气缸是气动执行元件中最重要的元件之一,提高气缸的性能,是气动技术领域一项重要的研究课题。衡量双作用气缸性能的主要项目有:起动压力、低压低速性能、泄漏量、耐压能力、缓冲性能,以及耐久性能(或称寿命)等。国产气缸在起动压力、低压低速性能、耐久性能等方面与国外先进水平相比差距很大。近几年我厂作了大量的试验研究和质量攻关,并取得了很大进展,上述几项性能指标已经接近国际先进水平。1.起动压力起动压力是使活塞移动的最低压缩气压力。起动压力的高低,是气缸结构、零件加
The air cylinder is one of the most important components of the pneumatic actuator. Improving the performance of the cylinder is an important research topic in the field of pneumatic technology. The main items that measure the performance of double-acting cylinder are: starting pressure, low pressure and low speed performance, leakage, pressure capacity, cushioning performance, and durability (or life). Domestic cylinder in the starting pressure, low pressure low-speed performance, durability and other aspects of the gap with foreign advanced level. In recent years, I plant a lot of experimental research and quality research, and made great progress, the above several performance indicators have been close to the international advanced level. 1. Starting pressure The starting pressure is the lowest pressure that moves the piston. Starting pressure level, is the cylinder structure, parts plus
