AI Technical Summary

Technical Problem

In existing reciprocating compressors, the intermediate cavity between the piston assembly and the crankcase causes gas leakage, posing safety risks and economic losses, and failing to meet the requirements for safe, economical, and environmentally friendly operation.

Method used

It employs a gas buffer baffle and a dynamic sealing system, including a gas buffer baffle and a dynamic sealing system integrated on the receiving cylinder body. By monitoring the oil chamber pressure in real time and adjusting the oil pressure, it can effectively recover and seal leaked gas.

Benefits of technology

It significantly improves the safety, economy, and environmental friendliness of the compressor, achieving a low-leakage or even zero-leakage sealing effect, preventing gas from entering the crankcase, and reducing the corrosion of the seals by liquid.

Abstract

本发明公开了一种防泄漏往复式压缩机,属于压缩机领域,包括曲轴箱、气缸组件、接筒组件、气体缓冲隔板和动态密封系统。接筒本体两端分别与气缸组件和曲轴箱密封连接,活塞杆贯穿接筒本体并伸入曲轴箱,接筒本体与活塞杆之间形成油腔。动态密封系统包括油压监测口、油压调节阀和控制器,控制器根据油压监测信号与预设压力的比较结果,调节油压调节阀开度以动态调控油腔油压。气体缓冲隔板设置于接筒本体内,可引导泄漏气体上升回流,防止其下沉凝结。本发明通过气体缓冲隔板与动态密封系统的协同作用,使油腔压力始终处于最佳密封范围,有效防止气体进入曲轴箱,实现了对有毒、有害、易燃易爆及稀有气体的低泄漏甚至零泄漏压缩。
