    YY0500-2021 Artificial Vascular Membrane Water Penetration Tester 1.
    Instrument Features This equipment is a testing equipment for testing the performance of the manufacturer's products
    .

    It is composed of programmable controller, touch screen, force sensor, transmission device, on-board printer, etc.
    It provides Chinese and English menu display, and has man-machine dialogue to set various parameters and automatically run the test mode
    .

    In addition, a production unit is added, and the production batch is input by machine, so that the test results are more standardized and standardized
    .

    In terms of information security, three-level passwords are used to make information safe and reliable
    .

    The test control range includes: nominal capacity, core rod displacement, print setting, test, up, down, time, calibration, verification and other function settings
    .

    With the on-board printing test, the test load and sliding data (initial force, average force, maximum thrust) can be displayed in real time
    .

    The test results are automatically judged, and if they fail, the automatic buzzer alarm will be activated, and the test data and results will be printed out by the printer for analysis
    .

    2.
    Test principle: Fix a piece of the artificial blood vessel film sample to be tested on the flange ring with a ring clamp, and press the other flange to compress the film sample.
    During the test, the liquid is continuously added and pressurized, and the precipitation penetrates into the 200ML measuring cup.
    Inside rear balance weighing three, test standard: YY0500-2021 four, technical parameters: operation interface: simplified Chinese/English test standard: YY0500-2021 pressure sensor: 0-50kpaN (test can be set by software) time timer: touch screen display Fixture: 1 set of diameter 10-90MM can choose different areas according to different requirements Balance: 0-500 grams can choose other specifications according to requirements; test software: 1 set of product Net weight: 15kg Dimensions: 430 × 390 × 650 (mm) power supply : AC90V-240V/50Hz (adaptive wide voltage) Machine power: 70W Programmable controller: PLC control system Touch screen: 7 inch Wei Luntong color touch screen Force measuring mechanism: Built-in printer: Embedded printer 1 The flow rate of water through a given area of ​​a sample of the artificial blood vessel is measured at a given pressure
    .

    2 Instruments include: YY 0500-2004/ISO 7198:1998a) Flow measurement device, such as a container that can be weighed, with an accuracy of not more than 2% of the full scale; Note: In order to meet the flow requirements of the flow, more than one such a device
    .

    b) Pressure measuring device, the upper limit of pressure sensor range is 19 kPa (140 mmHg) and the accuracy is ± 0.
    3 kPa (± 2 mmHg); c) Sample fixing device, which meets the following requirements: 1) The film that the fixing device can hold The sample area is 10-90MM (different areas can be selected according to requirements and only the fixture can be changed); 2) The structure of the sample is a round or square strip; Note: If the sample tested is very narrow, the sample can be made into a rectangle
    .

    In this case, it should be noted on the test report, and the accuracy is ±1% of its size
    .

    The orientation of the sample should also be noted
    .

    3) A length of at least 6 times the bore diameter in the test line above the sample shall be straight and have no change in diameter; 4) Leaks around the sample shall not be recorded
    .

    d) During the test, clean, filtered, room temperature water is required for the sample holder
    .

    3 Sampling and Chengsi procedures require that the artificial blood vessel to be tested needs to be wetted with clean filtered room temperature water before testing
    .

    Place the sample on the stationary apparatus and pull the sample taut until there are no wrinkles.
    Note: The effect of stretching the sample can be achieved by clamping, pulling by gravity, or by narrowing the platen
    .

    This stretch should be close to the condition of use.
    Once there are wrinkles, most of the wrinkles should be smoothed out
    .

    Turn on the water flow system and adjust the pressure value to obtain a water pressure of 16.
    0 kPa1O.
    3 kPa (120 mmHg ± 2 .
    .
    Hg), the pressure value is displayed on the pressure measuring device
    .

    When the system is working stably, measure the water flow through the sample within 60±1s
