It should be noted that pump signs marked on the head and the use of water lift there is a difference, this is because of water through aqueducts and pipes must be near the resistance loss.

必须注意，水泵标牌上注明的扬程与使用时的出水扬程是有差别的，这是由于水流通过输水管和管路附近时会有一定的阻力损失。

The biggest characteristic of this model is that the hydraulic system pump station, operating console and working clamp installation table can be installed and connected in users sites and dived the test workpiece into the pond, can lift up and down, left and right two directions clamp worktables set 90 degree overturn function, especially suitable for gas pressure test.

本机型最大特点由液压系统泵站，操作控制台和工作夹紧装置台在用户现场安装连接，将试验工件潜入水池中目测，可上下升降，左右两向夹紧工作台设有90度翻转功能，特别适应气体压力试验。◎适用于直通法兰式阀门的密封压力和阀体强度压力性能试验。

As a downstream piping system when the valve opens, reflux valve, when closed, the main medium used to prevent backflow to prevent the pump and drive motor reversal, as well as a container medium discharge; currently the most commonly used is the valve flap around the body Swing Pin rotation flap valve and the valve body along the vertical axis to move lift check valve, but the above two kinds of structures exist in the valve closed, medium speed back quickly from the largest drop to zero, inlet side of the pipe resulted in the rapid pressure rise, resulting Proportional Pressure Reducing Valves in damaging effects on the piping system of water hammer phenomenon, it is generally a diameter of valve production of 50 ~ 500 mm.

止回阀作为管道系统顺流时开启，逆流时关闭的阀门，主要用于防止介质倒流，防止泵及驱动电机反转以及容器内介质泄放；目前使用最普遍的是阀瓣围绕阀体销轴旋转的旋启式止回阀和阀瓣沿着阀体垂直中心线移动的升降式止回阀，但以上2种结构的阀门均存在关闭时介质倒流速度从最大迅速降为零，致使管道进水管一侧内压迅速升高，从而产生对管路系统有破坏作用的水锤现象，所以一般止回阀生产口径为50～500 mm。

With the help of performance test of reciprocating pump, the design for the spring was validated. An experiment-bed was also built to test the poppet valve's lift displacement. The testing results prove that the simulation was in a correct way.

设计了往复泵泵阀试验台；通过对往复泵进行性能测试，对不同弹簧预紧力下阀门升程进行了测定，验证了仿真结果的合理性。

A48SC Type Pound-Grade Full Lift Spring Loaded Safety Valve But how many pump operators know how to perform the manual override and, if they do, how many have practiced this maneuver?

但究竟有多少泵运营商知道如何执行手动，如果他们这样做，有多少人练这个动作？

Pump performance parameters such as flow Q lift shaft power N H n efficiency η speed between a certain relationship.

水泵的性能参数如流量Q 扬程H 轴功率N 转速n效率η之间存在的一定的关系。

For pump power, with the liquid viscosity increases, lift and efficiency, shaft power increases, so sometimes on industrial liquid viscosity viscous heating to make smaller in order to improve transmission efficiency.

对于动力式泵，随着液体粘度增大，扬程和效率降低，轴功率增大，所以工业上有时将粘度大的液体加热使粘性变小，以提高输送效率。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
