Embodiment Construction
[0032] Such as figure 1 , figure 2 As shown, a high-pressure turbine working blade water flow automatic measurement system includes a water flow measurement device with a first measuring cylinder and a second measuring cylinder, and a first liquid level sensor with a float is arranged in the first measuring cylinder. A second liquid level sensor with a float is arranged in the second measuring cylinder; the first liquid level sensor and the second liquid level sensor are connected to the computer through the A / D converter; the output end of the control button is collected through digital signal The card is connected with the computer, and the computer is connected with the measurement system through the digital signal output card. Both the first liquid level sensor and the second liquid level sensor are magnetostrictive liquid level sensors, the model of which is: HT-FPST1G00400C2A1L1AB. The first measuring cylinder is used to measure the water volume of the exhaust seam of...

The invention relates to an automatic measuring system of the water discharge of high-pressure turbine work blades and a measuring method thereof, which belong to the technical field of an aeroengine. The measuring system comprises a water-discharge measuring device, the water-discharge measuring device is characterized in that: a first liquid-level sensor with a floater is arranged inside a first measuring cylinder, and a second liquid-level sensor with a floater is arranged inside a second measuring cylinder; the first liquid-level sensor and the second liquid-level sensor are connected with a computer through an analog / digital (A / D) converter; and an output end of a control button is connected with the computer through a digital quantity signal collection card, and the computer is connected with the measuring system through a digital quantity signal output card. The measuring method comprises the following steps that: starting a water pump, and detecting an input signal; starting the measuring system to measure the water discharge; timing, retarding, collecting data and starting water discharging; and judging whether a water level required in the process is reached, and judgingwhether another blade is measured.
Description
technical field [0001] The invention belongs to the technical field of aero-engines, and in particular relates to an automatic measurement system and a measurement method for the water flow of working blades of a high-pressure turbine. Background technique [0002] At present, in the prior art, all important technical parameters such as life and state of turbine blades are controlled by computer. However, the water flow measurement of the turbine blades still adopts the old-fashioned manual operation method, and a special water flow measuring instrument is used for measurement. The operator observes the liquid level of the glass tube at the front end of the water flow measuring instrument, records the water level value on paper, and then sorts out the data and enters it into the computer. This measurement method has disadvantages such as inaccurate data reading and prone to entry errors in the process of entering the system. Contents of the invention [0003] Aiming at t...
