立式管道(dào)離心泵的安裝技術(shù)關鍵在于确定離心泵安(ān)裝高度即(jí)吸程。這個高度是指水源(yuán)水面到 立式(shì)管道離(lí)心泵 葉輪中心線的(de)垂直(zhí)距離，它與允許吸上真(zhēn)空高度不能(néng)混爲一談，水泵産品說明書或銘牌上标示的允許(xǔ)吸上真空(kōng)高度是指水泵進水口斷面上的真空值，而且是在1标(biāo)準大氣壓(yā)下、水溫20℃情況下，進行試(shì)驗而測(cè)定得的。它并沒有(yǒu)考慮(lǜ)吸水管道配套以後的水(shuǐ)流狀況。而水泵安裝高(gāo)度應該是允許吸(xī)上(shàng)真(zhēn)空高度扣除了(le)吸水管道損失揚程以後，所剩下的那部分數值(zhí)，它要克(kè)服實際地形吸水高度。水泵安裝高(gāo)度不能超過計算值，否則，離心(xīn)泵将會抽不上水來。另(lìng)外，影響計算值的大小是(shì)吸水管道的(de)阻力損失(shī)揚程(chéng)，因此，宜采用短(duǎn)的管路布置，并盡量(liàng)少裝彎頭等配件，也可考慮适當配大一些口徑的 立式管道離心泵 水(shuǐ)管，以減管内流速(圖\文 xiaojikuaipao.top/ )。

Vertical pipeline centrifugal pump installation technology is the key to determine the suction centrifugal pump installation height. This highly refers to the water surface to the vertical pipeline centrifugal pump impeller centerline vertical distance, and it allows suction vacuum height can not be confused, pump product brochures or nameplate marking allows suction vacuum height refers to the value of the vacuum on the water inlet of the water pump section, and in1 standard atmospheric pressure, water temperature 20℃condition next, the test and measurement. It does not take into account the suction pipe supporting later flow condition. And the pump mounting height should be allowed to deduct the suction vacuum suction piping loss of lift, the remaining portion of numerical value, it is to overcome the real terrain suction height. Pump mounting height should not exceed the calculated value, otherwise, centrifugal pump will be pumped to not Sheung shui. In addition, affect the calculation value is the size of the suction piping resistance loss of lift, therefore, should adopt the most short circuit arrangement, and minimize the loaded elbow parts, may also be considered appropriate with a larger caliber vertical pipeline centrifugal pump water pipe, to reduce the flow velocity in the tube.
