墨脫為什么機械密封需要進行沖洗
機(ji)械密封是一種通用的軸封裝置,密封效(xiao)果(guo)好,可達(da)到介質(zhi)無泄露,在(zai)普通泵中一般可運行1~2年或更長(chang)時間。用來減少(shao)機(ji)器的內漏、外漏和穿漏,提高機(ji)器容積效(xiao)率(lv)。減少(shao)摩(mo)擦損...

機(ji)械密(mi)(mi)(mi)封(feng)包括壓力(li)控制、溫度控制、流體替(ti)換(堵塞)和雜(za)質去除系(xi)統(tong)。在(zai)機(ji)械密(mi)(mi)(mi)封(feng)系(xi)統(tong)中(zhong),上述系(xi)統(tong)并不同時包括在(zai)內。密(mi)(mi)(mi)封(feng)系(xi)統(tong)的選擇主(zhu)要(yao)取決于(yu)主(zhu)密(mi)(mi)(mi)封(feng)件的應(ying)用范(fan)圍。例如,如...
機(ji)械(xie)密封利用(yong)機(ji)械(xie)方式(shi)傳(chuan)(chuan)遞動(dong)(dong)力和運(yun)動(dong)(dong)的傳(chuan)(chuan)動(dong)(dong),機(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)在機(ji)械(xie)工程中應用(yong)非(fei)常廣泛(fan),有多種(zhong)形式(shi),主要(yao)包括皮帶傳(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條傳(chuan)(chuan)動(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)...
機械密封是靠彈(dan)性元件(繃簧、波紋管(guan)等) 和(he)密封液(ye)體壓(ya)(ya)力在相對運動(dong)的動(dong)環和(he)靜環的接觸面(端(duan)(duan)面)上發(fa)作(zuo)一恰當的壓(ya)(ya)緊力(比壓(ya)(ya))使兩個亮光、 平(ping)直的端(duan)(duan)面緊密貼(tie)合;端(duan)(duan)面間...
機械密封(feng)是一種依靠彈(dan)性元件(jian)對動、靜環(huan)端面(mian)密封(feng)副(fu)(fu)的預(yu)緊(jin)和(he)介(jie)質壓(ya)力與彈(dan)性元件(jian)壓(ya)力的壓(ya)緊(jin)而(er)達到密封(feng)的軸向端面(mian)密封(feng)裝置(zhi)。動環(huan)和(he)靜環(huan)的端面(mian)組(zu)成一對摩擦副(fu)(fu),動環(huan)靠密封(feng)室中液...
熱(re)水(shui)泵(beng)集式機械密(mi)封是指安裝運(yun)行在泵(beng)類設備(bei)中(zhong)起動態密(mi)封作用(yong)的(de)裝置,避免水(shui)泵(beng)蝸殼中(zhong)的(de)流(liu)體(ti)介質(zhi)通過泵(beng)軸流(liu)出(chu)。由于水(shui)泵(beng)多為輸送流(liu)體(ti)介質(zhi),具(ju)有水(shui)平安裝、高轉速、高壓(ya)力(li)、帶(dai)...
