Abstract
The invention discloses an impact jet pressure and vibration composite measuring device and an impact jet pressure and vibration composite measuring method. The impact jet pressure and vibration composite measuring device comprises an impact jet generating device, a measuring head, a charge amplifier, a data acquisition and transmission card and an upper computer. The impingement jet flow generating device generates impingement jet flow, the measuring head monitors the pressure of the impingement jet flow, the measuring head is connected with the charge amplifier, the charge amplifier is connected with the data acquisition and transmission card, the data acquisition and transmission card is provided with a wireless data transmitting module, and data is transmitted out through wireless signals. The upper computer is provided with a wireless data receiving module for receiving jet pressure data from the data acquisition and transmission card, the upper computer is provided with LabView software for analyzing and processing the jet pressure data to obtain impact jet pressure and vibration data, and the pressure data are displayed on a display screen of the upper computer. The vibration data are stored in the upper computer in the form of a table. According to the impact jet flow pressure and vibration composite measurement device and the pressure and vibration composite measurement method thereof, the transient pressure of the impact jet flow and the pressure change and vibration signals of the impact pressure within a period of time can be obtained at the same time, and the instantaneous impact water pressure and pressure change of the jet flow can be monitored in real time; the problem that jet impact pressure is difficult to monitor in real time in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of monitoring equipment, in particular to an impact jet pressure vibration composite measurement device and an impact jet pressure vibration composite measurement method. Background technique [0002] High-pressure water jet technology is a new type of technology that uses high-speed water as the energy carrier. As a tool for cleaning, cutting and crushing, jet has its unique advantages. It is widely used in light industry, machinery, construction, mining, petroleum, Chemical industry, nuclear energy, military industry, aerospace, automobile and medical industries. [0003] Jet impact mode and impact pressure are important parameters for various operations. Many operations use impinging jets, because nozzle wear, target distance and jet inclination changes during the working process will affect the impact pressure of the jets, thereby affecting the operation effect. Therefore, real-time monitoring of jet i...
