磁(cí)力泵(bèng)常見(jiàn)問題解析(xī)

無介質(zhì)或輸送(sòng)介質(zhì)流量(liàng)小：使(shǐ)轉(zhuǎn)子(zǐ)主(zhǔ)軸與穩(wěn)定軸(zhóu)承幹摩，燒碎軸(zhóu)承。 磁力泵 是由輸送介質(zhì)給滑動(dòng)軸承提(tí)供(gòng)潤滑(huá)和(hé)冷卻的，在(zài)沒有開入(rù)口閥或出口閥(fá)的情況下(xià)，滑動軸承因無(wú)輸送介(jiè)質潤滑(huá)和冷(lěng)卻而導緻高溫從而(ér)損(sǔn)壞(huài)。
隔離(lí)套損壞(huài)：磁(cí)力泵的磁力(lì)聯軸器(qì)是由(yóu)泵(bèng)所(suǒ)輸送(sòng)介質冷卻(què)的，如(rú)果介質(zhì)中(zhōng)有硬(yìng)質顆粒，很容易造成(chéng)隔離(lí)套劃(huà)傷或(huò)劃穿，有時(shí)如果(guǒ)維護(hù)方法不當(dāng)也(yě)有(yǒu)可能(néng)造成隔(gé)離(lí)套的(de)損壞(huài)。
磁力泵因(yīn)氣蝕而導緻的問題(tí)：泵産(chǎn)生氣(qì)蝕的原因(yīn)主要(yào)有泵(bèng)入口(kǒu)管阻(zǔ)大、輸送介(jiè)質氣(qì)相較多、灌泵不(bú)充分、泵入口能頭不夠等(děng)原因。氣蝕對泵的危害大(dà)，發(fā)生氣蝕(shí)時泵(bèng)劇烈振動(dòng)，平衡嚴重(zhòng)破壞(huài)，将導(dǎo)緻泵軸承、轉子或葉輪損(sǔn)壞。這(zhè)是 磁力泵(bèng) 故障(zhàng)發(fā)生的常(cháng)見原因(yīn)(圖(tú)\文 xiaojikuaipao.top/ )。
中(zhōng)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.
