伽師為什么機械密封需要進行沖洗
機械(xie)密封(feng)是一種(zhong)通(tong)用的軸封(feng)裝置,密封(feng)效(xiao)果好,可達到介質無泄(xie)露,在普通(tong)泵(beng)中一般可運行1~2年(nian)或更長(chang)時(shi)間。用來減少(shao)機器的內漏、外(wai)漏和穿漏,提高(gao)機器容積效(xiao)率(lv)。減少(shao)摩擦損...

機(ji)械(xie)密(mi)(mi)封包括壓力控(kong)制、溫度控(kong)制、流體替換(堵塞)和雜(za)質去(qu)除系統(tong)。在(zai)機(ji)械(xie)密(mi)(mi)封系統(tong)中,上述系統(tong)并不同(tong)時(shi)包括在(zai)內。密(mi)(mi)封系統(tong)的選擇(ze)主(zhu)要取決于(yu)主(zhu)密(mi)(mi)封件的應用范圍。例如(ru),如(ru)...
機(ji)械(xie)密封利用機(ji)械(xie)方式(shi)傳遞(di)動(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)的傳動(dong)(dong)(dong)(dong),機(ji)械(xie)傳動(dong)(dong)(dong)(dong)在機(ji)械(xie)工程中應(ying)用非常廣泛,有多種形式(shi),主要(yao)包括皮帶傳動(dong)(dong)(dong)(dong)、齒輪傳動(dong)(dong)(dong)(dong)、鏈傳動(dong)(dong)(dong)(dong)、蝸桿蝸輪傳動(dong)(dong)(dong)(dong)、齒輪齒條(tiao)傳動(dong)(dong)(dong)(dong)和螺旋傳動(dong)(dong)(dong)(dong)...
機(ji)械密封是靠彈性(xing)元件(jian)(繃簧、波紋管等) 和密封液(ye)體(ti)壓力(li)在相對運(yun)動(dong)的(de)(de)動(dong)環和靜環的(de)(de)接觸面(端面)上(shang)發(fa)作一恰當的(de)(de)壓緊力(li)(比壓)使兩個(ge)亮(liang)光、 平直的(de)(de)端面緊密貼合;端面間...
機械密(mi)封(feng)是一種依靠彈性(xing)元(yuan)件(jian)對動(dong)、靜環(huan)(huan)端(duan)面(mian)密(mi)封(feng)副的預緊和介質壓力與彈性(xing)元(yuan)件(jian)壓力的壓緊而達到密(mi)封(feng)的軸(zhou)向(xiang)端(duan)面(mian)密(mi)封(feng)裝(zhuang)置。動(dong)環(huan)(huan)和靜環(huan)(huan)的端(duan)面(mian)組成一對摩擦副,動(dong)環(huan)(huan)靠密(mi)封(feng)室中液...
熱水泵集式機械(xie)密封是指安(an)裝運行在(zai)泵類設備中起動態密封作用(yong)的裝置(zhi),避(bi)免水泵蝸殼中的流(liu)體介質通過泵軸流(liu)出(chu)。由于水泵多(duo)為(wei)輸送流(liu)體介質,具有水平(ping)安(an)裝、高轉速、高壓力、帶...
