五桂山街道為什么機械密封需要進行沖洗
機械(xie)密(mi)封(feng)是一種(zhong)通(tong)(tong)用的軸封(feng)裝置,密(mi)封(feng)效(xiao)果好,可達到介質無泄(xie)露,在(zai)普通(tong)(tong)泵中一般可運行(xing)1~2年或更長(chang)時(shi)間。用來減少機器(qi)的內漏(lou)、外漏(lou)和穿漏(lou),提高機器(qi)容積效(xiao)率(lv)。減少摩擦損...

機械密封包括壓力控(kong)制、溫度控(kong)制、流體替換(huan)(堵塞)和(he)雜質去(qu)除系(xi)統(tong)(tong)。在機械密封系(xi)統(tong)(tong)中,上述(shu)系(xi)統(tong)(tong)并不(bu)同時(shi)包括在內。密封系(xi)統(tong)(tong)的選擇主要取決于主密封件的應用(yong)范(fan)圍。例如,如...
機械(xie)(xie)密封利用機械(xie)(xie)方式(shi)傳(chuan)(chuan)遞動(dong)(dong)力和運動(dong)(dong)的傳(chuan)(chuan)動(dong)(dong),機械(xie)(xie)傳(chuan)(chuan)動(dong)(dong)在機械(xie)(xie)工程中(zhong)應用非常(chang)廣泛,有多(duo)種形式(shi),主要包(bao)括皮(pi)帶傳(chuan)(chuan)動(dong)(dong)、齒輪(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)、齒輪(lun)齒條傳(chuan)(chuan)動(dong)(dong)和螺旋(xuan)傳(chuan)(chuan)動(dong)(dong)...
機械密(mi)封是(shi)靠彈(dan)性(xing)元件(繃簧、波紋(wen)管等) 和(he)密(mi)封液(ye)體壓力(li)在相對運(yun)動的(de)(de)動環和(he)靜環的(de)(de)接觸(chu)面(端(duan)(duan)面)上發作一恰當的(de)(de)壓緊(jin)力(li)(比壓)使兩個亮(liang)光、 平直的(de)(de)端(duan)(duan)面緊(jin)密(mi)貼合;端(duan)(duan)面間(jian)...
機械密(mi)(mi)封(feng)是一種依靠彈性元件(jian)對(dui)動(dong)、靜環(huan)端面密(mi)(mi)封(feng)副的(de)預(yu)緊(jin)(jin)和介質(zhi)壓(ya)力與(yu)彈性元件(jian)壓(ya)力的(de)壓(ya)緊(jin)(jin)而達到密(mi)(mi)封(feng)的(de)軸向端面密(mi)(mi)封(feng)裝置。動(dong)環(huan)和靜環(huan)的(de)端面組成一對(dui)摩(mo)擦副,動(dong)環(huan)靠密(mi)(mi)封(feng)室中液(ye)...
熱(re)水(shui)泵(beng)集式機械(xie)密(mi)封(feng)是指(zhi)安(an)裝運行在泵(beng)類(lei)設(she)備中(zhong)(zhong)起動態(tai)密(mi)封(feng)作用的裝置,避免水(shui)泵(beng)蝸殼中(zhong)(zhong)的流(liu)體介(jie)(jie)質(zhi)通過泵(beng)軸流(liu)出。由(you)于水(shui)泵(beng)多為(wei)輸(shu)送流(liu)體介(jie)(jie)質(zhi),具有水(shui)平安(an)裝、高轉速(su)、高壓力(li)、帶...
