液壓泵A4VSO500DR/22R-PPB13N00廠家貨源
液壓泵是液壓系統(tǒng)的動(dòng)力元件,是靠發(fā)動(dòng)機(jī)或電動(dòng)機(jī)驅(qū)動(dòng),從液壓油箱中吸入油液,形成壓力油排出,送到執(zhí)行元件的一種元件。液壓泵按結(jié)構(gòu)分為齒輪泵、柱塞泵、葉片泵和螺桿泵
為液壓傳動(dòng)提供加壓液體的一種液壓元件,是泵的一種。它的功能是把動(dòng)力機(jī)(如電動(dòng)機(jī)和內(nèi)燃機(jī)等)的機(jī)械能轉(zhuǎn)換成液體的壓力能。影響液壓泵的使用壽命因素很多,除了泵自身設(shè)計(jì)、制造因素外和一些與泵使用相關(guān)元(如聯(lián)軸器、濾油器等)的選用、試車運(yùn)行過程中的操作等也有關(guān)。
液壓泵的工作原理是運(yùn)動(dòng)帶來泵腔容積的變化,從而壓縮流體使流體具有壓力能。
必須具備的條件就是泵腔有密封容積變化。
常用液壓泵的種類:
1、按流量是否可調(diào)節(jié)可分為:變量泵和定量泵。
輸出流量可以根據(jù)需要來調(diào)節(jié)的稱為變量泵,流量不能調(diào)節(jié)的稱為定量泵。
2、按液壓系統(tǒng)中常用的泵結(jié)構(gòu)分為:齒輪泵、葉片泵和柱塞泵3種。
齒輪泵:體積較小,結(jié)構(gòu)較簡單,對油的清潔度要求不嚴(yán),較便宜;但泵軸受不平衡力,磨損嚴(yán)重,泄漏較大。
葉片泵:分為雙作用葉片泵和單作用葉片泵。這種泵流量均勻、運(yùn)轉(zhuǎn)平穩(wěn)、噪音小、作壓力和容積效率比齒輪泵高、結(jié)構(gòu)比齒輪泵復(fù)雜。
