通山為什么機械密封需要進行沖洗
機械密封是一種(zhong)通(tong)用的(de)軸封裝置,密封效果好,可達到介質無泄(xie)露,在普通(tong)泵(beng)中(zhong)一般可運行1~2年或(huo)更長(chang)時間。用來減少機器(qi)的(de)內漏(lou)(lou)、外(wai)漏(lou)(lou)和穿漏(lou)(lou),提高機器(qi)容積效率。減少摩擦(ca)損(sun)...

機械(xie)密(mi)封包括壓力控制(zhi)、溫(wen)度控制(zhi)、流體替換(堵塞(sai))和雜質去除系(xi)統(tong)。在機械(xie)密(mi)封系(xi)統(tong)中,上述(shu)系(xi)統(tong)并(bing)不(bu)同時包括在內。密(mi)封系(xi)統(tong)的選(xuan)擇主要(yao)取決于主密(mi)封件的應用范圍。例如(ru),如(ru)...
機械(xie)密封利用(yong)機械(xie)方(fang)式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),機械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在(zai)機械(xie)工程中應用(yong)非常廣泛(fan),有多(duo)種形(xing)式,主要包括皮(pi)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿(gan)蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)...
機(ji)械密封是靠彈性元件(繃簧、波紋管(guan)等) 和密封液體壓(ya)力在相對運動的(de)(de)動環和靜環的(de)(de)接觸面(端面)上(shang)發作(zuo)一(yi)恰(qia)當的(de)(de)壓(ya)緊力(比壓(ya))使兩個亮光(guang)、 平直的(de)(de)端面緊密貼合(he);端面間(jian)...
機械密(mi)(mi)封是一種(zhong)依靠(kao)彈性元(yuan)件對(dui)動、靜環端面密(mi)(mi)封副(fu)(fu)的預緊和介質壓力(li)(li)與彈性元(yuan)件壓力(li)(li)的壓緊而達(da)到(dao)密(mi)(mi)封的軸向端面密(mi)(mi)封裝置(zhi)。動環和靜環的端面組(zu)成一對(dui)摩(mo)擦副(fu)(fu),動環靠(kao)密(mi)(mi)封室中液...
熱水(shui)(shui)泵集(ji)式機械密封(feng)是指安(an)裝運行在泵類設備中起動態密封(feng)作用的(de)裝置,避免水(shui)(shui)泵蝸殼中的(de)流(liu)(liu)體介(jie)質通過泵軸流(liu)(liu)出。由(you)于水(shui)(shui)泵多為輸(shu)送流(liu)(liu)體介(jie)質,具有水(shui)(shui)平安(an)裝、高(gao)(gao)轉速、高(gao)(gao)壓力(li)、帶...
