  1. The second chapter simply introduces the development of alternate asynchronous inverter technology and retrospects some types of energy - saving systems for hydraulic elevators. then the working principles of the project are discussed and analyzed at four different working status, i. e. light load upwards, heavy load upwards, light load downwards and heavy load downwards. and the chapter focus on the introduction of structure design of pump station, calculation and type selection of pump / motor reversible units, research on oil leakage principles of accumulator circuit, design of accumulator - pump / motor pressure - energy transformer and integrated valve blocks, etc. the last but not the least, the electrical wiring of vector inverter control cabin and design of computer control and data acquisition system are introduced

    論文第二章首先簡單介紹了交流異步電動機變頻調速技術的發展概況,在回顧電梯液壓控制系統節能技術的基礎上,介紹了本課題研製的「採用蓄能器的液壓電梯變頻節能控制系統研究」的基本原理,分析了動力系統在電梯轎廂輕載上下行、重載上下行等四種典型況下的基本狀態和方式;詳細地介紹了本課題節能系統液壓動力站的結構設計和參數設計,重點研究了液壓動力站的結構設計、液壓馬達可逆性問題及其選型設計計算、蓄能器迴路泄漏油損失機理的研究及其補償裝置的設計、蓄能器-馬達壓力能轉換裝置的設計、多功能集成控制閥組的設計等內;最後簡單介紹了本課題矢控制變頻控制櫃的外部附件電氣接線、計算機控制及數據採集系統的硬體設計等內
  2. The new unit has following technical features : ( 1 ) the unit ' s load is balanced by means of the accumulator and hydraulic cylinder with special structure ; ( 2 ) the installed power of the unit can be reduced greatly by adopting the accumulator ; ( 3 ) variable frequency speed regulation ensures good energy saving effect, and the closed oil circuit requires less hydraulic oil ; ( 4 ) a bi - directional hydraulic lock in the oil circuit ensures the stability and safety of the operation of the pumping unit

    新型機具有4個技術特點: ( 1 )由於活塞柱塞式液壓缸的特殊結構和液壓蓄能器的配合使用,在平衡抽油機大部分載荷時,不需另外增加配重,可減小抽油機體積、質和佔地面積; ( 2 )抽油機下沖程時,與活塞柱塞式液壓缸相連接的蓄能器吸收能,上沖程時儲存在蓄能器中的能補充載荷上行所需的能,大幅度降低抽油機裝機功率; ( 3 )利用變頻積調速節能效率高,閉式油路節省液壓油,同時大大減小液壓站的體積; ( 4 )在閉式油路中採用雙向液壓鎖可使抽油機的啟停更加平穩、迅速,其的穩定性和安全性更好。
