Problems solved by technology
[0003] In summary, the existing problems in the prior art are: 1. Using ordinary high-pressure water pumps to pressurize and relieve pressure, manual control of pressure and time has low work efficiency and low precision; 2. Without intelligent control and recording devices, it cannot The whole process of pressure is recorded by computer; 3. The strain, deformation, pressure, flow and temperature monitoring equipment of the penstock are independent. Changes of various parameters in the pressure stage

The invention discloses an intelligent measurement and control system and method for a hydraulic pressure test of a hydraulic pressure steel pipe. The system comprises a hydraulic pressure loading and unloading control device and a measurement and control device. Controllable and stable water pressure is provided for the pressure steel pipe through servo control of the gas-liquid pump; under the action of different water pressures, the measurement and control device collects and records the stress, deformation, water pressure, water flow, water temperature and the like of the pressure steel pipe and action time in real time; the pressure servo control of the pressure steel pipe water pressure test is realized, the real-time acquisition of a plurality of different types of sensors integrated in one acquisition instrument is realized, the intelligent monitoring of the whole process of the water pressure test is realized through a computer and special software, the relation curve between any parameters is displayed in real time, the precision is high, the fluctuation is small, and the accuracy is high. The stabilizing time is accurate and controllable, the operation is convenient, and the device can be widely applied to hydrostatic tests of pressure vessels.
Description
technical field [0001] The invention relates to the technical field of metal pressure vessel testing equipment, in particular to an intelligent measurement and control system and method for hydraulic pressure testing of hydraulic pressure steel pipes. Background technique [0002] Pressure steel pipes (including bifurcated pipes, connecting pipes, special-shaped pipes, etc.) are mostly used in the water supply of large and medium-sized water conservancy and hydropower projects. For high-head and large-diameter pressure steel pipes, a hydraulic test must be carried out after manufacturing and installation. The stress state and deformation characteristics of each part of the pressure steel pipe comprehensively check whether the working state of the pressure steel pipe meets the design requirements. During the hydraulic test, the deformation, stress, hydraulic pressure, flow rate, temperature and duration of the penstock should be monitored in real time. The current hydraulic ...
