托喀依鄉機械密封的這三個功能一定要了解
機械(xie)密封(feng)包括壓力控(kong)制(zhi)、溫度控(kong)制(zhi)、流體替換(堵塞)和雜質去除系(xi)(xi)統(tong)。在機械(xie)密封(feng)系(xi)(xi)統(tong)中,上述系(xi)(xi)統(tong)并不同時包括在內。密封(feng)系(xi)(xi)統(tong)的選擇(ze)主要取決于主密封(feng)件的應用范圍。例如,如...

雙(shuang)端面小彈簧平(ping)衡型(xing)密(mi)封(feng)所用摩擦副材料由動環和靜(jing)環所組成的(de)摩擦副是機械(xie)密(mi)封(feng)重要的(de)零件,從理論(lun)上講,為了減(jian)少機械(xie)密(mi)封(feng)的(de)磨損量(liang),應該在合理的(de)動力(li)流體(ti)潤滑條(tiao)件下(xia)工作運轉...
我(wo)們使用泵(beng)過(guo)程中(zhong)總會遇到(dao)密封膠(jiao)圈損壞的情況,一旦損壞就要進(jin)行(xing)更換,作為一個工程技術人員首先要分辨自己的泵(beng)到(dao)底是哪種型號(hao),才(cai)能購買到(dao)相應口徑(jing)的機械密封,由于在(zai)市場...
在(zai)使用過程中,大多數機械(xie)密(mi)(mi)(mi)封(feng)都屬于接(jie)觸式密(mi)(mi)(mi)封(feng),其機理(li)是靠動密(mi)(mi)(mi)封(feng)環與靜密(mi)(mi)(mi)封(feng)環的接(jie)觸端面在(zai)密(mi)(mi)(mi)封(feng)流體壓力和(he)彈性元件壓緊(jin)力的作用下(xia)緊(jin)密(mi)(mi)(mi)貼(tie)合,并相(xiang)對滑(hua)動而(er)達到密(mi)(mi)(mi)封(feng)。工作時(shi)...
機械(xie)(xie)密(mi)封利(li)用(yong)機械(xie)(xie)方式(shi)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),機械(xie)(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械(xie)(xie)工程中應用(yong)非(fei)常(chang)廣(guang)泛,有多(duo)種形(xing)式(shi),主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)(gua)桿蝸(gua)(gua)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)...
由于有氣(qi)囊的(de)存在(zai),氮氣(qi)與隔(ge)離液(ye)(ye)完全(quan)不(bu)接(jie)觸,避(bi)免了加壓氣(qi)體被隔(ge)離液(ye)(ye)吸收,使填料改集(ji)式密封可以用于液(ye)(ye)力透平等高壓操作(zuo)工況,但是(shi)由于隔(ge)離液(ye)(ye)是(shi)在(zai)換熱器的(de)盤管中流動,因此...
