The oil collecting groove 13 can collect the fluid flowing out from the gap between the inner surface of the bearing platform 1〇, the lateral static oil chamber support 11 and the outer surface of the support seat 12, and recover the fluid to the oil pump via the oil return pipe 14. 4〇 Complete the circulation of the oil circuit. The sensor includes a temperature sensor 31, a flow sensor 32, and pressure sensors 33, 34. The oil supply and flow path system includes an oil supply pump 4, a fuel tank 401, a strainer 402, a fine filter 403, a three-point group 404, a pressure valve 405, a check valve 406, an accumulator 407, and a pressure gauge 408. The supply fluid is pressurized from the oil tank 401 after being pressurized by the oil supply pump 40, firstly filtering the fluid impurities through the strainer 4〇2, and then the fluid passes through the three-point group 404, and the three-point group 404 has the functions of filtering, regulating and lubricating the official road. . The flow path system prevents the fluid from flowing back with the check valve 4〇6, sets the maximum rated pressure with the pressure relief valve 405, and controls the pressure of the fluid in the flow path system according to the pressure gauge 4〇8. The supply fluid then passes through an accumulator 4〇7 to stabilize the pressure of the fluid, the check valve 406 prevents backflow at the inlet of the accumulator 407, and exits the accumulator 407 with a fine filter 403 for re-filtration of the fluid in the fluid. Impurities. The ## and data extraction system is divided into two parts: hardware and software. The hardware package contains the data capture card 501, the signal junction box 502, the cable 5〇3 and the computer host 5〇4. The software includes a man-machine interface and signal processing and analysis code. 12 Correcting the residual sheet supply fluid is pressurized and discharged by the oil supply pump 40, and is supplied to the static pressure load base through the flow path system in two separate flow paths, which is through the throttle distributor 20' to the capillary officer and the small hole After any type of throttle adjusts the fluid pressure, after entering the oil chamber 105 of the lateral static pressure oil chamber support 11, the gap between the inner surface of the lateral static pressure oil chamber support 11 and the outer surface of the support seat 12 is closed. The fluid flows out and then flows back into the oil collecting tank 13 'flowing in the oil chamber 1〇5 and the gap for use as a lateral positioning of the load platform. The fluid of the other flow path is accurately measured by the pressure difference and the flow rate to the oil chamber 1〇4 of the carrying platform 1〇. The temperature sensor 31 measures the inflow and outflow temperatures before the test piece is to be tested, the pressure sensors 33, 34 measure the inlet and outlet pressures of the fluid passing through the device under test 3, and the fluid enters the lateral static pressure oil chamber. The inlet pressure of the oil chamber 105 supporting the n is measured by the flow sensing factor 32 after the component 30 to be tested. Then, the supply fluid enters the load-bearing platform 1〇 from the inlet flow passage 107, and flows into the oil chamber 1〇4 from the outlet flow passage 1〇8 to flow out in the gap between the oil chamber 104 and the outer surface of the support seat 12, and is carried by the load. A voltage-regulating liquid film is formed between σ 10 and the support base 12. The injected fluid flows into the oil collecting tank 13, and the fluid is recovered to the fuel tank 4〇1 for reuse by the oil return pipe 14. When the weight 16 is added to the load bearing platform 10, the pressure in the oil chamber 104 of the load bearing platform 1 increases, and the pressure in the oil chamber 1〇4 is conducted to the outlet of the component to be tested 3〇, so that the outlet pressure of the component 30 to be tested is increased by the same amount. Therefore, the flow rate is changed, and the inlet pressure, the outlet friction force, the flow monthly repair, the quantity and the temperature of the component to be tested 30 are obtained by the measurement of the weight of the load on the load platform by the measurement of the weight of the load on the platform. Equal signal. The voltage signal of the sensor is connected to the signal junction box 502 by a signal isolation line, and is connected to the data acquisition card 5 (U through the data capture card 5()1) in the computer host 5〇4 via the cable 503. The analog signal of each sensor is converted into a digital signal. The secret constant of the secret signal is the inlet pressure of the component %, the outlet pressure, and the pressure and flow value of the lateral static pressure oil chamber supporting the U oil chamber. The calculation is entered into the calculation, and the flow resistance of the component to be tested is obtained. The temperature value is brought into the program to calculate the fluid reduction, and the viscosity yarn and the flow resistance are brought into the program to calculate the axis of the component 3G, and The man-machine interface is displayed on the computer screen. The above description shows the design of the flow resistance and throttling parameters of the component to be tested. For a large number of components to be tested, use the fifth figure. The parallel quantity shown is difficult to integrate 'the measuring instruments are integrated together, and it becomes the multi-channel sub-supporting platform. Each platform has the form of oil chamber structure with independent support. The supply fluid is discharged from the oil supply pump 40. Oil dispenser will supply fluid In order to stabilize the _ force, the wire is not _ flow. The pressure oil enters the independent cake platform 1〇 and the exploration support oil chamber u, each flow channel is divided into two flow paths, and the flow is passed through the secret system. The road is supplied with a static pressure load base, and after the fluid pressure is adjusted by the throttle distributor 2 () 1, the oil chamber 106' entering the lateral static oil chamber support 111 is supported by the lateral static pressure oil chamber m 1334968 曰Correction of the inner surface of the page--------------^ and the outer surface of the support base (2) __ outflow, and finally flow back into the oil collecting groove 13, in the oil chamber 1〇5 and the gap The fluid pressure flowing inside is used as the lateral positioning of the load platform. The fluid of the flow path is used to measure the pressure difference and the flow rate for calculating the throttling parameters and the flow resistance, and the pressurized fluid is measured in the middle. After the pressure difference and the flow rate, the oil chamber 104 flows to the load platform 101 for carrying the weight, and the load weight is used to adjust the oil chamber pressure of the oil chamber 104. The temperature sensor 311 is assembled before the component to be tested 3〇1 For measuring the inflow and outflow temperatures, using the pressure sensors 331, 341 to measure the inlet pressure of the fluid passing through the component 301 to be tested and The port pressure, and the inlet pressure of the fluid entering the oil chamber 1〇5 of the lateral static pressure oil chamber support 111, the flow sensor 321 is assembled to the flow path of the component to be tested 3〇1 for measuring the flow rate. The sensor measures and records the flow rate through the element to be tested 301, and the inlet pressure, outlet pressure and temperature of the inlet end and the outlet end, and converts the analog signal into a digital signal via the data capture card 501, and then transmits the signal to the digital signal. The computer host 5〇4, calculated by the formula, will measure the measurement result through the human-machine interface, and the 3待1 throttling parameter or flow resistance of the device to be tested is displayed on the screen. [Simplified illustration] Figure 1 shows the flow parameters and The oil pressure system diagram of the flow resistance measuring instrument. The second figure is the current flow parameter and the current resistance measuring instrument. Figure 3 is the flow chart and the bearing platform and lateral static pressure of the flow resistance measuring instrument. The oil chamber supports a perspective view. Figure 4 is a schematic diagram of the use of the flow parameters and the flow resistance measuring instrument in measuring the components to be tested. 15 1334968 Ρ%)2巧τΕΙ修if.Back page change Figure 5 is the turbulence parameter and flow resistance measuring instrument in the measurement of the parallel component of the test component
