桑珠孜機械密封的這三個功能一定要了解
機械密封(feng)包括壓力(li)控制、溫度(du)控制、流體(ti)替換(堵(du)塞)和雜質去除系統(tong)。在機械密封(feng)系統(tong)中(zhong),上述(shu)系統(tong)并不同時包括在內(nei)。密封(feng)系統(tong)的(de)選擇主要取決(jue)于主密封(feng)件的(de)應用(yong)范圍(wei)。例(li)如(ru),如(ru)...

雙端面小(xiao)彈簧平衡型(xing)密(mi)(mi)封所用摩擦副材(cai)料由(you)動(dong)環和靜環所組成的摩擦副是機(ji)械密(mi)(mi)封重要的零件(jian),從理論上講,為了減(jian)少機(ji)械密(mi)(mi)封的磨損量,應該在合理的動(dong)力流體潤(run)滑條件(jian)下(xia)工(gong)作運轉(zhuan)...
我們使用泵過(guo)程(cheng)中總會遇(yu)到密封膠圈損壞的(de)情況(kuang),一旦(dan)損壞就要(yao)進行(xing)更換(huan),作為一個(ge)工程(cheng)技術人員首先要(yao)分辨自己的(de)泵到底是哪種(zhong)型號,才能購買(mai)到相應(ying)口徑(jing)的(de)機械密封,由于(yu)在(zai)市(shi)場...
在使用(yong)(yong)過程中(zhong),大多數機械密(mi)(mi)(mi)封(feng)都屬于接(jie)(jie)觸(chu)式密(mi)(mi)(mi)封(feng),其機理是靠動(dong)(dong)密(mi)(mi)(mi)封(feng)環與靜密(mi)(mi)(mi)封(feng)環的接(jie)(jie)觸(chu)端(duan)面在密(mi)(mi)(mi)封(feng)流(liu)體壓(ya)力(li)和彈性元(yuan)件(jian)壓(ya)緊(jin)力(li)的作(zuo)用(yong)(yong)下緊(jin)密(mi)(mi)(mi)貼合,并相對滑動(dong)(dong)而達到密(mi)(mi)(mi)封(feng)。工作(zuo)時(shi)...
機械(xie)密(mi)封利用(yong)(yong)機械(xie)方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong),機械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機械(xie)工程(cheng)中應用(yong)(yong)非(fei)常廣(guang)泛,有多種形式,主要包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺(luo)旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)...
由于有氣囊的(de)(de)存在,氮氣與隔離液完全不接觸,避免了加壓氣體被隔離液吸收,使填料改集式密封(feng)可(ke)以用于液力透平等(deng)高壓操作工況,但是由于隔離液是在換熱器的(de)(de)盤管中流動,因此...
