Description

Technical Field

[0001] This utility model relates to the field of hydraulic component testing technology, specifically to a hydraulic component testing device that is easy to clean. Background Technology

[0002] Relief valves, servo cylinders, and proportional servo valves are core hydraulic components of construction machinery, and their performance characteristics directly determine the performance of the machinery. Therefore, it is crucial to inspect and maintain high-quality relief valves, servo cylinders, and proportional servo valves, as well as to verify the performance of these components after repair.

[0003] For example, CN220248539U is a hydraulic component testing device that is easy to clean. The device includes an oil tank, and a test oil pipe is provided on the top of the oil tank. It also includes a hydraulic valve installed on the test oil pipe. Four support blocks are fixedly connected to the top of the oil tank and located directly in front of the test oil pipe. The main purpose is to solve the problem that after the hydraulic valve is tested, during the disassembly process, test oil may drip from the oil inlet connector, oil outlet connector, and both ends of the hydraulic valve, which will contaminate the working environment and increase the labor intensity of the cleaning work for the staff.

[0004] During the use of the above-mentioned device, when assembling hydraulic components, oil drips from the interface onto the surface of the oil tank. Even if a collection box is set up to collect the leaking oil, oil will still drip when the hydraulic components are moved. This results in oil residue on the surface of the oil tank, making it difficult to clean. Therefore, we propose a hydraulic component testing device that is easy to clean in order to solve the problems mentioned above. Utility Model Content
