擺動式液壓缸
擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)式液壓缸是輸出扭矩并實(shi)現(xian)往(wang)復運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的(de)執行元件，有單葉(xie)片(pian)、雙葉(xie)片(pian)、螺(luo)(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)等幾種(zhong)(zhong)形式。葉(xie)片(pian)式式：定子(zi)塊(kuai)固(gu)定在缸體上，而葉(xie)片(pian)和轉(zhuan)(zhuan)子(zi)連接在一起。根據進(jin)油方向，葉(xie)片(pian)將帶(dai)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)子(zi)作往(wang)復擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)。螺(luo)(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)式又分單螺(luo)(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)和雙螺(luo)(luo)旋兩種(zhong)(zhong)，現(xian)在雙螺(luo)(luo)旋比(bi)較常用，靠兩個螺(luo)(luo)旋副降液壓缸內(nei)活塞(sai)的(de)直線(xian)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)變為直線(xian)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)與自(zi)轉(zhuan)(zhuan)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的(de)復he運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)，從而實(shi)現(xian)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)。
③ 從管路進入的異物，有多種情況。
a.清(qing)洗(xi)時(shi)不(bu)注意。管(guan)路安裝好(hao)以(yi)(yi)后進(jin)行(xing)清(qing)洗(xi)時(shi)，不(bu)應通過缸(gang)(gang)體(ti)(ti)，必(bi)須(xu)在缸(gang)(gang)體(ti)(ti)的油口(kou)前(qian)邊加裝旁(pang)通管(guan)路。這一點很重要(yao)。否則，管(guan)路中(zhong)的異(yi)物(wu)(wu)將(jiang)進(jin)入缸(gang)(gang)內(nei)，一旦進(jin)入，即難(nan)以(yi)(yi)向(xiang)外排除，反而變成向(xiang)缸(gang)(gang)體(ti)(ti)內(nei)輸(shu)送(song)異(yi)物(wu)(wu)了。再者，清(qing)洗(xi)時(shi)要(yao)考慮安裝管(guan)路操作中(zhong)所(suo)進(jin)異(yi)物(wu)(wu)的取出方法。此外，對管(guan)內(nei)的腐蝕(shi)等在管(guan)路安裝之(zhi)前(qian)即應進(jin)行(xing)酸洗(xi)等手續，必(bi)須(xu)完(wan)全去掉銹蝕(shi)。
1、液壓缸(gang)內(nei)導向元件摩擦力不均勻(yun)產生(sheng)的低速爬行，建議優(you)先(xian)采用(yong)金(jin)屬(shu)作(zuo)為導向支(zhi)(zhi)撐(cheng)，如ＱＴ５００－７、ＺＱＡＬ９－４等，如采用(yong)非金(jin)屬(shu)支(zhi)(zhi)撐(cheng)環，建議選用(yong)在油液中尺(chi)寸穩定(ding)性(xing)好的非金(jin)屬(shu)支(zhi)(zhi)撐(cheng)環，特別(bie)是熱(re)膨脹系數應小，另外對支(zhi)(zhi)撐(cheng)環的厚度(du)，必須嚴(yan)格(ge)控制尺(chi)寸公差和厚度(du)的均勻(yun)性(xing)。

2、對于密(mi)(mi)(mi)封(feng)(feng)件(jian)材(cai)質問題引起的液壓缸低速爬(pa)行(xing)，建(jian)議在(zai)工況允(yun)許的條(tiao)件(jian)下，優先采(cai)用(yong)以聚(ju)四氟乙烯作(zuo)為(wei)密(mi)(mi)(mi)封(feng)(feng)的組合密(mi)(mi)(mi)封(feng)(feng)圈，如常(chang)用(yong)的格(ge)萊圈、斯特封(feng)(feng)等等；如選唇口(kou)密(mi)(mi)(mi)封(feng)(feng)，建(jian)議材(cai)料優選丁晴(qing)橡(xiang)膠或類似材(cai)料的密(mi)(mi)(mi)封(feng)(feng)件(jian)，其跟(gen)隨性較好。
