Description

Technical Field

[0001] The utility model relates to the technical field of speed meters, in particular to a device for detecting hydraulic pressure difference of a marine speed meter. Background Art

[0002] Modern ship speedometers generally integrate three equipment modules: differential pressure speed measurement, electromagnetic speed measurement, and satellite navigation speed measurement. Among them, the differential pressure speed measurement device has a simple structure, is stable and reliable, and is an indispensable equipment module for the speedometer. The speedometer is a device that requires regular inspection. The performance indicators after regular inspection are generally tested and calibrated by sea trials after installation. If a problem occurs, the entire device needs to be disassembled and re-inspected, which is time-consuming, labor-intensive, and costly. Since the hydraulic sensing device components in the equipment are relatively precise and have high assembly requirements, it is not uncommon to re-inspect after sea trials.

[0003] When the pressure differential speed measuring equipment senses a speed within the range of 50 knots, the water flow and static pressure difference are within the range of 0 to 200 KPa. At a low speed of 2 knots, the output pressure difference change rate is about 0.2 KPa / 0.2 knots. As the speed increases, the pressure difference change rate increases. In summary, the accuracy of the output hydraulic pressure difference of the detection and calibration equipment needs to reach 0.2 KPa. Currently, only water tunnel devices can do this. Not only are they expensive, large in size, and inconvenient to control, but their maintenance and use costs are also high. Domestic speedometer manufacturers and repair manufacturers do not have similar high-precision detection and calibration equipment. In view of this, in-depth research on the above issues led to the creation of this case. Utility Model Content
