REXROTH柱塞泵現(xiàn)貨銷售
REXROTH柱塞泵工作原理這種結(jié)構(gòu)較簡(jiǎn)單，轉(zhuǎn)速較高，但工作條件要求高，柱塞端部與斜盤的接觸部往往是薄弱環(huán)節(jié)。斜軸式的斜盤軸線與傳動(dòng)軸軸線是一致的。力士樂(lè)REXROTH柱塞泵工作原理根據(jù)傾斜元件的不同，有斜盤式和斜軸式兩種。斜盤式是斜盤相對(duì)回轉(zhuǎn)的缸體有一傾斜角度，而引起柱塞在泵缸中往復(fù)運(yùn)動(dòng)。傳動(dòng)軸軸線和缸體軸線是一致的。REXROTH柱塞泵由于柱塞缸體相對(duì)傳動(dòng)軸傾斜一角度而使柱塞作往復(fù)運(yùn)動(dòng)。流量調(diào)節(jié)依靠擺動(dòng)柱塞缸體的角度來(lái)實(shí)現(xiàn)，故有的又稱擺缸式。它與斜盤式相比，工作可靠，流量大，但結(jié)構(gòu)復(fù)雜。
REXROTH柱塞泵噪聲過(guò)大
1）產(chǎn)生原因：1.吸入管道漏氣；2.吸油不充分；3.泵軸和原動(dòng)機(jī)軸不同心；4.油中有氣泡；5.泵轉(zhuǎn)速過(guò)高；6.泵壓力過(guò)高；7.軸密封處漏氣；8.油液過(guò)濾精度過(guò)低導(dǎo)致葉片在槽中卡住；9.變量泵止動(dòng)螺釘調(diào)整失當(dāng)。
2）排除方法：重新調(diào)接至所需壓力檢查管道各連接處，并予以密封、緊固同前述排除方法重新安裝達(dá)到說(shuō)明書要求精度補(bǔ)充油液或采取結(jié)構(gòu)措施，把回油口入油面以下選用推薦轉(zhuǎn)速范圍降壓至額定壓力以下更換油封拆洗修磨泵內(nèi)臟件并仔細(xì)重新組裝，并更換油液 適當(dāng)調(diào)整螺釘至噪聲達(dá)到正常。
