摘  要

乳化液泵站是用來向綜采工作面液壓支架或高檔普采工作面單體液壓支柱等輸送高壓乳化液的設備，是機械化采媒工作面的主要裝備之一。它是一種把機械能轉變為液壓能的能量轉換裝置。所以說，乳化液泵站是液壓支架的動力源，它的好壞直接影響著液壓支架的工作性能和使用效果。在實際工程中常用的液壓泵有齒輪泵、葉片泵、螺桿泵和柱塞泵。其中柱塞泵是可以得到高壓力、大流量的泵型之一。
論述了乳化液濃度自動配比的意義,針對目前的配比方法,根據理論分析和試驗研究的基礎上,提出了一種能滿足液壓支架等設備使用要求的新型乳化液自動配比裝置。隨著煤礦對乳化液濃度的要求提高，以及提高生產率的要求，以前的人工配液的方式已經不能滿足實際生產的需求了，本裝置就是為此而設計的。
總之，這套裝置能很好的完成配比和及時補充乳化液的要求，對乳化液泵站及整個液壓系統的正常工作起到了很好的保障作用。
關鍵詞： 乳化液泵站； 配比濃度； 自動配比

ABSTRACT

It was mechanization pluck intermediary working face 'mostly fitted among out that emulsion pump station.The equip ment of the emulsion pump station be intended to put together pluck working face hydraulic support or top grade universal pluck working face monomer hydraulic prop wait transportation High Voltage solution. it was a sort of do with mechanical energy translate hydraulic energy 'energy conversion device.So said，emulsion pump station is hydraulic support' power supply，its stand or fall direct influence  hydraulic support double-shift work performance and validate fruit. Hgdraulic pumps has gear pump, vane pump, screw pump and piston pump are often used in practical using, and among of which piston pump is one type of pumps with higher pressure and larger delivery.
The article discusses the meaning of automatic formulating of emulsion concent ration , int roduces a new emulsion automatic formulating device satisfying the requirement s of equipment such as hydraulic supports in view of the present formulating methods and on the basis of theoretical analysis and experimental studies. The demand for improving and boosting productivity with the requisition for density of the emulsion of the colliery, the artificial way to mix the liquid in the past can’t already meet the demand produced actually, this device is designed for this.
In a word, the completion maching and supplementing the demand for the emulsion in time that this set of devices can be very good, play a very good guarantee arrivesing role to the normal work of the pump station of the emulsion and the whole hydranlic pressure system.
Keywords： emulsion pump station; compounding concentration; automatic formulating.
