Engineering Testing and Application Record of JNPAT 86mm Gas-Liquid Slip Ring

In the design of high-performance automation platforms, the actual performance of parameters determines the upper limit of the entire system. We conducted a real-world deployment test on a specific JNPAT model (86mm diameter, 249.2mm length), focusing on its coordinated performance under high-pressure operation of a 4-channel liquid circuit and high-load transmission of 9 electrical signals. The test data demonstrates that the slip ring exhibits satisfactory engineering specifications in terms of dynamic contact resistance and fluid pressure loss.

Engineering Test Data Analysis

Dynamic Resistance Fluctuation and Signal Stability: At rated speed, 3 signals were captured using an oscilloscope. The test showed extremely low dynamic resistance fluctuation and zero data packet loss. This means that when transmitting sensitive visual signals or high-speed pulse signals, the slip ring can provide near-wire-connected stability, and with sufficient power from 6 channels (16A), seamless integration of execution and feedback is achieved.

Fluid Flow Rate and Pressure Bearing Test: Static pressure and dynamic cycle tests up to 10MPa were conducted on the 4-channel liquid circuit. The flow channel formed within a 249.2mm length exhibits excellent hydrodynamic characteristics, with minimal turbulence and minimal pressure drop during medium passage. This directly improves the response speed of the hydraulic actuator, which is crucial for automated actions requiring rapid gripping.

Mechanical Life and Installation Compatibility: The slip ring adopts a flange-type mounting design, highly compatible with the interface standards of mainstream automated rotary tables. After simulating millions of rotational cycles, internal contact wear is negligible, and the seals exhibit excellent elasticity. Its 86mm outer diameter allows designers to reserve a larger through-hole space in the center or install other auxiliary pipelines, greatly expanding the flexibility of engineering design.

Through quantitative testing of various key indicators, the JNPAT electrohydraulic slip ring demonstrates extremely high professional adaptability. It supports the requirements of high-frequency, high-load, multi-media rotary operations, providing stable and reliable rotary connection technology support for fields such as lithium battery testing, semiconductor packaging, and precision medical rotary tables.
