鐵嶺機械密封的這三個功能一定要了解
機械密(mi)(mi)封包括壓力控(kong)制、溫度控(kong)制、流體(ti)替換(huan)(堵塞)和雜質去除系(xi)統(tong)。在機械密(mi)(mi)封系(xi)統(tong)中,上述系(xi)統(tong)并不同時包括在內。密(mi)(mi)封系(xi)統(tong)的選擇主要取決于主密(mi)(mi)封件的應用范圍。例如,如...

雙端面(mian)小彈簧(huang)平(ping)衡型密封(feng)所(suo)用(yong)摩擦副材料(liao)由(you)動(dong)環和靜(jing)環所(suo)組成的(de)摩擦副是機械(xie)密封(feng)重要的(de)零件,從理(li)論上講,為(wei)了(le)減(jian)少機械(xie)密封(feng)的(de)磨(mo)損量,應(ying)該在合理(li)的(de)動(dong)力流體(ti)潤(run)滑條件下工作運轉...
我們使用(yong)泵過程中總會遇到(dao)密封(feng)膠(jiao)圈損壞(huai)的情況(kuang),一旦損壞(huai)就(jiu)要進行(xing)更(geng)換,作為一個工程技術人(ren)員首先(xian)要分辨(bian)自(zi)己的泵到(dao)底是(shi)哪(na)種型(xing)號,才能購買到(dao)相應口徑的機械密封(feng),由于在市場...
在使用過程中,大多數機械密(mi)(mi)封都屬于(yu)接觸(chu)式密(mi)(mi)封,其機理(li)是靠動密(mi)(mi)封環與靜密(mi)(mi)封環的(de)接觸(chu)端面在密(mi)(mi)封流體壓力和(he)彈性元件壓緊力的(de)作用下緊密(mi)(mi)貼合(he),并相對滑動而達到密(mi)(mi)封。工(gong)作時...
機(ji)(ji)械密封利用(yong)機(ji)(ji)械方式傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong)(dong),機(ji)(ji)械傳(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械工程中(zhong)應用(yong)非常廣(guang)泛,有多種形式,主要(yao)包括皮帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條(tiao)傳(chuan)動(dong)(dong)(dong)(dong)(dong)和螺(luo)旋傳(chuan)動(dong)(dong)(dong)(dong)(dong)...
由于有氣(qi)囊的存在,氮氣(qi)與隔離液(ye)完(wan)全(quan)不接觸,避(bi)免了加壓氣(qi)體(ti)被隔離液(ye)吸收(shou),使(shi)填(tian)料(liao)改集式密封(feng)可以用于液(ye)力透平(ping)等高(gao)壓操作工(gong)況,但是由于隔離液(ye)是在換(huan)熱器的盤管(guan)中流(liu)動,因(yin)此(ci)...
