However, improper installation, long use time or poor maintenance, but also easy to wear or destroy. Rolling bearings In addition to the individual parts can be replaced with new, generally have to replace the whole parts. The mouth ring is also called a leak reduction or grinding ring. It is one of the most wear-prone parts in the pump. After wear can be repaired or replaced with new. When replacing the new leak reduction ring, its inner diameter should be configured according to the outer diameter of the impeller inlet. If the impeller inlet diameter wear, can be turning processing, in order to eliminate trench marks and ellipses, and then configure the internal diameter reduction of the leakage ring, impeller inlet diameter can generally be turning three times. Filler after a long time will harden and lose elasticity, will make the pump leakage, leakage, generally should replace the new filler. Oil seal is rubber products, easy to wear and aging, generally have to replace new parts. Parameters and properties of water pump (1) The main beters of the pump pump beters are the main technical data of the pump's operating perbance, including flow, lift, speed, efficiency and ratio of the number of revolutions. Flow rate (Q) The flow rate of the pump refers to the amount of liquid discharged during the unit time.
一.概述
1.用途：HW混流泵為臥式，單級，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 揚程3.5-22m。
2. 特點：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

水泵轉(zhuǎn)速一定時，流量與揚程、功率、效率的關(guān)系，即其揚程、功率和效率均隨流量變化而按一定規(guī)律變化。以離心泵和軸流泵為例，它們的變化規(guī)律是不相同的。這兩種泵的揚程雖然都隨流量的增大而降低，隨流量的減少而增高，但軸流泵變化更為顯著。而且當(dāng)流量為零時（相當(dāng)于出水管閘閥關(guān)閉），它的揚程比正常值升高很多。而離心泵揚程升高并不顯著。兩種水泵的功率與流量間的關(guān)系，其變化規(guī)律是相反的。離心泵的功率隨流量的減小而降低（或者說隨揚程的增大而降低），當(dāng)離心泵的流量為零時，功率為最小。因此離心泵在起動和停車前應(yīng)關(guān)閉閘閥，以降低起動功率和穩(wěn)定停車。而軸流泵則相反，其功率是隨流量的減小而增高，流量為零時功率最大。因此不能關(guān)閉閘閥起動。

使水沿出水管流出。葉輪不斷的旋轉(zhuǎn)，水也就被連續(xù)壓送到高處。軸流泵的一般特點（1）水在軸流泵的流經(jīng)方向是沿葉輪的軸相、軸相流出，因此稱軸流泵。（2）揚程低（1～13米）、流量大、效益高，適于平原、湖區(qū)、河網(wǎng)區(qū)排灌。（3）起動前不需灌水，操作簡單。（三）混流泵的工作原理及特點混流泵的工作原理由于混流泵的葉輪形狀介于離心泵葉輪和軸流泵葉輪之間，因此，混流泵的工作原理既有離心力又有升力，靠兩者的綜合作用，水則以與軸組成一定角度流出葉輪，通過蝸殼室和管路把水提向高處。混流蹦的一般特點（1）混流泵與離心泵相比，揚程較低，流量較大，與軸流泵相比，揚程較高，流量較低。適用于平原、湖區(qū)排灌。（2）水沿混流泵的流經(jīng)方向與葉輪軸成一定角度而和流出的。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.
