1．無(wú)介質或輸(shū)送介(jiè)質流量小：使轉(zhuǎn)子主軸與(yǔ)穩定(dìng)軸承(chéng)幹(gàn)摩，燒碎軸承。 磁力(lì)泵 是由(yóu)輸送介質給(gěi)滑動(dòng)軸承提供潤滑和冷卻的(de)，在沒有(yǒu)開(kāi)入口閥或出口閥的情況下，滑動軸(zhóu)承因無輸送介質潤滑和冷卻(què)而導(dǎo)緻高溫從(cóng)而損壞(huài)。
2．磁(cí)力泵因氣蝕(shí)而導緻(zhì)的問題：泵産(chǎn)生(shēng)氣蝕的(de)原(yuán)因主(zhǔ)要有泵入(rù)口管阻大、輸送介質(zhì)氣相較多、灌泵(bèng)不充(chōng)分(fèn)、泵(bèng)入口(kǒu)能頭不夠(gòu)等原(yuán)因。氣蝕(shí)對泵的(de)危害大，發生氣(qì)蝕時泵(bèng)劇(jù)烈振(zhèn)動，平衡嚴重破壞，将導緻泵軸(zhóu)承、轉(zhuǎn)子或(huò)葉輪(lún)損壞(huài)。這是(shì)磁力泵故障發(fā)生的(de)常見(jiàn)原因。
3．隔離(lí)套損壞：磁力泵(bèng)的磁力聯軸器(qì)是由泵所輸送介(jiè)質冷(lěng)卻的，如(rú)果介質(zhì)中有硬(yìng)質顆粒，很容易造成隔離套劃(huà)傷或劃穿，有時(shí)如果維護方法(fǎ)不當也有可能(néng)造成隔離(lí)套的損壞(huài)。
磁(cí)力(lì)泵的種類　目前國内(nèi)廠(chǎng)家的磁力泵(bèng)大緻可分爲：不鏽鋼磁(cí)力(lì)泵、工(gōng)程塑料磁力泵、氟塑料磁(cí)力泵(bèng)、耐高溫磁力泵(bèng)、多級 磁(cí)力泵 等(děng)幾大類(lèi)(圖(tú)\文 xiaojikuaipao.top/index.asp )。
中(zhōng)譯英(yīng)：
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.
