沙市為什么機械密封需要進行沖洗
機(ji)械密封是一種通(tong)用的(de)軸封裝置，密封效(xiao)果好(hao)，可達到介質無(wu)泄露，在普通(tong)泵中一般(ban)可運行1~2年或(huo)更長時間(jian)。用來減(jian)少機(ji)器(qi)的(de)內漏、外漏和穿漏，提高機(ji)器(qi)容(rong)積(ji)效(xiao)率。減(jian)少摩擦損...

機械密封是靠彈性元件(繃簧、波紋管(guan)等) 和(he)密封液體(ti)壓(ya)力在(zai)相對運動的動環和(he)靜環的接觸面(端(duan)(duan)面)上發作一恰當的壓(ya)緊力(比壓(ya))使(shi)兩個(ge)亮光(guang)、 平直的端(duan)(duan)面緊密貼合(he)；端(duan)(duan)面間...
機械密(mi)(mi)封是一(yi)種(zhong)依靠(kao)彈性元件對(dui)動(dong)、靜環端(duan)面密(mi)(mi)封副的(de)預(yu)緊(jin)和介質壓力(li)(li)與彈性元件壓力(li)(li)的(de)壓緊(jin)而達到密(mi)(mi)封的(de)軸向(xiang)端(duan)面密(mi)(mi)封裝置。動(dong)環和靜環的(de)端(duan)面組成一(yi)對(dui)摩擦副，動(dong)環靠(kao)密(mi)(mi)封室中液...
熱水(shui)泵(beng)集式機械密封是指安(an)裝(zhuang)(zhuang)(zhuang)運行在泵(beng)類(lei)設備中(zhong)(zhong)起動(dong)態密封作用(yong)的裝(zhuang)(zhuang)(zhuang)置，避免水(shui)泵(beng)蝸(gua)殼中(zhong)(zhong)的流(liu)(liu)(liu)體(ti)介質通過泵(beng)軸流(liu)(liu)(liu)出。由于(yu)水(shui)泵(beng)多為(wei)輸送(song)流(liu)(liu)(liu)體(ti)介質，具(ju)有水(shui)平安(an)裝(zhuang)(zhuang)(zhuang)、高轉速、高壓力(li)、帶...
