Abstract
PURPOSE: To attempt function improvement of a hydro-hiost, by enabling generation of hydraulic shock due to fluctuation of duct resistance to be suppressed to an extremely low level.
CONSTITUTION: At first, open valve 4a and 8a to feed slurry 14 into supply duct 1a under the condition that both low pressure slutty pump 13 and high pressure driving hydraulic pump 3 are operating, and next, open valve 2a, 6a as soon as closing valve 8a, 4a in order to supply duct 1a with driving liquid contained in driving hydraulic tak 10 by means of pump 3, subsequently feeding slurry staying the duct 1a into transfer duct 7. Provide pressure gauge 15aW15c, 16aW16c in each supply duct 1aW1c and return duct 9 of a hydro-hoist in which similar operation has been also applied to supply duct 1b, and 1c. And further composition shall be advanced in such a way as to prevent generation of hydraulic shock, by controlling flow regulation valve 17, 18 in response to the output signal transmitted from each pressure gauge.
