The main body of the steel strand test machine adopts the vertical structure, covers a small area, and the constant temperature and vibration-free conditions required by the relaxation test are easy to meet. The test space is adjusted by the screw, the upper beam is stretched through the double column and the work table, how much do you know about the steel strand test machine? Let's tell you about the characteristics and maintenance of the steel strand test machine, let's take a look at it.

First, the characteristics of the steel strand test machine.
1, horizontal horizontal pull structure, two main light bar trapezoidal arrangement, as an upgrade of vertical test machine, improve products, its operation is more intuitive, simple and safe. Extended stretch space, sample length of more than 2450mm, improve the accuracy of the test results. The main frame of 2 times the maximum test force avoids the test error caused by the relaxation of the structural frame and increases the accuracy of the test. Using self-locking worm worm structure, no gap ball screw, compact structure and high efficiency.
2, the use of high stability, high precision import load sensor, reduce the relative error of the test force value.
3, the use of grating digital deformation measurement sensor, fundamentally avoid the traditional analog sensor zero-point drift and temperature drift on the impact of measurement results, time-time measurement of the subtle deformation of the test, to ensure that in the long-term test, the stability of the measurement, better than the traditional displacement hold.
4, steel strand test machine using imported all-digital AC servo motor, to ensure high transmission system efficiency, low noise, smooth transmission.
5, specialized module test software, full open design, graded permission use management, can be networked to achieve data transmission.
6, steel strand test machine full digital closed-loop control and measurement system, the use of all-digital technology, to achieve force, deformation, displacement of three closed-loop control. Test force, deformation measurement of the whole process without gear, resolution of 300,000 yards, can expand the data acquisition channel, high sampling frequency, fast communication rate.
7, the length of the three-valve wedge-shaped fixture, clamped more firmly, with a special release paste, after the experiment is very easy to release.

Second, the maintenance of the steel strand test machine.
1, control cabinet on all the door should not be opened and placed, so as not to dust into the interior, affecting the sensitivity of the measuring body.
2, long-term frequent use may lead to a reduction or quality of oil, should be based on the use of oil every 1-3 months to check the amount. After 15 minutes of operation, observe the left oil window of the control cabinet meter, if the oil surface is lower than the oil window, add the same hydraulic oil to the middle position of the oil window;
3, frequent use of steel stranding test machine to do stretch break test may lead to partial fasteners loose. Tightening should be checked frequently for:
a. There are two L-block pressure plates (a total of 8 pieces) before and after the upper beam and the moving beam (with a clamp plate guide), each of which is secured with 2 screws;
b. 6 screws at each end of the moving beam;
c. Check the tightening degree of the wire rod drive chain every 6 months and adjust the position of the rise and tightening wheel accordingly (after removing the lower panel of the main body);
d. Check the tightness of the oil pump drive belt once a year and adjust it accordingly (after opening the lower door of the control cabinet).
4, according to environmental conditions and frequency of use, every 3-6 months to lubricate the following parts:
a. The wire rod is combined with the base and lubricated with oil No. 100;
b. The wire rod drive chain is lubricated with butter;
c. The screw part of the screw is kept clean and lubricated with butter or molybdenum dioxide;
d.ab both lubrications need to be carried out after removing the lower panel of the main body.
5, on the upper beam and mobile beam each have 2 device jaws for the jaw plate, is an important part of the steel twisting test machine, should be used to often remove the jaw plate and beam contact surface debris, so as not to pull the contact surface. Methods are: remove the pressure plate on the side of the beam, remove the jaw plate, use the oil rag to remove the contact surface of the jaw plate and the beam respectively, apply the appropriate amount of butter and graphite mixed grease, install the clamp plate after tightening the fixed screw of the pressure plate.
Instrument operators should carefully read and understand the maintenance of the instrument, maintenance of the instrument, so that the instrument often keep clean, parts and accessories complete, safe, to ensure the normal operation of the instrument. The above is the characteristics of the steel strand test machine and maintenance of a detailed description, I hope to be able to bring you help, if there are other questions, welcome to inquire.
