摘要：液压缸在设计上根据结构特点，设计的零件需要选用不同的材质。液压缸生产过程中，为了保证产品质量，需要严格控制生产过程中的多余物，特别是在零件组装前，对零件进行清洗的工序尤为重要。小批量生产时，经常采用人工操作的方法，对液压缸的各个零件逐一进行清洗检查。当液压缸进入批量生产后，开始向自动化清洗方向发展，因为场地条件、成本控制等多种条件限制下，需要对不同材质的液压缸零件进行混合清洗，而一种清洗剂往往只能适应一类材质的清洗要求，对于不同类型的材质会出现异常的锈蚀问题。该文通过对在制的产品零件进行材质分析和清洗剂以及过程控制参数的研究试验，有效地解决了27SiMn等含Si元素合金钢零件与45#钢零件混合清洗发生腐蚀的问题。

（Beijing Long March Tianmin High-tech Co., Ltd., Beijing100023, China）

Abstract: In the design of hydraulic cylinder, according to the structural characteristics, the parts need to choose different materials. In the production process of hydraulic cylinder, in order to ensure the product quality, it is necessary to strictly control the surplus in the production process, especially before the assembly of parts, the cleaning process of parts is particularly important. In small batch production, manual operation is often used to clean and inspect each part of hydraulic cylinder one by one. When the hydraulic cylinder enters the mass production, it begins to develop to the direction of automatic cleaning. Because of the limitations of site conditions, cost control and other conditions, it is necessary to carry out mixed cleaning for hydraulic cylinder parts of different materials, and a kind of cleaning agent can only adapt to the cleaning requirements of one type of material, and there will be abnormal corrosion problems for different types of materials. In this paper, through the material analysis of in-process parts and the research and test of cleaning agent and process control parameters, the corrosion problem of 27SiMn and other alloy steel parts containing Si element and 45# steel parts mixed cleaning is effectively solved.

Abstract: Proportional solenoid valve is widely used in pneumatic system. Its working principle is to adjust the input gas flow continuously and proportionally according to the input electrical signal. The working characteristics of the proportional electromagnet, the key component of the valve, play a decisive role in the whole valve.
