In this paper, the results of the practical and performance test of the heat driven pump are presented, which is developed as recovering facility of the waste heat at high temperature level.The heat driven pump consists of the U-type tube with the check valves installed both ends.This pump can transfer liquid and heat simultaneously by cyclic pressure fluctuation in tube, which is induced from the results of the boiling and condensation phenomena in the working liquid.
The experiments are made threefold.At first, a empirical test of copper tubed pump, which simulates a practical use of this pump, is carried out with gas burner heating.Next test that uses a pump made from pylex glass tube, is carried out in order to visualize the flow pattern in tube.Then, a performance test is carried out, using electrical heating.
As a result of these tests, it can be concluded that the working region of this pump depends on the flow pattern of the working fluid in the upper heated tube and the discharged flow rate of this pump is controlled by the rate of supplied heat at the lower heated tube.
