機(jī)械密封常見(jiàn)4個(gè)泄漏點(diǎn)
泄漏點(diǎn)1—壓蓋與腔體間的密封圈,靜密封點(diǎn),密封圈與相配合件之間相對(duì)靜止.
泄漏點(diǎn)2—非補(bǔ)償環(huán)密封圈,靜密封點(diǎn),密封圈與相配合件之間相對(duì)靜止;
泄漏點(diǎn)3—補(bǔ)償環(huán)密封圈,靜密封點(diǎn),密封圈與軸或軸套之間有微動(dòng);
泄漏點(diǎn)4—摩擦端面泄漏點(diǎn),依靠彈力和介質(zhì)壓力保持貼和(動(dòng)密封點(diǎn),兩個(gè)摩擦副之間有相對(duì)轉(zhuǎn)動(dòng))
