適用于工業(yè)和城市給排水、高層建筑增壓供水,園林噴灌、消防增壓、遠距離送水、采暖、浴室等冷暖水循環(huán)增壓及設(shè)備配套等,尤其適用于小型鍋爐給水。
D型水泵為多級分段式,其吸入口位于進水段上,成水平方向,吐出口在出水段上垂直向上,其揚程可根據(jù)使用需要而增減水泵級數(shù)。水泵裝配良好與否,對性能影響關(guān)系很大,尤其是各個葉輪的口出與導(dǎo)翼的進出中心,其中稍有偏差即將使水泵的流量減少,揚程降低效率差,故在檢修后裝配時務(wù)必注意。 D型水泵的主要零件有:進水段、中段、出水段、葉輪、導(dǎo)翼擋板、出水段導(dǎo)翼、軸、密封環(huán)、平衝盤、軸套、尾蓋及軸承體。 進水段、中段、導(dǎo)葉擋板、出水段導(dǎo)翼、出水段及尾蓋均為銹鐵制成,共同形成泵的工作室。 葉輪為優(yōu)質(zhì)銹鐵制成,內(nèi)有葉片,液體沿軸向單側(cè)進入,由于葉輪前后受壓不等,必然存在軸向力,此軸向力由平衝盤來承擔(dān),葉輪制造時經(jīng)靜平衡試驗。 軸為優(yōu)質(zhì)炭素鋼制成,中間裝有葉輪,用鍵、軸套及軸套螺母固定在軸上。軸的一端裝聯(lián)軸器部件,與電 機直接連接。 密封環(huán)為銹鐵制成,防止水泵高壓水漏回進水部分,分別固定在進水段與中段之上,為易損件,磨損后可用備件更換。 平衡環(huán)為鑄鐵制成,固定在出水段上,它與平衡盤共同組成平衝裝置。 平衡盤為耐磨銹鐵制成,裝在軸上,位于出水段與尾蓋之間,平衡軸向力。 軸套為銹鐵制成,位于填料室處,作固定葉輪和保護泵軸入用,為易損件,磨損后可用備件更換。 軸承是單列向心球軸承,采用鈣基潤滑脂潤滑。填料起密封作用,防止空氣進入和大量液體漏出,填料密封由進水段和尾蓋上的填料室,填料壓蓋,填料環(huán)及填料等組成,少量高壓水流入填料室中起水封作用。填料的松緊程度必須適當(dāng),不可太緊亦不可太松,以液體能一滴一滴的滲出為準(zhǔn)。如果填料太緊,軸套容易發(fā)熱,同時耗費功率。填料太松,由于液體流失要降低水泵的效率。
