                  淺析CQB氟塑料磁力泵運行前后的注意事項

                     淺析CQB氟塑料磁力泵運行前后的注意事項
                    CQB氟塑料磁力泵機械密封的正常運行和維護很重要,關系到工業生產加工的效率以及成本。所以大家要了解氟塑料磁力泵在運行前后的注意事項。
                    1、發動前的準備工作及注意事項
                    全部查看機械密封,以及附屬設備和管線裝置是不是*,是不是契合技術需求。機械密封發動前進行靜壓實驗,查看機械密封是不是有走漏表象。若走漏較多,應查清原因設法消除。如仍無效,則應拆開查看并重新裝置。通常靜壓實驗壓力用2~3公斤/平方厘米。按旋向盤車,查看是不是輕快均勻。如盤車費勁或不動時,則應查看裝配尺寸是不是錯誤,裝置是不是合理。
                    2、CQB氟塑料磁力泵安裝與停運
                    發動前應堅持密封腔內充滿液體。對于輸送凝結的介質時,應用蒸氣將密封腔加熱使介質熔化。發動前必須盤車,以防止突然發動而形成軟環碎裂。對于利用泵外封油體系的機械密封,應先發動封油體系。停車后終中止封油體系。熱油泵停運后不能馬上中止封油腔及端面密封的冷卻水,應待端面密封處油溫降到80度以下時,才可以中止冷卻水,避免損壞密封零件。
                    3、運行
                    CQB氟塑料磁力泵發動后若有輕微泄漏現象,應調查一段時間。如連續運轉4小時,泄漏量仍不減小,則應停泵查看。氟塑料磁力泵的操作壓力應平穩,壓力波動不大于1公斤/平方厘米。泵在工作中,應避免發生抽空現象,避免形成。
