摘要

液壓泵是向液壓系統(tǒng)提供一定流量和壓力的油液的動力元件,它是每個液壓系統(tǒng)中不可缺少的核心元件,合理的選擇液壓泵對于液壓系統(tǒng)的能耗﹑提高系統(tǒng)的效率﹑降低噪聲﹑改善工作性能和保證系統(tǒng)的可靠工作都十分重要
本設(shè)計對軸向柱塞泵進(jìn)行了分析,主要分析了軸向柱塞泵的分類,對其中的結(jié)構(gòu),例如,柱塞的結(jié)構(gòu)型式﹑滑靴結(jié)構(gòu)型式﹑配油盤結(jié)構(gòu)型式等進(jìn)行了分析和設(shè)計,還包括它們的受力分析與計算.還有對缸體的材料選用以及校核很關(guān)鍵;最后對變量機(jī)構(gòu)分類型式也進(jìn)行了詳細(xì)的分析,比較了它們的優(yōu)點(diǎn)和缺點(diǎn).該設(shè)計最后對軸向柱塞泵的優(yōu)缺點(diǎn)進(jìn)行了整體的分析,對今后的發(fā)展也進(jìn)行了展望.


關(guān)鍵詞: 柱塞泵,液壓系統(tǒng),結(jié)構(gòu)型式,今后發(fā)展.









Abstract

Liquid's pressing a pump is the motive component of oil liquid which presses system to provide certain discharge and pressure toward the liquid, it is each core component that the liquid presses the indispensability in the system, reasonable of choice liquid's pressing a pump can consume a ﹑ exaltation the efficiency ﹑ of the system to lower a Zao voice ﹑ an improvement work function and assurance system for liquid pressing system of of dependable work all very important
This design filled a pump to carry on toward the pillar to the stalk analytical, mainly analyzed stalk to fill the classification of pump toward the pillar, as to it's win of structure, for example, the pillar fill of the ﹑ slippery Xue structure pattern ﹑ of the structure pattern went together with the oil dish structure pattern's etc. to carry on analysis and design, also include their is analyze by dint with calculation.The material which still has a body to the urn chooses in order to and school pit very key;Finally measure an organization classification towards change, the pattern also carried on detailed analysis and compared their advantage and weakness.That design end filled the merit and shortcoming of pump to carry on whole analysis toward the pillar to the stalk and also carried on an outlook to aftertime's development.


Keyword: The pillar fills a pump, the liquid presses system, structure pattern, will develop from now on.
