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(lèi)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。jdhuiquan6.22
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

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.

當(dāng)混流泵葉輪在水中旋轉(zhuǎn)時(shí)，葉片對(duì)誰(shuí)既產(chǎn)生離心力作用，又具有升力作用，葉輪轉(zhuǎn)動(dòng)時(shí)靠這兩種里的混合作用，所以稱(chēng)為混流泵。當(dāng)原動(dòng)機(jī)帶動(dòng)葉輪旋轉(zhuǎn)后，對(duì)液體的作用既有離心力又有軸向推力，是離心泵和軸流泵的綜合，液體斜向流出葉輪。因此它是介于離心泵和軸流泵之間的一種泵?；炝鞅玫谋绒D(zhuǎn)速高于離心泵，低于軸流泵，一般在300-500之間。它的揚(yáng)程比軸流泵高。
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.
