PBG型屏蔽式管道泵-概述
采用的水力模型,根據(jù)IS型離心泵之性能參數(shù)和立式泵的獨特結構組合設計,并嚴格按照國際ISo2858進行設計制造,該產(chǎn)品軸封選用硬質合金機械密封裝置,具有高效節(jié)能、性能可靠、安裝使用方便等特點。
PBG型屏蔽式管道泵-主要特點
運行平穩(wěn):泵軸的同心度及葉輪優(yōu)異的動靜平衡,保證平穩(wěn)運行,絕無振動。
滴水不漏:不同材質的硬質合金密封,保證了不同介質輸送均無泄漏。
噪音低:兩個低噪音的軸承支撐下的水泵,運轉平穩(wěn),除電機微弱聲響,基本無噪音。
故障率低:結構簡單合理,關鍵部分采用國際品質配套,整機無故障工作時間大大提高。
維修方便:更換密封、軸承、簡易方便。
占地更?。撼隹诳上蜃?、向右、向上三個方向,便管道布置安裝,節(jié)省空間。
PBG型屏蔽式管道泵-產(chǎn)品概述:
PBG型屏蔽式管道泵,吸收了國際上屏蔽泵設計及制造的技術,將電機的屏蔽技術應用于流體輸送領域,為適應國內市場需求而推出的系列化新產(chǎn)品。PBG型屏蔽式管道泵系列性能參數(shù)基本符合國際標準IS02858及國家標準JB/T6878.2-93的規(guī)定。具有設計規(guī)范,通用化程度高,結構合理,性能穩(wěn)定,運轉低噪音,無振動等顯著特點,是替代常規(guī)臥式離心泵,立式管道泵的理想產(chǎn)品。全系列共67個品種,184個規(guī)格,其性能范圍:流量6.3~1080m3/h,揚程12.5~125m,配用電機功率0.37~160kW,轉速1450r/min和2900r/min。
PBG型屏蔽式管道泵-產(chǎn)品特點:
①泵結構緊湊,機泵一體化,體積小。其立式結構具有安裝占地面積小,運行平穩(wěn),安裝無需調整。
②泵進出口設計成規(guī)格相同法蘭,且位于同一中心線上,可象閥門一樣直接安裝在管路上,且中心低,便于管道布置,安裝特別方便。
③泵與電機同軸,軸向尺寸短,使泵運行更加平穩(wěn),噪音低。
④取消傳統(tǒng)軸封方式,避免了輸送介質的外泄,因此具有完全無泄漏的顯著特點。
⑤用滑動軸承替代常規(guī)電機滾動軸承,使泵具有運行特別平穩(wěn),振動噪音極低。
⑥安裝檢修方便,無需拆動管路系統(tǒng),只要拆下連接體螺母即可抽出全部轉子部件進行檢查和維修。
⑦可根據(jù)使用要求即流量和揚程的需要進行泵的串、并聯(lián)運行方式。
PBG型屏蔽式管道泵-主要用途:
①PBG型屏蔽式管道泵普通型供輸送清水及物理化學性質類似于清水的其他液體之用。介質使用溫度不超過80℃,適用于工業(yè)和城市給排水,高層建筑增壓送水、園林噴灌、消防增壓、遠距離輸送、暖通制冷循環(huán)、浴室等冷暖水循環(huán)增壓及設備配套。特別適用對振動、噪音要求較高的場合,如地下泵房、空調制冷系統(tǒng)等。
②PBG型屏蔽式管道泵熱水型主要供輸送溫度不超過160℃不含固體顆粒的軟水之用,適用于能源、冶金、化工、紡織、造紙以及賓館、飯店、浴室、鍋爐熱水增壓循環(huán)輸送及城市采暖系統(tǒng)循環(huán)等場合。
③PBG型屏蔽式管道泵防腐型供輸送不含固體顆粒,具有腐蝕性,粘度類似于水的液體,適用于石油、化工、冶金、電力、造紙、食品、制藥和合成纖維等部門。
