|piston compressor/reciprocal compressor;[機]往複式壓縮機;活塞式壓縮機
往複式壓縮機(reciprocating compressor)是一種通過活塞在氣缸内往複運動實現氣體壓縮的機械裝置,屬于容積式壓縮機的一種。其核心結構包括氣缸、活塞、連杆、曲軸、進氣閥和排氣閥等部件。當活塞向氣缸底部移動時,進氣閥開啟,低壓氣體進入氣缸;活塞回程時,氣體被壓縮至設定壓力後通過排氣閥排出。
該設備的工作原理遵循理想氣體定律($PV=nRT$),通過周期性容積變化實現能量轉換。其典型壓縮過程包含吸氣、壓縮、排氣三個階段,壓力範圍通常為0.7 MPa至40 MPa,適用于中小流量高壓場景。熱力學效率可通過等熵壓縮公式計算: $$ eta = frac{T_2 - T1}{T{2s} - T1} $$ 其中$T{2s}$為等熵壓縮終溫。
工業領域主要應用于:
相較于離心式壓縮機,往複式機型具備更高單級壓縮比(可達4:1)和更寬工況適應性,但存在振動較大、維護周期短(每2000-8000小時需檢修活塞環)的局限性。美國能源部數據顯示,優化後的二級往複壓縮機可比單級機型節能15%-20%。
reciprocating compressor 的中文譯名為往複式壓縮機或活塞式壓縮機,是一種通過活塞在氣缸内的往複運動實現氣體壓縮的機械設備。以下是詳細解釋:
如需進一步了解技術參數或具體型號,可參考機械工程手冊或專業詞典(如歐路詞典)。
