長子機械密封的這三個功能一定要了解
機械密封(feng)包括壓力控(kong)制(zhi)、溫度(du)控(kong)制(zhi)、流(liu)體替換(堵塞)和(he)雜質去除系(xi)(xi)統。在機械密封(feng)系(xi)(xi)統中，上(shang)述系(xi)(xi)統并(bing)不(bu)同(tong)時(shi)包括在內。密封(feng)系(xi)(xi)統的選擇(ze)主要(yao)取決于(yu)主密封(feng)件的應用范圍(wei)。例如，如...

機(ji)械密封利用機(ji)械方式傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在(zai)機(ji)械工程中(zhong)應(ying)用非常(chang)廣泛，有多種形式，主要包括皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)...
機械密封(feng)是靠彈性元件(繃簧、波紋管(guan)等) 和(he)密封(feng)液體壓(ya)力在相對(dui)運動(dong)(dong)的動(dong)(dong)環(huan)和(he)靜環(huan)的接(jie)觸(chu)面(mian)(端(duan)面(mian))上發作一(yi)恰當的壓(ya)緊力(比壓(ya))使兩個亮(liang)光、 平(ping)直的端(duan)面(mian)緊密貼合；端(duan)面(mian)間...
機(ji)械密(mi)封(feng)是一(yi)種(zhong)依靠(kao)彈性(xing)元(yuan)件對動、靜(jing)環(huan)(huan)(huan)端面(mian)密(mi)封(feng)副的(de)(de)預緊(jin)和(he)介質壓(ya)力與(yu)彈性(xing)元(yuan)件壓(ya)力的(de)(de)壓(ya)緊(jin)而達(da)到(dao)密(mi)封(feng)的(de)(de)軸向端面(mian)密(mi)封(feng)裝(zhuang)置。動環(huan)(huan)(huan)和(he)靜(jing)環(huan)(huan)(huan)的(de)(de)端面(mian)組(zu)成一(yi)對摩(mo)擦副，動環(huan)(huan)(huan)靠(kao)密(mi)封(feng)室中(zhong)液...
熱水(shui)泵(beng)集(ji)式機械密(mi)封是指安(an)裝(zhuang)運行在泵(beng)類設備中(zhong)起動態(tai)密(mi)封作用的(de)裝(zhuang)置，避免(mian)水(shui)泵(beng)蝸(gua)殼中(zhong)的(de)流(liu)體(ti)介質通(tong)過(guo)泵(beng)軸流(liu)出。由于(yu)水(shui)泵(beng)多為輸送流(liu)體(ti)介質，具有水(shui)平安(an)裝(zhuang)、高轉速、高壓力(li)、帶(dai)...
反壓狀態是不良的工作狀態，介質中的顆粒、雜質很(hen)容易進入密封面(mian)，使密封失效。磨軸的主(zhu)要件為橡膠波(bo)紋管，且由于(yu)上端密封面(mian)處于(yu)不良潤滑狀態，動(dong)靜環(huan)之間的摩擦(ca)力(li)矩大于(yu)橡...
