Oil measuring indicator for hydraulic pipeline and detecting method of indicator

Abstract

The invention relates to an oil measuring indicator for a hydraulic pipeline and a detecting method of the indicator, belonging to the field of mechanical testing. The large cavity end of a cylinder body is in threaded connection with a sealing cylinder head which is in threaded connection with a liquid filling device, and a small cavity oil replenishing device is in threaded connection with the small cavity end of the cylinder body; the T-shaped inner end of a piston of a T-shaped moving steel rod system is slidably connected with the inner part of the cylinder body, while the outer end is located outside the cylinder body; one end of the moving steel rod system is located in a seat on the sealing cylinder head, and the other end of the moving steel rod system is located in piston of theT-shaped moving steel rod system; the two ends of an indicating pipeline are respectively connected with connecting holes in the large cavity and the small cavity of the cylinder body in a sealing manner, and the indicating pipeline is filled with an indicating medium; an annular piezoelectric ceramic is fixedly connected with a pressure signal conversion piston and an opening of the indicating pipeline. The oil measuring indicator for the hydraulic pipeline and the detecting method of the indicator have the advantages of novel structure, high practicability and wide application range, provideconvenience for maintenance of various hydraulic pipelines, save manpower and material resources, and can greatly improve work efficiency in actual production and application.

Description

technical field [0001] The invention belongs to the field of mechanical testing, and in particular relates to detection and detection of incoming oil from hydraulic pipelines of engineering machinery. Background technique [0002] With the development of construction machinery, hydraulic technology is widely used. When a failure occurs in a hydraulic circuit, on-site diagnosis usually adopts empirical diagnosis, logical analysis, and detection. means to quickly diagnose the cause of the fault. This process is accompanied by a large amount of disassembly work, the oil circuit diagnosis is relatively complicated, and the maintenance cost is relatively high, which wastes a lot of manpower and material resources. In the process of overhauling the hydraulic pipeline, it is difficult to know the flow direction and other parameters of the hydraulic oil in the pipeline, which brings a lot of inconvenience to the fault diagnosis. If an indicating instrument is installed on each oi...
