Abstract

PURPOSE:To make it possible to perform a test correctly without raising and falling an object to be tested,by making it possible to introduce water in a water tank into a test tank by compressed air. CONSTITUTION:A water immersion means 20 consists of a water tank 38 provided directly under the test tank 22 in a machine body 14, a water conduit 40 for communicating water in the water tank 38 and the bottom wall 22a of the test tank 22 and a compressed air supply source 42 for supplying compressed air into the water tank 38. When compressed air is sent into the water tank 38 through a direction change-over valve 44 and a compressed air conduit 46, water in the water tank 38 is guided into the test tank 22 to horizontally immerse an object 1 to be tested in water. On the other hand, when the direction change-over valve 44 changed over to exhaust air in the water tank 38, water in the test tank 22 is returned to the water tank 38 through the water conduit 40.

This type of hydraulic test equipment generally includes a test object holding means that holds the test object completely watertight, and an air supply that supplies air into the test object through the test object holding means. and a water immersion means for immersing the test object in water together with the test object holding means. In the prior art, the water immersion means includes a test object holding means provided above the water tank and a lid that moves up and down, and the test object is immersed in water by this lid. However, with this conventional technology, the test object goes deep into the water tank and away from the operator's eyes, and the lifter obstructs the field of view and illumination, so the generation of small bubbles may be overlooked, and the operator has to bend over. It is difficult to perform the work because the work is carried out using the liter, and the structure of the liter is complicated, resulting in high equipment and operating costs.
