After pumping fluid stop elements and treatment bs are as follows: 1, pipeline leakage. Treatment b: Check the side pipe pipe connection and packing letter sealing status. The side gas is not drained at the time of filling the pump. Treatment: request to pump from the beginning. The side of Russia is blocked by foreign bodies. Treatment b: Stop the pump to deal with foreign bodies. A lot of gas. Treatment: To see if the suction import has a vortex, engulfing depth is not too shallow. The lack of flow factors and treatment bs are as follows. Same as 2, treatment: the adoption of the corresponding measures. System static lift added. Treatment: View liquid height and system pressure. Drag loss added. Treatment: Look at the pipeline and anti-reverse valve and other obstacles. Shell and impeller wear-resistant ring wear too much. Treatment: Replace or repair wear-resistant rings and impellers. Other parts of the leak. Treatment: Look at the shaft seal and other parts. Pump impeller blockage, wear, corrosion. Treatment: Clean, view, Exchange. The head does not have the elements and the treatment b is as follows: 1, the same two 1, three 1, four 6.
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。jdhuiquan4.9
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)

Pumps According to the type can be divided into: cleaning pumps, sewage pumps, chemical pumps. Cleaning pumps are commonly used in centrifugal pumps, multistage pumps, submersible pumps. Sewage pump can be divided into diving type, self-suction type and so on, the so-called chemical pump, is the medium is strong acid strong alkali or corrosive, and so on. The above is a simple classification of pumps. According to the above classification, we next detailed debion of the pump selection Method! The first step: to find out the properties of the medium, if it is water, then use the cleaning pump, but also consider whether the pump is placed in the liquid operation, if it is placed in the liquid inside the operation, then we choose the submersible cleaning pump. If the medium is sewage, then we choose the sewage pump, but also consider whether the pump is operating in the medium. If it is smoked, strong acid then we choose chemical pumps, such as: diaphragm pump, screw pump, FRP pump and so on. Step two: Find out the flow of the pump we need (how much water to hit in one hours), the head (that is, how much water needs to be hit).
二.結(jié)構(gòu)和作用
1.HW型泵主要有泵蓋，葉輪，泵體，泵軸，軸套，及軸承體等主要零件組成。 泵蓋分別與泵體和進(jìn)水管相接。2.泵蓋平面與葉輪平面之間應(yīng)有適當(dāng)間隙。間隙過(guò)小會(huì)產(chǎn)生摩擦，間隙過(guò)大，會(huì)導(dǎo)致泵體內(nèi)的壓力水大量回流，是泵的效率降低。實(shí)際使用的適宜間隙為0.3-0.7mm，間隙可用增減紙墊厚度來(lái)調(diào)整。
3.軸套用以保護(hù)泵軸，磨損后應(yīng)及時(shí)更換。
1.泵體上端的螺孔，用于加灌引水或連接真空泵抽氣引水。
2.為擴(kuò)大泵的適用范圍，滿足用戶不同需求，可切割葉輪外徑或換用不同性能的葉輪。
