Hydraulic reciprocating seal dynamic property detection device and design

Abstract

The invention provides a hydraulic reciprocating seal dynamic property detection device and design. The device comprises a dynamic friction property detection module, an inner leakage detection module and an outer leakage detection module which share a part of a testing device. When a hydraulic cylinder (1) is connected with a first testing cylinder (2) through an S-shaped tension pressure sensor (4), the S-shaped tension pressure sensor only achieves a connection effect, and thus the structure of the outer leakage detection module and the structure of the dynamic friction property detection module are similar. As long as an oil level sensor (8) is additionally arranged on a left gland of the first testing cylinder, the oil level sensor is welded to the left gland of the first testing cylinder through a supporting steel tube. According to the detection device, under the premise that the function requirements of a hydraulic reciprocating structure and a hydraulic execution element are not changed, detection of the dynamic friction property and the leakage property of a hydraulic reciprocating seal in application is conducted according to the normal operation condition of the hydraulic execution element. According to the hydraulic reciprocating seal dynamic property detection device and design, analysis and evaluation of the dynamic property of the hydraulic reciprocating seal can be achieved.

AI Technical Summary

Benefits of technology

This new design allows for better testing of both the pumping rods used by an Hydrolumatic Actuators (HA) system and its bearings that are subjected to high pressures while still being able to work properly. It also includes fused methods to accurately detect changes caused by these movements over time.

Problems solved by technology

This patented technical solution describes a new type of hydrocycling sealed device used in hydropulsive power systems called hydrocracking machines or refrigeration compressor systems. These systems use different ways to monitor the behavior of their components - including the movement of the valve stem within the machine's housing, the presence of lubricant residue inside the closed chamber where the hydrous liquid works together, and changes made overtime caused by factors like temperature fluctuations. Additionally, there exist challenged issues such as unstable flow rates and excessive wear debris accumulation when utilizing these techniques alone.
