混流泵的安裝原則及注意點(diǎn): 1, 安裝原則: (1),水泵的安裝高度:最高上水位不應(yīng)高于軸承下端,最低下水位取決于泵的允許吸上真空度(應(yīng)減去管路損失)。 (2),水泵應(yīng)盡可能靠近水源,以縮短進(jìn)水管路,減少管路損失。 (3),管路應(yīng)盡量直和短。一般在進(jìn)水口用一只90°或33°彎管,水泵底腳基礎(chǔ)斜澆,可省去出水彎管。
一.概述
1.用途:HW混流泵為臥式,單級(jí),單吸,渦殼式混流泵。適用于輸送清水或物理,化學(xué)性質(zhì)類似于水的其它液體。被輸送液體溫度不宜高于50度。廣泛用于農(nóng)田灌溉,工業(yè)和城市排水等多種場(chǎng)合。HW泵的性能范圍:流量90-9000m3/h 揚(yáng)程3.5-22m。
2. 特點(diǎn):結(jié)構(gòu)簡(jiǎn)單,使用可靠,裝修方便,而且效率高,體型小,重量輕。jdhuiquan5.15
3. 傳動(dòng)方式:用直接傳動(dòng)和變速傳動(dòng)。常用動(dòng)力機(jī)是電動(dòng)機(jī)和柴油機(jī)。訂貨 時(shí)應(yīng)明確動(dòng)力機(jī)的型號(hào),以便確定聯(lián)軸器和皮帶輪的型號(hào)
4.型號(hào)說(shuō)明:以150HW-8S例
150---------泵進(jìn)出口直徑mm
8------------設(shè)計(jì)揚(yáng)程 m
S------------變型代號(hào)

混流泵功率消耗過(guò)大 產(chǎn)生原因:水泵轉(zhuǎn)速太高; 水泵主軸彎曲或水泵主軸與電機(jī)主軸不同心或不平行; 選用水泵揚(yáng)程不合適;水泵吸入泥沙或有堵塞物;電機(jī)滾珠軸承損壞等。 解決辦法:檢查電路電壓,降低水泵轉(zhuǎn)速; 矯正水泵主軸或調(diào)整水泵與電機(jī)的相對(duì)位置; 選用合適揚(yáng)程的水泵;清理泥沙或堵塞物;更換電機(jī)的滾珠軸承。 4。3混流泵泵體劇烈振動(dòng)或產(chǎn)生噪音 產(chǎn)生原因:水泵安裝不牢或水泵安裝過(guò)高; 電機(jī)滾珠軸承損壞;水泵主軸彎曲或與電機(jī)主軸不同心, 不平行等。 解決辦法:裝穩(wěn)水泵或降低水泵的安裝高度; 更換電機(jī)滾珠軸承; 矯正彎曲的水泵主軸或調(diào)整好水泵與電機(jī)的相對(duì)位置。
二.結(jié)構(gòu)和作用
1.HW pump mainly has pump cover, impeller, pump body, pump shaft, bushing, and bearing body and other major components. The pump cover is connected with the pump body and the inlet pipe respectively. 2. There should be an appropriate gap between the pump cover plane and the impeller plane. The gap is too small will produce friction, the gap is too large, will lead to the pump body pressure water a large number of reflux, is the pump efficiency reduction. The suitable gap used in practice is 0.3-0.7mm, and the gap can be adjusted by adding and subtracting the thickness of the paper pad.
3. The shaft is applied to protect the pump shaft and should be replaced in time after wear.
1. Screw holes at the upper end of the pump body, used for filling water diversion or connecting vacuum pump pumping gas to divert water.
2. In order to expand the scope of application of the pump to meet the different needs of users, can cut the outer diameter of the impeller or exchange different perbance of the impeller.
