一、產(chǎn)品概述:
GDLB型立式防爆多級管道泵,是永嘉縣良邦泵閥有限公司根據(jù)ISG型立式離心泵及DL型立式多級離心泵的優(yōu)點而設計的。在結(jié)構(gòu)上采用了立式、分段形式,泵的吸入口與排出口設計在下方成一字形,防爆管道泵并采用了*水力模型。泵的軸向力采用水力平衡方法解決,殘余軸向力由一個球軸承承受,因而運轉(zhuǎn)平穩(wěn)、低噪音、占地面積小、裝修方便。外筒體用不銹鋼制造,外型美觀,特別適合于高層建筑多臺泵并聯(lián)使用,以減少單泵機組配帶功率,簡化電控設備。適用于高低層建筑的住宅、醫(yī)院、旅館、百貨大樓、辦公大樓等的消防、生活供水以及空調(diào)機組循環(huán)、冷卻水輸送等。

防爆管道泵為什么要在出口閥門關閉的情況下啟動,并用出口閥門調(diào)節(jié)流量?
如果打開出口閥門的情況下啟動(泵里滿水,出口敞開),離心泵電動機電流會過大容易燒。防爆管道泵這類葉片式泵都怕出口無阻力敞口流,這時候功率輸出zui大,因此調(diào)節(jié)流量用出口閥門調(diào)節(jié)。
而另一類容積泵則相反,如柱塞泵、計量泵,關閉出口閥門開泵會導致閥門與泵之一損壞,因而調(diào)節(jié)流量用將出口部分流量回流到入口或調(diào)節(jié)柱塞行程的方式進行。
