PURPOSE:To inspect the cause for a fault easily, by inserting indicating liquid into a U-shaped pipe, and inspecting the fault from the movement of the indicating liquid. CONSTITUTION:If a tube 4 is removed from a filter 5 and a tube 17 is wound into the filter 5, the local releasing system up to the filter 5 can be inspected and the result gives a measure for exchanging the filter 5 or adjusting an adjusting part 7. If the filter 5 is found to be normal and a pipe 3 is found to be abnormal by the inspection, the suction pipe 3 and the tube 4 are abnormal. If the part (a) of an indicating plate 14 is colored red, the part (b) yellow and the part (c) green, the level difference of indicating liquid 18 in a tube 11 that exists in the red range indicates that the tube is abnormal, the level difference in the yellow range indicates that the tube is cautionary and the level difference in the green range indicates that the tube is normal. |
