Optical fiber distribution box compressive tester buying guide
fiber distribution box compression testing machine, mainly used for testing the physical properties of the fiber optic equipment wiring box, put pressure on the top of the box body, to observe the shape of enclosure variables, determine compressive capacity of box. Choose an appropriate compression testing machine, must first understand the standard requirement of fiber distribution box and the performance characteristics of testing machine.
fiber distribution box is suitable for the cable and wiring connection of optical communication equipment, through the adapter wiring boxes, lead to optical signal light jump line, light distribution function. Suitable for fiber optic cable and wiring tail fiber protective connection, can also be applied to fiber termination point used in the optical fiber access network. According to the standard 'YDT1313 - 2008 broadband access with integrated distribution box 'and' YDT - 2150 2010 fiber optic equipment box 'and so on request, provide housing surface compressive testing machine mechanical strength test of one of the necessary equipment.
to choose a suitable compression testing machine, first of all need to match the appearance of the box dimension and standard pressure value to choose. Such as, according to the standard 'YDT1313 - 2008 broadband access with integrated distribution box 'regulation,' 4. Mechanical and physical performance '6 enclosure, when the body height of 500 mm or less, the top of the box surface should be able to bear the vertical pressure of not less than 200 n, the door is opened, zui outside of the door should be not less than 50 n vertical under pressure. After discharge load, casing damage and deformation. According to this article, we can determine the compressive tester zui to at least a value greater than 200 n, the displacement of at least more than 500 mm. So, we can describe, depending on the fiber distribution box test standards quickly determine compressive tester of the basic technical requirements.
to choose a suitable compression testing machine, not only to understand the fiber distribution box test, for the performance characteristics of testing machine are also a wide variety of choices. Now the mainstream in the market has two big distinction:
1, the choice of operation mode: digital display with microcomputer. Also known as digital compression testing machine microcomputer type compression testing machine, testing data directly display on the LCD screen, the test project is fixed, often used for quality control of the factory. Microcomputer: compression testing machine is zui general compression testing machine, due to the test by computer data acquisition, through the calculation and processing software programs users want zui data, and can be printed out by means of reports. Often used to test institutions, scientific research units, such as new product development.
2, selection of motor, inverter and servo. Compressive tester: frequency conversion system USES frequency conversion motor control system, tensile, compression speed controlled by frequency conversion governor. Compression testing machine servo system: adopt servo motor control system, tensile, compression speed and displacement control more accurate. Servo motor system for servo control system, using the intelligent feedback type operation, can constant speed test, cycle test, programming, testing, etc.
is developed by measuring test equipment co. , LTD. Wuhan fiber optic equipment distribution box compression testing machine, the servo motor system, computer control, imported high-precision sensor test. YouKeYuan and will next month in wuhan. If you have any doubt of choose and buy other fiber distribution box compression testing machine, wuhan is measured welcome your consultation!
