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)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比，也可選用不同轉(zhuǎn)速的動力機。jdhuiquan717
(3)水泵轉(zhuǎn)速改變后，其流量(Q)、揚程(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、揚程和功率。 Q、H、N分別代表規(guī)定轉(zhuǎn)速下的流量、揚程和功率。
(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)速會發(fā)生其它事故，故應(yīng)慎用。
(5)水泵轉(zhuǎn)速過分降低時，泵的使用效益低，為此，應(yīng)盡量避免泵在過低轉(zhuǎn)速下運行。用戶應(yīng)按性能曲線圖選擇使用。

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.
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

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).
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、荼時防止空氣吸入泵內(nèi)，起密封作用。
2、抽水時防止水從泵內(nèi)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(fā)現(xiàn)軸套磨損過多，可換軸套。
（五）水泵軸的兩個支承是軸承體內(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)，從而保護軸承，延長使用壽命。

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(xù)方程,根據(jù)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(wǎng).通過流線迭代法,在確定軸面流道輪廓之后,可以通過所需時間很短的迭代計算過程得到的軸面流網(wǎng).圖1是流網(wǎng)所對應(yīng)的軸面速度沿軸面流線的分布圖.
