Main installation method of WAW series microcomputer controlled hydraulic universal testing machine
WAW series microcomputer controlled hydraulic universal testing machine and the oil source are respectively transported to the concrete foundation, and the distance and direction between the main engine and the oil source are determined according to the appearance drawing, foundation drawing, and the size of the oil pipe. Then use a thin plate to pad between the bottom of the host and the foundation. Then use a 0.05/1000 square level meter for alignment. Place the square level meter on the outer surface of the cylinder and align the verticality on the two sides that are perpendicular to each other. Its verticality should not be greater than 0.2/1000. Or put the strip level meter on the workbench and correct its levelness. The levelness should not exceed 0.2/1000.
After the testing machine is aligned, pour the anchor nut with cement, and secure the shim under the machine base. And use cement to fill all the voids under the machine base to keep the machine base and the cement base in good combination, and prevent the test machine from being unlevel due to vibration during use. After the anchor bolts are poured, before the cement is dry, it is not allowed to use anchor bolts to fasten the testing machine and start the host (the cement drying time is generally not less than 10-15 days). After the cement is dry, use the anchor bolts to fix the testing machine On the basis of the. Recheck the installation accuracy of the testing machine to see if it matches the alignment accuracy. If it does not meet the requirements, re-align it.
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.
