產(chǎn)品用途
LG-B型立式多級(jí)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(shè)備配套用泵;也適用于化工流程冷卻塔的自動(dòng)補(bǔ)水;系統(tǒng)穩(wěn)壓、生產(chǎn)工藝循環(huán)用水、遠(yuǎn)距離輸送、鍋爐給水等給水設(shè)備之用。
產(chǎn)品特點(diǎn)
1、泵結(jié)構(gòu)緊湊、體積小、外形美觀,其結(jié)構(gòu)決定安裝占地面積小,如加上防護(hù)罩可置于戶外使用。 2、葉輪直接安裝在電機(jī)軸上,從而保證泵的同心度,因而增強(qiáng)了泵的運(yùn)行穩(wěn)定性和延長(zhǎng)泵的使用壽命。 3、軸封采用機(jī)械密封或機(jī)械密封的組合,采用優(yōu)質(zhì)的質(zhì)合金密封環(huán),增強(qiáng)了密封的耐磨性能有效地延長(zhǎng)壽命。4、安裝檢修方便,無(wú)需拆動(dòng)管路系統(tǒng)。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(jù)流量和揚(yáng)程的需要采用泵的串、并聯(lián)運(yùn)行方式。6、可根據(jù)需要,吸入口和吐出口可安裝成0°、90°、180°、270°幾個(gè)不同方向以滿足不同的連接場(chǎng)合。7、泵揚(yáng)程可根據(jù)需要增減水泵級(jí)數(shù)并結(jié)合切割葉輪外徑予以滿足,而不改變安裝占地面積。
