How to keep the hydraulic universal testing machine clean
How to keep the hydraulic universal testing machine clean
Hydraulic universal testing machines have very high accuracy requirements. If the hydraulic universal testing machine cannot be guaranteed to be clean and dust-free, if dust enters the hydraulic system, it will cause very serious consequences such as clogging the valve hole and scratching the surface of the piston. Therefore, we The hydraulic universal testing machine should be kept clean, so in addition to cleaning the surface dust, what else do we need to do? With this question, let us take a look at the following content. 1. Regularly check the screws in the jaws, if they are loose , Tighten it in time; 2, check the transmission of the sprocket regularly, if you find any looseness, please re-tension the tensioner; 3, the hydraulic universal testing machine will inevitably generate some dust during the test, such as oxide Metal chips, etc., will not only cause wear and scratches on the surface of some parts; 4, the fixtures of the hydraulic universal testing machine should be coated with anti-rust oil for storage; 5, the jaws of the hydraulic universal testing machine Frequent use, it is easy to wear, and it is easy to cause damage to the small piston and oil leakage. The jaws should be cleaned frequently and kept clean; 6. Thin layer of molybdenum disulfide grease.
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.
In order to prevent accidents, safety protection devices are installed in the design of the testing machine.
