Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] see Figure 1-4 , a hydraulic component seal detection device with self-detection, comprising a body 1, an indicator light 2 is fixedly connected to the top of the inner wall of the body 1, a U-shaped liquid storage chamber 3 is fixedly connected to the inner wall of the body 1, and a U-shaped liquid storage chamber 3 is fixedly connected to the inner wall of the body 1. The interior is filled with electrolyte solution, which accounts for one-half of th...

The invention relates to the technical field of pneumatic hydraulic elements, and discloses a hydraulic element sealing detection device with a self-detection function. The device comprises a machine body, an indicator light is fixedly connected to the top of the inner wall of the machine body, a U-shaped liquid storage cavity is fixedly connected to the inner wall of the machine body, and a bracket is fixedly connected to the inner side of the inner wall of the machine body. According to the hydraulic element sealing detection device with the self-detection function, the inner wall of the machine body is filled with a gas while a hydraulic element is clamped through clamping blocks, when the sealing performance of the hydraulic element is good, an air pressure can generate a certain pressure on the inner wall of the machine body to drive elastic pieces to move towards the inner side, a gas on the inner wall of the bracket is driven to apply a pressure to the inner wall of the U-shaped liquid storage cavity through a flowing groove, the pressure enables an electrolyte solution filled in the U-shaped liquid storage cavity to move towards one side to be in contact with a first reaction column and a second reaction column to generate currents, the currents electrify the indicator light and lighten the indicator light, and therefore the effect of automatically detecting the sealing performance of the hydraulic element is achieved.
Description
technical field [0001] The invention relates to the technical field of pneumatic hydraulic components, in particular to a hydraulic component seal detection device with self-detection. Background technique [0002] With the development of society, in modern equipment, the most typical hydraulic components are used more and more frequently in our life, and the failures of hydraulic components also occur from time to time, especially the failure and wear of solenoid valves. 1. Damage to hydraulic seals is a common problem, and damage to hydraulic seals is generally invisible to the naked eye and needs to be detected. [0003] At present, there are certain defects in the sealing performance testing devices of hydraulic components on the market, and there is a lack of effective means. Most of them use general-purpose friction and wear testing machines to carry out tribological tests on sealing component materials, and the test parameters are related to the actual use of the seal...
