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.

(2)改變轉速的方法：改變皮帶輪外徑或改變齒輪減速器傳動比，也可選用不同轉速的動力機。jdhuiquan717
(3)水泵轉速改變后，其流量(Q)、揚程(H)和功率(N)的變化關系如下式所示： Q1=Q*n1/n H1=H*(n1/n)2 N1=N*(n1/n)3
式中：Q1、H1、N．分別代表轉速改變后的流量、揚程和功率。 Q、H、N分別代表規定轉速下的流量、揚程和功率。
(4)水泵轉速提高后，耗用功率增加，吸上真空度降低，壽命縮短。過分提高轉速會發生其它事故，故應慎用。
(5)水泵轉速過分降低時，泵的使用效益低，為此，應盡量避免泵在過低轉速下運行。用戶應按性能曲線圖選擇使用。

Are able to carry out emergency treatment. Changsha pump-pump reminder can be treated as follows: If the water seal of the pump due to LAX sealing has a slight leakage, but the wear is not too serious, can be on the glass plate or plate on a sand cloth, the water seal of the sealing plane to repair smooth can be, can also be the rubber water seal after the use. However, it should be noted that the contact surface on the water cover and the pump body should be ground to ensure its sealing performance. We must understand the causes of water pump leakage, in order to avoid and even reduce the leakage situation encountered in the work. First, the pump installation is not installed in place will cause water pump leakage phenomenon, so the installation process should be strictly in accordance with the instructions, pay special attention to the water SEAL ring Assembly, the baffle is not installed in place, rubber gasket and cast iron bushing grinding and so on. Second, the working environment is poor, resulting in water pump wear, we must check early to find, in order to correct the replacement. Such as the rubber gasket and bushing end of the wear is not uniform, or the spring soaked in water for a long time.
2、允許吸上真空度[Hs]與必需汽蝕余量[NPSH]r的換算關系：
[Hs]≈10-[HPSH]c
[NPSH]r≈[NPSH]C+0.3
式中：[Hs]-允許吸上真空度 米
[NPSH]C-臨界汽蝕余量 米
[NPSH]r-必需汽蝕余量 米

Easy to rust, reduced elasticity, can also cause leakage. Third. Finally, the machine is old, the water seal internal parts wear, rust and aging failure, is also the reason for the leakage of the pump. We must pay attention to the maintenance and replacement of new parts. PS Winter Friendship Tip: Winter if forgotten or not clean, to timely temperature too high, cooling system water vapor condensation after freezing, may cause pump pump body is frozen, resulting in leakage oh. Stainless steel horizontal mixed-flow pump must pay attention to maintenance after use, for example, when the stainless steel horizontal mixed pump used to put the stainless steel horizontal mixed pump water clean, it is best to unload the pipe and rinse with water. The tape on the stainless steel horizontal mixed-flow pump should also be removed, then rinse with water and dry in the light, do not put the tape in a dark and humid place. Stainless steel horizontal mixed-flow pump tape must not be stained with oil, let alone put some sticky things on the tape. Be careful to check the impeller for cracks.
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成。
（二）泵蓋是泵與進水管相連的零件，其端面與葉輪之間留有規定的軸向端面間隙（在消除軸承軸向活 動間隙以后，保持規定的軸向間隙）。間隙過小產生摩擦，過大則會導致泵內壓力水回流，使泵的效率降低，通過增減調整紙墊達到規定的要求的間隙。延伸搜索：水環真空泵
（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、荼時防止空氣吸入泵內，起密封作用。
2、抽水時防止水從泵內過多的沿軸大量流出。
（四）軸套用來保護軸不使它與填料直接摩擦，若長期使用中發現軸套磨損過多，可換軸套。
（五）水泵軸的兩個支承是軸承體內的軸承，軸承體內存有適量潤滑脂以潤滑軸承。
（六）軸上的擋水圈可防止水沿泵流入軸承體內，從而保護軸承，延長使用壽命。
用途/應用領域
混流泵混流泵是一種比轉速較高的泵型,廣泛應用于農田灌溉,防澇排洪,污水處理,電站冷卻系統等領域.在大流量,低揚程的應用場合下,軸流泵揚程,流量變化范圍小,區窄,抗汽蝕性能差,使用混流泵代替軸流泵,能夠在發揮軸流泵優點的基礎上補償這些缺點,從而取得更好的使用效果.
高比轉速混流泵的設計方法
軸面流動計算
采用流線迭代法求解軸面流動.流線迭代法基于沿任意準正交線的軸面速度梯度方程和流體運動的連續方程,根據各子流道流量相等的原則,迭代求解沿準正交線的軸面速度梯度方程即可得到軸面流網.通過流線迭代法,在確定軸面流道輪廓之后,可以通過所需時間很短的迭代計算過程得到的軸面流網.圖1是流網所對應的軸面速度沿軸面流線的分布圖.
