2.順序閥的應(yīng)用 應(yīng)用順序閥.可以使兩個(gè)以_L的執(zhí)行元件按預(yù)定的順序動(dòng)作。并可將順序閥用作背環(huán)閥、平衡閥、卸荷閥.或用來(lái)保證油路最低工作壓力。 如圖5-19所示為順序動(dòng)作回路，夾具上實(shí)現(xiàn)先定位后夾緊工作順序的液壓控制。油液經(jīng)兩位四通電磁換向閥進(jìn)一入定位缸A下腔.實(shí)現(xiàn)定位動(dòng)作。這個(gè)過(guò)程中，由于壓力未達(dá)到順序調(diào)定值，故夾緊缸不動(dòng)作二待定位完成.油壓升高。達(dá)到順序閥調(diào)定值時(shí)，順序閥開(kāi)啟，油液經(jīng)順序閥進(jìn)入夾緊缸，進(jìn)行夾緊。為保證可靠工作，順序閥調(diào)定壓力值大于定位缸0.5~0.8Mpa。

北京華德液壓A2F28R4P4主油泵 密封破損；(6)鑄鐵泵殼有砂眼或焊接不良。當(dāng)凸輪的凸起部分轉(zhuǎn)過(guò)去后，在彈簧力的作用下，柱塞向下運(yùn)動(dòng)，柱塞上部空間（稱(chēng)為泵油室）產(chǎn)生真空度，當(dāng)柱塞上端面把柱塞套上的進(jìn)油孔打開(kāi)后，充滿(mǎn)在油泵上體油道內(nèi)的柴油經(jīng)油孔進(jìn)入泵油室，柱塞運(yùn)動(dòng)到下止點(diǎn)，進(jìn)油結(jié)束。變量式軸向柱塞泵的斜盤(pán)傾角為零時(shí)稱(chēng)為中位，此時(shí)泵的輸出流量應(yīng)為零。但有時(shí)會(huì)出現(xiàn)中位偏離調(diào)整機(jī)構(gòu)中點(diǎn)的現(xiàn)象，在中點(diǎn)時(shí)仍有流量輸出。其原因是控制器的位置偏離、松動(dòng)或損傷，需要重新調(diào)零、緊固或更換。泵的角度維持力不夠、傾斜角耳軸磨損也會(huì)產(chǎn)生這種現(xiàn)象。(1)機(jī)械振動(dòng)和噪聲變量式軸向柱塞泵的斜盤(pán)傾角為零時(shí)稱(chēng)為中位，此時(shí)泵的輸出流量應(yīng)為零。但有時(shí)會(huì)出現(xiàn)中位偏離調(diào)整機(jī)構(gòu)。 柱塞向一個(gè)方向運(yùn)動(dòng)時(shí)缸內(nèi)出現(xiàn)負(fù)壓，這時(shí)一個(gè)單向閥打開(kāi)液體被吸入缸，柱塞向另一個(gè)方向運(yùn)動(dòng)時(shí)，將液體壓縮后另一個(gè)單向閥被打開(kāi)，被吸入缸內(nèi)的液體被排出，這種工作方式連續(xù)運(yùn)動(dòng)后就形成了連續(xù)供油，1．液壓泵輸出流量不足或不輸出油液實(shí)際上。VDR-11B-2A2-2A3-22 VDR-11B-2A3-2A3-22 VDS葉片泵 VDS系列的葉片泵具有降低動(dòng)力損失的高效運(yùn)行，噪音低，外形小，結(jié)構(gòu)簡(jiǎn)單，操作簡(jiǎn)便， 快速的特性和敏銳的響應(yīng)性，效果高，壽命長(zhǎng)，結(jié)構(gòu)牢固等特點(diǎn)。
