無介質或輸送介(jiè)質流量小：使轉子主(zhǔ)軸與穩定軸承幹摩，燒碎軸承。 磁力泵 是(shì)由輸送(sòng)介質給滑動軸承提供(gòng)潤滑和冷卻的，在沒有開入口閥或出口閥的(de)情況下(xià)，滑動(dòng)軸承因無輸送介質潤滑和冷卻而導緻高溫從而損壞。
隔離套(tào)損壞：磁力泵的磁力(lì)聯軸器是由泵所(suǒ)輸送介質冷(lěng)卻的，如果介質中有硬質顆粒，很容易造成隔離套劃(huà)傷或劃穿，有時如果維護方法不當也有可能造(zào)成隔離套(tào)的損壞。
磁力泵因氣蝕而導緻的問(wèn)題：泵産生氣蝕的原因主要有泵入(rù)口管阻大、輸送介(jiè)質氣相較(jiào)多、灌泵(bèng)不充(chōng)分、泵入口能頭(tóu)不夠等原因。氣(qì)蝕對泵的危害大(dà)，發生(shēng)氣蝕時泵劇烈振動，平衡嚴重破壞，将導緻泵軸(zhóu)承、轉子或葉輪損壞。這是 磁(cí)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.
