The difference between electronic universal tensile testing machine and hydraulic universal tensile testing machine
Tensile testing machine can be divided into electronic tensile testing machine and hydraulic tensile testing machine according to the working principle. The electronic tensile testing machine is mainly powered by a servo motor and completes the lifting of the testing machine through the transmission system, thereby performing tensile testing on the tested materials , The biggest feature of the electronic tensile testing machine is low noise, no pollution, and high equipment accuracy.
According to the space, the electronic tensile testing machine can be divided into two working modes: single-phase tension and pull-up and compression. If the customer has no special designation, it will generally be shipped according to the standard model with space tension and compression. This type of model is generally tested for small-ton tensile testing. The testing industry includes plastics, rubber, paper, non-woven fabrics and metal materials with general strength. The test force ranges from 100N (or less) to 10,000 N (or greater) ). The only disadvantage is that the purchase cost is higher than the hydraulic testing machine.
Compared with the electronic tensile machine, the hydraulic universal testing machine is driven by a hydraulic cylinder on the working principle. Generally, the test force of 30 tons (including 30 tons) or more will use this model, such as high-strength bolts, steel bars, electrical fittings, etc. This kind of equipment will be used, and its characteristics include low purchase cost of the whole machine, strong applicability of working conditions, and long replacement cycle.
There are many types of hydraulic universal testing machines, and customers can have more choices. If you only do a simple tensile strength test, then you can consider the digital display. One can save the budget, and it can also be used later. Upgrade and transformation; if there are many test contents, such as yield strength, elongation, etc., then it must be controlled by a microcomputer. Although the cost is higher, it will be more convenient to use.

Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
