Water hammer prediction system and water hammer prediction method in piping

摘要

PROBLEM TO BE SOLVED: To provide a pipe water-hammer prediction system and water-hammer prediction method capable of performing an easy and positive prediction of possibility of occurrence of water-hammer and its occurrence place.SOLUTION: Drains discharged out of steam traps 42, 43 and 44 are recovered to a drain recovering pipe 10 through drain connection pipes 12, 13. Then, each of sensors 32, 33 and 34 for detecting a temperature and a pressure within the pipe is installed at a place just near the upstream of each of the steam traps. When it is judged that steam in the pipe is kept under saturated state on the basis of the temperature data and the pressure data got from the sensor 33, for example, a control part 6 predicts that a water hammer is generated at the water hammer occurrence prediction places P2, P3 and performs an informing processing for displaying a mark indicating that a dangerous state occurs at a top plan view of a piping drawing displayed on a screen of a monitor 8.SELECTED DRAWING: Figure 1
