PARKER變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)柱(zhu)塞泵(beng)的(de)(de)(de)壓力油(you)(you)(you)經泵(beng)體(ti)、泵(beng)殼(ke)(ke)變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)殼(ke)(ke)體(ti)中(zhong)(zhong)的(de)(de)(de)通(tong)油(you)(you)(you)孔通(tong)過單向(xiang)(xiang)閥進(jin)入變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)殼(ke)(ke)體(ti)的(de)(de)(de)下(xia)(xia)腔(qiang)(qiang)(qiang),當拉桿(gan)向(xiang)(xiang)下(xia)(xia)運動(dong)(dong)時,推動(dong)(dong)伺服活塞向(xiang)(xiang)下(xia)(xia)移動(dong)(dong),伺服閥的(de)(de)(de)上(shang)(shang)閥口(kou)打開,變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)殼(ke)(ke)體(ti)下(xia)(xia)腔(qiang)(qiang)(qiang)的(de)(de)(de)壓力油(you)(you)(you)經變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)活塞中(zhong)(zhong)的(de)(de)(de)通(tong)油(you)(you)(you)孔進(jin)入變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)殼(ke)(ke)體(ti)上(shang)(shang)腔(qiang)(qiang)(qiang),由(you)于上(shang)(shang)腔(qiang)(qiang)(qiang)面積(ji)大于下(xia)(xia)腔(qiang)(qiang)(qiang),液壓力推動(dong)(dong)活塞向(xiang)(xiang)下(xia)(xia)運動(dong)(dong),帶動(dong)(dong)銷(xiao)軸使變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)頭繞(rao)鋼球中(zhong)(zhong)心旋(xuan)轉,改變(bian)(bian)(bian)(bian)(bian)變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)頭的(de)(de)(de)傾斜角(jiao)(增大),柱(zhu)塞泵(beng)的(de)(de)(de)流量(liang)(liang)隨之(zhi)增大。反之(zhi)拉桿(gan)向(xiang)(xiang)上(shang)(shang)運動(dong)(dong),變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)頭的(de)(de)(de)傾斜角(jiao)向(xiang)(xiang)相反方向(xiang)(xiang)變(bian)(bian)(bian)(bian)(bian)化(hua),泵(beng)的(de)(de)(de)流量(liang)(liang)也隨之(zhi)變(bian)(bian)(bian)(bian)(bian)化(hua)。當傾斜角(jiao)度變(bian)(bian)(bian)(bian)(bian)至(zhi)零以(yi)后,則變(bian)(bian)(bian)(bian)(bian)量(liang)(liang)頭向(xiang)(xiang)負偏角(jiao)方向(xiang)(xiang)變(bian)(bian)(bian)(bian)(bian)化(hua),液流產(chan)生換向(xiang)(xiang),泵(beng)的(de)(de)(de)進(jin)出油(you)(you)(you)口(kou)變(bian)(bian)(bian)(bian)(bian)換。

PARKER變量(liang)柱塞(sai)泵的斜盤(pan)傾角(jiao)為零時(shi)稱為中(zhong)位,此時(shi)泵的輸出流量(liang)應為零。但有時(shi)會出現中(zhong)位偏(pian)離(li)調整機(ji)構中(zhong)點的現象,在中(zhong)點時(shi)仍有流量(liang)輸出。其原因是控制器的位置偏(pian)離(li)、松(song)動或損(sun)傷(shang),需要重新調零、緊固或更換。泵的角(jiao)度(du)維持力不夠、傾斜角(jiao)耳軸磨損(sun)也會產生這種現象。

PARKER變(bian)量(liang)(liang)柱(zhu)塞(sai)泵是(shi)利(li)用與(yu)傳(chuan)動軸(zhou)平(ping)行的(de)柱(zhu)塞(sai)在柱(zhu)塞(sai)孔(kong)(kong)內往(wang)復(fu)運動所產生的(de)容積變(bian)化(hua)來進(jin)行工(gong)作(zuo)的(de)。由于柱(zhu)塞(sai)和柱(zhu)塞(sai)孔(kong)(kong)都是(shi)圓形零件,加(jia)工(gong)時可以達到很高的(de)精度配合,因此具有容積效率高,運轉平(ping)穩,流量(liang)(liang)均勻性好,噪聲低(di),工(gong)作(zuo)壓力高等優點,但對液壓油的(de)污(wu)染(ran)較敏感,結構較復(fu)雜,造價較高。
