Internal leakage detection equipment and device for hydraulic oil cylinder

Abstract

The invention relates to a piece of internal leakage detection equipment and device for a hydraulic oil cylinder. The internal leakage detection equipment for the hydraulic oil cylinder at least comprises a cylinder barrel, a piston rod assembly installed inside the cylinder barrel in a matched mode, and a speed detection mechanism fixedly installed in the cylinder barrel and used for sensing the movement speed of the piston rod assembly. By the adoption of the internal leakage detection equipment and device, accurate judgment data are provided for internal leakage of the hydraulic oil cylinder.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a hydraulic cylinder internal leakage detection device and a hydraulic cylinder internal leakage detection device equipped with the device. Background technique [0002] As the executive component of the hydraulic system, the hydraulic cylinder is widely used. In the actual use process, there are oil cylinder leakage faults, and the oil cylinder leakage is divided into two types: external leakage and internal leakage. Once the oil cylinder leaks, corresponding measures must be taken in time to ensure the normal operation of the hydraulic system. Therefore, it is necessary to judge in time whether the oil cylinder is leaking. [0003] External leakage will cause environmental pollution and waste of resources. External leakage is easy to find, and correct judgment can be made only by careful observation. The internal leakage will affect the technical performance of the hydr...

AI Technical Summary

Problems solved by technology

If the amount of internal leakage is small and the frequency of reciprocating motion is extremely low, it is impossible to judge whether there is internal leakage through observation

If the amount of internal leakage is large and the frequency of reciprocating motion is high, it is difficult to distinguish the frequency of motion by observation

The above analysis shows that this method can determine whether there is internal leakage and the degree of internal leakage, but cannot quantify the amount of leakage in the hydraulic cylinder

If it is used to detect the internal leakage of oil cylinders of different specifications, there will be certain problems in the judgment of the degree of leakage in the oil cylinder
