1．無介質或輸(shū)送介(jiè)質流量小：使轉子主軸與(yǔ)穩(wěn)定軸承幹摩，燒碎軸承。 磁(cí)力泵 是由輸送介(jiè)質給滑動軸承提供潤滑和冷卻的，在沒有開入口閥或出(chū)口閥的(de)情況下，滑動軸(zhóu)承因無輸送(sòng)介質潤滑和(hé)冷卻而導緻高溫從而損(sǔn)壞。
2．磁力泵因氣蝕(shí)而導緻的問題：泵産生氣蝕(shí)的原因主要有泵入口管阻大、輸送介質氣(qì)相較多、灌泵不充分、泵入口能頭不夠等原因。氣蝕對泵的(de)危害(hài)大，發(fā)生氣蝕時泵劇烈振(zhèn)動，平衡嚴(yán)重破壞，将導緻泵軸承、轉子或葉輪損壞。這是磁力泵故障發生的常見(jiàn)原因。
3．隔離套損壞：磁力泵的磁力聯軸器是由泵所輸送介質冷卻的，如果介質中有硬質顆粒，很容易造成隔離套劃傷或(huò)劃(huà)穿，有時(shí)如果維護方法(fǎ)不當也有可(kě)能造成隔離套的損壞。
磁力泵的種類　目前國内廠家的磁力泵大緻可分爲：不鏽鋼磁力泵、工程塑料磁力泵、氟塑料磁力泵(bèng)、耐高溫磁力泵(bèng)、多級 磁力泵 等幾大類(圖(tú)\文 xiaojikuaipao.top/index.asp )。

1medium or small flow conveying medium: the rotor spindle bearing and stability of 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.
2magnetic 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.
3 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 types at present domestic manufacturers of magnetic pump can be broadly divided into: stainless steel, engineering plastic magnetic pump magnetic pump, fluorine plastic magnetic pump, resisting high temperature magnetic pump, multistage pump and other categories.
