無(wú)介質或(huò)輸送介(jiè)質流量小(xiǎo)：使轉子主(zhǔ)軸(zhóu)與(yǔ)穩定(dìng)軸承幹摩(mó)，燒碎軸承(chéng)。 磁(cí)力泵 是(shì)由輸送介(jiè)質給(gěi)滑動軸承提供(gòng)潤滑(huá)和冷(lěng)卻的，在沒(méi)有開入口閥或出(chū)口閥的(de)情況(kuàng)下，滑動軸(zhóu)承因無輸(shū)送介(jiè)質潤滑和冷卻(què)而導(dǎo)緻(zhì)高溫從而損壞。
隔離套(tào)損壞(huài)：磁力(lì)泵的(de)磁力聯軸器是(shì)由泵(bèng)所輸(shū)送介質冷(lěng)卻(què)的，如果(guǒ)介質(zhì)中(zhōng)有(yǒu)硬質(zhì)顆粒，很(hěn)容(róng)易造(zào)成隔離套劃傷(shāng)或劃穿，有時如果維護方(fāng)法不當也有可能造(zào)成隔離套的損(sǔn)壞。
磁力(lì)泵因氣(qì)蝕而導緻的問題：泵(bèng)産生氣蝕(shí)的原因(yīn)主(zhǔ)要有(yǒu)泵入(rù)口管阻大(dà)、輸送介質氣相(xiàng)較多、灌泵(bèng)不充(chōng)分、泵入口能頭(tóu)不夠等原因。氣(qì)蝕對(duì)泵(bèng)的危害大，發(fā)生(shēng)氣(qì)蝕時(shí)泵劇烈(liè)振動，平衡嚴重破壞，将(jiāng)導緻泵軸(zhóu)承、轉(zhuǎn)子或葉(yè)輪(lún)損(sǔn)壞(huài)。這是 磁力泵 故障發生的常見(jiàn)原因(圖\文 xiaojikuaipao.top/ )。
中譯英：
no media or transmission medium flow so that the rotor spindle and bearings: stable dry friction, burning up the bearing. magnetic pump is determined by the conveying medium for sliding bearing for lubrication and cooling, in the absence of open entrance valve or outlet valve, sliding bearing for lubrication and cooling conveying medium to high temperature and damage.
the isolation sleeve damage: magnetic pump magnetic coupling is pumped by the transmission medium cooling, if in the medium of hard particles, is very easy to cause the isolation sleeve scratch or cut through, sometimes if maintenance methods also have the potential to cause the isolation sleeve damage.
magnetic pump due to cavitation which leads to the question: pump cavitation main pump entrance pipe resistance big, medium gas phase more, irrigation pump, pump entrance can not fully head is insufficient wait for a reason. the pump cavitation damage, cavitation occurs when the pump vibration, balance seriously damaged, will cause the pump bearing, rotor or impeller damage. this is a common cause of magnetic pump fault.
