平橋機械密封的這三個功能一定要了解
機械密封(feng)包(bao)括(kuo)(kuo)壓力控制、溫(wen)度控制、流(liu)體替換(huan)(堵塞)和(he)雜質去(qu)除系統。在(zai)機械密封(feng)系統中,上述系統并不同時包(bao)括(kuo)(kuo)在(zai)內。密封(feng)系統的(de)選擇主要(yao)取決于(yu)主密封(feng)件的(de)應用(yong)范圍。例如(ru),如(ru)...

雙(shuang)端面小(xiao)彈(dan)簧平衡型密封(feng)所用摩(mo)擦(ca)副材料由(you)動環和靜環所組成的(de)摩(mo)擦(ca)副是機械密封(feng)重(zhong)要的(de)零(ling)件,從理(li)論上講,為了減少(shao)機械密封(feng)的(de)磨損量,應該(gai)在合理(li)的(de)動力流體潤(run)滑條件下工作運轉(zhuan)...
我們(men)使(shi)用泵過程(cheng)(cheng)中總會遇(yu)到密封膠圈損壞的情況(kuang),一旦損壞就要(yao)進行更換,作(zuo)為一個工程(cheng)(cheng)技術(shu)人員首(shou)先要(yao)分辨自(zi)己的泵到底是(shi)哪種型號(hao),才能購買到相(xiang)應口徑的機械密封,由(you)于在市場...
在使用(yong)過程中,大多(duo)數機(ji)械密(mi)(mi)封都屬于(yu)接(jie)(jie)觸(chu)式密(mi)(mi)封,其(qi)機(ji)理是靠動(dong)密(mi)(mi)封環與(yu)靜(jing)密(mi)(mi)封環的接(jie)(jie)觸(chu)端面在密(mi)(mi)封流體壓(ya)力和(he)彈(dan)性元件壓(ya)緊力的作(zuo)用(yong)下緊密(mi)(mi)貼合(he),并相對滑動(dong)而(er)達到密(mi)(mi)封。工作(zuo)時...
