of electro-hydraulic switch basic part which connects electric system and hydraulic system. It is widely used in hydraulic system. It is generally used more than other components in the system. Especially the highly automated equipment is in this way. Therefore, its performance is good or bad, the life of a direct impact on hydraulic system reliability. According to relevant regulations, in addition to the requirements of DC solenoid valve reliable performance, its life in the batch of products to reach more than 8 million times. At present, many hydraulic parts manufacturers have batch production of E_1-type dry DC solenoid valve, due to structural parameters of the design and manufacturing quality of parts and other reasons, resulting in long-term existence of such components, oil leakage, poor reliability
