密封面有切邊:
這是由于密封面分得太開,而在合攏時斷裂。閃蒸(氣化)是較普遍的密封面分開的原因,特別是在熱水系統(tǒng)或流體中有凝液時,水從液體膨脹成蒸氣,可使密封面分開。(冷介質(zhì)氣化也同樣會造成)
密封的金屬零件,如彈簧、固定螺釘,傳動件及金屬套都可能成為密封失效的根源。受交變應(yīng)力作用的彈簧受腐蝕是它的首要問題,因為金屬在應(yīng)力作用下會迅速腐蝕,不繡鋼彈簧易受氯化物的應(yīng)力腐蝕,且世界上存在許多的氯化物,所以有國外部門建議,不要使用不銹鋼彈簧,而*使用耐蝕性較高的哈斯特合金鋼的彈簧。另外,裝配不當(dāng)造成彈簧疲勞是失效的又一原因。
機(jī)械密封使用的固定螺釘,不要用硬化后的材料來做,因熱處理會降低金屬的耐蝕能力,而未經(jīng)熱處理的較軟的固定螺釘能緊固在軸上。
振動、偏斜、不同心會使傳動件磨損,如密封面啟動時有粘住的現(xiàn)象時,傳動件會彎曲甚至損壞,而磨擦作用產(chǎn)生的熱常常加劇腐蝕。
金屬套外圓表面的磨痕,可能是從密封側(cè)進(jìn)入套內(nèi)的固體微粒造成的,它干擾密封的隨動能力。也可能是偏斜,不同心的原因造成的。
金屬在溫升過程中要改變顏色,不銹鋼在使用時應(yīng)注意下列溫度時的顏色。
淡黃色————溫度為700~800℉(約370~432℃)
棕 色————溫度為900~1000℉(約486~540℃)
蘭 色————溫度為1100℉(約590℃)
黑 色————溫度為1200℉(約648℃)
