State the center of test pools 8.Variable-frequency motor 1 can carry out the adjusting of different rotating speeds as needed.
It is from bottom to top in the lateral fluid main flow direction of guide shell 6 when Double-curved-surface stirring machine is run；In guide shell 6
The direction of portion's fluid flowing is from the top down, so cycle is continuous.Between 8 wall surface of guide shell 6 and test pools, arbitrary cross-section
Mean flow rate approximately equal.
Due to being limited by condition, practical impeller and device it is oversized, rotating speed is excessively high, it is difficult to carry out prototype examination
It tests.The impeller pattern is model parameter the parameter conversion of full mold by the theory of similarity, with small model test ratio be actually subjected to through
Ji and practicality.
As preference, the mounting height of the tachymeter 7 is between the depth of water 1/3~2/3 in test pools 8.Tachymeter
Mounted on the outside of guide shell 6, the state of 6 both ends flow instability of guide shell is removed, installs and surveys between the depth of water 1/3~2/3
