液壓站組成及工作原理:
液壓站又稱(chēng)液壓泵站,是獨(dú)立的液壓裝置,它按驅(qū)動(dòng)裝置(主機(jī))要求供油,并控制油流的方 向、壓力和流量,它適用于主機(jī)與液壓裝置可分離的各種液壓機(jī)械下。
用戶(hù)購(gòu)買(mǎi)后只要將液壓站與 主機(jī)上的執(zhí)行機(jī)構(gòu)(油缸和油馬達(dá))用油管相連,液壓機(jī)械即可實(shí)現(xiàn)各種規(guī)定的動(dòng)作、工作循環(huán)。 液壓站是由泵裝置、集成塊或閥組合、油箱、電氣盒組合而成。
各部件功用如下:
泵裝置——上裝有電機(jī)和油泵,它是液壓站的動(dòng)力源,將機(jī)械能轉(zhuǎn)化為液壓油的動(dòng)力能。
集成塊——是由液壓閥及通道體組合而成。它對(duì)液壓油實(shí)行方向、壓力、流量調(diào)節(jié)。
閥組合——是板式閥裝在立板上,板后管連接,與集成塊功能相同。
油 箱——是鋼板焊的半封閉容器,上還裝有濾油網(wǎng)、空氣濾清器等,它用來(lái)儲(chǔ)油、油的冷卻 及過(guò)濾。
電器盒 ——分兩種形式。
一種設(shè)置外接引線(xiàn)的端子板;一種是配置了全套控制電器。
液壓站的工作原理如下:
電機(jī)帶動(dòng)油泵旋轉(zhuǎn),泵從油泵中吸油后打油,將機(jī)械能轉(zhuǎn)化為液壓油 的壓力能,液壓油通過(guò)集成塊(或閥組合)被液壓閥實(shí)現(xiàn)了方向、壓力、流量調(diào)節(jié)后經(jīng)外接管路傳 輸?shù)揭簤簷C(jī)械的油缸或油馬達(dá)中,從而控制了液動(dòng)機(jī)方向的變換、力量的大小及速度的快慢,推動(dòng) 各種液壓機(jī)械做功。
液壓站結(jié)構(gòu)形式及主要技術(shù)參數(shù):
液壓站的結(jié)構(gòu)形式,主要以泵裝置的結(jié)構(gòu)形式、安裝位置及冷卻方式來(lái)區(qū)分,按泵裝置的機(jī)構(gòu)
形式安裝位置可分三種:
1、上置立式:泵裝置立式安裝在油箱蓋板上,主要用于定量泵系統(tǒng)一思想
2、上置臥式:泵裝置臥式安裝在油箱蓋板上,主要用于變量泵系統(tǒng),以便于流量調(diào)節(jié)。
3、旁置式:泵裝置臥式安裝在油箱旁單獨(dú)的基礎(chǔ)上,旁置式可裝備備用泵,主要用于油箱容量 大250升,電機(jī)功率7.5千瓦以上的系統(tǒng)。
按站的冷卻方式可分為兩種:
1、自然冷卻:靠油箱本身與空氣熱交換冷卻,一般用于油箱容量小于250升的系統(tǒng)一思想。4WEH22H76/6SG24N9EK4/B10
2、強(qiáng)迫冷卻:采取冷卻器進(jìn)行強(qiáng)制冷卻,一般用于油箱容量大于250升的系統(tǒng)。 液壓站以油箱的有效貯油量度及電機(jī)功率為主要技術(shù)參數(shù)。 油箱容量共有18種規(guī)格(單位:升/L): 25、40、63、100、160、250、400、630、800、1000、1250、1600、2000、2500、3200 、4000、5000、6000 本系列液壓站根據(jù)用戶(hù)要求及依據(jù)工況使用條件,可以做到: 1、按系統(tǒng)配置集成塊,也可不帶集成塊。 2、可設(shè)置冷卻器、加熱器、蓄能器 3、可設(shè)置電氣控制裝,也可不帶電氣控制裝置
