機械(xie)密(mi)封(feng)包括(kuo)壓力控制、溫(wen)度控制、流體替(ti)換(堵(du)塞)和雜質去除系(xi)(xi)統(tong)。在機械(xie)密(mi)封(feng)系(xi)(xi)統(tong)中(zhong)，上述系(xi)(xi)統(tong)并不同時包括(kuo)在內(nei)。密(mi)封(feng)系(xi)(xi)統(tong)的(de)選擇主(zhu)要取決(jue)于主(zhu)密(mi)封(feng)件的(de)應用范(fan)圍。例如(ru)(ru)，如(ru)(ru)...
雙(shuang)端面小(xiao)彈簧平衡型密(mi)封所(suo)用摩擦副材料由動環和(he)靜(jing)環所(suo)組成的(de)摩擦副是機械密(mi)封重要的(de)零件(jian)，從(cong)理(li)論上(shang)講，為了減少機械密(mi)封的(de)磨損量，應該在(zai)合(he)理(li)的(de)動力流體潤滑條(tiao)件(jian)下工作運轉...
我們使用泵過程(cheng)中總會遇到(dao)密(mi)封膠圈(quan)損壞的(de)情況，一旦損壞就要進行更換，作為(wei)一個(ge)工程(cheng)技術人員首先(xian)要分辨自己的(de)泵到(dao)底(di)是(shi)哪種型(xing)號，才能購買到(dao)相(xiang)應口徑的(de)機械密(mi)封，由(you)于(yu)在市場...
在(zai)使(shi)用(yong)過程中，大多(duo)數機械(xie)密(mi)(mi)封(feng)都屬(shu)于接觸式密(mi)(mi)封(feng)，其機理是靠動密(mi)(mi)封(feng)環(huan)與靜密(mi)(mi)封(feng)環(huan)的(de)接觸端面在(zai)密(mi)(mi)封(feng)流體壓(ya)(ya)力和彈性元件壓(ya)(ya)緊(jin)力的(de)作(zuo)用(yong)下緊(jin)密(mi)(mi)貼合，并相對滑動而達(da)到(dao)密(mi)(mi)封(feng)。工作(zuo)時...
機(ji)械(xie)(xie)密(mi)封(feng)利用機(ji)械(xie)(xie)方式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)(xie)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)械(xie)(xie)工(gong)程中應用非常廣(guang)泛，有(you)多種(zhong)形式，主要包(bao)括皮(pi)帶傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)...
由于有氣(qi)囊的存在，氮氣(qi)與隔離(li)液完全不接觸(chu)，避免了(le)加(jia)壓氣(qi)體被(bei)隔離(li)液吸(xi)收，使(shi)填料(liao)改集式密(mi)封可以用(yong)于液力透平等高壓操作工況(kuang)，但是由于隔離(li)液是在換熱器的盤管中(zhong)流動，因此...
