Description

Technical Field

[0001] The utility model relates to the field of steering gear solenoid valve debugging, in particular to a steering gear solenoid valve debugging test bench. Background Art

[0002] Steering gears are widely used in vehicle steering and ship hydraulic steering rudders. They enable drivers to achieve greater steering force control with less operating force, offering safe, reliable performance, flexible operation, and ease of use. However, after production, manufacturers must test steering gear solenoid valves to ensure they meet quality requirements. Currently, these testing devices are typically fixed structures, with dedicated test benches for each solenoid valve test item. This results in a large number of test benches, requiring significant floor space and high equipment costs. Furthermore, these test benches are inconvenient for operators to use, and during testing, impurities and dust accumulate on the test benches, requiring regular cleaning to prevent them from sticking to the solenoid valves or test equipment, leading to inaccurate test data.
