臺(tái)灣Northman北部精機(jī)順序閥SCV-G10-1-20

排除方法：更換O形密封圈，上緊接頭處螺栓或螺母一般情況下外球面軸承在運(yùn)轉(zhuǎn)中要注意以下三大事項(xiàng)。第檢查運(yùn)行中機(jī)器的狀況，進(jìn)行監(jiān)測(cè)，以免造成設(shè)備停機(jī)。第如果SKF進(jìn)口軸承潤(rùn)滑不足或過(guò)分潤(rùn)滑,潤(rùn)滑劑內(nèi)含有雜志,負(fù)載過(guò)大,外球面軸承損壞,間隙不足,及油封產(chǎn)生的高溫摩擦等等。高溫經(jīng)常表示軸承已處于異常情況.高溫也有害于在軸承內(nèi)的潤(rùn)滑劑。有時(shí)軸承過(guò)熱可歸咎于軸承的潤(rùn)滑劑.若軸承在超過(guò)125攝氏度的溫度長(zhǎng)期運(yùn)轉(zhuǎn),會(huì)降低軸承壽命。第在打開(kāi)軸承箱時(shí),檢查SKF進(jìn)口軸承并且定期性檢查油封。主軸承溫度過(guò)高，產(chǎn)生點(diǎn)蝕或熔化現(xiàn)象，可能由以下原因之一造成：1）潤(rùn)滑油中斷或油量不足若發(fā)現(xiàn)斷油時(shí)，應(yīng)立即停止給料給水，打開(kāi)軸承上觀察孔蓋，用手試探著（注意防止把手燙傷）接近中空軸頸，檢查軸承溫度。如果軸承尚未過(guò)熱，可停車(chē)處理油路故障；如果軸承溫度已相當(dāng)高，手靠近中空軸勁感到烘燙、冒煙時(shí)，切忌停車(chē)，要從軸承上用人工澆油冷卻，直至軸承溫度恢復(fù)正常后才能停車(chē)。如果未采取降溫措施就停車(chē)，不但不能避免軸承燒毀，而且將發(fā)生中空軸與大瓦抱死的嚴(yán)重事故。潤(rùn)滑油過(guò)稠或過(guò)稀消除辦法:可重新選潤(rùn)滑油型號(hào)；停止使用冷卻水或用電阻加熱。油變質(zhì)應(yīng)清洗軸承及過(guò)油部位，更換潤(rùn)滑油。大瓦研刮的不符合要求應(yīng)重新研刮大瓦，使其符合技術(shù)要求。落入礦砂、鐵屑等雜物，傷害軸承表面，使其表面產(chǎn)生斑痕、拉槽消除辦法：清洗軸承，修理軸承和軸頸。若熔化面積大，則用焊槍熔軸承或重新澆鑄巴氏合金；更換潤(rùn)滑油。潤(rùn)滑油中帶水水能阻止油膜形成，在沒(méi)有油膜的局部點(diǎn)上會(huì)產(chǎn)生裂痕，發(fā)生點(diǎn)蝕。

排除方法：調(diào)整泵與電動(dòng)機(jī)聯(lián)軸器的同心度，使其誤差不超過(guò)0.2mm。一般水泵的銘牌上都提到允許吸上真空高度或必需汽蝕余量NPSHr，就是根據(jù)水泵在額定轉(zhuǎn)速和流量下而又不產(chǎn)生汽蝕為原則，由制造廠試驗(yàn)所確定的吸水高度，為了不發(fā)生汽蝕而限制了水泵葉輪進(jìn)口處的壓力不能低于某一數(shù)值。也就是說(shuō)，水泵葉輪進(jìn)口處的真空度不能高于某一數(shù)值。通常又把水泵葉輪進(jìn)口處允許的壓力，也叫水泵的允許吸上真空度，它與允許吸上真空高度是一回事。蝕的防止措施泵的實(shí)際安裝高度，必須低于或等于水泵的實(shí)際吸水高度。
