產(chǎn)品用途
LG-B型立式多級離心泵特別適用于住宅、賓館、辦公大樓等高層建筑恒壓供水、消防、噴淋給水設備配套用泵;也適用于化工流程冷卻塔的自動(dòng)補水;系統穩壓、生產(chǎn)工藝循環(huán)用水、遠距離輸送、鍋爐給水等給水設備之用。
產(chǎn)品特點(diǎn)
1、泵結構緊湊、體積小、外形美觀(guān),其結構決定安裝占地面積小,如加上防護罩可置于戶(hù)外使用。 2、葉輪直接安裝在電機軸上,從而保證泵的同心度,因而增強了泵的運行穩定性和延長(cháng)泵的使用壽命。 3、軸封采用機械密封或機械密封的組合,采用優(yōu)質(zhì)的質(zhì)合金密封環(huán),增強了密封的耐磨性能有效地延長(cháng)壽命。4、安裝檢修方便,無(wú)需拆動(dòng)管路系統。泵進(jìn)口和出口為相同口徑,簡(jiǎn)化了管路的連接。5、可根據流量和揚程的需要采用泵的串、并聯(lián)運行方式。6、可根據需要,吸入口和吐出口可安裝成0°、90°、180°、270°幾個(gè)不同方向以滿(mǎn)足不同的連接場(chǎng)合。7、泵揚程可根據需要增減水泵級數并結合切割葉輪外徑予以滿(mǎn)足,而不改變安裝占地面積。
