可以是同心接管。管路附件的選配管路附件的選配應(yīng)貫徹既安全又經(jīng)濟(jì)的原則。也就是說，既能保證機(jī)組的正常運(yùn)行，又要選配最簡單的管路附件。以減少揚(yáng)程損失。如濾網(wǎng)，在水源清潔無雜物的情況下，可不設(shè)置。底閥，在用真空能夠抽氣充水或用其它方法充水時(shí)，也可不用。出水管路上如能用拍門代替逆止閥，就盡量用拍門。除離心泵和混流泵采用閘閥外，進(jìn)水管路和軸流泵出水管路都不應(yīng)安裝閘閥。此外進(jìn)、出水管路都要盡量減少彎管。對(duì)一個(gè)排灌站來說，究竟應(yīng)設(shè)置哪些管路附件，應(yīng)根據(jù)具體情況選配。有一句老話叫做“只有合腳的鞋才是好鞋”，而對(duì)于臥式混流泵來說也是如此，只有選擇合適的水泵才能更好的使用，合適的水泵才是我們所需要的水泵。所以如果我們需要選購臥式混流泵時(shí)要多加注意。
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)簡單，使用可靠，裝修方便，而且效率高，體型小，重量輕。jdhuiquan4.20
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)

低速用DA表示，用于鍋爐給水的多級(jí)離心泵，用DG表示。自吸離心泵自吸泵是靠泵自身的特殊結(jié)構(gòu)而產(chǎn)生自吸作用的單級(jí)單吸離心泵，稱為自吸離心泵。和普通離心泵相比，在泵體結(jié)構(gòu)上有顯著差別：一是泵進(jìn)口位置提高，有時(shí)還裝上閥；二是在出水側(cè)設(shè)置了一個(gè)氣水分離室。泵外自吸泵，是在泵外加有自吸裝置，如帶有旋渦泵、水環(huán)真空泵、射流泵以及手動(dòng)泵等。自吸泵與普通離心泵相比，具有結(jié)構(gòu)緊湊、使用操作簡單，不但省去了起動(dòng)前灌大量引水的麻煩，也省去了進(jìn)水管低閥。減少了進(jìn)水阻力，增加泵的出水量，但與同規(guī)格的普通離心泵的效率相比要低3%～5%。自吸泵較多的是應(yīng)用在輕小型噴灌機(jī)組和管道灌機(jī)組上。自吸離心泵品種規(guī)格較多，有ZX型、TC型、BPZ型和ZB型等。

The materials for the Water Guide pipe, the pump body and the pump cover are cast iron. There are infiltrating grooves on the inner surface of the rubber guide bearing near the wheel, and the guide bearing is mounted directly in the housing of the pump body, which can be replaced on site after wear. The rolling bearings contained in the pump cover are two single-row phase ball bearings. The main factory producing guanting is Fujian Youxi guanting factory. (Ix) Manual pumping of labor-driven piston pumps, diaphragm pumps and screw pumps and other water extrb tools, collectively referred to as manual pumps. Manual pumps are divided into shallow well dynamic pumps and deep wells manual pumps. The flow rate of shallow well piston pump is 0.34~4.214 cubic meter/time, adapt to the suction process 2~7 meters. The flow rate of the deep well piston pump is 0.056~0.601 cubic meters/When the head is 15~40 m. The flow rate of the diaphragm pump is 0.8~6.01 cubic meters/when the flow rate of the screw pump is 0.056~0.671 cubic meter/time. (10) The pump shell of the pump is generally cast iron, it is easy to crack under the b of mechanical force or thermal stress.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.
