Cost-effective brick pressure testing machine, automatic pressure strength testing machine
Cost-effective brick pressure testing machine (electro-hydraulic servo pressure testing machine) is mainly used for the compressive strength test of bricks, stone, cement, concrete and other materials, as well as the compressive performance test of other materials. The series of pressure strength testing machine developed by the company adopts computer fully automatic control, measuring sensors (pressure sensor, displacement sensor, deformation extensometer), servo valve, controller (each signal conditioning unit), and servo amplifier form multiple closed-loop control loops. , To realize the closed-loop control function of the test force, cylinder piston displacement, and sample deformation of the testing machine; it has multiple control modes such as constant rate test force, constant rate cylinder displacement, constant rate strain, etc., and can realize the smooth switching of control modes, so that The system has greater flexibility.
YAW series full-automatic pressure testing machine main unit adopts the under-mounted oil cylinder, and the oil source adopts piano-type hydraulic oil source. Compared with other brands of pressure testing machines, the outstanding advantages are: the upper pressure plate space adjustment method: electric lifting; the oil cylinder adopts special technology, honing processing, gap sealing, strong sealing, long service life; high-precision full-digital servo valve, imported high pressure The oil pump has low noise and stable operation.
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.
