What are the steps for debugging the universal testing machine?
When purchasing a universal testing machine, many customers choose from thousands of choices. Both the quality of the equipment and the measurement accuracy will be well understood, and the price of the equipment is also compared with many manufacturers. After purchase, the universal testing machine equipped with a microcomputer printer needs to be debugged before use. The accuracy of the test data is determined through the debugging, and each link of the universal testing machine is calibrated. After the debugging is completed, it can be carried out. Normal test. The debugging of the universal testing machine is mainly divided into the following six steps. Today, the editor of the testing machine will share with you the debugging process of the universal testing machine. (1) Pull the cold-formed support to both sides equidistantly, so that the moving beam does not touch when lifting; (2) Turn off the oil pump motor, unscrew the MS plug on the oil pump, and discharge the air in the pump (and A small amount of oil will flow out together), and after the air is drained, turn back the plug: start the oil pump and repeatedly lift the piston to drain the air in the oil cylinder and oil pipe. (3) Check the oil pipe joints for oil leakage; (4) Install the spherical lower plate on the table, move the cross beam up and down to make the upper and lower plates about 20mm apart; (5) Start the oil pump, close the oil return valve and open the oil delivery valve to make the table As the plate rises, slowly increase the pressure; (6) If there is oil leakage, tighten the oil joint after releasing the force.

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.
