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 debation, the spring force of the water seal is insufficient or broken and other faults.

(2)改變轉(zhuǎn)速的方法：改變皮帶輪外徑或改變齒輪減速器傳動(dòng)比，也可選用不同轉(zhuǎn)速的動(dòng)力機(jī)。jdhuiquan717
(3)水泵轉(zhuǎn)速改變后，其流量(Q)、揚(yáng)程(H)和功率(N)的變化關(guān)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(zhuǎn)速改變后的流量、揚(yáng)程和功率。 Q、H、N分別代表規(guī)定轉(zhuǎn)速下的流量、揚(yáng)程和功率。
(4)水泵轉(zhuǎn)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(zhuǎn)速會(huì)發(fā)生其它事故，故應(yīng)慎用。
(5)水泵轉(zhuǎn)速過分降低時(shí)，泵的使用效益低，為此，應(yīng)盡量避免泵在過低轉(zhuǎn)速下運(yùn)行。用戶應(yīng)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 b 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 immediaby 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 b.
2、允許吸上真空度[Hs]與必需汽蝕余量[NPSH]r的換算關(guān)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 bs: (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(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(nèi)，從而保護(hù)軸承，延長使用壽命。

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.
