臺州機械密封的這三個功能一定要了解
機(ji)械(xie)密(mi)(mi)封包括壓力控(kong)制(zhi)、溫度控(kong)制(zhi)、流體替換(堵(du)塞)和雜(za)質去除系(xi)統。在(zai)機(ji)械(xie)密(mi)(mi)封系(xi)統中(zhong),上述系(xi)統并(bing)不同(tong)時包括在(zai)內。密(mi)(mi)封系(xi)統的選擇主(zhu)要取決于(yu)主(zhu)密(mi)(mi)封件的應用范圍。例如,如...

雙端面小彈簧平衡(heng)型密封所(suo)用摩擦副(fu)(fu)材料(liao)由(you)動環(huan)和靜(jing)環(huan)所(suo)組成的(de)摩擦副(fu)(fu)是(shi)機械密封重(zhong)要的(de)零(ling)件(jian),從理論上講,為了減(jian)少機械密封的(de)磨損量,應該在(zai)合理的(de)動力流體(ti)潤(run)滑條件(jian)下工作運轉...
我們使用泵過(guo)程(cheng)中總(zong)會遇到密封膠圈損(sun)(sun)壞(huai)的(de)(de)情況(kuang),一旦損(sun)(sun)壞(huai)就要進(jin)行更換(huan),作(zuo)為(wei)一個工(gong)程(cheng)技術人員首先(xian)要分辨(bian)自(zi)己的(de)(de)泵到底是哪種型(xing)號,才(cai)能(neng)購買(mai)到相(xiang)應口(kou)徑的(de)(de)機械密封,由(you)于在市(shi)場(chang)...
在使用過程中,大多數機(ji)械密(mi)(mi)(mi)封(feng)都屬于接(jie)觸式密(mi)(mi)(mi)封(feng),其機(ji)理是靠(kao)動密(mi)(mi)(mi)封(feng)環(huan)與靜密(mi)(mi)(mi)封(feng)環(huan)的接(jie)觸端面(mian)在密(mi)(mi)(mi)封(feng)流體壓力和彈性元件壓緊力的作用下緊密(mi)(mi)(mi)貼合,并相對滑動而達到密(mi)(mi)(mi)封(feng)。工作時(shi)...
機(ji)(ji)械密封(feng)利用機(ji)(ji)械方(fang)式傳(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong),機(ji)(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)在(zai)機(ji)(ji)械工程中應用非常廣(guang)泛,有多種形(xing)式,主(zhu)要(yao)包括(kuo)皮帶傳(chuan)(chuan)動(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)動(dong)(dong)(dong)和螺(luo)旋傳(chuan)(chuan)動(dong)(dong)(dong)...
由于有氣囊的(de)存在(zai)(zai),氮氣與隔(ge)離液(ye)(ye)完全(quan)不(bu)接觸,避免了加壓(ya)氣體(ti)被隔(ge)離液(ye)(ye)吸(xi)收,使填(tian)料(liao)改集(ji)式(shi)密(mi)封(feng)可以用于液(ye)(ye)力透平等高壓(ya)操(cao)作工況,但是(shi)由于隔(ge)離液(ye)(ye)是(shi)在(zai)(zai)換熱器的(de)盤(pan)管中流動,因此...
