Research on water hammer protection for a long-distance water supply system of a deep well pump group This paper is based on the hydraulic characteristics of the multi-pump group, high head, and small flow of a long-distance water supply system in a deep well pump group. Fisrtly a calcula...
To realize the accurate control of water hammer in pipes by valve stroking, based on basic differential equations of water hammer subjected to initial and boundary conditions, the traveling solution of wave equations in finite region was applied to the linear water hammer problem. With the given ...
modeling, and experimental verification. The hydraulic shock and water hammer in the pipe of the electro-hydraulic exciter will be caused by the fast switching speed of the rotary valve port state
The critical review presented here exclusively covers the studies on battery thermal management systems (BTMSs), which utilize heat pipes of different structural designs and operating parameters as a cooling medium. The review paper is divided into five major parts, and each part addresses the role...

Phosphate dosing is used by water utilities to prevent plumbosolvency in water supply networks. However, there is a lack of knowledge regarding biofilm formation on lead and plastic materials when phosphate concentrations are modified in drinking water s
heavy equipment. It can be used in installing glass curtain wall, petrochemical pipes, railway construction, machine inspection and maintenance in workshop, electric power construction or municipal construction. Its application in Shanghai world expo is the best description...
a pipeline is slow. This movement can be ignored in comparison with the quick phenomenon of the travel of the ' waterhammer ' pressure waves under transient analysis. Therefore, any air pockets can be assumed to remain in their original position during the time-scale of the hydraulic ...
In this study, transient pressure in piped liquid due to waterhammer is a function of structural restraint at elbows. To study the effect of this phenomenon on polyethylene elbowed pipe networks, experimental tests were performed on polyethylene bent pipes, either in the absence or presence of a...
Foot valves are also used on deep well installations to help protect against loss of prime in the well piping system. Foot valves and check valves in water piping system can also help reduce water hammer noise. Since you won't normally see the foot valve on well piping (it's down in th...
