Product Description

universal Testing machine is a new material lab test machine that combined with the electronic technology and mechanical transmission, it has accurate load speed, range of force measurement,Has high accuracy and sensitivity for the load, displacement measurement and control, it also can be tested the constant-velocity loading,constant- velocity displacement. This machine issimple to operate, especially suitable for controlling quality in production line,

Main Technical Parameter

Main components: frame, loading systems, measuring systems, data processing systems, fixtures and accessories, the most important are: load, measuring and data processing;

Instrument Configuration
Standard configuration: hosts, computers, universal fixture, professional software and communication cables
Optional accessories: standard pressure roller, knife, sampling, test plates floating roller clamp, non-standard fixtures

Product Features

1, the structure and operation principle mechanical parts
Mechanical loading, driven by a motor reducer, drive power transmission screw moves up and down the middle of the crossbar, the crossbar above and below the beam with two fixtures to achieve tensile specimens, compression test.

2, the measurement characteristics and working principle parts
Using computer-controlled, high-precision load cell, high-precision AD conversion and imported photoelectric encoder with intuitive display, easy operation, accurate data and so on. Provide on-site calibration and peak hold function.
Universal testing machine works: testing machine loading force sensor generates electrical signals and sent to the AD converter, while the screw is rotated to drive the encoder generates a pulse signal input microcomputer together, the test results will be displayed on the control to adjust the computer screen come out.

Tensile testing machine speed adjustment:

1. first record crossarm of the initial location, on the Control Panel, select the speed value (using a standard ruler for measuring cross arm stroke).

2. starter electronic stopwatch start timed one minute stopwatch to time the machine stop button is pressed at the same time, according to the stop watch time, record the crossarm throttle value is a per-minute rate (mm/min), observe the cross arm stroke difference between value and the vertical ruler, and calculates the cross arm stroke error values should not exceed ± 1%.

Precision Alignment
1) initial alignment
2) tensile testing machine-precision alignment
Anchor nut cast solid, prior to the dry cement, no anchor fastening nut and switch on the machine. (Cement drying time is generally not less than 10-15 per day) for cement dry completely, nut fastened good luck foot, to review the test installation of precision, is compatible with the alignment accuracy. If it does not meet should be looking for.
In the tensile testing machine, due to vibrations are prone to loosening when testing, tensile testing machine after a period of use, relevant parts should be fastened.

Host Maintenance:
1, the machine should be coated with anti-rust oil jig custody;
2, since the jaw hydraulic universal testing machine is often used, easy to wear, when the scale too much, easily lead to damage to the small piston oil spills, so jaw Department should be cleaned regularly to keep clean (preferably after every test done for cleaning );
3, the sliding surface inlay plate and liner contact surface of the dovetail groove on the liner should be kept clean, regularly coated with a thin layer of MoS2 (molybdenum disulfide) grease;
4, periodically check the jaw parts of the screw, if found loose, tighten timely;
5, regularly check the drive sprocket situation, if there is loose, re-set the tensioner tension;

Oil Source Maintenance:
1, periodically check the host and the oil spill at the source has a place, if there is leakage, seal rings should be replaced, or a combination pad;
2, according to the time and the use of the machine oil, regular replacement of filters and suction filter, replace the hydraulic oil.
3, a long time do not do the test, pay attention off the mains. If the machine is in standby mode, the switch should hit the "load" file, because if the switch is on "rewind" position, solenoid valve has been energized, it will affect the life of the device.
