產(chǎn)品概述：
GDL型立式多級管道離心泵是我公司借鑒國外優(yōu)秀泵型并結(jié)合用戶的使用要求，根據(jù)JB/TQ6435-92標準設(shè)計制造的新一代產(chǎn)品。產(chǎn)品全部采用計算機設(shè)計和優(yōu)化處理，20年中經(jīng)過不斷的改進和優(yōu)化，目前已是該泵的第六代改款。該泵吸入、排出口位于同一直線上，可像閥門一樣直接安裝于管路中，使用非常方便。轉(zhuǎn)子部件由軸、葉輪、葉輪擋套、軸套等零件組成，進水段、中段、出水段用拉緊螺栓聯(lián)結(jié)。軸封采用機械密封，用平衡室的壓力水進行潤滑和冷卻。廣泛應(yīng)用于高壓運行系統(tǒng)中冷熱清水的循環(huán)和增壓、高層建筑多臺泵并聯(lián)供水、消防、鍋爐給水和冷卻水系統(tǒng)及各種沖洗液的輸送等。可生產(chǎn)鑄鐵和不銹鋼兩種材質(zhì)。不銹鋼材質(zhì)的型號為GDLF。近年來，因CDL（QDL）系列泵的出現(xiàn)和廣泛應(yīng)用，該泵的使用面漸窄，但其仍有不可替代的作用。
產(chǎn)品特點：
1、管道式，安裝較為方便。
2、揚程范圍比單級泵大。
3、泵體圓筒為不銹鋼材質(zhì)，外形美觀。
4、軸封為機械密封，用戶使用得當?shù)脑?，使用壽命長，而且沒有填料密封滲漏的煩惱。
5、流道經(jīng)過重新設(shè)計，運行的水力噪音不大。
6、立式結(jié)構(gòu)，占地面積小。
