Description

Technical Field

[0001] The utility model relates to the technical field of fault diagnosis, in particular to a portable hydraulic fault diagnosis instrument. Background Art

[0002] Proportional valve hydraulic device is a proportional valve. On ordinary pressure valves, flow valves and directional valves, proportional solenoids are used to replace the original control parts. According to the input electrical signal, the pressure, flow or direction of the oil flow is continuously and proportionally controlled remotely. When diagnosing the proportional valve hydraulic device, a fault diagnosis instrument is required;

The shell is provided with a handle, which is rotatably connected to the outer wall of the shell, and the handle can rotate freely on the shell. A support assembly is provided in the shell, and the diagnostic instrument is installed on the support assembly. The bearing device includes a support protrusion, a rotary rod, a baffle, a clamping spring and a handle. A threaded hole is provided on the shell, and the rotary rod passes through the support protrusion and is threadedly connected to the shell. The baffle and the clamping spring are both sleeved on the rotary rod. The support protrusion is used to support the proportional valve hydraulic device installed thereon, and the two ends of the clamping spring contact the baffle and the handle installed on the rotary rod respectively. The device can eliminate the vibration effect during the diagnosis of the proportional valve and improve the accuracy of the diagnosis. The following problems exist in this technical solution:

[0004] When in use, the handle and the shock-absorbing assembly can be used to absorb and damp the instantaneous impact brought by the proportional valve hydraulic device. Since the housing is not easy to fix during use and has poor stability, even if the shock-absorbing effect can be achieved, instability and sliding will still occur, which will affect the diagnosis of the proportional valve hydraulic device and reduce the use effect.

[0005] In view of the above problems, the utility model document proposes a portable hydraulic fault diagnosis instrument. Utility Model Content
