The relevant parts may be replaced as appropriate to troubleshoot. And if the pump damage is very serious, there is no repair conditions on the way, you can put the pump into, outlet pipe directly on, in order to make full use of the natural circulation of hot and cold water temporarily so that the engine to maintain a normal temperature; or use an inner tube or bucket as a container to secure it firmly, and then draw two hoses from the container, One is connected to the inlet of the engine and the other to the outlet of the engine, and the other end of the two tubes is inserted into the container. Secondly, the hose should be fixed firmly. If only the pump shell produces cracks and leaks, the cracks can be treated clean, and then glued with adhesives. For emergency use, egg cleaning and cement can be mixed into sticky groups applied to the cracks, after a few minutes of solidification can be used. Also, the construction machinery driving or operation process, the water seal leakage of the pump is also a common thing. As long as there is no damage to the hydrosphere or swelling deformation, the spring force of the water seal is insufficient or broken and other faults.
*技術參數
(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。

Pipe caliber and so on. The third step: according to the above requirements to choose the pump, so it is more perfect. Of course, this is only a rough choice, a detailed selection method is still many, you can call our company. It is possible to encounter water pump leakage situation, if so, what should we do? Is there any good way to deal with this sudden situation? No hurry, Changsha pump-pump for you one by one way. First of all, the pump is operating when there is a leak, we must pay attention to a point, do not immediately stop the pump work, should keep it at the lowest stable speed, at the same time to the cooling system side to add water edge, so that the engine cooling, short time, slow driving, drive to the nearby hideout and then eliminate. In addition, when opening the lid of the water cover to add water, to put a cover above it, to prevent the water vapor that is coming out oh. When we were using the pump. If the sudden pump shell rupture and leakage, or the pump inside the machine damage and loss of pump water action.
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

And try to shorten the length of the suction pipe. Secondly, the inlet pipe should be sealed and reliable. Bottom valve and glue pipe safety rope fastened. Water source for the channel, the bottom valve should be higher than 0.5 meters below the bottom, and add mesh to prevent debris into the pump. The third is that when the machine pump belt drive, the tight edge of the belt should be under, in order to improve the transmission efficiency. The pump impeller steering should be consistent with the direction of the arrow. The shape and structure of the guide vane mixed-flow pump are near the axial flow pump. Check the pump should pay attention to three points: (1) pump shaft should be able to rotate flexibly, no impact sound, pump shaft radial no obvious shaking, need to add sufficient lubricating oil. (2) Check the water inlet hose has no breakage, if there is cracking to timely adhesion repair. Check that the fastening bolts are loose and tighten the loose bolts. (3) Submersible pump motor winding, cable insulation must meet the requirements, in order to use. Troubleshooting methods: (1) do not absorb water or no effluent, mostly because the bottom valve is stuck, the filter water part is silted; the height of the suction water is too high or the suction pipe leaks;
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.
