射洪機械密封的這三個功能一定要了解
機(ji)械密(mi)(mi)封(feng)包(bao)括壓力(li)控制、溫度(du)控制、流(liu)體替換(堵塞)和雜質去除系(xi)統。在機(ji)械密(mi)(mi)封(feng)系(xi)統中，上(shang)述系(xi)統并不(bu)同時(shi)包(bao)括在內。密(mi)(mi)封(feng)系(xi)統的選擇主要取決于主密(mi)(mi)封(feng)件的應用范圍。例如，如...

雙(shuang)端面小彈簧平衡型密封所用摩擦(ca)副材料(liao)由動環(huan)(huan)和靜環(huan)(huan)所組成的(de)摩擦(ca)副是機(ji)械密封重(zhong)要的(de)零(ling)件(jian)，從理論上講，為了減少機(ji)械密封的(de)磨損量，應該(gai)在合(he)理的(de)動力流體潤滑條件(jian)下工(gong)作運轉...
我(wo)們使(shi)用泵過程中總會(hui)遇到密(mi)封膠圈損壞(huai)的(de)情況，一旦(dan)損壞(huai)就(jiu)要(yao)進行(xing)更換，作為一個工程技術人(ren)員(yuan)首先要(yao)分(fen)辨自己的(de)泵到底是哪種型號(hao)，才能購(gou)買到相應(ying)口徑(jing)的(de)機械密(mi)封，由(you)于在市場...
在使用(yong)過程(cheng)中，大多(duo)數(shu)機(ji)械密(mi)(mi)(mi)封(feng)都(dou)屬于接觸(chu)式(shi)密(mi)(mi)(mi)封(feng)，其(qi)機(ji)理(li)是靠動密(mi)(mi)(mi)封(feng)環與靜密(mi)(mi)(mi)封(feng)環的接觸(chu)端(duan)面在密(mi)(mi)(mi)封(feng)流體(ti)壓力和(he)彈性元(yuan)件(jian)壓緊(jin)力的作用(yong)下緊(jin)密(mi)(mi)(mi)貼(tie)合，并相對(dui)滑動而達到密(mi)(mi)(mi)封(feng)。工(gong)作時(shi)...
