怎樣防止磁力泵使用壽命短
防止退磁磁力矩不可設計得過小。應在規定溫度條件下運行，嚴禁介質溫度超標。可在磁力泵隔離套外表面裝設鉑電阻溫度傳感器檢測環隙區域的溫升，以便溫度超限時報警或停機。防止顆粒進入不允許有鐵磁雜質、顆粒進入磁力傳動器和軸承摩擦副。輸送易結晶或沉淀的介質后要及時沖洗，以保障滑動軸承的使用壽命。輸送含有固體顆粒的介質時，應在泵流管入口處過濾。防止干摩擦 嚴禁空轉。嚴禁介質抽空。在出口閥關閉的情況下，泵連續運轉時間不得超過2min，以防磁力傳動器過熱而失效。不可用在有壓力的系統中由于磁力泵泵腔中存在一定的間系及磁力泵內使用的是“靜軸承”，由此該系列泵絕不可以使用在有壓力的系統中，正壓與負壓均不可行(圖\文www.ingvk.cn/)。

Prevent demagnetization magnetic moment can not be designed too small. Should be in the specified temperature conditions, forbidden exceed the standard medium temperature. In the insulation shell of magnet pump outer surface provided with platinum resistance temperature sensor detection annulus area temperature, so that the temperature exceeds the limit alarm or shutdown. To prevent the particles into the ferromagnetic impurities are not allowed, the particles into the magnetic actuators and bearing friction pair. Conveying crystallizable or precipitation of the medium to the flushing, in order to ensure the service life of the sliding bearing. The transport of solid particles of the medium, should be in the pump flow tube inlet filter. Prevention of dry friction no idling. No medium. The outlet valve is closed, the pump running time should not exceed2min, to prevent overheating and failure of magnetic driver. Not available in the pressure of the system due to the magnetic force pump exist in between the Department and in the magnetic pump is using the" bearing", this series pump must not be used in pressure system, a positive pressure and a negative pressure are not feasible.
