AI Technical Summary

Technical Problem

Hydraulic compressor seals are prone to aging, hardening, brittleness, cracking, and increased surface roughness during use, leading to sealing failure, hydraulic oil leakage, and compressor shutdown.

Method used

A hydraulic compressor control device was designed, comprising an annular detection tube, an elasticity detection mechanism, a crack detection mechanism, and a roughness detection mechanism. The device monitors the elasticity value, surface cracks, and roughness of the sealing ring in real time through a PLC controller and an indicator light system. The device uses components such as a compression elasticity test rod, a permanent magnet spring block, and an electromagnetic adsorption block to detect the status of the sealing ring, and green and red indicator lights to indicate the usage status.

Benefits of technology

It enables real-time monitoring of the sealing ring's status, allowing for timely assessment of the sealing ring's elasticity, surface cracks, and roughness, ensuring the normal operation of the sealing mechanism, preventing hydraulic oil leakage, and guaranteeing the stable operation of the compressor.

Abstract

The application belongs to the technical field of compressors, and particularly relates to a hydraulic compressor control device and a control method thereof, which comprises a shell, an end cover, a control piston, a control piston rod and a liquid output pipe, the control piston and the control piston rod are arranged in the interior of the shell, the end cover is arranged at the opening of one side of the shell, and a sealing ring is arranged at the connecting position of the end cover and the shell. The sealing mechanism of the compressor control device can be elastically extruded, and the elastic value of the sealing mechanism can be judged. The green indicator light and the red indicator light are turned on to respond, so that people can directly judge whether the elastic value of the sealing ring meets the use standard. In addition, the cracks and roughness on the surface of the sealing ring can be detected, and the use condition of the sealing ring can be judged based on the detected values. Furthermore, the use condition of the sealing mechanism of the compressor control device can be predicted through the comprehensive detection structure, so that the working condition of the compressor control device can be ensured.
