How to choose a tensile test machine

How to choose a tensile test machine? In addition to considering the price when choosing a tensile test machine, customers will also consider the quality problem of tensile test machines. Of course, the cost -effective is of course high. Here are the factors to select the selection of tensile test machines.

 

Factors 1. The price of the tension test machine

The problem that the customer cares about the general ZUI is the quality and price of the tensile test machine. The impact on the price is mainly: force sensors, material tube fixtures, body and tensile machine ldquo; transmission function ldquo;. There are two types of general transmission functions, 1: screw transmission; 2: rack transmission. Generally, the price of screw transmission is more expensive than the price of rack transmission. It is used for high -precision and testing high -precision materials.

Factors 2. Various measurement systems of the tensile machine

Generally, the measurement system that constitutes the tensile test machine is:

The system, which is measured by measuring sensor, amplifier, and data processing system;

 

B: The measurement system for deformation of the material, it is a deformation measurement device to measure the deformation of the sample during the test;

C: The measurement system of the transverse beam displacement, it obtains the displacement of the beam by measuring the number of output pulses of the optoelectronic encoder; , To change the movement speed of the beam;

E: ZUI's important control system is the control system. On the microcomputer;

 

Factors 3. The quality of the tensile machine pipe clip

 

Factory manufacturers of normal production of tensile machine clips have passed the certification standard, and only good quality Only the pipe clip can firmly fix the test materials, so that the results of the test results will be small;

Factors 4. The speed of tension during the test

 

Test the test The speed of time needs to be controlled on the microcomputer software for control, then strictly executed according to the input data;

Factor 5. The degree of the microcomputer software analysis data

 

The force value analysis software independently developed by Li Gao not only has a high degree of high degree, but also printed these data to prepare for a reference for future;

Factors 6. Applicable material range

The range of normal tensile test machines is wide. When testing different materials, we can replace the corresponding clamps and force sensors. Therefore, as long as the tension test machine meets all the above conditions, then you can rest assured to purchase.
