Description

Technical Field

[0001] The invention relates to the technical field of hose testing, in particular to a hose finished product performance testing device. Background Art

[0002] A hose is a type of tubular rubber product used to transport gas, liquid, slurry or granular materials. It consists of an inner and outer rubber layer and a skeleton layer. The skeleton layer can be made of cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. The inner and outer rubber layers of a general hose are made of natural rubber, styrene-butadiene rubber or butadiene rubber; oil-resistant hoses are made of chloroprene rubber and nitrile rubber; acid-resistant, alkali-resistant and high-temperature resistant hoses are made of ethylene-propylene rubber, fluororubber or silicone rubber. The hose structure is usually divided into: an inner rubber layer, an outer rubber layer and a skeleton layer. The inner rubber layer directly bears the wear and erosion of the conveying medium; the outer rubber layer protects the inner body of the hose from damage and erosion by the external environment; the skeleton layer is the pressure-bearing layer of the hose, which gives the hose body strength and rigidity. The working pressure of the hose depends on the material and structure of the skeleton layer.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] When in use, when the pressure resistance performance test is performed: the hydraulic cylinder 4, the circular plate 3, the pressure sensor 13 and the display 21 cooperate to test the pressure resistance performance of the hose. When the pressure resistance test is performed, the hose is placed between the two circular plates 3, the rubber ring 6 wraps the outside of the hose, and the airbag 7 is inflated through the curved pipe 8. The airbag 7 bulges and fits tightly against the inner wall of the hose, which plays a role in positioning the hose. Then, the hydraulic cylinder 4 is started through an external switch, and the hydraulic cylinder 4 pushes the fixed plates 5 on both sides to move relative to each other, so that the circular plate 3 relatively squeezes the hose. The pressure sensor 13 on the circular plate 3 detects the pressure. When the hose is taken out and bent or broken, the squeezing is stopped, and the pressure sensor 13 displays the detected value on the display 21;

The motor 111 drives the threaded rod 112 to rotate, and drives the slider 113 to move downward. The slider 113 drives the frame 1 to descend as a whole into the water tank 2 through the connecting plate 115. Before entering the water tank 2, the valve 9 on the airbag 7 is opened, and the gas injected by the curved pipe 8 will enter the interior of the hose. The air pressure data detected by the air pressure sensor 14 on the circular plate 3 is used to control the size of the air pressure inside the hose, and then the valve 9 can be closed. At the same time, the cooperation of the airbag 7 and the rubber ring 6 can form a closed chamber inside the hose. The frame 1 descends into the water. By observing whether there are bubbles on the surface of the hose, it can be judged whether its sealing is intact. Then the motor 111 is reversed to drive the frame 1 upward, and the blower 17 blows the hose through the vertical pipe 18, the horizontal pipe 19 and the nozzle 20 to dry the moisture on the surface of the hose.
