Description

Technical Field

[0001] The utility model belongs to the field of hydraulic system pipelines and relates to an installation structure of a flow sensor and a pressure sensor in a hydraulic system. Background Art

[0002] The pressure and flow monitoring in the hydraulic system pipeline is a key link to ensure the efficient and safe operation of the system. The pressure monitoring in the hydraulic system pipeline is based on the principle of liquid static pressure transmission, and the working state of the system is reflected by measuring the static pressure of the liquid in a closed container. The flow monitoring is based on the principle of pipeline flow detection technology, and the flow velocity and flow rate of the medium are measured by installing sensors in the pipeline.

[0003] The pressure and flow monitoring in the hydraulic system pipeline is an important part of system maintenance and management. By installing a pressure sensor and a flow sensor, the changes in pressure and flow in the system pipeline can be monitored and recorded in real time. This helps to timely detect problems in the system and take corresponding measures for repair and adjustment, so as to ensure the stable operation of the system and extend its service life. At the same time, regular inspection and calibration of the monitoring equipment are also important measures to ensure the accuracy and reliability of the monitoring data.

[0004] However, for the hydraulic system pipelines on an aircraft, there is no corresponding device for connecting and fixing the sensors to the hydraulic pipelines. In actual applications, engineers will weld the mounting brackets of the pressure sensors and temperature sensors to the hydraulic system pipelines, which will cause problems such as damage to the system pipelines and inconvenience for replacement.
