井研機械密封的這三個功能一定要了解
機械(xie)密封包(bao)括壓(ya)力控(kong)制、溫度控(kong)制、流體替換(堵塞)和雜質去除系統(tong)(tong)。在(zai)機械(xie)密封系統(tong)(tong)中(zhong)，上述(shu)系統(tong)(tong)并不同時包(bao)括在(zai)內。密封系統(tong)(tong)的(de)選擇(ze)主(zhu)要(yao)取決(jue)于主(zhu)密封件的(de)應用范圍。例如(ru)，如(ru)...

機(ji)械密封利用(yong)機(ji)械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動力和運動的傳(chuan)(chuan)(chuan)(chuan)(chuan)動，機(ji)械傳(chuan)(chuan)(chuan)(chuan)(chuan)動在機(ji)械工程中應(ying)用(yong)非常廣泛，有多(duo)種(zhong)形(xing)式，主要包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動和螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動...
機械密封是靠彈性元件(繃簧(huang)、波(bo)紋管(guan)等) 和(he)密封液體(ti)壓力在(zai)相對運動(dong)的動(dong)環和(he)靜環的接(jie)觸面(mian)(端(duan)面(mian))上發作(zuo)一(yi)恰當的壓緊(jin)力(比壓)使兩個亮光、 平(ping)直(zhi)的端(duan)面(mian)緊(jin)密貼合；端(duan)面(mian)間...
機械密(mi)封(feng)(feng)是一種依(yi)靠彈性元件對動(dong)、靜環端(duan)(duan)面密(mi)封(feng)(feng)副的預緊和介質壓力與彈性元件壓力的壓緊而(er)達到密(mi)封(feng)(feng)的軸向(xiang)端(duan)(duan)面密(mi)封(feng)(feng)裝置(zhi)。動(dong)環和靜環的端(duan)(duan)面組(zu)成一對摩擦副，動(dong)環靠密(mi)封(feng)(feng)室中液...
熱水(shui)泵集式機械密封是指安(an)裝(zhuang)運(yun)行在泵類設備(bei)中起(qi)動態(tai)密封作(zuo)用的裝(zhuang)置，避免(mian)水(shui)泵蝸殼(ke)中的流體介(jie)質(zhi)通(tong)過(guo)泵軸(zhou)流出(chu)。由于水(shui)泵多為輸送流體介(jie)質(zhi)，具有(you)水(shui)平安(an)裝(zhuang)、高轉速、高壓力、帶...
反(fan)壓狀(zhuang)態(tai)是不良的(de)(de)工作狀(zhuang)態(tai)，介質中的(de)(de)顆粒(li)、雜質很容(rong)易進入密(mi)封(feng)面，使密(mi)封(feng)失效。磨軸的(de)(de)主要件為橡膠波(bo)紋管，且由于上(shang)端(duan)密(mi)封(feng)面處于不良潤(run)滑狀(zhuang)態(tai)，動靜環之間的(de)(de)摩擦力矩(ju)大于橡...
