And the blockage of leaf rotation, etc., should be solved by corresponding measures. (2) pipe leakage or leakage, may be installed when the bolts are not tightened. If the leakage is not serious, you can apply cement slurry in a leaking or leaking place, tighten the nut with the plate hand, and if the leak is serious, reload it. (3) The pump is violently shaken, may be in the electric rotor imbalance, or the coupling combination is not bad, bearing wear, bending, may also be caused by the rotating parts loosening, rupture and pipe bracket is not tight. Adjustments, reinforcement, straightening or replacement should be made depending on the circumstances. In our daily life or in our work, we often use an industrial machinery, we call it a water pump. Many common pump structures are not very complex, but they may often be uncertain in pump selection, especially when we use the pump for the first time. Let's introduce the pump in the end how to choose not to let us time-consuming and laborious. The first step is to let us know the type of pump.
使用說明
(一)HW型混流泵由泵體、泵蓋、葉輪、泵軸和軸承體等主要零件構(gòu)成。
(二)泵蓋是泵與進(jìn)水管相連的零件,其端面與葉輪之間留有規(guī)定的軸向端面間隙(在消除軸承軸向活 動(dòng)間隙以后,保持規(guī)定的軸向間隙)。間隙過小產(chǎn)生摩擦,過大則會(huì)導(dǎo)致泵內(nèi)壓力水回流,使泵的效率降低,通過增減調(diào)整紙墊達(dá)到規(guī)定的要求的間隙。延伸搜索:水環(huán)真空泵
(三)密封裝置是由填料函、水封函、填料壓蓋和鉛粉(或油浸)石棉盤根組成。其作用有:
1、荼時(shí)防止空氣吸入泵內(nèi),起密封作用。
2、抽水時(shí)防止水從泵內(nèi)過多的沿軸大量流出。
(四)軸套用來保護(hù)軸不使它與填料直接摩擦,若長(zhǎng)期使用中發(fā)現(xiàn)軸套磨損過多,可換軸套。
(五)水泵軸的兩個(gè)支承是軸承體內(nèi)的軸承,軸承體內(nèi)存有適量潤(rùn)滑脂以潤(rùn)滑軸承。
(六)軸上的擋水圈可防止水沿泵流入軸承體內(nèi),從而保護(hù)軸承,延長(zhǎng)使用壽命。
用途/應(yīng)用領(lǐng)域
混流泵混流泵是一種比轉(zhuǎn)速較高的泵型,廣泛應(yīng)用于農(nóng)田灌溉,防澇排洪,污水處理,電站冷卻系統(tǒng)等領(lǐng)域.在大流量,低揚(yáng)程的應(yīng)用場(chǎng)合下,軸流泵揚(yáng)程,流量變化范圍小,區(qū)窄,抗汽蝕性能差,使用混流泵代替軸流泵,能夠在發(fā)揮軸流泵優(yōu)點(diǎn)的基礎(chǔ)上補(bǔ)償這些缺點(diǎn),從而取得更好的使用效果.
高比轉(zhuǎn)速混流泵的設(shè)計(jì)方法
軸面流動(dòng)計(jì)算
采用流線迭代法求解軸面流動(dòng).流線迭代法基于沿任意準(zhǔn)正交線的軸面速度梯度方程和流體運(yùn)動(dòng)的連續(xù)方程,根據(jù)各子流道流量相等的原則,迭代求解沿準(zhǔn)正交線的軸面速度梯度方程即可得到軸面流網(wǎng).通過流線迭代法,在確定軸面流道輪廓之后,可以通過所需時(shí)間很短的迭代計(jì)算過程得到的軸面流網(wǎng).圖1是流網(wǎng)所對(duì)應(yīng)的軸面速度沿軸面流線的分布圖.
